Manga / Himouto! Umaru-chan

Looks can be deceiving.

Umaru Doma, age 16, is the perfect girl at school and around town; beautiful but with a kind heart, athletic, always gets high test scores, and while popular remains humble and is greatly admired by students and faculty alike, but...

Umaru at home is a barely functioning otaku slacker who lives with her white-collar worker brother, Taihei, who more or less caters to her every whim due to being easily nagged into things. Can Taihei fix his broken sister, who would rather eat junk food and play video games all night than go outside and play, or will his weak will allow her to become a complete shut-in?

Himouto! Umaru-chan (干物妹!うまるちゃん) is a manga series written and illustrated by Sankaku Head, which was serialized in Weekly Young Jump from 2013 to 2017. It received an anime adaptation directed by Masahiko Ohta for Dogakobo (Monthly Girls' Nozaki-kun and Plastic Memories) in the summer of 2015, an OVA in October 2015, and another in April 2017. A second season (Himouto! Umaru-chan R) premiered on October 9, 2017.

Has a couple of spin-offs by the same mangaka — Himouto! Umaru-chan S, set in an Alternate Universe, and Akita Imokko! Ebina-chan, a side-story following Umaru's friend Ebina from when she first arrives in Tokyo. The manga itself received a sequel in Weekly Young Jump again, titled Himouto! Umaru-chan G.

---

Himouto! Umaru-chan contains the following tropes:

