Kimihito Kurusu

The protagonist, host of Miia, Papi, Centorea, Suu, Meron, Rachnera, and Lala, and guinea pig for the inter-species marriage amendment to the exchange program.

  • Accidental Pervert: All the time. Though he gets beat up for it less than you'd think.
  • Affectionate Nickname: Miia calls Kimihito "Darling", Papi calls him "Husband" ("Boss" in the English manga), Centorea and Suu call him "Master", Meron calls him "Sir" ("Beloved" in the English manga), Rachnera calls him "Honey", Tionishia calls him "Sweetie", Zombina calls him "Babe", and Manako calls him "Dear." Ms. Smith calls him "Darling" too because she finds it amusing.
  • Always Save the Girl: He actually racks up a pretty surprising number of crimes all to protect the girls from random people, the government, and themselves. Assault, lying to the police, harboring an illegal alien, stealing a truck, etc. He gets away with it because for the most part Ms. Smith just doesn't care.
    • In chapter 15, he actually thinks that this has finally caught up with him, assuming that the police are after him for attacking the director, not even considering that it might actually be Rachnera they were after.
  • A Man Is Not a Virgin: Averted. The night the girls are all driven crazy with lust, he has a minor Freak Out saying he's "not ready and still a virgin" showing nervousness at the prospect of his first time.
    • He tries to insist this is actually the case when Rachnera teases him about the possibility that he's a virgin. It's blatantly obvious that he's lying.
  • Badass Normal: He quite often goes out of his way to assist and protect the girls in dealing with far less pleasant humans in incredibly impressive ways, often with a Megaton Punch.
  • Beware the Nice Ones: Perfectly civil and friendly with people he has no problem with. If you mess with his friends, however... Well, see the page picture of the Awesome Moments page.
  • Blank White Eyes: Pretty much the default setting for his eyes. The only time when you see his actual eyes are when he's shocked or being serious, which occurs more frequently as the story has progressed, though still not more often than the blank eyes.
  • Breaking the Fourth Wall: Does this in chapter 8 after Centorea says she'll protect him from the slime.
    "I haven't seen this in a while. Since chapter 4, I think?"
  • Brick Joke: His mention of having a leg fetish from an extra gets brought back up again in chapter 15. Rachnera assumes that her spider half disgusts him, and that he was only turned on from her human-like parts. He insists that she's wrong, that her legs are actually very charming, followed by "leg man" showing up by him in sparkles.
  • Celibate Hero: He is explicitly forbidden by law from starting a relationship with any of the girls living in his house, and with very little exception it's the girls who push to start one. Even during the initial "marriage" subplot, his first impulse was to turn Ms. Smith down rather than take advantage.
    • That being said, he seems to find all the girls quite attractive, and would have willingly consummated things with Miia some time ago had circumstances not intervened. Yes, they come onto him, but he has a tough time really being against it.
  • Chivalrous Pervert: Soundly averted. While he doesn't really object to the bizarre sexualized goings-on in his house, he also doesn't really react to them with perverted glee.
  • Crazy-Prepared: When Suu is on her water-absorbing (and orgasm-inducing) rampage in chapter 10 she leaps at Meron. Kimihito immediately produces a large plastic garbage bag to catch her mid-flight and contain her.
    "I really am used to this..."
  • Crouching Moron, Hidden Badass: Chapter 14 marks the second time he's laid out a grown man with one punch, both brought on by the recipient of said punch antagonizing one of the girls in some way.
  • Dude, Where's My Reward?: He just barely manages to save Suu's life and Papi calls out to him, flying in like she's going to hug him, and goes right past him to hug Suu.
    • Made even meaner by the fact that he managed to hijack the nearby racist pair's truck, get it off the bridge, and into the river below to catch Suu, in a matter of seconds.
  • Fee Fi Faux Pas: He tries very hard to avoid this. An extra in Volume 3 has him worrying about what kinds of food he can bring into the house anymore, assuming he has to stop buying chicken, chicken stock, fish, fish broth, and canned tuna due to Papi and Meron. Meron's fine with fish, as seaweed alone is not a good diet and compares fish for Mermaids to cows and pigs for Humans, and Papi is "totally okay with cannibalism".
  • Got Volunteered: Ms. Smith pretty much just dumps "problem cases" at his house. Of the girls he deals with, only Miia and Meron are actually "normal" homestays (for a given definition of the word, given the former's repeated attempts to break the rules to sleep with him and the latter's special needs due to her biology). All of the others are either chronic runaways (Papi, Lala), have past histories of violence (Centaurea, Rachnera) or just in an extremely legally problematic situation (Suu) that are left with him because of his proven ability to keep house with even difficult personalities.
