Number 9 Elementary School
open/close all folders
Alien Party
The group designated to take care of alien-related problems around school. One representative from each sixth-grade class is usually chosen (by volunteer or by default) to fulfill the position, and then given a Borg to assist them with pacifying and maintaining the aliens they fight and catch. Anyone in this position will usually be under close inspection from their advisor to see if they can fuse with aliens.
Tropes associated with Yuri:
Tropes associated with Kasumi:
- Almighty Janitor: For a group of people who are just supposed to deal with aliens around school, they certainly have a lot of power. They have the jurisdiction to check out other schools' alien problems, and even get resources enough to perform space travel missions.
- Badass Adorable
- Break the Cutie: They all start off as relatively normal little girls, but the more they learn about the aliens and what they're up against, the more they all start to fall apart.
- Beauty, Brains, and Brawn: Kumi serves as the brains, Kasumi serves as the brawn (although she's noted to be pretty as well), while Yuri serves as the Beauty (at least personality-wise, since she's otherwise physically plain).
- Blessed with Suck: Alien Party members get to go to any high school of their choosing and skip out on certain classes and tests. The problem with this is that Alien Party members are also stuck dealing with aliens of varying levels of ferocity. They're also secretly subjected to fusion with an alien, but most children don't take to it well and these girls are nearly killed when they eventually fuse with an alien.
- Chromatic Arrangement: In the anime OVA, Kumi, Kasumi, and Yuri's eyes are blue, red, and green respectively instead of the black (and later on, green) eyes they all have in the manga.
- Color-Coded Characters: Their alien hunting clothes (really their gym clothes with extra padding) are colored after their class' namesake flower/fruit. Yuri is Red (for the camellia), Kumi is Purple (for wisteria), and Kasumi is pink (for peach). These colors carry over when they move into junior high school.
- Dark and Troubled Past: Kasumi and Kumi have them.
- Freudian Trio:
- Id: Kasumi (The McCoy) — Joined because she likes catching/fighting aliens. Also contrasts with Yuri in that she is a prodigy and a xenophile. Also serves as the red oni to Kumi's blue.
- Ego: Yuri (The Kirk) — Railroaded by her classmates since no one else wanted to be stuck wearing the alien. The opposite of Kasumi in that she is a crybaby who despises all things alien.
- Superego: Kumi (The Spock) — Chose to be an Alien Fighter rather than be saddled with the higher pressure and responsibility of Class President (little did she know...) but is also the thinker and The Stoic of the group. Also serves as the blue oni to Kasumi's red.
- Girlish Pigtails: Both Yuri and Kasumi sport this.
- Kid Hero: All of them are twelve years old when they're first put into the Party. They're a little older by the time Emulators happens, but between the original series and Emulators they're elementary to middle school kids.
- Nice Mean And In Between: Yuri is usually respectful to anyone who bothers to interact with her, Kumi has less patience and makes that known, while Kasumi fluctuates between the two.
- Psychic Link: The more they use the Borgs, the more they can feel each other's emotions and pain. This applies to both alien and human, as they learn in Chapter 8.
- Prehensile Hair: Only after fusion with the aliens.
- Rollerblade Good: The trio use rollerblades to get around and to fight the aliens.
- Sharing a Body: Fully fused humans share a consciousness with the alien they fused with. Kumi and Kasumi have both fused with a Borg and a Yellowknife respectively, and both switch out with the alien sometimes. There are visual cues showing that they've fused at least.
- Technician vs. Performer: Ms. Hisakawa sees Kumi and Kasumi like this. Kumi uses her years of accumulated knowledge in order to find the best possible way to fight, while Kasumi uses her previous experiences in order to resolve situations. Yuri, unfortunately, did not have any merit at the time.
- Town Girls: Kumi is Butch, Kasumi is Femme, and Yuri is Neither. In terms of personality, Kasumi is the Butch, Yuri is the Femme, and Kumi is Neither.
