Shuchi'in Academy High School

High School Student Council ^noteTaikoku Takano
Second-Years ^note

Faculty

Adolphe Pescarolo

Voiced by: Itaru Yamamoto (Japanese), Jeremy Inman (English), Hélio Ribeiro (Brazilian Portuguese)

Debut: Chapter 14 (Manga), Episode 4 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/adolphe.png

The current principal of Shuchi'in High School and the former principal of its sister school in France.

Adaptational Late Appearance: The anime cut out his first scene where he confiscated Karen's magazine, so he isn't introduced until the French party.
Bunny-Ears Lawyer: He wouldn't be the principal if he wasn't competent. He nonetheless plays Pokémon GO in school and the photo shoot in Chapter 100 shows his eccentric character.
Connected All Along: Turns out that he's Gigako's grandfather.
Dirty Old Man: His words of praise during the photo shoot in Chapter 100, where he especially showers the girls with compliments, reveal a more perverse side of his.
Everyone Calls Him "Barkeep": While his name is shown in several places (like Shirogane's letter of recommendation), none of the characters ever refer to him as such.
Famous-Named Foreigner: Him having the same last name as former racing driver and businessman Henri Pescarolo very likely is a case of that trope, because NOTHING matches in the real counterpart.
Foreign Exchange Student: He attended the school as an exchange student 40 years before the events of the story.
The Gadfly: He definitely seems to enjoy messing with people, as seen in his various interactions with the student council.
Hypocritical Humor: He plays Pokémon GO during school hours, but scolds the Tabletop Gaming club for doing the exact same thing. Also doubles as Parental Hypocrisy, given that he's Gigako's grandfather.
Poirot Speak: The anime has him pepper his dialogue with bits of random French.
Reasonable Authority Figure: Despite being rather eccentric, he's generally fair to his students and at least able to keep order when the students and their own eccentricities bring havoc. Also, he set up the entire class 3-A where Kaguya is surrounded by her close friends just so that she can have an entire class to support her when she need them the most.
Secret-Keeper: Seeing as how the principal let Ishigami attend high school and laughed about his "reflection", it's very likely that he is aware of Ko Ogino's true character and Ishigami's intentions in middle school. Given that his granddaughter is confirmed to have been among those that Kaguya told, he probably learned it from her.
Shared Family Quirks: Both he and his granddaughter are fans of Pokémon GO.
Stealth Mentor: He enlists Betsy's help to test Shirogane's worthiness of his presidential position during the French Exchange, but it backfires due to Shirogane's inability to understand Betsy's insults. In Chapter 239, he explains why; to prepare Shirogane for the task of protecting Kaguya and the school when the Shinomiya and Shijo groups inevitably go to war.
Token White: He's the only Westerner among the cast (discounting Betsy, Hayasaka, and his granddaughter).
What the Hell Is That Accent?: Thanks to being a native Frenchman who attended Japan as an exchange student before becoming principal, he speaks with an obvious French or at least non-Japanese accent even without the random bits of foreign dialogue. Despite his age, it still sounds akin to a European reading Japanese off a script without much prior experience.
Yellow Eyes of Sneakiness: The anime gave him yellow eyes to underline his role as The Gadfly.

Hikaru Oobayashi

Debut: Chapter 211

Kaguya and Shirogane's homeroom teacher in their third year.

Back for the Finale: He makes a brief appearace in Chapter 281, letting Shirogane (who dropped out to attend Stanford and thus is technically not allowed on the school grounds anymore) stand with the teachers during graduation so he can get a better view of Kaguya recieving her diploma.
A Day in the Limelight: Chapter 225 is told from his perspective, with his attempts to be a responsible teacher towards Kaguya (and her completely misinterpreting it).
Good Smoking, Evil Smoking: He uses an e-cigarette, showing that he's somewhat gruff but also rather young.
Help Mistaken for Attack: His first attempt to offer advice to Kaguya leads her to assume that he's attempting to either blackmail or seduce her, similiar to how Ishigami mistook her trying to help him study for torture.
Junior Counterpart: Inverted. He's basically an older Ishigami in terms of appearance and general demeanor, something that's further reinforced by the fact that he falls for a teacher that seems to be a hybrid of Iino and Tsubame.
Secret-Keeper: Downplayed. He's the first person outside of Kaguya and Shirogane's immediate social circle (and the Mass Media duo) to find out about their Secret Relationship, though by that point they've already started to be more open about it.

First-Years

Class 1-A

Kozue "Makki-senhai" Makihara

Voiced by: Marika Kouno (Japanese), Emi Lo (English)

Debut: Chapter 29 (Manga), Episode 13 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/kozue.png

The sadistic "Dictator for Life" of the Tabletop Games Club.

Adaptational Late Appearance: The anime cuts out her initial cameo from Chapter 29, so she doesn't appear until the adaptation of Chapter 57 at the beginning of season 2.
Ambiguously Gay: She has shown no romantic interest towards anyone, though she does comment on how cute Iino is and playfully bites her ear during their attempt to test some horror sounds for their haunted house stall.
Blessed with Suck: She has incredibly high emotional intelligence and can pick up on others' relationships unnaturally easily. This unnerved a lot of people, which led to her developing trust issues prior to joining the Tabletop Games Club.
Curb-Stomp Battle: Even with Fujiwara's backing, Iino crushed her in the presidential election following Shirogane's departure, getting a measly 8 votes compared to Iino's 561.
The Dreaded: The Mass Media Club duo refer to the Tabletop Games Club as a "den of evil". She has a particularly bad reputation due to her sadistic personality. Which might be why she ended up doing so poorly when she tried running for student council president.
Epic Fail: She got 8 votes out of 673 when she ran against Iino for student council president. The sadism and eccentricity probably had something to do with it.
Gamer Chick: She's a member of the Tabletop Games Club.
Genius Ditz: Makki-senhai may be eccentric, but she's actually one of the top 10 students of her year, with her standing even going up by one rank during the 2nd semester's final exams. She was also the only person who figure out that it was a member of the student council who took all the heart balloons without having direct insider knowledge.
Ironic Nickname: "Senhai" was originally "senpai" but the "pa" was stolen in a punishment game. She's actually a freshman.^Explanation
Karma Houdini Warranty: It takes over half a year after the fact, but karma would eventually pay Makki-senhai a visit for her BDSM torture of Iino by having the latter defeat her in the student council election by a 500+ vote margin.
A Mother to Her Men: Parodied. During the sports festival, her club prepared randomized beverages, apparently to so amuse the competitors while hydrating them. None of them went along with the idea, though ^noteexcept Tsubasa, so Makki drinks one herself.
(coughing) "I am the TG Club's eternal president. I can't waste something you put this much effort into...That is all."
- Turns out it was just miso soup. She's fine.
Nightmare Fetishist: She has an unhealthy love for horror. Case in point: her idea for the culture festival was a school-wide battle royale deathmatch.
Only Known By Her Nickname: She rarely goes by her real name.
Otaku: She is a "mega otaku" according to Fujiwara.
Sadist: She basically subjects Iino to softcore BDSM when they were recording ASMR for their class's haunted house, and was clearly loving every second of it.
Those Two Guys: Rarely seen without Gigako.
Took a Level in Cheerfulness: Apparently, she used to be a lot more closed off prior to joining the Tabletop Games Club.
Young and in Charge: She is the "Dictator for Life" of the Tabletop Games Club, despite being a first-year. She presumably won the title by beating Gigako (the club's founder) in a board game. Apparently the power went to her head, as she decided to shoot for student council president after Shirogane left for America. She failed. Spectacularly.

Class 1-B

Yu Ishigami

Miko Iino

For more info about her, see her page.

Kobachi Osaragi

Voiced by: Rina Hidaka (Japanese), Leah Clark (English), Vanessa Scorsoni (Brazilian Portuguese)

Debut: Chapter 65 (Manga), Episode 12 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/osaragi.png

Miko Iino's childhood friend who serves with her on the Shuchi'in Disciplinary Committee and acted as an assistant for her presidential campaign. Prefers to watch from the sidelines.