  • Imagine Spot: Kimihito has one where he almost consummates his relationship with Miia, only for a SWAT team to break into his house and point guns at him. The next chapter, when they end up in a love hotel, it actually happens. And during the girls' full moon driven heat he gets one that shows what would happen if he broke down and let the girls have their way with him when they are unable to control their strength. It ain't pretty. He also recognizes Lala's overactive imagination because it was something he used to do himself when he was young.
    • Imagine Spotting: Kimihito can apparently see and makes remarks on Miia's fantasies about him.
  • Kubrick Stare: He combines his usual Blank White Eyes with Dull Eyes of Unhappiness and Hidden Eyes while looking at the Director this way after punching him out. Ignore what he's saying at the time and it'd seem like he's about to outright murder the guy. The second Miia talks to him though, he switches back to his usual cheerful Blank White Eyes look.
  • Made of Iron: Good thing too, as the guy takes a hell of a lot of physical abuse between the girls, even if they don't mean to hurt him.
  • Meaningful Name: His given name can be translated to public figure. As in the guinea pig to see whether or not the interspecies marriage amendment to the Cultural Exchange Between Species Law is viable or not.
  • Megaton Punch: As shown in two separate moments, he has a mean right hook.
  • Mistaken for Racist: Because she's running off of what she heard from the director, including the false belief that he had smashed Papi's egg into the director's face rather than a chicken egg, Rachnera assumes that he's just pretending to be a decent person but actually discriminates against extraspecies.
    • The assumption is made once again by Manako, as most people are apparently never willing to directly look at her out of annoyance or fear. When he's able to look her directly in the eye she begins to panic in embarrassment.
  • Nice Guy: The driving force behind each of the girls falling in love with him, and the reason Ms. Smith keeps leaving "difficult" homestays at his house: Kimihito can get along with anyone.
  • Old Shame: In-Universe: he had a wild imagination in middle school. This helps him later in life to identify Lala's death talk as just delusions. When questioned by Ms. Smith if he was like that as well he tries to deny it.
  • Only Sane Man: As is standard with a harem-genre protagonist. Doesn't help that the only authority figure we've seen so far is little better than his harem.
  • Real Men Wear Pink: He enjoys cooking, cleaning, and sewing. His skills are useful when the monster girls get clothes that need adjusting.
  • Rescue Romance: So far he has, at least once, ended up rescuing or protecting each member of his harem. Each time either being what caused them to fall for him or, in the event that they already had, to display their affection much more openly.
  • Supreme Chef: He's described as a very good chef by Smith in chapter 17, though we don't get to see any of the things he makes until chaper 25.
  • Taking the Bullet:
    • Kimihito takes an attack from a fake sword meant for Centorea.
    • He also takes three tranquilizer bullets in chapter 5, when he jumps in front of the girls.
  • Tempting Fate: In Chapter 24 he says several things in rapid succession that get called Death Flags in order to disprove Lala's claims.
    Kimihito: "You guys are way too gullible!... In the first place that girl's not even... hmmm... Miia If, IF I make it back alive, we're getting married! I'm not sticking around here! I'm going home! I'm not afraid of anything anymore!"
    • Screw Destiny: Immediately after this he walks out into traffic, and nothing hits him.
    Kimihito: "Got it? There's no such thing as fate! And seriously, I'm on the brink of death every single day!"
  • Unfazed Everyman: With a few exceptions, he is a largely open-minded and tolerant individual who takes the many bizarre things that happen to him more-or-less in stride. Most of the girls find this very attractive, even when they don't live with him or fall for him.
    • Even being hooked around the neck with a scythe merely registers to him as "something was off", and he casually turns around to find out what it was about.
  • Unwilling Suspension: Rachnera does this to him twice. Once while he was unconscious, letting him down when he mentions the blood flowing into his head, and again shortly after, rigging the webbing so that if he spit out her webbing he'd fall.
  • Your Days Are Numbered: Lala arrived to inform him that he's currently on the brink of death. He's fully aware of it, as he's on the brink of death daily. He's also aware it's just an act, and that she's not really a grim reaper, just a silly dullahan with a wild imagination.