- Trauma Conga Line: The girls do not have a great time in the Alien Party. Because of their experiences, Yuri cries every time she so much as thinks about having to go finish her job there, Kumi's gained a complex about her humanity, and while Kasumi is stoked to be there especially after fusing, she becomes much more violent as a result of her experiences.
Yuri Otani
- Voiced by: Juri Ihata (JP), Kelly Ray (EN)
A quiet girl, who was voted by her 6th-grade classmates to be their representative on the Alien Party. Yuri is very reluctant to merge with her Borg. She is easily frightened and there is hardly anything that won't make her cry, being scared or happy.
Tropes associated with Yuri:
- Bit-by-Bit Transformation: The single drill on her hair by the end of Emulators is the extent of her transformation and she's still human.
- Brainwashed and Crazy: She is forced to be used as a host for a Sunflower alien in Volume 3. She acts more confident under its control, but she's made to try and fuse as many people as possible regardless of their wishes. A part of her is not entirely brainwashed and leaks out when the circumstances concern her friends.
- Classical Anti-Hero: Physically weak, cowardly, shy, and unreliable, Yuri embodies very few heroic traits early on.
- Cowardly Lion: She's a huge scaredy-cat most of the time, especially when it comes to fighting aliens. However, despite her mental weakness she manages to put up with it for the whole year, and several years afterwards too.
- Damsel in Distress: There's not a day that goes by where Yuri isn't helpless in some way. Whether she gets taken by aliens, people using aliens, or just plain attacked, there's always some trouble she'll need rescuing from.
- The Eeyore: Becomes more so of one as the series progresses, and for good reason too.
- Emotional Regression: Along with some of her memories, Yuri reverts to a baby's mentality after she loses her Borg post-Lynax battle. She can still walk by herself, but she's lost the ability to talk and her friends often have to dress her. What is actually happening is that her memories have all transferred into her Borg, leaving her body a blank slate.
- The Generic Guy: Hisakawa's visit to her home reveals that she is completely average in every way; she has both her mother and father, has only average grades in school, her only hobbies are reading magazines and watching television, and she has no combat ability. Even her dislike of all things alien is simply something that most girls dislike as well, given her monologue in the first chapter. This is largely the reason why the Alien Party gets easy aliens for the early part of the story.
- Got Volunteered: The only reason she's on the Alien Party to begin with. Someone put her up on the vote for the Alien Party, and while there was only one other person on the vote, everyone decided Yuri would do it. This is also how she got suckered into Monami's alien fighting business.
- The Heart: As fragile as she is, Yuri often ends up being the cornerstone of the trio's emotional scenes, with either Yuri leading the charge in making the girls empathize with her or the other two taking time to bond as a group in order to cheer Yuri up.
- Idiot Ball: Volume 2 has her go into the Forest of Spaceships for whatever reason, resulting in her losing her Borg and her memories along with it. It's never explained why she went, and how she got in such a dangerous place to begin with, but regardless it was a really shortsighted decision.
- The Kirk: Unlike Kumi, who takes her duty with grim acceptance, and Kasumi who was enthusiastic about the Alien Party from the get-go, Yuri is a perfectly ordinary little girl who just wants to get back to her normal life. She has her moments of clever thinking, but they're often overshadowed by how terrified she is to deal with aliens.
- The Load: All she does whenever she is on duty is either get scared and cry, get in trouble and have Kumi and Kasumi rescue her, or both. However, it is a deconstruction: Yuri never wanted to join the Alien Party, knowing full well that she was afraid of aliens and would be a liability in combat, but was railroaded into doing so since nobody else wanted the job.
- Nervous Wreck: She freaks out quite easily.
- Only Sane Woman: She doesn't see the Alien Party as just a job or an exciting daily chore—to her, it's pretty much a death sentence and she treats it like one every time she's on the job. And while Kumi is able to put together that Kasumi isn't acting like herself, Yuri very quickly realizes that both of them have unusual behavior following their alien incidents.
- Prone to Tears: Even looking at her is enough to start the waterworks.