Adaptational Early Appearance: She can be briefly seen during the credits sequence of the anime's first season finale, which is set 19 manga chapters before her introduction.
Affectionate Nickname: Iino calls her "Koba-chan".
All of the Other Reindeer: Osaragi describes herself as a pariah amongst the other girls in school in Chapter 189.
Bad Guys Do the Dirty Work: Invoked on herself. Osaragi takes the secret student council file about Ishigami and gives it to Tsubame because she supports their relationship. She tells Kaguya that, since it would have strained the relationship between Ishigami and the rest of the council if one of the council members had done it, she decided to do it herself.
Osaragi: The perfect role for the perfect pariah, wouldn't you say?
Batman Gambit: Played for laughs. Iino and Ishigami don't get along, so in Chapter 103 Shirogane proposes several activities that are supposed to make them become friends. As all attempts fail, Osaragi points out the Belligerent Sexual Tension between them with a "Not So Different" Remark to end this farce. The two of them quickly deny Osaragi's observation by claiming in front of Shirogane that they actually like each other, just as Osaragi expected they would behave.
Beautiful All Along: The reader cannot see her face behind her Opaque Nerd Glasses and stereotypical geeky looks, but in-universe she is viewed as a very attractive woman both by the boys in school and her female friends. Her face is shown in full at the end of chapter 231, and she is indeed very pretty.
Because You Were Nice to Me: Her middle school life was full of people who resented her for her good looks. The few people who managed to help her through this phase were Iino, Otomo, Ishigami, and Tsubame and it's due to their kindness that she's incredibly loyal to all of them. She now supports the relationship with Ishigami and Tsubame, despite having developed feelings for him.
Beneath Notice: Next to a loudmouth firecracker like Iino, not many people notice Osaragi, which is just the way she likes it. She knows the downside of fame all too well.
Birds of a Feather:
- Osaragi sees herself as a kind of pariah, which is why she can take on the role to tell Tsubame the truth about Ishigami's past without any damaging consequences. Kaguya points out that Ishigami and Osaragi are thus very similar, which Osaragi agrees with.
- Tsubame offered Osaragi help in middle school, as both were resented by people who were jealous of their looks and achievements. Tsubame then advised Osaragi to brush off their compliments with an indifferent "thankful" reply, and told Osaragi to lean on her if she ever needed to.
- Iino is another social pariah, as her obsession with the rules makes her fairly unpopular, which is largely why she and Osagari bonded and became friends in the first place. However, with Iino getting more popular and the two of them conflicting over Iino's crush on Ishigami, Osaragi starts to feel that they were only ever friends in name only, and without a shared social status they have nothing in common.
Brainless Beauty: She's considered to be one of (if not the) most beautiful girls in school, yet her ranking on the end-of-semester exams is pitiful (she actually ranks below Ishigami). Given the fact that she's actually shown to be rather observant otherwise, it might be a case of her just not caring about academics, but nothing concrete is ever stated.
Broken Bird: Chapter 192 reveals that Osaragi used to be a cheerful and outgoing person, but this all changed when the tabloids published the news that her mother cheated on her husband, making Osaragi the subject of Condescending Compassion in addition to the jealousy other girls showed her in middle school. Since then, she has become more introverted.
Broken Pedestal: In a way, towards Iino. She silently supported Iino and Ishigami as a pair in middle school despite having feelings for the latter due to them fulfilling what her ideal romantic relationship looks like. However, when Iino doesn't take Ishigami's side when he gets ostracized, Osaragi becomes deeply disappointed in her for not repaying all of Ishigami's efforts to help her out (despite Iino not being aware of said efforts in the first place), and has grown to resent her ever since.
Cannot Spit It Out: Osaragi never gains the courage to tell Ishigami about her feelings for him. It's confirmed in Chapter 232 that she refrained from doing so in middle school because she saw how much more compatible Ishigami and Iino are and tried to make way for them, and in high school she notices that Ishigami has fallen for Tsubame. The closest thing she gets to a confession is her admitting in Chapter 192, that she has known his true self for a long time, and wishes for his happiness.
Childhood Friends: She's been friends with Iino ever since elementary school.
Cloudcuckoolander's Minder: Most of her on-screen interactions with Iino have her reigning in her friend's overactive imagination. She mentions during the end of the culture festival arc that she's going to try to stop doing this as often, as she feels that it's keeping Iino from growing up.
Condescending Compassion: A victim of it in middle school. After her mother's affair was revealed, lots of female classmates might have said they were sorry but their tones said they thought Osaragi deserved it due to their jealousy of her beauty.
The Confidant: Acts as this to Iino, who tells her everything that's troubling her. However she avoids doing so when Iino needs advice about her conflicting feelings for Ishigami without making it obvious to her. The reason is that Osaragi has placed Ishigami's happiness over everything else, and she's not going to risk his chances of him getting together with Tsubame by helping Iino.
Conflicting Loyalty: Chapter 192 shows the dilemma Osaragi is in. On the one hand, she would like to support her Childhood Friend Iino, but Iino has fallen for Ishigami, for whom Osaragi herself has feelings for, and he is in love with Tsubame, who has also helped Osaragi out in the past. Osaragi prioritizes Ishigami's happiness over everything, though, thinking that he has made the "right" choice in falling for Tsubame, which is why she supports his potential relationship with her.
Courtly Love: Her admiration of Ishigami is more philosophical than physical (although there's a bit of the latter too) and she feels similarly about the girls who also helped her.
Ishigami: The unconditional love within each person's chest...why can't people realize that's what true love is?
Covert Pervert: When Iino complains that (she thinks) Shirogane and Ishigami use the student council to take advantage of its female members, Kobachi suggests "joining in on the fun", and describes it as "a pretty hot situation". This could be yet another piece of Foreshadowing about her unrequited feelings for Ishigami.
The Cynic: Her thoughts on mob mentality are rather depressing, as she witnesses how Ishigami is ostracized by the female first-years. Osaragi later implies that she is also a pariah in school, as she was harassed after her mother's affair became public, on top of all the jealousy, hatred, and insincerity other female students showed her in middle school.
A Day in the Limelight: Chapter 85 features a day in the life of her role as a member of the disciplinary committee. Chapter 192 is also told from her perspective and reveals a major part of her past. Chapter 232 has her disclose to Kaguya her perspective on Ishigami and Iino's relationship in middle school.
Deadpan Snarker: Basically Iino's straight-man, although she has her own quirks.
Disappeared Dad: The fanbook lists her mother as her only relative. Chapter 192 implies that her father left after news of her mother having an affair was published in a tabloid.
Dude Magnet: Onodera reveals in Chapter 158 that Osaragi has a lot of boys fawning over her, including guys from other schools who wait at the gate just for a chance of catching a glance at her or asking her out.
Fallen Princess: Seeing the malice of people when her family broke up almost embittered her. Except she also saw that some people were truly good.
Foil: Chapter 192 reveals her to be one to her best friend, Iino:
- Their issues are the result of their families: Iino's self-righteous attitude and starvation for affection is due to her parents' busy schedules, while Osaragi's status as a pariah is due to her mother's affair as well as her beauty that she inherited.
- They are both pariahs who were especially bullied in middle school, but while Iino was able to get through with her personality mostly intact, Osaragi became heavily introverted as well as distrusting due to it.
- Both are weak to people that are kind to them, but while Iino is weak to any compliments no matter how obviously fake they are, Osaragi is completely loyal to the few people that helped her in her darkest hour.
- They both have a crush on Ishigami due to minor things he's done: Iino is crushing on him unknowingly due to a simple letter and flower he sent her as well as him checking up on her during the culture festival with pictures of people enjoying the bonfire she worked so hard to get approved, while Osaragi fell for him due to him protecting her from some bullies as well as his general kindness.
- They're both similar to their crush but in different ways which changes how they interact. Iino has similar ideals of altruism and is just as stubborn but that makes them argue each time they meet because they're too similar. Osaragi is just as observant and distrusting of others which allows them to interact peacefully on the rare occasion they cross paths.
- They have exact opposite reactions to Ishigami's crush on Tsubame. Iino gets deeply jealous over it and early on tries to get in their way compared to Osaragi's full support.
Former Child Star: Chapter 192 shows that she was an outgoing and lively Child Popstar, but her mother's affair and not having the social skills to deal with her classmates' resentment led to a terribly depressing time in middle school.
Given Name Reveal: Despite being introduced in and a recurring character since Chapter 65, her name wasn't revealed until Chapter 85.
Green-Eyed Monster: In Chapter 232, she admits to Kaguya that she's always been incredibly envious of Iino for being Ishigami's Protectorate, and claims that if she were in her position she would have taken his side and believed in him when the Otomo incident happened.
Hyper-Awareness: As she has known Iino since elementary school, she knows her friend quite well. She also pays a lot of attention to Ishigami, after he defended her in middle school. This is why she knew he was the one who sent Iino the letter and flower that showed Iino the appreciation she desperately craves.
Hypocrite: She disapproves of Iino's attempts at trying to get closer to Ishigami early in their second year as she sees it as Iino taking advantage of Ishigami's feelings after Tsubame rejected him not too long ago. This, coming from the same girl who encouraged Ishigami to take advantage of Tsubame's weakness to pressure so Tsubame wouldn't reject his confession a few months back.
- She's actually aware that she's one, admitting that while her resentment of Iino is due to the latter not taking Ishigami's side when the Otomo incident happened (at least initially), she didn't actually do anything to help him either, which explains that for the same reason she vetoes Iino as Ishigami's girlfriend, she forbids herself.
I Just Want to Have Friends: She is as deeply interested in her peers' lives as your average teenage girl, but she fears the vulnerability that true friendship entails. From a distance, she can steer them in the direction she wants without risking attachment.
Indifferent Beauty: She has a rather nonchalant attitude towards the fact that boys find her attractive, so much so that the audience doesn't learn about it until almost 100 chapters after her introduction. This kind of attitude was recommended to her by Tsubame, who faced similar problems of resentment.
Informed Attractiveness: Used as a joke when both Iino and Onodera comment on how beautiful she is. Since her glasses are drawn opaque and cover most of her face, readers can't tell. In fact, she is known as one of Shuchi'in High's four "Impossible Girls", the most beautiful girls (excluding the student council members) that are impossible to date.
Insecure Love Interest: Osaragi started looking at Ishigami after he defended her against bullies in middle school. She seems to hold back her feelings because she thinks Ishigami made the right choice in choosing Tsubame. Even back In middle school, Osaragi assumed Ishigami was interested in Iino after she saw him sending Iino the letter.
Intentional Heartbreaker: One of her reasons for going out with Kazeno may have been so he wouldn't get in the way of Ishigami asking out Tsubame.
I Want My Beloved to Be Happy: Chapter 192 reveals that, while Osaragi has feelings for Ishigami, she decided to not act on them, after seeing that Ishigami was the one who sent Iino the flower and letter that she treasures above all. When she learns that he is interested in Tsubame, she tries her best to make him happy, and supports him without his knowledge.
Jerkass Ball: Actively attempting to get Ishigami and Tsubame together despite knowing Iino has a crush on the former is a pretty mean thing to do to her best friend. As can be seen in Chapter 190, she also refuses to talk with Iino about her clearly hurt feelings, instead openly stating that she ships Tsubame and Ishigami. And even after her ship fell through, she still refuses to support Iino's efforts to get closer to Ishigami, and badmouths her behind her back. It takes Kaguya's intervention to get her to see the error of this mindset.
Jerkass Has a Point: While claiming in Chapter 229 that she still can't support Iino's crush on Ishigami even after her own preferred ship fell through may sound like a horrible thing to say regarding her best friend, both of the points she makes on why she can't (Ishigami would just be On the Rebound and Iino is trying to take advantage of the situation) are completely valid.
Love Makes You Evil: Chapter 192 reveals that Osaragi has feelings for Ishigami and wants to help him gain happiness by helping him get into a relationship with Tsubame. While not certain, her sudden and short-lived fling Kazeno may have been intended to remove him as a potential romantic rival and improve Ishigami's chances with Tsubame. She also prioritizes Ishigami's happiness over her best friend Iino's, and willingly ignores Iino's desperate need to talk about her feelings, while openly telling her that she supports Ishigami's relationship with Tsubame. Kaguya is quick to call her out on this once she finds out.
Meaningful Name: The Buddha mentioned in Osaragi's name taught that attachment (to anything, even people) causes suffering. An ethos Osaragi can surely get behind.
Minor Flaw, Major Breakup: She broke up with Kazeno because she was grossed out by his workout regimen.
Motherly Side Plait: Osaragi isn't actually a mother, though her use of the hairstyle does help reflect how she acts as Iino's Cloudcuckoolander's Minder.
One Thing Led to Another: This is more or less how she started dating Kazeno, though there (probably) wasn't any sex involved.
Only Friend: Iino didn't have anyone but Osaragi before joining the student council. In Chapter 137, Osaragi mentions that she acts a bit too overprotective towards Iino and wishes that Iino becomes more independent, so she can grow.
Only Sane Woman: She's level-headed and perceptive, which gives her a generally accurate picture of the rest of the cast and lets her cut right through the comedic misunderstandings. When Iino came to her claiming that the student council was some kind of weird sex club, Osaragi pointed out how out-of-character that sounded and encouraged Iino to re-evaluate the situation. She's also observed what kind of person Ishigami really is (like seeing him quietly pull a mocking sign off Iino's back), and as a result doesn't believe the rumors that he's a violent stalker.
Opaque Nerd Glasses: Her eyes have never been seen in story (though half of her right eye is visible on the cover of Volume 17). This doesn't keep her from being considered a Dude Magnet (despite a yonkoma packaged with the anime's DVDs stating it's the entire reason she wears them). A side view of her face can be seen in Chapter 192, right after she gave Ishigami a roundabout confession. Osaragi's face is clearly seen for the first time at the end of Chapter 231, after she opens up to Kaguya.
Opposites Attract: She's a somewhat quiet girl, not the sort of person you'd expect to be dating the captain of the cheer team. Of course, it's likely that she never had any interest in him to begin with and was only dating him so he wouldn't be a threat to Ishigami asking out Tsubame. Once that goal has been achieved, she promptly dumps him.
Prophetic Name: She's named after the Begging Bowl of the Buddha, which Ishidzukuri no Miko (Iino's namesake) was tasked with collecting. In the original story, Ishidzukuri no Miko presented Kaguya-hime with a fake bowl because he couldn't find the real one, much like how her and Iino only became friends because they couldn't get "real" ones.
Psychological Projection: The real reason behind her Shipper on Deck support for Ishigami×Tsubame. It's confirmed in Chapter 231 that Osaragi sees Tsubame a successful version of herself — that is, someone who had the same kind of envious attention she suffered from in middle school focused on her, but was able to handle it without making it into her Cynicism Catalyst — and considered seeing Tsubame in a relationship with Ishigami to be the closest Osaragi herself was going to get to having her feelings for him fulfilled.
Really Moves Around: While she's presumably never lived outside of the Tokyo area given that she's been attending Shuchi'in since childhood, she nods in agreement when Koromo mentions how people in the entertainment industry have to regularly move to avoid stalkers.
Refusal of the Call: Shirogane offered her the position of General Affairs Officer after his reelection, but she turned him down, as she had no interest in being on the council. The position remains unfilled for the entire term. And when Iino is elected President in the following school year, she once again turns down the offer.
Scary Shiny Glasses: Osaragi is The Faceless, due to her glasses. As her eyes are hidden, it's difficult to see her emotions outside of the rare smiles she shows (which are often directed at Ishigami). A part of her eyes can be seen in the Volume 17 cover, though, and in Chapter 192 a clear side view of her face is shown when she tells Ishigami that she wishes for his happiness. Her face is clearly shown at the end of chapters 231 and 232, reflecting how she's finally opened up about her emotions and insecurities to Kaguya.
Secret-Keeper:
- Osaragi took the secret student council report about Ishigami and then gave it to Tsubame, so she is fully aware of what exactly happened between Ishigami and Ogino in middle school.
- Up until Chapter 192, she was a Secret Secret-Keeper to Ishigami. Osaragi tells him that she knew he was the one who sent Iino the encouraging letter and the flower back in middle school. It's implied that she didn't tell Iino because of her own feelings for Ishigami.
Seen It All: She is accustomed to Iino's tendency to make mountains out of molehills.
Shadow Archetype:
- To Ishigami. Osaragi is a victim of mockery and an Otaku, who hides behind her appearance and shut the world out, which is why many people appear or used to appear like The Faceless to her, just like with Ishigami. Like him, she can be very observant and wants to support her loved one without their knowledge. Even their Leitmotifs are similar, and they placed similarly in the exams in Chapter 105, with Osaragi being 151st and Ishigami being 152nd. However, Ishigami moved on from his insecurities and asked his crush out, which is something Osaragi wasn't able to do. He also puts an effort in to socialize more, while Osaragi still appears to be very introverted.
- Also to Tsubame, with both being one of the beautiful "Impossible Girls" in school, but unlike Osaragi, Tsubame is The Social Expert, who was able to withstand the jealousy of others and remained cheerful, while Osaragi became more introverted and cynical. Osaragi herself is well aware of this, and later admits to shipping Tsubame/Ishigami as a means of Psychological Projection.
- Chapter 231 reveals her to be one to Kaguya as well, representing who she'd be if she didn't care about Fujiwara as a person, and only befriended her for the sake of having friends, or if she didn't stop seeing her as a rival for Shirogane's attention.
- Towards the end of the story, she ends up as one to Maki; Maki was unwilling to hurt Kashiwagi's feelings just for the sake of having her boyfriend, while Osaragi bluntly and staunchly refused to let Iino get close to Ishigami, hurting their friendship.
Shipper with an Agenda: She seems to ship Ishigami and Tsubame, going so far to give Tsubame the secret report the student council made about Ishigami and the reason for his actions in middle school. She does this, despite being aware of the Belligerent Sexual Tension between Ishigami and her best friend, Iino, and Iino's growing feelings for Ishigami. Chapter 192 shows how Tsubame helped her dealing with the envy of her classmates, and how Ishigami defended Osaragi from others talking behind her back. She thus decided that Ishigami, whom she has feelings for, made the right choice to fall for Tsubame and court her.
Osaragi: invokedIshiTsuba is absolute! I'm on this ship and never getting off!
Shipping Torpedo: While she does want Iino and Ishigami to get along, she's against Iino realizing that she's in love with him because she ships Ishigami with Tsubame. Chapters 231-232 also show that she doesn't want them to become a couple because she's jealous of Iino, and believes that she doesn't deserve Ishigami due to not siding with him when he was ostracized in middle school.
Single-Target Sexuality: It's implied that the reason why she's considered to be a member of the "Impossible Girls" is because she's only romantically interested in a single person, specifically Ishigami.
Single Woman Seeks Good Man: Chapter 192 has her indirectly admit that she likes Ishigami because he defended her in middle school when people ridiculed her behind her back as well as his kindness to everyone, such as him helping her best friend Iino behind the scenes.
Smart People Wear Glasses: Inverted. Despite wearing Opaque Nerd Glasses and sometimes showing that she can be very observant when it comes to other people, she's actually among the bottom quarter of the freshman class in terms of grades. Then again, Hayasaka's Flash Forward has Ishigami mention that she's attending grad school, so her grades must have improved later on.
So Beautiful, It's a Curse: In Chapter 192, Osaragi describes herself as a girl who couldn't handle the jealousy other girls showed her, until she got fed up with it and hung out with the boys, which only made things worse until she was isolated. Tsubame was the one who told her how to deal with this.
Sympathy for the Hero: She is fond of people who take initiative in improving the world, but she does not see herself as one of them. You could say she's relegated herself to being a minor character in their story.
Theme Naming: She's one of the many people named after Kaguya-hime's impossible tasks. In particular, she takes her name from Ishidzukuri no Miko (Iino's namesake)'s task item, the Begging Bowl of the Buddha (bu no miishi no hachi)^note.
The Unfettered: She does not fear her sight, and likely even wears glasses to enhance it.
Unfortunate Names: Her name can also be read as "Daibutsu"^note meaning "giant buddha" but she'd very much prefer that it wasn't.
Used to Be More Social: If one compares how she introduces herself in Chapter 85 to how she did in Chapter 192 when she was a cheery and social Child Popstar, one can easily see how the ridicule and jealousy she received in middle school took a toll on her.
Walking Spoiler: Half of her entry is whited out due to being a vastly different character than she's initially presented to be.
The Watcher: She doesn't actively participate in plots, but she does take notice of all the things going on with Iino, and the situation in middle school. Thankfully, this means she can see the good points of those who are shunned, like Iino and Ishigami. This also means she sees the Belligerent Sexual Tension between the two of them.
We Used to Be Friends: Her friendship with Iino seems pretty okay at first, but ever since Osaragi's opposition to Iino getting closer to Ishigami, the two begin drifting away from each other. This goes to the extreme by chapter 231, where Osaragi reveals her disdain of Iino to Kaguya, and Iino just so happens to walk in on the conversation. Iino calls out Osaragi's own refusal to act like a friend recently, and simply states that she has more friends now. Suffice to say, their friendship has become a hollow shell of what it used to be though they're fortunately able to resolve some of their issues by the end of the arc.
World's Most Beautiful Woman: The bonus page for Chapter 158 goes so far as to claim that she is rumored to be the hottest girl in the history of Young Jump (the magazine that the series is published).
Yaoi Fangirl: In one of the extra comics, Osaragi is seen reading a BL manga, and is quite into it.