A-M

• 10-Minute Retirement: At one point Umaru realizes she has been quite active with her friends and decides that she will give up the Himouto lifestyle. She even decides that she will tell her friends about her double life, but when the time comes she is so visibly afraid that her friends will abandon her that Kirie says they don't need to know and that they love Umaru unconditionally.
• All Work vs. All Play: All-work Taihei spends nearly all his time at work or taking care of Umaru or the house, while all-play Umaru is a lazy bum.
• Aloof Big Brother: Inverted. Kirie is Bomber's aloof little sister. Bomber keeps trying to get closer to her, but Kirie is having none of it.
• Ambiguous Ending: The ending of the spin-off Akita Imokko! Ebina-chan shows that Ebina works in an restaurant called "Taihei", but it's ambiguous with whom she works in the restaurant or if she succeeded in her love since the chef in the restaurant could either be Taihei or her brother Kouichirou who look alike with the only difference being their eyes and Tahei having a 'horn' which in turn are hard to see since they don't show the eyes of the chef who in turn wears a chef hat that conceals his hair.
• Ambiguous Situation: Chapter 89 ends with what seems like Ebina about to confess her love to Taihei. Chapter 90 begins next morning with Taihei and Umaru and no real hint of what happened as a result other than Taihei preparing New Year's money for Ebina when in previous years he only did so for Umaru. Chapter 92 mentions that he listened to it seriously, but doesn't elaborate any further. It isn't until chapter 98 where readers learn what actually happened: She didn't confess.
• Author Avatar: Sankaku Head's avatar is the character with the white, cylindrical head^note ironically enough, since his name means "Triangle Head" and hamster face. He pops up a lot in the anime, including in scene transitions, but special attention is drawn to him in the last episode, when Taihei is test-driving an SUV and freaks out over "nearly" hitting him while he was crossing a crosswalk, causing Taihei to shout "A MANGAKA!"
• Author Appeal: This is a manga that focuses on a brother/sister relationship, and every major female character in the series seem to have an older brother. Clearly, the author is a fan of the Little Sister Heroine trope.
• Bland-Name Product: Several. Zonama for Amazon, Gapcom for Capcom, Batsune Migu for Hatsune Miku, Jun Piece for One Piece, Pokéham for Pokémon, tmetter for Twitter, Anohi beer for Asahi beer, Anumate for Animate, Haagen-Dosz for Häagen-Dazs, nitenno for Nintendo, NcDonald for McDonald's, Doll for Dell, Nukon for Nikon, Sbrite for Sprite, Pokee for Pocky ...
• Breaking the Fourth Wall: Umaru pushes away the split screen with her brother berating her for being a picky eater in episode #10.
• But You Were There, and You, and You: In the Or Was It a Dream? storyline about getting Trapped in a Videogame from Himouto! Umaru-chan S (It Makes As Much Sense In Context), the NPCs look like people Umaru and her friends know from real life. Notably, Umaru and Kirie ran into NPC Taihei who owns a store together with his wife(?) Ebina... That's it, the real Ebina who found him first after getting sucked into the game too and basically was ignoring game rules and playing house by treating NPC Taihei as a Doppelgänger Replacement Love Interest of sorts.
• Censor Steam: Joked about in one of the "Himouto Umaru-chanS" shorts. The hotspring conveniently allowed bathing suits, so they didn't have to worry about clouds of steam or weird beams of light popping up.
• Clark Kenting:
  • When it looks like Kirie has discovered her double life, Umaru is able to fool her into thinking that her home self is actually her little sister "Komaru".
  • Umaru hides her identity for a game tournament by pulling on a domino mask and becoming "U.M.R." It convinces Sylphin, who recruits her to... help her beat Umaru. It also convinces Bomber, who's under the impression U.M.R. is a guy, much to Umaru's confusion.
  • Kirie fools her own brother during a trip to an aquarium by wearing a straw hat.
• Clingy Jealous Girl:
  • Downplayed: Umaru tries to monopolize her brother, but more out of annoyance that she doesn't have his undivided attention than any romantic feelings.
  • Kirie often gives anyone paying too much attention to Umaru a Death Glare.
  • Kanau doesn't seem very happy in episode 5 when she overhears that Taihei's homemade food was made by his girlfriend (the truth being that he made it). He then lies to his colleagues and says his younger sister makes them, prompting a sigh of relief from her.