- Protectorate: Slowly becomes this to Kumi and Kasumi over the course of the series. In Kumi's case at first, this was because Yuri couldn't fight to save her own life, but we later see that Kumi's new Borg instincts compel her to live symbiotically with others, and she has designated Yuri as that person. Both she and Kasumi also want to prevent her from fusing with aliens and keep her human.
- Screams Like a Little Girl: Frequently.
- Shrinking Violet: She's very shy and sensitive.
- Tears of Fear: Frequently.
- Token Human: The only remaining human by the end of Emulators.
- Traumatic Superpower Awakening: After being mercilessly ganged up on by the Camellia boys, Yuri is unable to calm her Borg down and makes it overgrow itself, resulting in a mess of Prehensile Hair that attacks any alien in her vicinity.
- Why Did It Have To Be Aliens: She hates anything relating to aliens.
- You Remind Me of X: Yuri's generally passive personality reminds Kumi of a boy she used to know, Hideki Tamura. That's not a good thing, as Kumi despises Hideki and projects that hatred onto Yuri.
Kumi Kawamura
- Voiced by: Kaori Shimizu (JP), Deborah Rabbai (EN)
The most independent member of the Alien Party, and a 6th-grade student in the Wisteria class. She has been a member of the Student Council for years and has assisted her widowed mother in her writing activities as well as an above average number of chores for a student her age. She is eventually attacked by an alien and is revived by fusing with an alien from the Drill Clan.
- Adaptational Context Change: Both anime and manga have Kumi's initial death happen in the library, but it changes slightly. In the OVA, Kumi was just skating around the library without her Borg in tow, and her Borg crawled its way to her but couldn't get to the area in time. In the manga, she was deliberately looking for more knowledge concerning what happened to Kasumi, Borg with her.
- Adorably Precocious Child: In between the death of her father and her mother being too busy to raise her completely, Kumi felt like she had to grow up fast, and often tries to place herself in positions of authority. Her admission into the Alien Party was supposed to be a break from student representative duties, but she can't help but fall into her "responsible child" persona.
- Badass Bookworm: According to Hisakawa's notes, Kumi always puts her knowledge to good use when dealing with assignments and is always ready to solve a problem logically.
- Body Horror: After Kumi is resurrected, auger bits start tearing through her skin. Near the end her whole skin is destroyed, revealing that her entire body had been replaced by bundles of prehensile drills. Eventually she merges with Kasumi's Borg.
- Bookworm: Ever since she was in elementary school, she has collected a huge variety of books and has a dedicated room for them in her apartment.
- Brainy Brunette: She's well-versed in scientific knowledge, writing, editing, and recently accounting. All of this is partially to support her mother, and partially out of a need to expand her knowledge base.
- Came Back Wrong
- Dead Person Impersonation: Her Borg uses what remains of Kumi's corpse as a host body. As Borgs need to fuse with a human to survive longer than one year, the resurrected Kumi starts searching for a new host in fear of dying herself.
- Deuteragonist: Yuri is cited as the lead heroine in Alien 9, but it wouldn't be a stretch to say that Kumi shares that role too. Many plot points in both the main and extra chapters center around Kumi's growth as a person and the people she knows. Even her "actor" commented that the role of Kumi is meant to be support but has shades of a leading part.
- Dies Wide Open: Both anime and manga features her death this way. She lays in the wreckage of the library, eyes widened with shock.
- Early Installment Character-Design Difference: She had black eyes but later on they're green. She also had light brown hair but it becomes dark brown and later on regular brown.
- Humanoid Abomination: After her resurrection. The only thing that is human is her head. The rest is all Borg drills, making her true appearance resemble something akin to an octopus.
- Knight in Sour Armor: She is one of the most capable girls in the group, but she has very little patience for both aliens and teammates who don't pull their weight. Yuri especially gets on her nerves. Her enthusiasm in getting rid of the leftover Lynax goes against her professional attitude towards the Alien Party, something that Yuri picks up on.
- Killed Off for Real: Her original body. Her resurrected self is basically her Borg assuming her appearance.
- Killed Offscreen: While we see the events after and immediately before Kumi's death, we don't see the actual act of her dying in both the anime and the manga.