Rei Onodera

Voiced by: Yūki Takada (Japanese), Suzie Yeung (English)

Debut: Chapter 82 (Manga), Episode 17 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/rei_4.png

The daughter of a famous jewelry company's president. Onodera is a gossipy classmate of Ishigami's, who first really becomes acquainted with him during their time on the Cheer Team. She later befriends Iino when they work together on the Culture Festival Committee.

Academic Athlete: She's both a member of the school's lacrosse team and regularly scores among the top quarter of her grade in the end of semester exams.
Adaptation Dye-Job: In the manga, she has light pink hair and blue eyes, while the anime made both of them yellow.
Armor-Piercing Question: In Chapter 230 she delivers one to Ishigami that not only makes him realize that Iino matters too much to him to not take action if there's a chance she's in trouble, it leaves him to start wondering who Iino is to him.
"Is Iino just 'someone else' to you? Are Kyoko Otomo and Miko Iino both just the same to you?"
The Atoner: Resolves to help Ishigami and Iino realize their feelings for each other as repayment for being part of both of them ending up as pariahs through her perpetuating Malicious Slander about them. A reason why of all the shippers, she's the only one presented without ulterior motives.
Bully Turned Buddy: Downplayed, as while she was never a bully per se, she did help to perpetuate Malicious Slander about Ishigami and Iino due to her love of gossip. She later befriends both of them when she gets to know them better and she ships them together.
Character Development: Due to her curious nature, Onodera was a Gossipy Hen and blindly believed rumors that she picked up on, talking badly about Iino and Ishigami behind their backs. However, after getting to know them better and becoming friends, she learned that the rumors about Iino and Ishigami are nothing but Malicious Slander that she helped spread and she in turn has become more introspective and careful regarding rumors and secrets.
Constantly Curious: She's far more stoic than most examples, though she makes a habit of learning about others' hobbies, even if it's something that she would normally never show interest in (like reading light novels). This also ties into her love of rumors, though she mentions in Chapter 172 that she's been trying to avoid spreading baseless accusations after learning how Ishigami and Iino were affected by them.
Curtains Match the Window: In the anime, she has blonde hair and yellow eyes.
Dub Personality Change: She's initially hostile to Ishigami in the manga and the initial airing of the anime to showcase the treatment he receives from his fellow first-years, but in the English dub she acts more surprised that he's acting so carefree despite what happened back then.
Early-Bird Cameo: She shows up early in the anime when Fujiwara is leading the student assembly in singing the school anthem during Episode 17 (she's the one standing next to Osaragi).
The Faceless: Her face is used as a benchmark for Ishigami's emotional state during the sports festival. Iinitally, her face is the only one visible among the cheer team as he's familiar with her as a classmate, but she becomes just as faceless as the rest of them when Otomo shows up and his depression peaks. And when he finally "opens his eyes" after the relay race, her face is the first one shown to let the reader know that things are going to be okay.
Foil: When it comes to their friendship with Iino, she serves as one to Kobachi Osaragi:
- Onodera is outgoing and social albeit still reserved, while Osaragi tends to be more withdrawn and distant towards most people.
- She's among one of the popular kids in high school. Osaragi, while known as one of Shuchi'in's "Impossible Girls", was initially a pariah in her middle school days.
- Osaragi is Iino's childhood friend and has been by her side for most of her early life, but is not supportive of her growing feelings for Ishigami, choosing instead to support a potential relationship Ishigami could have with Tsubame. As a result of that, she and Iino slowly grow distant from each other as the manga continues, and have barely hung out, at least onscreen, since Osaragi made her stance clear. Meanwhile, Onodera and Iino have only known each other for less than a year, initially had a somewhat frosty start together partly due to Onodera hearing and spreading bad rumors about her, and both come from completely different social circles, yet once they bonded and got to know each other better, Onodera becomes a faithful and supportive friend to Iino, growing closer to her as the series progresses. The big difference here that sets her apart from Osaragi is that Onodera fully supports Iino/Ishigami without any ulterior motivations whatsoever aside from wanting Iino to be happy, while Osaragi vetoes the pairing, and has other things in store for Ishigami that she thinks is best for him.
Inconsistent Coloring: Her Early-Bird Cameo in the anime had her with pink hair like what she has in the manga, but when she's properly introduced she's suddenly become a blonde.
Innocent Blue Eyes: Onodera has bright blue eyes in the manga and her Early-Bird Cameo in the anime, and the few slights she made against Ishigami and Iino were completely accidental as opposed to deliberate on her part. In the anime, however, her eyes become yellow in her proper introduction.
Lovable Jock: It's never brought up in the main series, but Chapter 180 of We Want to Talk About Kaguya shows her as a member of the school's lacrosse team, and she definitely grows into a much friendlier individual post-Character Development.
Ms. Exposition: She fills this role regarding the Iino/Ishigami/Tsubame Love Triangle. Being a member of Tsubame's social circle, she's able to fill in Iino and Ishigami with information about her that they would otherwise never learn.
Not So Stoic: In contrast to her usual demeanor, she is notably more cheerful when on the Cheer Team or the culture festival committee. Not to mention the fact that she suggested a meme as the latter's slogan.
We got dank vibes!! ~Shuchi'in is lit af~
Odd Friendship: While the two of them have almost nothing in common and come from completely different social circles, she and Iino grew rather close while on the Culture Festival committee together. Iino affectionately calls her "Rei-chan".
Ojou Ringlets: Being a Shuchi'in student, it's only natural she rocks the long-haired drill style. Though as the series went on, her hair became looser and looser until the curls were all but gone.
Perpetual Frowner: She doesn't smile much and is mostly seen wearing a neutral frown on her face.
Refusal of the Call: Iino tries to recruit her to the student council after being elected president, but she turns down the offer due to believeing that she wouldn't be a good fit for the position.
Right for the Wrong Reasons: Upon hearing Iino's Innocent Innuendo laden description of how she had spent the previous night with an older man, she comes to the conclusion that she must have gotten herself a sugar daddy. Iino was actually talking about learning how to play Apex Legends from Papa Shirogane, who has called himself "Sugar Daddy" multiple times in the past.
Secret-Keeper: She finds out about Kaguya and Shirogane's relationship after hearing the former sleep-talking about it, later getting indirect confirmation when she goes to ask her about it. The fact that she keeps it a secret from Iino when she walks in on the conversation puts her on Kaguya's good side.
She Knows Too Much: Non-fatal example. After revealing that she knows about Kaguya and Shirogane's Secret Relationship, Kaguya nearly assaults her with a taser to give her Laser-Guided Amnesia (only for her to prove that she can function as a Secret-Keeper while remaining completely oblivious to Kaguya's attempted attack).
Shipper on Deck: She ships Ishigami/Iino, something that becomes especially apparent during Tsubame's Christmas party, where she gets in between Iino and a boy who tries to flirt with her and is constantly focused on Ishigami and Iino's conversations. Notably, when a shipping war broke out between those who supported Ishigami/Tsubame and Ishigami/Iino in Chapter 189, she was the only one who had no ulterior motives.
Small Role, Big Impact: In hindsight, Onodera confronting Kaguya about her Secret Relationship with Shirogane might have significantly influenced Kaguya to reconsider her toxic thinking about subjecting potential friends to a Secret Test of Character, and how she can only truly regard Secret Keepers as friends. As Kaguya learns at the end of the class trip to Kyoto, Hayasaka has been reporting almost everything about Kaguya to her eldest brother, Oko. However, Kaguya manages to forgive Hayasaka and listen to her, and they remain Heterosexual Life-Partners.

Koromo Shiranui

Debut: Chapter 166 (Manga)

A popular first-year student, considered to be one of the most beautiful girls in school. She is the older sister of Frill Shiranui from Oshi no Ko.