• Cool Big Bro:
  • Taihei is pretty much Umaru's father at this point, but he's very loving and caring towards her.
  • Bomber tries to be cool, and while he doesn't entirely succeed, it's obvious he deeply cares for Kirie and wants to be closer to her.
• Crazy Jealous Guy: Bomber in chapter 34/episode 7 while eating at a restaurant with Taihei. He cries over meeting a woman at a mixer, only to find out she's already got a boyfriend. He then gives Taihei several Death Glare looks, and switches to a normal face while the waitress brings his food to the table. Then he complains that he's heard Taihei walking around with a beautiful woman, who he assumes is his girlfriend. When Taihei says it's just his sister, Bomber doesn't believe him at first.
• Cuteness Proximity: Taihei adores cats. In episode 7 he follows one around for so long that he ends up in an unfamiliar neighborhood.
• Dancing Theme: R's ending, "Umarun Exercise," has Umaru leading the main cast in a combination exercise/dance.
• "Do It Yourself" Theme Tune: Aimi Tanaka (Umaru) sings the first season's opening theme solo, while she shares its ending song with Akari Kageyama (Ebina), Haruka Shiraishi (Kirie) and Yurina Furukawa (Sylphin).
• Early Installment Character-Design Difference: This gets referenced in the first Umaru-chanS short, where the "prototype" Umaru shows up and quickly annoys Taihei, complete with the butt-pinching prank.
  Taihei: Wait, the taller one is more like Umaru before her character was finalized. What is the manga version doing here?
• Early-Installment Weirdness: In the "prototype" manga, Umaru is far more mean-spirited and childish than in the final version, doing things like like pinching Taihei's butt with a grabber arm toy, hitting him in the groin (though this is seemingly an accident), and making her classmates think that he's physically abusive by lying about an injury she inflicted on herself while throwing a tantrum. Additionally, "Indoor Umaru" isn't fully super-deformed, instead looking like a more realistic pre-teen girl.
• Even the Girls Want Her:
  • More than a few girls can be seen admiring Umaru along with the men. Then there's Kirie, who has a massive crush on Umaru.
  • At least as many girls as guys are seen staring at Ubina's large breasts during her flashback, including the flight attendant.
• Foreshadowing: There are a lot of chapters that show Ebina reacting oddly to Umaru and Taihei bonding, later revealed to be because she hasn't seen her own big brother for a while and is looking for him.
• Freeze-Frame Bonus: Near the end of Episode 3, Umaru has an Imagine Spot where she sees the ghosts from the horror movie she just watched. However, there is a very brief scene that shows the ghost boy, the ghost girl, and a ghost man/rapper moving around as if singing and dancing in a music video, and looking rather comical.
• Godlike Gamer: Umaru's gamer alter-ego "UMR" is one of the top gamers in Japan. At the arcade she frequents, she's able to pull off impossible maneuvers on the arcade machines so that she can get hundreds of prizes in one turn. The arcade staff have come to resent her inhuman success and fear she'll risk bankrupting them.
• Gossip Evolution: In one story, Umaru overhears some girls discussing rumors about her, such as her brother is handsome, her father is German, and there's a library in her house. Umaru isn't quite sure how those rumors started, but realizes after spending the day with Sylphin that all the rumors apply to her and got turned around such that people think they're about Umaru.
• Gratuitous English: Episode 4 uses English when calling out the players in the competition by the initials they often use in the games, such as Umaru being "U.M.R.".
• Harsh Word Impact: After Taihei throws out a figurine box that Umaru nonchalantly claims she didn't need, she is surprised that she told him to. But she decides to guilt trip him anyway, and turns on the waterworks. Several of her insults hit him rather hard, with arrows piercing him each time.
• Hidden Depths:
  • Kirie is actually very good at sports and despite being good enough at swimming to get third place in a national tournament she has no plans to go pro, instead wanting to write and draw children's picture books.
  • While Ebina is always blushing, she is actually more active in getting friends than Umaru.
  • Despite the attention-craving and obsessive "competing" with Umaru, Sylphin is actually quite a nice person who has no problems becoming friends with Umaru (and her gaming alter-ego) & co.
• Hikikomori: Unless forced to, Umaru would never leave her house.