- One Sided Rivalry: Over the course of the second half of the series, it becomes increasingly obvious that Kumi is fluctuating between protectiveness and a crush towards Yuri. By Emulators, she becomes jealous of Hideaki Masumoto, a boy in Yuri's class who she bonded with after they both got kidnapped by previous gen Drills. Masumoto doesn't know a thing about Kumi's feelings.
- Quit Your Whining: Yuri's reluctance to anything involving aliens gives Kumi a migraine every time she confronts the girl. Once in a while she will unload on poor Yuri, telling her that the aliens aren't that difficult to deal with and to get over herself. She only stops doing this so often when she gets a peek into Yuri's head and discovers the terror she has to live with from her perspective.
- Red Oni, Blue Oni: Blue to Kasumi's Red.
- Sugar-and-Ice Personality: She goes hard when she wants to be hard, but there's still a young girl underneath her exterior and it doesn't take much prompting from Yuri to find it.
- Team Mom: The nagging yet nurturing kind. She doesn't have to watch out for Kasumi, but she constantly mother hens Yuri as the least experienced of the team. This is especially notable as Kumi is actually the youngest of the team, while Yuri is the oldest. When Yuri mentally regresses after losing her Borg, she latches onto Kumi because of this.
- Playing Against Type: Tsukasa Goto (who "plays" Kumi in-universe) mentions that her role as Kumi went against her usual typecasting as the lead heroine, but the trope is downplayed since Kumi is a very active character regardless.
- Tomato in the Mirror: The resurrected Kumi isn't even the real one but rather her Borg assuming her form via her memories. She often wonders how much of her still retains her humanity after the Forest of Spaceships.
- Took a Level in Jerkass: Since her resurrection.
- Was Once a Man: Originally human, now a Borg.
- We Can Rebuild Him: Upon death, Kumi was as dead as can be, having her entire stomach and several surrounding organs blown out of her body. Hisakawa dumps her into a container with "Cell Gel" in order to revive her and replace her organs. Her Borg was the finishing touch, fusing with her to resurrect her ahead of time.
- The Worm That Walks: Since her resurrection, everything save for her head is nothing but Borg drills.
Kasumi Tomine
- Voiced by: Noriko Shitaya (JP), Jessica Calvello (EN)
The Alien Party representative of the Peach Class.
Tropes associated with Kasumi:
- Aloof Older Brother: Her older brother, who she adores, is currently studying in America. Going by her comments in the Yellowknife, it seems she really misses the young man.
- Big Ol' Eyebrows: She had perfectly normal eyebrows before Chapter 11, but after fusing with the Yellowknife they've grown thicker and squatter. The end of the manga reveals that Kasumi's "actor" Satiko Oda has them naturally, and she had to shave them for the early series.
- Blood Knight: She's the most excited to be in the field, and many fights show her to be elated when she gets to beat up on aliens. It only gets worse in the second half of the story, where she tears apart aliens with relative ease all with a wide eyed grin on her face.
- Body Horror: Since her fusion with the Yellowknife, her new eyebrow "spawn" yellow knife pods in a vat of milk in her room. Then there's the fact that if she continues to fuse with it then her Yellowknife antennae will no longer spawn from her hair but instead burst from her skin.
- Boisterous Bruiser: She has no shortage of confidence as she fights, smiling all the while and incorporating flashy techniques into her style.
- Broken Ace: She's an expert at piano, ballet, chess, robotics competitions and roller skating, but her greatest fear is being alone ever since her brother left.
- Dance Battler: Some of her fighting style is taken from hobbies she's had over the years. She's shown to incorporate pirouettes when she fought one of the Sunflower class boys.
- Early Installment Character-Design Difference: In Volume 1, she had blonde hair, whilst from volume 2 and onwards she has light brown.
- Full-Frontal Assault: OVA only. In the manga, she's fully clothed when she attacks Kumi after coming out of the Yellowknife.