Chekhov's Gunman: Her name is first listed on the end-of-semester exams in Chapter 105 right under Onodera. She is mentioned to be one of the school's four impossible girls and properly appears in Chapter 211.
Commonality Connection: She ends up becoming friends with Ishigami after the two of them meet on a gaming Discord server.
Family Theme Naming: She and her little sister Frill both have fashion themed names.
First-Name Basis: She calls Ishigami "Yuu-chin" when they meet on Discord even though he only gave his last name. Ishigami is well-known, being a member of the student council, Ootomo incident, recent new rumors about it, and they are classmates, but this level of closeness is unexpected.
Gamer Chick: Chapter 228 reveals that she's an avid online gamer. It's implied that the tired look in her eyes is due to constantly staying up late to play.
Girls Love Stuffed Animals: A single panel shot of her bedroom in Chapter 228 shows that she has at least one teddy bear.
Informed Attractiveness: She is known as one of Shuchi'in High's four "Impossible Girls", the four most beautiful and unapproachable girls in school, on par with the girls from the student council.
In the Hood: She usually wears a hooded jacket over her school uniform, which kept her features completely hidden from the reader during her first appearance.
Mistaken for Romance: While chatting with Ishigami at school the day after they're introduced to each other, some poor wording on her part leads all their classmates (except Osaragi) to assume that they're Friends with Benefits.
Really Moves Around: When Iino is suspected of having a stalker, she mentions that it's a common problem for people in the entertainment industry and that her family has had to move to new apartments multiple times in the past.
School Idol: She's considered to be "The Fairy of the First-Years" by Erika, on par with the likes of Kaguya and Tsubame. Given that Erika worships the very ground that Kaguya walks on, this is high praise indeed.
Ship Tease: Very friendly with Ishigami when they met online. She's quickly seen as a threat by Iino, while Osaragi and Onodera see the potential for her as Ishigami's girlfriend. Likely defused when she seconds Terashima who pushes Iino to go on the offensive for Ishigami.
Signature Headgear: She has two ribbons in her hair, even using a picture of one of them as her Discord icon.
Theme Naming: She's one of the many people named after Kaguya-hime's impossible tasks. In particular, she takes her name from Abe no Miushi's task item, the robe of the fire rat.
Unknown Rival: Obviously a threat as far as Iino is concerned. But it wasn't confirmed whether she sees Ishigami as boyfriend material, and it's unlikely she knows another girl is interested, and displays no hostility to Iino (quite the opposite, Koromo displayed concern when her "rival" was stalked). When she learns about Iino's crush, Koromo supports her.
Unseen No More: She's been mentioned a few times, but at most she's only been seen from behind during an Imagine Spot in Chapter 166 wearing a sweatshirt that hides everything but her hands. This is finally subverted in Chapter 211 when she finally shows up in person. It's mentioned that she works in the entertainment industry, which would explain why she doesn't attend classes often and thus was absent until then.

Third-Years

Class 3-A

Tsubame Koyasu

Voiced by: Haruka Fukuhara (Japanese), Tia Ballard (English), Mari Haruno (Brazilian Portuguese)
Played by: Haruka Fukuhara (live-action movie)

Debut: Chapter 82 (Manga), Episode 17 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/tsubame_8.png

A perky upperclassman leads Ishigami's group through sports day. Caring and energetic, she captures Ishigami's heart quickly.

Academic Athlete: She's ranked seventh among the senior class and is a member of the school's rhythmic gymnastics club.
Adaptation Dye-Job: Her hair is brown in the live-action movie.
Ascended Extra: After the sports festival arc, she gets more characterization during "Kaguya Shinomiya's Impossible Tasks".
The Bartender: Her father is a world-famous bartender, so she's presumably been taught how to prepare drinks from a young age. When she hosts a Christmas party, she spends the entire time in a waitress outfit making (non-alcoholic) beverages for everyone and even shows Ishigami how to properly use a cocktail shaker.
Beneath the Mask: While generally a cheerful Genki Girl, there is a hint that when it comes to relationships, she hides the emotional scars her previous relationship left, which is the reason for her commitment issues.
Betty and Veronica: She's the Veronica to Iino's Betty and Ishigami's Archie. She's a comparatively newer presence in Ishigami's life who has the looks, grades, and popularity to make her appear unattainable to someone like Ishigami, but this does not deter him from pursuing her anyway. The trope is inverted, though, if you consider their personalities, since Tsubame is the nice and friendly one, while Iino is strict and often abrasive towards Ishigami.
Birds of a Feather: Chapter 192 reveals that Tsubame reached out to Osaragi since she saw a connection between them in middle school, as girls who are belittled and harassed by students with an Inferiority Superiority Complex. She then gave Osaragi advice on how to handle it and offered to help if Osaragi ever needed it, which Osaragi was truly thankful for.
Cheery Pink: Her hair has a light pinkish tint. Fittingly, along with Kazeno, she's the co-leader of the Cheer Team.
Class Princess: She's near the top of her class academically, is considered one of the school's top three beauties, and is adored by pretty much everyone. She also doesn't seem to have a single mean bone in her body, is the first person outside of the student council to befriend Ishigami, and also helped both Osaragi and Ryugu when they were in similar situations. That said, she can be somewhat indecisive, and has a string of bad relationships behind her because of her looks.
Clear Their Name: She restores Ishigami's good name as a gift to make up for turning down his love confession by using her social influence to alter the narative of what happened during the Otomo incident to a more accurate (though still ultimately untrue) story.
Cloudcuckoolanguage: She has a habit of peppering her language with meaningless memes and references whenever she gets really excited. Ishigami (who had only just started to brush himself up on modern slang) is left hopelessly confused when trying to understand her during the Christmas party.
Commitment Issues: Her previous boyfriend cheated on her (and it's implied that the other girl in the equation was her best friend). Because of this, she was rather hesitant to accept Ishigami's Love Confession and ended up giving a rather lame excuse to turn him down. Chapter 160 has her admit that she was always confessed to, but never confessed to someone else. Confessions scare her, because she views them as binding contracts, and she is too indecisive to make such a decision herself.
Cuddle Bug: She has no reservations about getting in her friends' personal space when being affectionate.
The Ditherer: Insecure/Submissive type. One of Tsubame's issues is that she gets very nervous and stressed, and doesn't know what to do when she has to make important decisions like after Ishigami seriously confesses his feelings to her. She asks the people around her, like Kaguya or Shirogane's father (who works as a fortune-teller and online relationship adviser), for advice and is easily influenced. Unfortunately, her indecisiveness leads to questionable actions, like not willing to commit to a relationship yet offering Pity Sex to Ishigami, which he rejects as he doesn't want her "half-assed love".
Dude Magnet: Kaguya notes that she's very popular, as demonstrated in Chapter 115 when Ishigami is competing against three other boys for her attention.
Early-Bird Cameo: She shows up early in the anime when Fujiwara is leading the student assembly in singing the school anthem during Episode 17 (she's the only one of the third-year students whose hair isn't black).
Establishing Character Moment: She's introduced as a member of the cheer team (demonstrating her bubbly personality), but the real moment comes when she notices Ishigami sitting by himself due to not using Line and exchanges contact info with him so he can stay involved, showing that she's someone who looks out for those that others would overlook.
Even the Girls Want Her: Several girls are shown squeeing alongside Ishigami over her dance performance during the culture festival in the omakes, and she got a pile of chocolates that rivaled that of Shirogane on Valentine's Day.
The Faceless: As with the rest of the cheer team, in the sports festival arc. She only gets her face properly shown after Ishigami "opens his eyes" to the world again.
The First Cut Is the Deepest: Her previous boyfriend cheated on her and it's implied that the girl he slept with was her best friend, explaining why she was so hesitant to accept Ishigami's Love Confession (and why she thought that offering to sleep with him was a good solution).
Genki Girl: She's constantly upbeat and loves to try new things. It comes with the territory of being a member of the cheer team.
The Heart: As the leader of both the Cheer Team and the Culture Festival Committee, she serves to bridge the tension between most of the members and the more unliked Ishigami and Iino respectively.
I Don't Want to Ruin Our Friendship: This is the reason why she's so hesitant to give Ishigami a definitive answer when he unknowingly confesses to her. She isn't really sure if she's romantically attracted to him (along with other issues like the fact that she's going to be graduating soon), but she knows that turning down such a heartfelt confession would break his heart and destroy their already existing relationship. Her attempts to ask Kaguya for advice don't really help due to a case of One Dialogue, Two Conversations.
Important Haircut: She stopped wearing her hair ribbon and cut her hair to chin length (save for the sidelocks) after graduation. Ishigami describes it as making her look more grown up.
Informed Attractiveness: As Tsubame's name is clearly a reference to one of Princess Kaguya's impossible tasks, she is one of the four "Impossible Girls" in school, the four most beautiful women of Shuchi'in High (excluding the student council members) that are impossible to date. She is even referred to as "the Madonna of the third years".
Insecure Love Interest: Unlike previous confessions, she takes Ishigami's very seriously, since he earnestly has feelings for her. However, she isn't ready to commit to a serious relationship (due to how the relationship with her previous boyfriend ended), which is why she rejects his confession on Christmas Eve. She ends up hurting Ishigami because despite not reciprocating, she offers to have sex with him out of sympathy. Chapter 191 elaborates on that, where she admits that while she does love Ishigami, she cannot clearly distinguish between platonic and romantic love. Tsubame wants to act responsible, since she's the elder one in the relationship, but her friends are not helping at all, forcing her to ask a stranger (Shirogane's father) for advice.
Like Brother and Sister: She and Kazeno are close friends, though their relationship is completely platonic.
Long-Distance Relationship: Defied. The reason why she ultimately turns down Ishigami after the Christmas party is because she's graduating and going away to college in three months. She doesn't feel that such a relationship would work out in the long run. It's worth pointing out that she is lying about this and just using it as a cover for her Commitment Issues (since the college is less than half an hour away by train, and she already told Kaguya before that such an excuse would just sound like a roundabout way to tell him that she doesn't like him romantically).
Love Makes You Dumb: Played with. Her grades take a massive hit at the end of senior year (dropping from 7th to 36th) with the implication being that it's from the stress of dealing with Ishigami's crush on her and the looming date of her answer to his confession.
Maybe Ever After: Her live-action counterpart retains her role as love interest for Ishigami, and with Iino's heavy demoting is the only love interest for him in the second movie. They don't exactly get together, but ship tease is heavy and they have a Dance of Romance at the school festival.
Ms. Exposition: She explains to Kaguya the legend and theme of the Devoted Hearts Festival and how High-School Sweethearts can be granted eternal love during the festival, like what happened with her older brother and sister-in-law.
My God, What Have I Done?: At the end of the Christmas party, she immediately regrets offering Pity Sex after Ishigami properly confessed and asked her to date him. Disappointed and irritated, he leaves, at which point she realizes that she just seriously hurt his feelings.
Nice Girl: She's a very kind, pleasant, and selfless girl who likes to help others, is caring and open-hearted, and accepted Ishigami easily into the team despite the rumors surrounding him, which is why he starts falling for her. She also helped both Osaragi and Momo in the past, thought the details for the latter have yet to be revealed.
Nightmare Fetishist: She's apparently a fan of horror stuff, and gets really excited when Ishigami invites her to try out his class's haunted house at the culture festival.
No Sparks: This is ultimately the reason why she turns down Ishigami's Love Confession. Despite how much she may like him as a friend, she just doesn't have any romantic feelings for him.
Not So Above It All: Tsubame is normally a nice and understanding girl, but hilariously enough, just like everyone else, she tells Kazeno off for jumping over a railing while wearing a skirt - which caused him to sprain his ankle right before a relay event - by calling him a moron for it.
Oblivious to Love: Tsubame doesn't realize that Ishigami has a serious crush on her. After he confesses to her, she doesn't know whether she likes him platonically or romantically, because she can't distinguish them. Her friends aren't any help at all, as one of them doesn't have any experience either, and the other one suggests sleeping with him, which she tries to do. Not only did it not help Tsubame find her answer, but she also ended up hurting Ishigami.
Passionate Sports Girl: She's a member of the school's rhythmic gymnastics club.
Promoted to Love Interest: She already was one, but she becomes Ishigami's only love interest and the more pronounced option for him in the live-action version since Iino has been Demoted to Extra. The second movie ends with him giving her the heart pendant, and he dances with her at the bonfire.
Put on a Bus: While she does get a few mentions here and there, she's pretty much gone from the story after graduating.
Retail Therapy: Papa Shirogane describes her as the type who goes impulse shopping while under stress and telling her fortune. This comes up at least twice, both times involving her relationship with Ishigami.
Romantic False Lead: Played with. Tsubame eventually comes to welcome Ishigami's attempts to court her in spite of her own insecurities. This causes Iino to become jealous of them and their date is what leads her to realize her own feelings for Ishigami.
Rose-Haired Sweetie: She has pinkish hair with matching eyes, signifying her good and cheery nature.
School Idol: Erika refers to her as "The Swan of the Third-Years", putting her on equal standing with the likes of Kaguya (which is high praise indeed, given that it's coming from Erika).
Shadow Archetype:
- She serves as one to Kyoko Otomo, the girl Ishigami protected by keeping quiet about the fact that her boyfriend, Ogino, cheated on her, if the rumors about Tsubame's ex-boyfriend cheating on her are true. Tsubame was left scarred and has developed commitment issues, while Otomo has retained her happiness and smile.
- As Chapter 192 reveals, she also serves as an inverted one to Osaragi, both being one of the beautiful "Impossible Girls" in school, but unlike Osaragi, Tsubame is The Social Expert, who was able to withstand the jealousy of others and remained cheerful, while Osaragi became more introverted and cynical.
Sibling Yin-Yang: Romantically, she's the opposite of her older brother. Both of them were confessed to with a heart during the Devoted Hearts Festival, but while he ended up Happily Married to the girl that confessed to him, she spent several months agonizing over how to avoid breaking Ishigami's heart because she didn't feel anything romantic towards him at all.
So Beautiful, It's a Curse: The bonus page in Volume 21 revealed that due to Tsubame's natural beauty, she was the target of a stalker, molester, and has even entered an abusive relationship at one point where she was only in a relationship for a particular person for his social status. In fact, she's so used to boys only being interested in her for her looks that she's completely caught off guard when Ishigami rejects her offer for Pity Sex because he wanted an actual relationship.
The Social Expert: Tsubame is chosen as both the vice-captain of the Cheer Team and the chairwoman of the Culture Festival Committee, because she is able to unite and lift the atmosphere when things get tense. She also advised Osaragi in middle school on how to deal with jealous girls who envy them for their looks and achievements, which earned her Osaragi's Undying Loyalty.
Super Gullible: Tsubame is a bit superstitious, and often asks people for advice, generally believing everything they say. Shirogane's father gives her relationship advice during winter break, only to subvert the seriousness of his words by offering her a phony trinket that would help her, which she immediately buys, causing him to call her out on her gullibility. Its Played for Drama later on, as she heeded Atenbou's advice on having Pity Sex with Ishigami after rejecting his confession, leading to the incident that broke Iino's arm and further complicated a Love Triangle between the three. At the very end of Chapter 191, she still seeks Papa Shirogane's advice when assuming that he still worked as a fortune teller, hinting that she hadn't learned her lesson even after Maki in Chapter 162 indirectly pointed out her naivety in believing fortune tellers.
The Tease: Tsubame teaches Ishigami how to use a cocktail shaker during the Christmas party with a Hands-On Approach that was far more intimate than necessary. She also comes to his room very lightly dressed, sits suggestively, and touches him a lot. She does this all deliberately, given the fact that she knew about his crush on her and was planning on having Pity Sex with him, to figure out how she feels about a romantic relationship with him. She stops this after he rejects her offer.
Tender Tears: The other members of the cheer squad note that she's a crybaby, as shown by her getting emotional over Ishigami getting second place in the relay race.
Theme Naming: She's one of the many people named after Kaguya-hime's impossible tasks. In particular, she takes her name from Isonokami no Maro (Ishigami's namesake)'s task item, the swallow's cowry (tsubame no un da koyasugai).
Unknown Rival: Iino admit she hates Tsubame for this, even if she was always friendly. But Tsubame apparently had no idea another girl loved Ishigami.
Unwitting Instigator of Doom: In Chapter 120, Tsubame tells Kaguya about heart-shaped gifts during the cultural festival, which would grant the couple eternal love. She gifts Kaguya one of the heart trinkets they are selling as a service, but Kaguya loses it and it's found by Ishigami, who gives it to Iino, so she can put it in the lost & found box of the disciplinary committee. Ishigami giving Iino the trinket is part of the reason why Iino starts to view Ishigami in a different light, setting in motion the love triangle between her, Ishigami, and Tsubame.
We Used to Be Friends: Has a massive fight with Otomo, her kouhai from middle school, when she learns what really happened between her and Ishigami. To her, the Ishigami Otomo was describing didn't sound anything like the Ishigami she got to know personally, and was greatly saddened to see him be so hated by someone he wanted to help.
Your Approval Fills Me with Shame: In chapter 192 when Tsubame reveals her plan to reveal at least some of the truth of Ishigami's actions to Otomo to both Kaguya and Osaragi. Kaguya is shocked but approves, saying that even she couldn't come up with and do Tsubame's plan, much to Tsubame's displeasure.