• Hoist by His Own Petard: In one scene during episode 2, Umaru attempts to force her brother awake by sleeping next to him and making him uncomfortable so she could play games with him until the morning anime started. Unfortunately she had been up all night, so she actually falls asleep, and doesn't wake up until evening. As a result, she misses both the morning and the afternoon anime shows. (Much the same happens in chapter 3, which the scene was based on, although Umaru only misses the morning anime.)
• Idiosyncratic Episode Naming: Most chapter titles are in the format "Umaru and [X]", although Ebina, Taihei and Kirie have all substituted for Umaru.
• Imaginary Love Triangle: Ebina doesn't know Kirie considers her a rival for Umaru's affections. Vice versa, Ebina considers Kirie to be a rival for Taihei. They later realize the mistake, with Kirie even becoming a Shipper on Deck for Ebina/Umaru.
• Imagine Spot: Umaru in chapter 24/episode 7, while eating at the ramen restaurant, goes into Super-Deformed mode, and claims that cola would go great with the ramen she was eating. It then turns out to be her imagining all this, while she eats the ramen normally.
• Imagine Spotting:
  • Umaru can somehow read the thought bubbles of the hamsters in episode #1, is also somehow aware of her brother's thought bubble about her indoor-persona in episode #2, even waving it away as if it were actually something tangible like smoke or vapor and sees how her brother imagines the bad effects A/C overuse would have on her.
  • Taihei to be aware of the massive amount of snacks Umaru imagines and wants him to buy during a festival in sequel episode #8.
• Inelegant Blubbering: Umaru is prone to crying and throwing a hissy fit like a little child every time she doesn't get her way, provided no one else she knows is around.
• In-Series Nickname: Umaru gets several nicknames from different people: Kirie calls her (or rather, "Komaru") "Master", Alex calls her "Sempai", and Bomber calls her "Tanukichi" due to mistaking her hamster hood for a Tanuki. And of course she has U.M.R., her "gamer name".
• Just One More Level!!: In episode 3 of Himouto! Umaru-Chan R. Umaru becomes addicted to a video game and becomes obsessed with obtaining rare items, Like Alex and several Japanese, After following Ebina's advice, Taihei decides to join Umaru and teach her to truly enjoy video games, but once they finished the game, The sequel is announced and the cycle repeats
• Lonely Rich Kid:
  • Ebina casually says things once in a while that imply she's rich, and she has trouble making friends. When Taihei visits her flat, he notices she has a fancy kitchen with two refrigerators, further adding to this. That said, she does have friends in Akita, and didn't have enough money for a second fridge when she first arrived in Tokyo.
  • Sylphin is revealed to be rich but seems to have no other friends beside U.M.R.(Umaru).
• Loves My Alter Ego: Umaru has this issue with her friends. Ebina, Kirie and Sylphin, as far as they know, are friends with outside Umaru, Komaru and U.M.R., respectively. They have either not seen Umaru's real self (Ebina) or don't realize the person they know and Umaru are the same person (Kirie and Sylphin). Later Kirie and Sylphin become friends with outside Umaru but still don't know that Komaru and U.M.R. are the same person as Umaru.
• Married to the Job:
  • Taihei works overtime all the time and has little to no hobbies outside of cleaning after Umaru. On his one day off, he started zoning out because he had nothing to do.
  • Kanau has a bedroom in the building she works in. Her father is a company president and instilled a strong work ethic into her.
• Meaningful Background Event: Throughout the first two episodes of the anime, Kirie can be seen in the background of several school shots, silently glaring at Umaru. In Episode 3, after Umaru finally notices her doing it, Ebina points out she's been doing it all the time and there's a brief montage of several such shots, with the glaring Kirie highlighted.
• Meaningful Name: "Doma" can mean "in the ground." So, Umaru's name means "buried in the ground," "Komaru" means "trapped in the ground," and Taihei, "rest in peace." Komaru is also a pun on "child" in Japanese and "Umaru". Putting them together makes "Komaru".
• Mundane Made Awesome: Sylphin appears with some flowers as a backdrop during episode 4. The camera then switches angles to reveal that it wasn't due to Bishie Sparkle; rather, she somehow managed to bring a flowery background onto the tennis court. She later crashed into it a few times while playing tennis against Umaru.