- Girly Bruiser: She dresses the most feminine out of the three main girls, has her Borg decked out in ribbons as well, and has performed a number of feminine hobbies in the past. She's also one of the best physical fighters in the group and loves going up against aliens with melee weapons.
- Half-Human Hybrid: After the Yellowknife mutation, she is this.
- Hive Queen: By the time she's in her 20s, she's become the queen to a Yellowknife colony she made herself. She also rounded up any Yellowknife fusions to her side in middle school.
- I Want My Beloved to Be Happy: She really appreciates Kumi and wants her to be happy, so she does everything in her power to protect her and make sure that Kumi gets what she wants.
- Jumped at the Call: Kumi also accepted going into the Alien Party, but Kasumi is the most enthusiastic about the experience. She's also the most enthusiastic about fusing with an alien, something Kumi is terrified of.
- Not Herself: After the Yellowknife mutates her, she's rather quiet unless it comes to aliens, in which she's violently fascinated and her face lights up with excitement. Yuri and especially Kumi are very wary of her behavior. She's actually sharing consciousness with the Yellowknife itself, so some of her more outlandish acts are likely attributed to it.
- Ojou: Her parents are better off than most families, and going by what hobbies they allow her to do she's brought up with a proper and elegant background. This contrasts heavily with her excitement in putting down aliens.
- Perpetual Smiler: She was always a peppy girl, with most of her appearances in the early part of the manga showing her with a huge grin. After her mutation, her default expression turns into a serious frown, but she goes back to a more manic smile whenever she's on the job.
- Pink Means Feminine: Her Alien Party gear and her Borg are shown to be a light pink in colored images and in the anime.
- Power Dyes Your Hair: Her hair turns from blonde to brown as a result of the Yellowknife mutation in volume 2.
- Red Eyes, Take Warning: Anime Only. She's perfectly fine in the early volumes, but a force to be reckoned with after she emerges from the Yellowknife.
- Red Oni, Blue Oni: The Red to Kumi's Blue. Her enthusiasm for all things alien and her more rambunctious personality contrast with Kumi's levelheaded and calm behavior.
- Stepford Smiler: While she is genuinely a peppy girl, she misses her brother dearly and his absence is the source of her insecurities.
- Token Evil Teammate: Becomes this starting from Volume 2.
- Unscrupulous Hero: Originally, she began as this, being the most excited to face aliens. By the second half, she's evolved into a:
- Nominal Hero: With her newfound fulfillment and knowing she isn't alone, Kasumi becomes a very brutal fighter. She often kills the aliens she deals with when such force isn't necessary, an takes pride in doing so.
- Verbal Tic: "Nya!" The English manga accidentally changes this to "Grin" because of a translation error, and then switches to "Nyeow" by Emulators.
- Wingding Eyes: When she's herself, her eyes are normal. When the Yellowknife takes control of Kasumi's body, her pupils become an amorphous shape much like the Yellowknife's.
- You Are Not Alone: She used to feel lonely inside because her brother was away, but she eventually gains fulfillment when she fuses with the Yellowknife and finds solidarity with the resurrected Kumi.
- You Remind Me of X: Kasumi is instantly captivated by the Yellowknife because its scent reminds her of her older brother. This captivation leads her into being swallowed by it.
Megumi Hisakawa
- Voiced by: Aya Hisakawa
- Big Damn Heroes: Kills the Sunflower alien controlling Yuri in Volume 3...as a precursor to killing her under orders, subverting this.
- Horrible Judge of Character: She doesn't really want to investigate the older generation fusions around Hinode, but when she remembers that the girls are now attending that school, she happily says that they can take care of that problem no sweat. She conveniently forgets that while two of them have fused with aliens and are capable fighters, one of them is not and all of the girls have nearly died if not for timely intervention.
- It's All About Me: The most concern she shows about the girls under her charge is which one of them will help her get a successful outcome in whatever contest she's having with the other advisors in school. Yuri accidentally snapping and killing the aliens only makes her fret because she might get replaced as school advisor.