Terashima "Terako/Gigako/Megako"

Voiced by: Rina Honnizumi (Japanese), Lisette Monique Diaz (English)

Debut: Chapter 29 (Manga), Episode 13 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/gigako.png

The oldest member of the Tabletop Games Club with constantly changing nicknames.

Adaptation Dye-Job: She has black hair and gray eyes in the manga. The anime changed both of them to brown.
Adaptational Late Appearance: The anime cuts out her initial cameo from Chapter 29, so she doesn't appear until the adaptation of Chapter 57 at the beginning of Season 2.
Book Dumb: She ranks near the very bottom of the senior class on exams, and her constantly decreasing nicknames suggest that she isn't much better at games. Chapter 202 reveals that she had already failed her senior year once, and she only managed to pass the second time around because her grandfather pulled some strings.
But Not Too Foreign: As the principal's granddaughter, she's part-French.
Chekhov's Gunman: Is first introduced as just another member of the Tabletop Games Club Fujiwara is part of before later chapters revealed her to be the headmaster's granddaughter. She's also the one who allows Ishigami to befriend Shiranui. Later still, Fujiwara and Iino threaten to expose Seiryu's deviancy to the media during the final arc. This doesn't intimidate Seiryu, as the Shinomiya family has a tight grip on the press. But they can't silence Megako, who has a not-so-insignificant social media presence by this point.
Connected All Along: She's the principal's granddaughter.
Constantly Changing Name: As the series goes on, her nickname changes to smaller and smaller metric prefixes.
The Dreaded: The Mass Media Club duo refer to the Tabletop Games Club as a "den of evil".
For Happiness: Her personal view of games (both digital and analog) is that they're something that's supposed to bring people joy, both as individuals and as a group. It's the entire reason she founded the Tabletop Games Club.
Gamer Chick: She's a member of the Tabletop Games Club, and becomes a professional e-sports player after graduation.
Genius Ditz: She gets terrible grades and her board gaming skills aren't implied to be any better, yet she's pretty much unbeatable when it comes to competitive FPSs.
Meaningful Rename: She used to be called "Terako", but she got demoted to "Gigako" after losing a game. The Volume 11 extras reveal that she was further demoted to "Megako".
Motive Misidentification: Downplayed. She thinks that the reason why Fujiwara keeps on having the Student Council play games is because she wants everyone to have fun together. While that's certainly part of it, her habit of cheating and Sore Loser tendencies make it clear that she's more concerned with winning to feed her ego.
Nice Girl: All signs point to her being a much more benevolent person than her clubmates. Despite being a well-known streamer and e-sports player by Chapter 228, she still makes time to play a few rounds with Ishigami simply because he's Fujiwara's friend.
Only Known By Her Nickname: She's only referred to in-series by her ever-decreasing nicknames. It isn't until Chapter 202 that she's referred to by name (and even then, only her surname).
Otaku: She is a "mega otaku" according to Fujiwara. If the figurines in her bedroom are any indication, she's specifically a fan of the Super Robot Genre.
Put on a Bus: Subverted. While all of her fellow third years disappear from the narrative following graduation, she only becomes relevant to the plot after that point.
Secret-Keeper: As one of Shuchi'in High's most influential students, she is aware of Ko Ogino's true character.
Shared Family Quirks: Both she and her grandfather are fans of Pokémon GO.
SI Prefix Name: Terashima is originally nicknamed "Terako", but then got demoted to "Gigako", and later "Megako".
Still Wearing the Old Colors: Downplayed. Her Winecraft skin in Chapter 270 is wearing the Schuchi'in school uniform even though she graduated several months prior. For bonus points, the skins of the two people she was playing with (both of which are current students) are wearing regular clothing and the chapter takes place over summer vacation when no one would be wearing their uniforms anyway.
Sweet Tooth: According to Chapter 171, she always has cookies in her bag.
Those Two Guys: Rarely seen without Makki-senhai.

Previous Student Council President

Voiced by: Nobunaga Shimazaki

Debut: Chapter 121 (Manga), Episode 17 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/past_president.png

Shirogane's predecessor on the student council who had originally recruited him to be the General Affairs officer.

Commissar Cap: He wears one as part of his student council uniform, which helps to give him an air of authority.
Early-Bird Cameo: He shows up early in the anime when Fujiwara is leading the student assembly in singing the school anthem during Episode 17 (he's the one all the way in the bottom right wearing a hat).
Everyone Calls Him "Barkeep": Much like with his successor, he's only ever referred to by his title. Unlike with Shirogane though, his real name has yet to be revealed.
Exotic Eye Designs: For whatever reason, his eyes are drawn without pupils.
Nice Guy: While very little is seen about his personality, he was the first person in the school to reach out to Shirogane. He's also the one who established the practice of allowing normal students to come into the student council room to ask for help with their problems.
No Name Given: Has yet to be given a name in official material.
Small Role, Big Impact: He only shows up in three chapters (plus an Early-Bird Cameo in the anime), yet both of the series' longest-running plotlines can be traced back to him. Shirogane never would have fallen in love with Kaguya if he hadn't reached out to him and taken him to the lake on that fateful day, and Tsubasa never would have confessed to Kashiwagi if he hadn't established the practice of allowing students to seek advice from the student council.
Student Council President: He held the role before Shirogane.

Class 3-B

Kazeno

Voiced by: Taishi Murata (Japanese), Daman Mills (English)

Debut: Chapter 82 (Manga), Episode 17 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/kazeno_1.png

An upperclassman and captain of the Cheer Team.

Chick Magnet: Quite a few girls were pretty excited to see him crossdress in the sports festival.
Ditzy Genius: He gets very good grades (being ranked 4th among the senior class), but he was dumb enough to try and jump a railing while wearing a long skirt, hurting his leg in the process.
Early-Bird Cameo: He shows up early in the anime when Fujiwara is leading the student assembly in singing the school anthem during Episode 17 (he's the really tall one in the fifth row).
The Faceless: As with the rest of the cheer team, in the sports festival arc. He only gets his face properly shown after Ishigami "opens his eyes" to the world again.
Heroic BSoD: The break-up with Osaragi depresses him greatly, though he manages to cope with it by devoting his feelings to idols.
Keet: He's the captain of the Cheer Team, it's to be expected.
Like Brother and Sister: Ishigami assumed that he was in a relationship with Tsubame due to them having been friends for so long, though this is shot down when it's revealed that he's actually dating Osaragi.
Lovable Jock: It isn't known if he's on any sports teams, but he is really into working out and is an all-around Nice Guy.
Nice Guy: Much like Tsubame, he accepts Ishigami easily despite the rumors surrounding him.
No Full Name Given: He's only ever referred to by his first name. Even the volume extras showing the end-of-semester rankings list him as "Captain Kazeno".
One Head Taller: His girlfriend Osaragi is a little less than a head shorter than him. Of course, she is roughly two years his junior.
On the Rebound: He immediately jumps into an otaku "relationship" with idols after Osaragi dumps him. Seeing as Osaragi is as beautiful as these idols, and in fact was an idol in the past, it's clear he is projecting.
Kazeno: All the love I'd meant to give her, I've been pouring into these girls instead.
Otaku: He ends up becoming an Idol otaku to cope with his depression over Osaragi breaking up with him.
Put on a Bus: He's last seen leaving the school after graduating and is never directly mentioned again (discouting Ishigami referring to the Cheer Team as a whole), though some dialogue does allude to him and Ishigami still hanging out from time to time.
Wholesome Crossdresser: Not usually (as far as we know), but he is the one who came up with the idea for the Cheer Team to cross-dress during the sports festival.

Unknown Class

Shizuku Asahi

Debut: Chapter 121 (Manga), Episode 33 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/shizuku_2.png

An upperclassman and also the president of the Mass Media Club, who works as the chief editor of the school newspaper.