N-W

• Nice Job Breaking It, Hero: Umaru accidentally spills soda on the cable modem under her brother's desk in episode 10. She then tries desperately to connect various devices online, only to find out none of them will connect, and suffers a brief Heroic BSoD due to not being able to connect to the net.
• No Sense of Personal Space:
  • Umaru often Glomps onto Taihei while in Super-Deformed mode, whether he's okay with it or not.
  • Kanau likes to get really close to Taihei at work, close enough that she's within kissing range of his lips. Since he's Oblivious to Love, as well as being her subordinate, this makes him uncomfortable, as well as missing the point that she likes him.
• Oblivious to Love: Taihei doesn't notice Ebina's or Kanau's feelings for him and Umaru seems to have no idea that Kirie wants to be more than friends.
• Odd Friendship:
  • Kirie became friends with both forms of Umaru, and both friendships are odd, in different ways.
  • Sylphin wants to beat Umaru with her new friend U.M.R's help.
  • Inside Umaru also gets along quite well with Bomber because both of them are easygoing people by nature.
• Officially Shortened Title: Spoofed in Umaru-chan R episode 3, where Alex brings over the popular new Dating Sim, "My Little Sister is My Girlfriend (Boom)" ("Imouto wa Girlfriend Kakko Baku"), or "ImoBaku" for short.
• Once a Season: Starting with chapter 10, the opening panel of every tenth chapter is by another light novel/manga artist. (The pattern's broken for the final one, with chapter 99 getting a contest winner's opening panel instead of chapter 100).
• One Degree of Separation: Bomber and Alex are introduced as Taihei's co-workers, with Bomber as an old school buddy. They are later revealed to also be the older brothers of Umaru's friends Kirie and Sylphin respectively. During his business trip to Hamamatsu, Taihei works with someone who's all but explicitly said to be Ebina's missing brother. It also turns out that Bomber knows Sylphin through Alex. What makes this even weirder is, almost nobody realizes these connections (i.e., Taihei knows Sylphin is Umaru's friend, but doesn't realize that she's Alex's little sister).
• Orgasmically Delicious: Umaru seems to have something of an orgasm when drinking cola.
• Otaku:
  • Umaru is totally obsessed with Anime and gaming merchandise, and hoards a pile of them at home.
  • Alex and Umaru become good friends due to their shared, powerful love of anime.
• Perpetual Expression: Umaru's pet hamsters always maintain the same look on their faces.
• Pet the Dog: For all the abuse she heaps on Taihei, Umaru is given a lot of moments where she does genuinely end up appreciating all the things he does for her. Especially if it's pointed out by another character, such as Ebina commenting that chopping up green peppers takes a long time to prepare when Umaru finds some in her lunch.
• Primal Fear: Umaru becomes very concerned when Taihei is lying on the floor with a high fever, fearing he could die from it, instead of playing a prank on him. She attempts to do what she can to help him get better.
• Product Placement: Parodied in Umaru-chan R episode 5, which opens with an ad for Diamond Service, the company Taihei works for. At the end of the ad Umaru drops in to deliver the traditional "Our program was brought to you by this excellent sponsor!" message; Taihei asks if his company is really sponsoring the anime, and a caption appears overhead reading "Nope."
• Pun-Based Title: "Himouto" is a portmanteau of "Himono"^note As Sentai Filmworks puts it in a translator's note, "a colloquialism that refers to 20-something women who give up on dating and laze around the house like a dried fish". and "imouto" (little sister).
• Real-Place Background: The series is set in Hachioji, Tokyo.
• Relative Error: People often get jealous of Taihei after assuming Umaru is his girlfriend.
• Shipper on Deck: After figuring out that Ebina likes Taihei and after receiving some unwitting advice from Umaru, Kirie decides to support Ebina's feelings and even tells the latter of her intent.
• Shout-Out:
  • The first season's opening contains parodies of Pokémon, Mario Kart, Monster Hunter, and Disney Tsum Tsum; the song itself actually contains the infamous death noise from Super Mario Bros..
  • Umaru is a fan of Jun Piece, which she reads in Junpu; her favorite character is "that cute reindeer", a parody of Tony Tony Chopper.
  • Umaru and Sylphin's favorite fighting game is Space Stream Fighter IV; Sylphin's character of choice looks a lot like Fi. The game also has a character who's just plain Guile, no changes or attempts to hide his identity. In Umaru-chan R, she has a poster for Space Stream Fighter V in the apartment.
  • One of the employees at the Gapcom game center has a white headband, fingerless red gloves, and Big Ol' Eyebrows, making him look just like Ryu.
  • In the manga version of the Stream Fighter tournament, the other contestants include Satoshi, Bayonetta, Shinya Arino, and Segata Sanshiro.
  • In one of Sylphin's flashbacks, we see that what got her into fighting games was watching a tournament which was won by U.M.H. — in other words, legendary Street Fighter champ Daigo Umehara.
  • In the Umaru-chanS shorts, the Imouto Sentai Umaranger costumes are heavily based off of Mahou Sentai Magiranger.
  • When Umaru and Taihei have a "trial" to deduce what happened to Umaru's pudding, he dresses up like Phoenix Wright, even shouting "OBJECTION!", while Umaru's hoodie changes to one of Monokuma, up to imitating his Signature Laugh.
  • Umaru's inner dialogue over choosing what snacks to buy is portrayed like the SEELE conferences from Neon Genesis Evangelion. Umaru 06 even strikes the Gendo Pose.
  • Umaru is briefly shown dressed up as Black Jack in one "Himouto! Umaru-chan S" short.
  • When Umaru went out at night to buy cola, she deluded herself into thinking to know how to perform martial art moves from playing Metal Greek Salad (in the dub that was changed to Metal Geo Risotto or something like that).
  • Before Umaru goes to the convenience store at night, she's afraid of some kinda Jason Voorhees knock-off lurking in the night, as was her brother after he found out about her sneaking off in the night alone (Umaru imagined him with a nailbat, her brother with a chainsaw like in the original franchise but with a weird mask).
  • She once pestered her brother about her achievements in a game called ShinColle.
  • When she and Sylph visited an old-fashioned Japanese candy store, they found an Gangnam action figure.