- Laser-Guided Karma: After all the snooping around and shadiness without having to suffer any personal consequences, Emulators chapter 3 gives her a rude awakening when Kasumi isolates and kills her Borg.
- Mission Control: In the original series, she gives the girls their daily assignments, debriefs them on possible dangers, and provides them with aliens to assist them.
- No Sympathy: She does not give one crap about the girls' emotional states. Once she sees Yuri in the aftermath of killing every alien in the containment area, Hisakawa walks right past the girl with an awkward smile and laments the sorry tongue lashing she's going to get for failing her mission.
- Prehensile Hair: Revealed in Chapter 4. She can use her hair as extra arms, and in a mundane case, wrap her hair around itself before she goes to sleep. This is foreshadowing to the fact that she's already fused with an alien.
- Roaring Rampage of Revenge: She is not happy that Kasumi killed her Borg. Using "protecting the children" as an excuse, she steals Okada's Borg to go enact some unholy payback on the Yellowknife inside of her.
- Treacherous Advisor: She was never truly on the girls' side at all; she sends the aliens down to fight them, although she softballs it somewhat to build up their physical resistance to the aliens to come.
- Womanchild: Only becomes more apparent towards the end of the series and in the other installments. She may look collected in front of the girls, but she's surprisingly self-centered, immature, and throws violent tantrums when crossed.Monami: Are you sure you're a teacher?!
- Would Hurt a Child: She's perfectly willing to kill Yuri if it means stopping the source of the current Sunflower outbreak. She's only stopped from doing so by Kumi. She's also willing to hit Monami to get her to kill Kasumi as vengeance for the Yellowknife killing her Borg, and when Monami doesn't, stabs Kasumi herself (again, she only stopped from killing her by Monami).
Principal Okada
- Sweet Tooth: Many of her appearances have her chowing down on something sweet during meetings with Hisakawa.
Miyu Tamaki
Yuri's schoolmate and friend.
- Best Friend: Serves as Yuri's last remaining link to a normal life, complete with regular kid worries.
Camellia Class Boys
Hiroshi Iwanami, Manabu Namiki, and Tomoya Hironaka
Three boys from Yuri's Camellia class who follow her on duty. They each found a Gladius alien and proceeded to attack her with it.- Flat Character: While they don't have much of a role in story, they also have one trait beyond loving aliens. Iwanami likes to play the trumpet, Namiki likes techno music, and Hironaka likes to eat food.
- Easily Forgiven: There are no hard feelings whatsoever once they've been subdued. Later appearances have them (particularly Namiki) on neutral-to-decent terms with the main trio in middle school.
- I Just Want to Be Special: They all love the idea of fighting with aliens, and are jealous of Yuri for being in the Alien Party (although curiously none of them volunteered to begin with). Despite being defeated and having their Gladiuses confiscated from them, they can't shake the desire to wear them again. Downplayed as addiction is one of the Gladius' side effects.
- Personality Blood Types: It's specifically noted that all three boys have B-type blood. Some of the personality types associated with the B blood types are unpredictability, curiosity, and a flair for adventure, which is perfect for three boys who want to clash with aliens.
- Stalker without a Crush: All three boys aim for Yuri after getting their Gladiuses, waiting until she's isolated to spring an attack on her.
Hideki Takeda
A boy from the Wisteria class who has a crush on Kumi.
- Abhorrent Admirer: It's debatable if Kumi even recognizes that Hideki has a crush on her until the end of Special Plan 2, but otherwise she can't stand to be near him and hates how passive he is.
- Asshole Victim: Sure he kidnapped Yuri out of petty jealousy, but did he really deserve getting permanent damage after using the Aggressor? Notably, he is one of the only kids, besides the main trio, who sustain any permanent effects from using aliens.
- Crazy Jealous Guy: Originally a harmless, if shy young boy, he eventually steals a highly aggressive alien and uses it to kidnap Yuri, all because she stole all of Kumi's attention after she transferred to the Alien Party.
- Got Volunteered: Yet another thing he shares with Yuri. There are two reasons why he decided to share the class president role with Kumi: because he has a crush on her, and because the class keeps voting him into the position and he's too shy to decline.