Adaptational Late Appearance: Downplayed. The anime has her introductory flashback take place right after the culture festival starts as opposed to right before it.
Ascended Extra: She has a grand total of two proper appearances in the main series before graduating, but she is a supporting character in We Want to Talk About Kaguya due to her being in the same club as Karen and Erika.
Beleaguered Boss: As Karen and Erika's immediate superior in the Mass Media Club, she has to frequently keep both girls focused on their job while pulling them back to reality every time they're in Kaguya fangirling mode again. Which happens nearly all the time.
Character Witness: While talking to Tsubame in Chapter 191 about Ishigami, she mentions that both Karen and Erika trust him.
The Confidant: Chapter 191 shows her listening to Tsubame's romantic issues. She can't really offer any kind of advice, though, since she has no experience in love. However, she was wise enough to warn against Atenbo's "when in doubt, have sex" suggestion and testifies that Karen and Erika both trust Ishigami. This doesn't help Tsubame's dilemma, and Asahi ends up telling her friend how annoying she is.
Deadpan Snarker: Being directly in charge of two of the biggest and nuttiest Kaguya fanatics will turn you into one.
Given Name Reveal: It took 70 chapters for her name to be revealed.
Hidden Depths: The shots of her bedroom that we see in Chapter 200 imply that she's either really into art or paints in her free time, as she has multiple pictures in a variety of styles hanging on her wall (one minimalist and one cubist from what is visible).
Hypocrite: She scolds Karen and Erika for their favorable bias towards Shirogane in the election when they're supposed to be impartial as journalists. This is despite the fact that Kaguya had already arranged for her to support his reelection campaign.
I Owe You My Life: After saving her from drowning in a flashback, Kaguya mentioned to Hayasaka that owing her a favor may prove useful in the future. We Want to Talk About Kaguya implies that she cashed in that favor to insure the Mass Media Club's support in Shirogane's reelection.
It Runs in the Family: Her father is the chief of a big newspaper company.
Meaningful Name: Her surname 'Asahi' (朝日) refers to the real-life newspaper Asahi Shimbun, one of the five largest newspapers in Japan.
Not So Above It All: Though she frequently chastises Karen and Erika for their borderline fanatical worship of Kaguya, she indirectly admits and considers herself "more than just a fangirl" for Kaguya, but refuses to give any more details to Karen and Erika beyond that out of combination of embarrassment and not wanting to associate herself with their loonier fangirling. In her case, it's understandable: Kaguya did save her life.
Only Sane Woman: Compared to Karen and Erika, she's the only named member of the Mass Media Club that actually focuses on doing her job. She also blocks all of their student council-centric articles from being published, since they write about as obsessively as they talk. Then again, she also appointed them as the new leaders of the Mass Media Club when she graduated.
Prophetic Name: Her first name translates to "droplet" and her last name means "morning sun", alluding to how her falling into a swamp marked the start of Kaguya and Shirogane's romance.
Secret-Keeper: As one of Shuchi'in High's most influential students, she is aware of Ko Ogino's true character.
Small Role, Big Impact: The only thing of consequence she ever does in the series before she graduates is falling into a swamp, but she has a major effect on the overall plot due to Kaguya rescuing her being the reason Shirogane fell in love in the first place.

Yume Atenbo

Voiced by: Ai Kakuma (Japanese), Brittney Karbowski (English)

Debut: Chapter 39 (Manga), Episode 8 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/yume_7.png

The granddaughter of a high-ranking priest and president of Shuchi'in High's Occult Research Club.

The Blind Leading the Blind: Atenbo is the one Tsubame listens to regarding her relationship with Ishigami, which ends up with Tsubame trying to initiate Pity Sex with him. Asahi criticizes her for the ill advice she gave, despite never being able to keep a longer-lasting relationship, yet Atenbo still thinks her advice was sound.
The Confidant: She is seen in Chapter 191, along with Asahi, listening to Tsubame's problems and advising her on how to proceed. Unfortunately, her advice doesn't help Tsubame at all.
Early-Bird Cameo: She is first introduced in Chapter 39 as one of the club presidents who have the power to send any student and their family packing if they misbehave. However, her first real appearance is in Chapter 131, near the end of the Culture Festival arc.
Ethical Slut: Based on the relationship advice she keeps giving to others, it's clear she is someone who thinks Sex Is Good and helps them sort their feelings out.
Expy: Her name, occupation, and art design are clearly based on "The Witch" (Yume Furusana), a character from Akasaka's previous manga ib: Instant Bullet.
Eyes Always Shut: Her eyes have never been seen open, which fits her laid-back and mischievous personality.
Fortune Teller: She is seen during the last day of the culture festival, where she tells Kaguya's and Shirogane's fortunes. It's not clear if she really can see something or if she is just making good guesses.
The Gadfly: Couples who ask her for their fortunes are getting teased so much that it borders on sexual harassment. For instance, when Kaguya and Shirogane come into her room, she assumes that they have a Secret Relationship and asks if they are using proper protection. She also frequently brings up people's libido and how they need to deal with it.
Meaningful Name: Her given name is written in hiragana, giving a lot of ways to interpret it. "Yume" (夢) for instance can mean "dream".
Nightmare Fetishist: She is the head of the Occult Research Club, so that was a given. Chapter 194 reveals that Kaguya received the recipe for the previous Valentine's Day Cubari Facaccimo "chocolate" from her. The shots of her bedroom that we see during Tsubame's group chat also include things like crystal balls, black drapes, and a (hopefully fake) human skull.
Preacher's Kid: Well, grandkid (as her grandfather is a Shinto priest). She fits into the naughty catagory as she's both an Ethical Slut and known for giving advice that borders on sexual harassment (in addition to an interest in the occult).
Secret-Keeper: As one of Shuchi'in High's most influential students, she is aware of Ko Ogino's true character.
Small Role, Big Impact: Chapter 191 reveals that she was the one who told Tsubame to sleep with Ishigami, so she can be certain of her feelings for him. What she didn't expect was that Ishigami is an idealistic romantic who isn't just out for sex like that (and especially doesn't want to be pitied), which not only didn't help Tsubame, but made things worse between her and Ishigami, and indirectly led to Iino's arm being broken.
Stalker without a Crush: She somehow has access to information that shouldn't be publicly available, like Shirogane's weight at birth.
Unwitting Instigator of Doom: She was the one who suggested that Tsubame offer Pity Sex to Ishigami during her Christmas party, and thus is indirectly responsible for Iino breaking her arm and complicating the love triangle between Ishigami, Iino, and Tsubame.
You Need to Get Laid: Her relationship "advice" to others boils down to "have sex". It backfires horribly when she suggested the same to Tsubame to help her figure out her feelings for Ishigami. Ishigami isn't interested in sex without love, and Tsubame is too indecisive, so rejecting his confession yet still offering Pity Sex ended up hurting both Tsubame and Ishigami.

Shuchi'in Academy Middle School

Student Council

Kei Shirogane

Voiced by: Sayumi Suzushiro (Japanese), Heather Walker (English), Nathalia Guillen (Brazilian Portuguese)
Played by: Amu Fukao (live-action movie)

Debut: Chapter 28 (Manga), Episode 6 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/kei_shirogane.jpg

Miyuki's younger sister. Treasurer of the Shuchi'in Academy Middle School Student Council.

Adaptation Dye-Job: The live-action movie gave her black hair.
Adaptation Relationship Overhaul: In the gender-bent AU chapters of the Official Doujin, she's notably much closer and less rebellious to Miyuki, who's her older sister there, even referring to her as "Nee-san".
Annoying Younger Sibling: Kei is generally nice and polite, but is fairly rude towards her brother in comparison. Later revealed to be part of her rebel phase, since she feels like she's treated like a child whenever Miyuki interacts with her. This can also be seen in the way she calls her brother. She refers to Miyuki simply as "Onii", without -san, -chan, or any other suffix, showing that she acknowledges him as her brother but doesn't show him any additional respect beyond that.
Big Brother Attraction: Defied. She deliberately avoids actions that would make her look like a brocon, and tends to complain at length about him given half a chance. This actually backfires in Moeha's case, as there's a noticeable undertone of pride in Kei's complaints that led her best friend to develop a Love Before First Sight on Miyuki.
Big Brother Worship: Double Subverted. Kei greatly admires her older brother, but she deliberately hides it due to a combination of being in her rebel phase and not wanting people to think she has a brother complex. Even then, her pride for him still pours through in a Tsundere manner, enough so that Moeha falls in love with him based solely on her stories.
- Kei greatly admires Kaguya even though they aren't blood-related, seeing her as a big sister figure. Kaguya's later interactions with her prove that this feeling is clearly mutual.
Bratty Teenage Daughter: Downplayed but present in her interactions with her father and older brother. Interestingly, her teenage "rebellious phase" is more prevalent with the latter, probably because her brother persists in acting somewhat like a parental figure to her despite the verbal abuse he gets for it, unlike their father who seems to have given up completely.
Brutal Honesty: Which is why her brother's unwillingness to just say outright what he feels annoys her.
Calling the Old Man Out: In Chapter 272, she calls her mother out after the latter claims that Miyuki's grades improving justifies her decision to abandon the family and take Kei with her.
Kei: Mom... we don't need to be geniuses. What we really needed in our lives were neither good grades nor a perfect future. All we really wanted was a normal, loving mother.
Character Tics: She pretends to be stretching whenever she's secretly listening in on whatever her brother is doing.
Chekhov's Gunman: Miyuki mentions her in the first chapter and she gets a few other acknowledgments early on, but she doesn't actually make a proper appearance until Chapter 39.
Deadpan Snarker: When she's not outright insulting and arguing with her family, she comments on everything with a snide remark.
Kei: (after Miyuki was gifted with his father's moon watch) Wow, it smells like old man in here.
Don't Split Us Up: Her mother initially took custody of her when she abandoned their father due to her being more successful in her studies than her brother. However, she soon chose to go back to her father and brother, and doesn't seem to have a high opinion of the woman in the present.
Ensemble Dark Horse: In-universe. She's very popular among the fans of her father's YouTube streams and it always sees a spike in donations when she's on-screen.
Even the Girls Want Her: It's mentioned that she is popular even among girls.
Everyone Has Standards: The fact that she loves her brother does not mean that she has the patience for most of the stuff he does. However, whenever he is not near, she won't hesitate in talking about him with nothing but praises (just expressed in a Tsundere manner).
Favors for the Sexy: Kei finds herself on the receiving end of this after her father becomes a successful YouTuber, with people throwing down 10000 yen in the super-chat every time she walks across the screen during one of his live streams.
First-Name Basis: Insists on Kaguya calling her by her first name, which is something Kaguya usually never does, not even with Hayasaka.
Gender-Blender Name: Just like her older brother.
Good with Numbers: Implied, given that she is the treasurer for the middle school student council and in charge of her family's finances.
Hairstyle Inertia: Flashbacks show her having the exact same hairstyle as a child, just shorter and with a hairband instead of a ribbon.
Hereditary Hairstyle: The ribbon she wears is the only thing that separates her hairstyle from her mother's.
Hot-Blooded: She is markedly snappy when it comes to her brother, venting her teenage angst upon him in her mother's absence.
Interclass Friendship: With Moeha, and through her with Fujiwara. Later with Kaguya.
Irony: Her constant complaining about her brother made her best friend develop a crush on him before even meeting him in person. Specifically, the underlying tone of pride in her complaints gave Moeha an extremely positive image of him, an image that was (accidentally) reinforced when she actually met him in Chapter 126.
It Runs in the Family: She has the same piercing glare as her brother and is just as good at hiding her shyness. The narrative also lampshades that her nervousness around Kaguya is a result of siblings having similar tastes. Chapter 52 reveals that she's just as thrifty as him, just as kind, and enjoys coffee.
I Want My Beloved to Be Fashionable: Non-romantic example. In Chapter 119, Kei goes out of her way to make sure Miyuki doesn't embarrass her at her school festival, either by standing out in his high school uniform or by looking like a middle schooler with his terrible fashion sense. Seeing how her classmates are smitten and impressed by Miyuki when he shows up, she can't help but smile blissfully.
Jerkass Has a Point: While she is saying it because she doesn't want her image of Kaguya being "deflowered" by Shirogane, Kei has a good point in that their rooms are close to each other and she could hear anything if they do something due to the thin walls.
Jerkass to One: She's a lot harsher towards her brother (and to a lesser extent, her father) than everyone else. This is mostly a result of her venting all her frustrations towards her absent mother on them.
Locked Out of the Loop: While she knows that her brother has a crush on a girl, she has no idea that the girl in question is Kaguya (instead, she thinks that it's either Fujiwara or Hayasaka). She doesn't find out until Chapter 170, when she hears the two of them flirting over the phone for almost 5 1/2 hours. Additionally, she had no idea that the pair already had Their First Time when she starts preventing the two from acting like a couple.
Missing Mom: Her mother ran off about seven years before the story began.
Moment Killer: Despite actually wanting them to eventually get married, Kei hates the idea of her brother defiling Kaguya (unaware that the two have already had sex) and does everything she can to keep them separated when Kaguya comes to visit in Chapter 236.
Mundane Luxury: When her father announces that they're going to be moving into a new apartment, the thing she gets most excited about is that she'll get to have her own room rather than have to share one with her brother.
Nice Girl: Despite her rebellious streak towards her brother (she's an adolescent after all), she's just like him; a very nice and kind-hearted person, and very selfless. It's later revealed that she was angry at him for giving her birthday money despite a "no presents" agreement they made due to their impoverished living situation.
Not Blood Siblings: While she averts this in the series proper (being Miyuki's biological sibling who has zero romantic or sexual feelings for him), the "Miyuki and His Girls" bonus chapter has her playing this role completely straight.
Not So Stoic: While she's normally very cool-headed and collected, like her older brother, she's also occasionally shown to be Not So Above It All on the inside, also like her older brother. The most notable example is probably when Miyuki walked out wearing his Impossibly Tacky Clothes and she melted down ranting about them.
Odd Friendship: She's somehow best friends with Moeha, of all people. How something like that came about is never really explained.
One Degree of Separation: She is in the same year as and friends with Fujiwara's younger sister Moeha. She sleeps over frequently at the Fujiwara household, and as a result, is also close friends with Fujiwara herself.
Perpetual Poverty: Due to her father being deep in debt, Kei constantly struggles with money and thinks in newspaper deliveries she has to do when she wants to buy something. This isn't likely to change in the near future, since her father cannot keep a job for long and both she and her brother are still in school. And while her father seems to have a promising future as a YouTube celebrity, if he really has built up a debt of over 500 million yen, he won't be able to pay off everything for a long time.
Practically Different Generations: While the two of them are just shy of being 3 years apart in canon (her birthday's in August and his is in September), the Kindergarten AU chapters of the Official Doujin ages her down to around 4 while Miyuki is an adult.
The Quiet One: Her focus chapter states that she doesn't speak a lot.
The Runaway: Subverted. She ran away from her mother to be with her father and brother, partially out of guilt for abandoning them, and partially because she didn't feel comfortable sharing a home with her mother's boyfriend.
School Idol: Just like her brother, Kei is admired by both the boys and girls in her school for her cute looks, her grades, and her innocent and just personality.
Secret-Keeper: She finds out about her brother and Kaguya dating after overhearing them having a 5 1/2 hour phone call and then not long afterwards begins pumping him for all the juicy details.
Sell-Out: Chapter 191 shows that she is seriously contemplating to sell herself out on the internet, seeing as her father gets 10,000 yen donations whenever she is passing by while he streams, with her admitting that she has done it on purpose several times already.
Shipper with an Agenda: While pairing her brother with Kaguya does seem genuine on her part, she also sees this as an opportunity to get closer to Kaguya as a sister-in-law. Humorously, while she wants them to be a couple, she doesn't want them actually acting like one because she hates the idea of her brother defiling someone she admires (ironically she remains unaware that they already had Their First Time). As such, she does everything she can to get between them when Kaguya comes to visit.
Siblings Wanted: Kaguya is jealous of Fujiwara's friendship with Kei, not knowing that she herself has the potential to be Kei's family, which is considerably more poignant than anything Fujiwara has with Kei, and even more, that Kei longs to be Kaguya's family too. She is in sore need of a stable female influence in her life, which her female friends in the Fujiwara family don't actually fulfill; cue Kaguya, a person she admires and wants in her life. The main reason she wants Kaguya to marry her brother is so they could be a family.
Sibling Triangle: Subverted, because Kei isn't actually romantically interested in Kaguya, unlike her brother. However, both vie for Kaguya's affection and smugly tell the other sibling how close they are to Kaguya. Miyuki shocks Kei though, when she learns in Chapter 170 that the two have become a couple, and it is immediately clear afterwards that she wants to learn all the details.
So Proud of You: Beneath all her bitching and moaning regarding her brother lies a girl that has nothing but pride and love for him.
Strong Family Resemblance: She looks like a female version of her brother, right down to the eyes. The resemblance is strong enough that Kaguya instinctively shows attraction to her despite her otherwise Single-Target Sexuality. Kei also has inherited her mother's looks, looking like a younger version of her.
- The gender-bent AU of the Official Doujin gives Kei a slightly different facial design where she looks like a younger version of Miyuki, who was born as a girl there.
Token Mini-Moe: She's a middle schooler and extremely adorable. Even Kaguya instinctively calls her cute as soon as she meets her, though given how she is, it also could be her similarities to her brother in appearances that prompted the reaction.
Too Much Alike: Kei, like her brother, is a prideful tsundere who Cannot Spit It Out. Thus she can't stand him always telling her what to do but she can't bring up the nerve to speak to him normally thus leading to their current frosty relationship.
Tsundere: She's a (platonic) Harsh tsundere for her own brother. His nagging, pseudo-parental attitude gets on her nerves and she lashes out, to the point where the two of them haven't had a normal conversation in years. Despite that, she does care about Miyuki (and is shown to be very proud of him), but carefully measures her interactions with him so it doesn't look like she has a brother complex.
Unwanted Assistance: Her attempt to cover for Miyuki when Kaguya comes over to visit ends up making things look even worse than they would have originally, thanks to her tossing bags of trash and an erotic magazine into his study room. To make things worse, when Kaguya spots the magazine, a pair of Kei's panties are sitting right on top of it. Needless to say, this absolutely mortifies her.
Vicious Cycle: The narration outright describes her relationship with Miyuki as one of these. His overprotective attitude makes her feel like he still sees her as a child, which leads to her acting mean and distant to him, which only makes him nag her more.
What Beautiful Eyes!: Kaguya comments on the fact that she has the same eyes as her older brother upon meeting her for the first time, and nearly squees in excitement when she realizes the resemblance.