  • The girls end up going to see a movie that looks suspiciously like Case Closed.
  • When Umaru and Sylph visit an Anumate animé merchandise store, they find, among other things, PreCura (including a toy version of the Love Guitar Rod), Puella Magi Mackerel Marlina (the poster showed Homura and Kyubey with fish headmasks) and Ganbam (with Umaru imagining herself wearing an Gundam cardboard box and a colony cylinder in the background) merchandise.
  • Chapter 141 has UMR, Sylphin, and Bomber playing Dead 3 Zombies at the arcade^note If this seems odd, bear in mind that Left 4 Dead 2 was popular enough in Japan to merit an arcade release.
  • Umaru wanted to watch Pokeham the Movie 2000 with her hamsters.
• Sick Episode: Umaru catches a cold in chapter 22/episode 10, due to sleeping on the floor with the A/C on. The very next day, Taihei catches her cold, and Umaru initially plans to cook some hot and spicy foods as payback for him not staying home to take care of her the previous day. But when she arrives home and sees that his fever went up, she forgets about her revenge and tries to help him get better instead.
• Signature Shot: As with his other works, director Masahiko Ohta puts a high-energy shot of the camera racing through the environment in the first episode. This time, it follows Umaru as she scampers across her living room, zips under the table, and lunges over to her computer.
• Similar Squad: Ebina's friends from Akita are very similar, personality-wise, to Ebina, Kirie and Umaru.
• Situational Sociability: In public, Umaru is The Ace, a straight-A student and stellar athlete. At home, Umaru is a lazy, spoiled brat who would rather sit around playing video games or reading manga than do anything productive. The difference is so stark that there are instances of her being mistaken for two different people.
• Slice of Life: The series focuses on Umaru and her daily life at school and home, with the occasional spotlight on the other characters such as her brother Taihei.
• Sock Slide Rink: When Umaru visits Sylphynford's manor (under her U.M.R persona), Sylph shows her around, sliding along a wood floor at one point in her stockings.
• Spirited Competitor: Sylphin loves competing against people and will enter any competition or game just to prove her skill, though she dislikes gambling games that rely on luck. She has singled out Umaru as her ultimate rival, but holds no actual hostility toward her, in fact it's a strange attempt at becoming friends. It turns out that she gets it from her mother, who's not satisfied unless she wins first place.
• Spooky Photographs: When the quartet (Umaru, Ebina, Kirie and Sylph) made photos for amusement park IDs, Kirie's photo showed ghosts bursting out from behind her.
• The Stinger:
  • After the end credits in episode 3, we jump into something that looks straight out of a horror movie - because that's exactly what it is, a horror movie Umaru and Taihei are watching.
  • In episode 8, Kanau shows up behind Bomber and Taihei as the two are stuck at work on Christmas Eve. After the credits roll, we are then shown the events from her point of view, including Taihei inviting her to hang out with him and Bomber like they used to. She politely declines, but the look on her face shows she really wanted to. He later sends her a picture of him and Bomber in Santa suits. She promptly crops the picture to show only him, then sets it as her phone's wallpaper.
• Strong Family Resemblance:
  • The few glimpses we get of Mrs. Doma (usually thanks to Taihei's memories) show that she looked and sounded like an adult version of Umaru.
  • Ebina looks a lot like her mother, even picking up a couple of her mannerisms.
• Stuff Blowing Up: Spoofed in Umaru-chan R Episode 3, where Alex shows off a Dating Sim called "My Little Sister is My Girlfriend (Boom)", which is set in a former mining town where there's apparently leftover sticks of dynamite lying around everywhere that randomly goes off and blows up objects (and people).
• Super-Deformed: The moment Umaru walks through her front door she becomes a chibi with a Playful Cat Smile. In a hundred chapters and a couple thousand panels Umaru has only appeared non-deformed while indoors twice, and one of those was a chapter opening. This isn't merely an Art Shift but an actual physical change that can even fool Umaru's friends and which is referenced a few times in the manga.
• Supreme Chef: Taihei is quite the good cook, and ends up making food for himself and Umaru. However, both of them lie to friends and coworkers when they claim it's Umaru who makes them. For Taihei, Bomber, and to a lesser extent, Kanau, don't believe he could cook food that good himself. Umaru meanwhile doesn't want to ruin her perfect student persona at school when she claims she makes the food.
• Sure, Let's Go with That: When Kirie suggests inside Umaru is Umaru's younger sister, Umaru runs with it and introduces herself as "Komaru."
• Take That!: Both the manga and anime have a story that takes a shot at Nisekoi, with a Rom Com manga named after Nisekoi where the female lead's Love Confession is drowned out by a train suddenly passing by, which annoys Umaru and Kirie.
• Two Guys and a Girl: Taihei, Boomer and Kanau in high school always hung out together.
• Two-Timer Date: Umaru and the other girls hang out at Sylphin's house on Christmas Eve, and Sylphin says that she invited her other friend UMR, which she doesn't know is Umaru's gamer handle. Thankfully it all works out because Umaru is given legitimate excuses for leaving early as Umaru^note Sylphin falls asleep so the girls leave her Merry Christmas notes and leave her in peace and showing up late as UMR^note Sylphin's invitation didn't get to Umaru's phone until two hours after it was sent, because of the heavy cellular traffic.
• Unknown Rival: Sylphin considers herself Umaru's rival. Umaru doesn't seem all that interested. Once they become friends, Sylphin lets the rivalry go.
• Unsound Effect:
  • "Umaru~un", the sound effect of Umaru's amazingness, which happens whenever she shows up in her outside form. The anime turns it into a sort of transformation sound for when Umaru transitions to her "indoor form".
  • "Shba~an" is used every time Sylphin, her mother, or her brother turn up.
• Weird Crossover: One chapter's splash page celebrates Umaru-chan and One-Punch Man getting Animated Adaptations^note both series are published in the same magazine with a picture of Saitama carrying "slacker mode" Umaru in one hand.