- Spear Counterpart: Or rather, the other way around. His passiveness, inability to turn down opportunities forced on him, and his shy nature make him out to be basically a male Yuri. He is the reason why Kumi hates Yuri in the beginning of the manga.
- Stalker with a Crush: After Kumi opts out of being Class President to be in the Alien Party, he starts stalking her and Yuri.
Emulators characters
Monami Komai
A third year student at Hinode Junior High School.
- Color-Coded Characters: Just as the main girls have their distinct colors on their uniform, so does Monami. Her gear is accented with blue.
- Petite Pride: In the song she sings in the final chapter of Emulators, she sings about "flat chests [making] the world go round" for the first verse.
- Sixth Ranger: Treated like this for the former Alien Party.
- Start My Own: After she graduates from secondary education, Monami starts up a small alien hunting business roaming around Japan. Yuri eventually gets roped into working with her.
Hideaki Matsumoto
A boy who got captured alongside Yuri by the previous generation Drill Clan fusions.
Aliens
Drill Clan Aliens
Overall
- Lesser of Two Evils: More like multiple evils. The Drill Clan wants to take over Earth like any other invading alien species, but they are far and away the most successful because they at least allow their hosts time to build up the strength to fuse, and they can act completely separately as Emulators shows.
Borgs
Symbiotic aliens that are used by the Alien Party. They are frog-like in appearance with wings, worn on their human host's head like a helmet.- Alien Hair: Inverted. Despite being blatantly inhuman, the Borgs are capable of making hair that looks like regular human hair. Every human that fuses with them uses them as a wig, and every other alien species that fuses with them look like they have perfectly normal looking hair that contrasts with their unearthly appearances.
- Bizarre Sexual Dimorphism: Emulators introduces a female Borg. It's much larger than the male, doesn't look amphibian, and hides giant eggs underneath its shell unlike the hair male Borgs hide.
Gladius
Parasitic aliens that Hisakawa calls in to give the girls more of a challenge. They are found and used by three different boys in the Camellia class.- Evil Counterpart: It seems like the Gladius type aliens are this to the Borgs. Like the Borgs, Gladius types are worn on their host's head and fight for them, letting out projectiles from their mouths. Unlike the Borgs, they don't form a codependent relationship with their hosts, don't talk at all, and make their hosts want to use them again due to wearing them producing a chemical that induces addiction.
- Wake-Up Call Boss: Hisakawa's intention was to use them as a tougher enemy to get the girls better adjusted to fighting aliens. What she got out of them was more than she expected; while two of them came out alright, Yuri only ended up more traumatized and killed all of the Party's Borgs.
Aggressors
Previous Generation Drill Clan fusions
Various members of the species that used to fuse with Drill aliens. Including humanity, there have been nine generations, and eighth and lower seek to become the fabled 10th generation.- Bishōnen Line: As "generations" go by, this is the end result. Previous generations fused with aliens that looked like aliens, but they slowly start fusing with more and more humanoid aliens until the ninth is human entirely.
Yellowknife
Platypus-like beings that can control sound waves.
- Brown Note: To anyone not wearing a protective alien, Yellowknife soundwaves are enough to give humans screaming headaches. If more than one Yellowknife is around, it can become worse and knock out a whole building of people.
Sunflower Clan
Dangerous and aggressive aliens with the appearance of a bug with flowers on it.
- Hate Sink: Most aliens aren't malicious by nature or actively manipulative to their eventual hosts. The Sunflower clan, however, is smarter and far more uncaring compared to the rest. They don't care about who they fuse with or how ready the body is to adjust to them—all they care about is getting a host, and they'll tear through any number of people before they can land a successful one.
- Would Hurt a Child: By the time they get to Elementary School #9, they've slaughtered their way through twenty percent of Japan, and killed everyone from Elementary Schools 2 and 6.
The Original Borgs
A progenitor race that came before the Drill Clan. They are also distant ancestors of the Sunflower Clan. Kumi runs into them during her journey in Next.