Moeha Fujiwara

Voiced by: Ari Ozawa (Japanese), Kara Edwards (English), Nica Nogueira (Brazilian Portuguese)

Debut: Chapter 39 (Manga), Episode 8 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/moeha.png

Fujiwara's younger sister and the vice-president of the Shuchi'in Academy Middle School Student Council. She is close friends with Kei, who as a result frequently sleeps over at the Fujiwara household.

Adaptation Dye-Job: Like her older sisters, her hair was changed from silver to pink in the anime.
Buxom Beauty Standard: Just like her sisters, she has a well-endowed figure for her age, which Kaguya bitterly notes by sending a Death Glare towards them.
Commonality Connection: For all of Kaguya's comments about being unable to deal with her, they do have one major thing in common: their taste in men. They end up having a bonding experience over this commonality.
Cute and Psycho: Her introductory chapter has her talking about wanting to torture Kei and eat Kaguya, all with a smile on her face. Later on, even the narrator will remark that she's a bit of a psychopath.
Dating What Daddy Hates: Her sister Chika is extremely disapproving of her crush on Shirogane.
Foil: For Kaguya. Both of them are vice-presidents of their respective student councils, the youngest members of their families, and have a crush on Shirogane, but their personalities are complete opposites; Kaguya is scary on the outside and sweet on the inside, while Moeha is sweet on the outside and scary on the inside.
Girlish Pigtails: As befitting her Cute and Psycho personality, she wears her hair in two tails.
Hopeless Suitor: She doesn't really have any chance of getting together with Shirogane, given that he is solely focused on Kaguya by the time her crush is revealed. She's still pining over him by the time of Kei's epilogue chapter, even though he and Kaguya have been openly dating for months at that point.
Interclass Friendship: She's best friends with Kei, whose family is working class.
Jerkass Has a Point: Downplayed as she isn't being a jerk about it, but when Chika brings up several of Shirogane's bad qualities but quickly adds that he fixes them, Moeha doesn't see the issue. According to Moeha, what Chika is saying sounds like Shirogane is the type of guy who wants and can improve himself rather than being a lazy broken mess.
Love Before First Sight: She fell in love with Shirogane based solely on Kei bragging/complaining about him.
Odd Friendship: By all appearances, she doesn't seem like the type of person that Kei would hang out with, yet they're somehow best friends.
Precocious Crush: She's three years younger than her crush Shirogane. Kaguya even brushes her off as a threat for this very reason... at least until they end up bonding over it.

Third-Years

Hifumi Abe

Debut: Chapter 211 (Manga)

A member of the Abe family and Gomanosuke's owner.

Feet-First Introduction: The first time we see him is of his shoes, with his cat being the one in focus.
Prophetic Name: He's named after Kaguya-hime's final suitor, which marks him as both the most obvious pick to fill in the vacant seat in the student council and having some sort of relationship with his Impossible Girl counterpart Shiranui. Except not really. Outside of his Feet-First Introduction, he's only mentioned in a single line of dialogue as Gomanosuke's owner and then disappears from the story altogether.
Red Herring: His name makes him seem like he'll be important due to him being named after Kaguya-hime's final suitor, but he never joins the student council and isn't shown to have any sort of relationship with his Impossible Girl counterpart Shiranui.
Walking Spoiler: It's kind of hard to say anything about him outside of his first appearance without spoiling the fact that that's his only appearance.

Mitama Tono

Debut: Chapter 278

A flirtatious girl who was recruited to serve as the 69th student council secretary.

Boxed Crook: Downplayed as no laws have been broken, but the school VIPs decided that the best way to keep Tono from causing chaos in the school was for her to join the student council where Iino could keep an eye on her.
Bunny-Ears Lawyer: Ishigami admits that she's the only one of the new council members that can actually do her job in spite of her eccentricities.
Contrasting Replacement Character: She's the anti-Fujiwara. Both are troublemakers, but have an opposite love life (Fujiwara remains single for the entire story while Tono literally defines her worth by how many boys she can seduce). Ironically, Ishigami (whose rivalry with Fujiwara spanned the entire series) considers Tono the only reliable member of the new council.
Last Episode, New Character: Her only appearance in the manga proper is during Iino and Ishigami's epilogue chapter.
Really Gets Around: Ishigami's inner thoughts don't mince words about her being a loose woman.

Kogane Kanegae

Debut: Chapter 278

A popular TikTok influencer who serves as the auditor on the 69th student council.

Book Dumb: He barely passed his senior year of middle school.
Contrasting Replacement Character: He's basically Kaguya's opposite in every way save for both coming from zaibatsu families. While she was the top of her class yet Hopeless with Tech, he's tech-savvy yet Book Dumb. His parents are also implied to be a lot less controlling than Gan'an was, given that there's no indication of them having any problem with him being genderqueer.
Last Episode, New Character: He's only introduced in Iino and Ishigami's epilogue chapter.
Ninja Pirate Zombie Robot: A rich, genderqueer, (possibly) crossdressing gamer and TikTok Influencer. Ishigami even lampshades how over-the-top his list of qualities is.
The One Guy: He's part of the Tabletop Gaming Club, which had only ever had female members prior to him joining.
Wholesome Crossdresser: Maybe. He identifies as male but wears Shuchi'in's female uniform. It isn't made clear if he's forced to wear it due to being assigned female at birth or if he just prefers it over the male one.

Former Students

Kyoko Otomo

Voiced by: Reina Ueda (Japanese), Brittany Lauda (English), Patt Souza (Brazilian Portuguese)

Debut: Chapter 55 (Manga) Episode 22 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/kyoko_57.png

The girl that ruined Ishigami's reputation in middle school.

Adaptational Jerkass: The anime adds an extra line to her rant against Ishigami where she yells at him for having the audacity to be enjoying himself at the sports festival, feeling he has no right to be happy after what she thinks he did. Oddly enough, in the second season's extra comic strips, they also reveal that Otomo is intentionally trying to make herself still hate him, but she can't completely do it since it's been so long and he looks good in drag.
Adaptational Late Appearance: The anime cut out her cameo during Kaguya and Ishigami's first study session, so she isn't seen until Osaragi's Day in the Limelight when she gives an abridged version of Ishigami's backstory to the audience.
Book Dumb: Turns out the reason she's not in Shuchi'in Academy High School is that she flunked the entrance exam.
The Bus Came Back: She disappears from the plot after the events of the sports festival due to no longer attending the school, only to pop back up 100 chapters later during the "End of Secrets" arc.
The Dreaded: To Ishigami. As soon as she shows up at his first sports festival, his mood deflates and becomes filled with fear.
Early-Bird Cameo: She makes a couple of appearances in flashbacks before her proper physical appearance in the sports festival arc.
Given Name Reveal: Finally gets her name in Chapter 88.
Good All Along: More of a revelation to the audience. All of her flashback scenes made it look like she randomly accused and led the pack on Ishigami for something he didn't do. In reality, she was defending her boyfriend from being punched, who she didn't know was a Bitch in Sheep's Clothing.
Hidden Depths: One of the extra 4komas released with the second season's blu rays reveal that she actually attempted to forgive Ishigami for the incident in middle school as she didn't really want to keep staying mad at him forever, but hilariously enough, her petty jealousy at seeing him having fun with Tsubame made her forget about that.
Innocently Insensitive: Upon reuniting with Ishigami, she wastes no time throwing insult after insult at him over what happened to them in middle school. She is completely unaware of all the circumstances, which Ishigami prefers.
Locked Out of the Loop: Intentionally so. She's kept ignorant of her boyfriend's true colors even after she leaves school, for the sake of her happiness. The main point of Ishigami's martyrdom, and why he rescued her from her boyfriend at the cost of his own reputation, was so that she left the ordeal completely unharmed.
Missed Him by That Much: She was just inches away from being retaliated against by Kaguya, who is dissuaded from doing so by Hayasaka because that would be a disservice to Ishigami's efforts to make Otomo happy. Instead, Kaguya reveals that while she'd keep her hands off Otomo, she had enacted retribution on Otomo's boyfriend for what he did the minute she learned the truth.
Nice Girl: She's actually a rather sweet person and went out of her way to be friendly with Ishigami. The only problem is that she trusted her former boyfriend more than him when she really shouldn't have. Not helping this is that Ishigami would prefer her hating him to her being hurt by the knowledge her boyfriend was cheating on her.
The Not-Love Interest: Ishigami explicitly points out that he was not in love with her, though others like Osaragi don't seem to agree, especially since he fell in love with Tsubame, who is similar to Otomo in several ways.
One-Steve Limit: Averted. Chapter 198 shows another Kyoko on the first-year class rankings.
Shadow Archetype: Inverted with Tsubame. Tsubame is what Otomo could have become if Ishigami hadn't stayed silent and she learned that her boyfriend cheated on her. Tsubame has Commitment Issues, while Otomo was left clueless and, outside of her breaking up with Ogino, has left Shuchi'in with only happy memories.
Took a Level in Jerkass: Becomes this following the incident with Ogino. After Ogino falsely framed Ishigami as the stalker while making himself look like the good guy, she constantly antagonizes Ishigami, even refusing to let go of the past and continues belittling him in the present. Even after Tsubame tries to explain the incident to her, she poured her drink on her after a dispute regarding the past before leaving, showing that she is very stubborn and unwilling to listen to other people.
We Used to Be Friends: It's revealed long after her appearance that she and Tsubame are old friends from middle school. Not so much anymore when Tsubame learns the truth behind the incident between her and Ishigami and comes to his defense, prompting a huge fight between them.
With Friends Like These...: When Ishigami calls her an idiot, her friends comment it was very harsh from him, even if it's true. Yes, in front of her.

Ko Ogino

Voiced by: Kengo Kawanishi (Japanese), Matt Shipman (English)
Played by: Fumiya Takahashi (live-action movie)

Debut: Chapter 85 (Manga) Episode 22 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/ogino.PNG

A former student of Shuchi'in Academy Middle School and Otomo's ex-boyfriend.

Adaptational Villainy: He's already a villain in the manga, but the live-action version get paid to allow boys to rape Otomo in her sleep. And it didn't stop after Ishigami's intervention.
Bitch in Sheep's Clothing: He presents himself as a kindhearted and upstanding student when in reality there is nothing good about him.
Bowdlerise: His cruder remarks about Otomo, which reveal just how disgusting and despicable he really is, when Ishigami confronts him from chapter 88's original release are muted out via Ishigami's monologues covering up his original dialogue in both the tankobon release of Chapter 88 and the anime (which adapts the tankobon's version of the chapter).
Bright Is Not Good: He wears a white-colored Gakuran and has a friendly air presented to everyone, but is definitely not a good guy in the slightest.
Bus Crash: Downplayed. Kaguya tells Hayasaka that she ratted Ogino out to Shuchi'in's club presidents, fully aware that they would not approve and send him away. He was Put on a Bus, and while he's not dead, he's never going to come back.
The Casanova: What he truly is deep down, as the only thing he cares about girls is to satisfy his own carnal desires.
Exact Words: What allows Ishigami to tell that Ogino's cheating on Otomo, besides the shifting of his eyes and tone of voice. When Ishigami asked if the girl on his phone is his girlfriend, Ogino replied that it is, but technically, Ishigami didn't specifically ask if it was Otomo, and thus Ogino unintentionally shot himself in the foot.
Eyes Never Lie: When he tells Ishigami, who was accidentally eavesdropping, that it was his "girlfriend" on the phone, Ogino's eyes shifted to the opposite side. Which only helps confirm to Ishigami that he's lying.
Face of an Angel, Mind of a Demon: He has the appearance of a bishonen, but is a rather sexually depraved individual deep down.
Hate Sink: He was cheating on Otomo, and tried to buy Ishigami's silence when he found out (by offering to let him sleep with her). Then he pulled a Wounded Gazelle Gambit, making it look like Ishigami was a Stalker with a Crush, and threatened to hurt Otomo (it's implied that he would have released revenge porn) if he revealed the truth. Those who know the truth about him rightfully find him despicable, and Kaguya and Shuchi'in's most influential students made sure that Ogino will never come back to Shuchi'in or Otomo again.
Hidden Eyes: Curiously, his eyes are omitted completely in both the anime and the tankobon release of Chapter 88 of the manga. In the original release of the chapter, his eyes were fully drawn and detailed like mostly everyone else.
Karma Houdini Warranty: Chapter 89 made it seem like Ogino was able to get away with turning Ishigami into a pariah until Chapter 90 revealed that Kaguya told the truth of the situation to the Shuchi'in VIPs that forced Ogino to transfer.
Lack of Empathy: Deep down, Ogino makes it clear to Ishigami that he doesn't care about Otomo's wellbeing and feelings in the slightest, with the only good thing about her being sexual relief. Unsurprisingly and later tragically, Ishigami gives him a No-Holds-Barred Beatdown.
Manipulative Bastard: After his attempts to buy Ishigami's silence caused the latter to attack him, he used his popularity and skill as a member of the drama club to frame Ishigami as a Stalker with a Crush.
Psychotic Smirk: He gives a very scary one when he warns Ishigami of what he'll do to Otomo if the former were to reveal his Casanova nature.
Pyrrhic Victory: Sure, he may have got off scot-free for his crimes and pushed all the blame onto Ishigami at first, but he'll spend the rest of his life being paranoid of Ishigami deciding to spill the beans or come back looking for revenge. And the fact that he's barred from attending Shuchi'in Academy any longer means that his life is pretty much derailed by his standards.
Raven Hair, Ivory Skin: He has black hair and a pale complexion, but is a very popular and well-liked student. It goes into Eerie Pale-Skinned Brunette territory when his true colors are revealed.
Really Gets Around: Besides Otomo and the unnamed girl on his phone, it's implied that Ogino has really been busy.
Small Role, Big Impact: He only shows up in 3 chapters (and all those appearances are in flashbacks), but he's single-handedly responsible for turning Ishigami into the person he was at the beginning of the manga.
Stepford Smiler: His kind smile is nothing more but a mask to hide how depraved he is.
Villain with Good Publicity: He was one of the most popular students in middle school, meaning that with his word against Ishigami's, and his acting skills, it was obvious whose side most students and teachers would pick. This quickly gets revoked by the school's most influential students and club leaders, who alongside council vice-president Kaguya evict and ban him from Shuchi'in's premises, destroying his reputation.

Betsy Beltoise

Voiced by: Sally Amaki (Japanese), Morgan Garrett (English)

Debut: Chapter 20 (Manga), Episode 4 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/betsy_87.png

The student council vice-president of the French Shuchi'in Academy. She boasts a very sharp tongue and wit, which she puts to use as an acclaimed debater in France, winning two consecutive victories in the French Debate Meet.

Break Them by Talking: Her specialty. Betsy uses quick thinking and logic to coerce her victims into digging their own graves. Attempting to do this to Shirogane ends up backfiring on her in two respects: Shirogane doesn't understand French, and Kaguya sees fit to retaliate by giving Betsy a taste of her own poison.
The Bus Came Back: She makes her second appearance in the series 219 chapters later. Justified by the fact that she's a French student who only came to Japan for the annual party and her experience with Kaguya traumatized her into avoiding any semblance of contact with the Shinomiya family.
Disease Bleach: In the anime, her hair takes on a tinge of gray from being on the receiving end of Kaguya's verbal assault.
The Dreaded: Is known as "Betsy the Wound-Licking Dagger." It is said that she will one day kill a man with her tongue.
Eloquent in My Native Tongue: She learned enough Japanese to hold a conversation between her first and second appearances, though her sentences are very stilted. On the other hand, she's a skilled debater in her native French.
Femme Fatale: Definitely appears like one. Points for actually being French as well.
No-Sell: Her verbal assault upon Shirogane completely fails due to his inability to actually speak or understand French.
Punch-Clock Villain: Arguably so, since her verbal assault upon Shirogane was ordered directly by the Japanese Shuchi'in Academy principal, as a Secret Test of Character for him.
Red Eyes, Take Warning: Her eyes are blood-red, as befitting her ability to break people with her words alone.
Student Council President: She's been elected to the position by the time of her second appearance.

The Four Ramen Emperors of Tokyo

Voiced by: Haruo Sato (San of Shibuya), Takahiro Yamaguchi (Young San of Shibuya), Takeshi Maruyama (J Suzuki of Koenji) (Japanese), David Wald (San of Shibuya), Ben Phillips (J Suzuki of Koenji) (English)

Debut: Chapter 43 (Manga), Episode 11 (Anime)

A set of ramen connoisseurs, known for being the best ramen eaters in the entire metropolitan area. They go by their titles: San of Shibuya, J Suzuki of Koenji, the Immortal of Sugamo, and the Glutton Girl of Jinbocho.

Ambiguously Related: The Immortal of Sugamo's last name is Tanuma, implying a relationship to Tsubasa.
Big Eater: The Glutton Girl of Jinbocho's ramen eating style. Apparently she was once known as the "Ramen Vacuum-Cleaner". This brought her at odds with San of Shibuya, whose style consist more of refined preparations and eating.
Brought to You by the Letter "S": When not working as a taxi driver, J Suzuki of Koenji wears a bandana with the letter J on it.
Elite Four: Played for Laughs, as they are the four greatest ramen eaters in the city.
Hero of Another Story: Their exploits are completely detached from Kaguya and Shirogane's Battle of Wits, and their paths only rarely cross with the rest of the cast.
Minor Flaw, Major Breakup: As a testament to how seriously they all take ramen, San of Shibuya used to date the Glutton Girl of Jinbocho but broke up with her (despite admitting that he still loved her) because she ate ramen a different way.
Only Known by Their Nickname: While all four of them have names, they are normally only referred to by their titles.
Recurring Extra: J Suzuki of Koenji occasionally shows in the story in his day job as a taxi driver.
Serious Business: Ramen, obviously.
The Smurfette Principle: The Glutton Girl of Jinbocho is the only girl in the group.
Trademark Favorite Food: Ramen, obviously, for all four of them.
Unaffected by Spice: Subverted for The Immortal of Sugamo - he believes himself to be this because of all the ultra spicy food he'd eaten when he was younger, but he soon discovers that modern Blazing Inferno Hellfire Sauce is 60 times spicier than any "ultra spicy" food he'd ever eaten.

Gomanosuke

Debut: Chapter 211 (Manga)

A black cat belonging to the Abe family who is frequently found wandering around the school grounds.

Caligula's Horse: Iino appoints him to be her General Affairs Officer when she's elected since she's having trouble finding qualified people to fill the positions. Given that Shirogane went his entire second term without having the position filled and Iino's council is also noted to be far more efficient, it probably isn't that big of an issue.
Jerkass to One: For some reason, he doesn't like Shirogane. We're never told why, but it's probably just because he finds Shirogane's glare intimidating.
Named After Someone Famous: Kaguya initially gives him the name Edward of Woodstock before learning that he already had an owner.
Non-Standard Character Design: Outside of the one-shot characters that Maki meets on her trip to India, he's the only one who is drawn in a semi-photorealistic manner.^note
Team Pet: He effectively becomes something of a mascot for the student council in the latter half of Shirogane's second term.

The Narrator

Voiced by: Yutaka Aoyama (Japanese), Ian Sinclair (English), Renato Rosenberg (Brazilian Portuguese)

Debut: Chapter 1 (Manga), Episode 1 (Anime)

The narrator of the series, providing commentary and context to Shirogane's and Kaguya's Battle of Wits.

Catchphrase: "Uso de aru" ("That was a lie") whenever he starts to explain how a character is being dishonest regarding exams.
Dub Personality Change: The narrator is much more of a Lemony Narrator in the English dub of the anime, prone to both being far more personally invested in the character drama (for example, audibly crying when the student council shares their photos with Kaguya after her phone breaks) and making far more humorous asides.
Interactive Narrator: Played for Laughs when he is chewed out by Kaguya for trying to psychoanalyze her.
Large-Ham Announcer: He introduces the contestants in the student council's arm wrestling match as though it were professional wrestling.
Lemony Narrator: He's prone to breaking his role as a straight-laced if dramatic observer from time to time. Just take a look at Chapter 17, where he screams "Marriage!" to symbolize how good cat ears look on Kaguya and Shirogane.
Mundane Made Awesome: A huge part of the narrator's function in the series serves this end. His dramatic narration treats moments like two teenagers trying to trick each other into revealing their cell phone numbers like something from Death Note.
Narrator: Well, yeah.
O.O.C. Is Serious Business: In the English dub of the Anime, the few times the narrator isn't a Large Ham Lemony Narrator is usually a sign that something significant is going to happen in one of the main characters' story arcs, most notably when Kaguya and Shirogane meet up in the clock tower at the end of the Cultural Festival arc.
Opening Narration: Gives one in the first two episodes of the anime and Chapters 1 and 11 of the manga, where he provides the viewpoint that animates Kaguya and Shirogane's stubbornness: love is war, and the one who confesses first loses!

Let my heart be consumed and set ablaze!
Burning in flames of our love!