Ms. Smith

Kimihito's cultural exchange coordinator. Rather lazy when it comes to her job, yet she still seems to have no problem dumping girls off on Kimihito and using him as a guinea pig for amendments to the exchange program's rules.

  • A Day in the Limelight: Chapter 11 is focused on her and her Special Forces Squad.
  • Beleaguered Bureaucrat: The reason she's so lazy and irresponsible is because her job is a rotten combination of demanding and thankless.
  • Beware the Silly Ones: She may be a bum at times, but she's absolutely terrifying when she suspects someone's breaking the rules or threatening to harm someone.
  • Cool Shades: To go with her traditional government agent's uniform.
  • Dull Eyes of Unhappiness: When the glasses come off and she's exceptionally pissed off at the last orc still standing in Chapter 11.
  • Dynamic Entry: Fond of these, whether it's kicking down a love hotel door or jumping through Kimihito's bedroom window.
    • Your Door Was Open: Perhaps just as often she has a tendency to simply appear without warning or explanation, notably in the first chapter where the reveal that she's present startles Kimihito and again showing up suddenly among the rest of MON in Chapter 11.
  • Fashionable Asymmetry: In the very beginning her bangs cover one eye just short of Peek-a-Bangs. The Art quickly evolves, however, and she's currently symmetrical.
  • The Glasses Come Off: When she's off duty. Or hurting someone.
  • Idiot Houdini: Kimihito suffers no end due to her irresponsibility, and she never suffers for it.
    • This finally backfires on her in chapter 13. She left her coworkers to cover her at work while saying it was to keep the other girls away from Kurusu while ill to avoid a viral mutation, when in fact she just wanted to slack off. Once she catches his cold, her coworkers refuse to help her for the same reason she gave them.
  • The Lad-ette: She's grossly irresponsible at her job, constantly bums off Kimihito for meals, and her own apartment's a sty.
  • Last Name Basis: With most of the cast, even though she does interact with them non-professionally.
  • Must Have Caffeine: Coffee, specifically Kimihito's coffee, is more or less her Trademark Favorite Food. The cheap instant coffee during a meeting is regarded as awful, the cheap instant coffee at his house the best.
  • Reasonable Authority Figure: Hell no, a huge part of Kimihito's problems comes from how irresponsible she is.
  • Screw the Rules, I'm Doing What's Right: "Doppel" stays behind with the orc leader to "punish" him for making her job harder, while Doppel leaves as her.
  • She's Got Legs: Hoo boy, does she ever. She even lampshades it when Kimihito reveals he has a leg fetish in an extra chapter.
  • Slasher Smile: Sports a small, but very ominous, one when dealing with the orc leader.
  • Spell My Name with an S: Her name was mistranslated in the first chapter as "Sumike" in the fan translation, most probably due to the translator confusing the katakana for ke (ケ) with that for su (ス).
  • Token Human: She's the only known human member for MON, though the nature of the group leaves her to typically just be the face of the group while the extraspecies members handle the work.
  • Victoria's Secret Compartment: For her tranquilizer gun.

The Racist Couple

The Those Two Guys of the series, a pair of grade-A Jerkasses who tends to show up from time to time, mostly appearing wherever Kimihito and the girls are appearing.

  • Asshole Victim: When they first insult Miia, she tries to attack them, but Kimihito intercepts the attack due to the rule of humans and non-humans attacking each other. Later when they show up again and insult her again, he punches both of them rather hard, injuring his hand in the process.
  • Dark-Skinned Blond: The girl looks like a ganguro.
  • Fantastic Racism: Pretty much all they do is throw bigoted insults at the monster girls just for the sake of messing with them.
  • Gang Bangers: The man in the couple seems to be one of these.
  • Gonk: Look at all the other humans. Look at all the other monster girls. Now look at them.
  • Jerkass: They don't limit their dickery to monster girls; other humans are also targeted by their harassment.
  • Laser-Guided Karma: Whenever they show up, expect something bad to happen to them very soon.
  • Shoo Out the Clowns: They were effectively Put on a Bus when the manga began its Cerebus Syndrome, though they later reappear in an Imagine Spot.
  • Those Two Guys: "Randomly show up to give the main characters grief" pretty much sums up their role.

Kunanzuki Ren

The daughter of Rachnera's first host family, she tried to adopt Rachnera back into her family.

  • The Atoner: She wanted to readopt Rachnera out of guilt for her parents selling her.
  • Innocently Insensitive: She has a bad habit of insulting people without actively trying to. Kimihito even refused to let her adopt Rachnera because she kept treating Rachnera like a challenge to overcome instead of an actual person.
  • Turn the Other Cheek: Her response to everything that happens to her is to bring on the next challenge, such as repeatedly eating Miia's latest dish despite passing out each time.

    Monster Girls Living With Kimihito 

In General
  • A Dog Named Dog: The names are all indicators of their species.
  • Because You Were Nice to Me: Each of the girls, aside from Lala, fell in love with Kimihito by his acts of kindness:
    • Miia: The first human she met outside of the exchange program officials/agents (who don't count, as they're probably keep a strictly professional distance), whose first reaction to her was not to shun her for being a monster girl, but to be concerned about her getting cold due to her snake-like physiologynote .
    • Papi: Saved her from a fall while she rescued a child, as well as lied to a police officer that he was her host to prevent her deportation.
    • Centorea: Took a sword slash for her against a mugger while she was unarmed and stunned.
    • Suu: Despite appearing out of nowhere, cared for her as one of his own, even going as far as saving her from a rainstorm.
    • Meron: Saved her from her runaway wheelchair as well as a moisture-hungry Suu, all before she revealed herself as a mermaid and his newest resident.
    • Rachnera: Treated her like a normal girl, in spite of her appearance, and refused to assume the worst of her in a very dangerous situation.
  • Cute Monster Girl: Duh.
  • Does Not Know Her Own Strength: Miia tends to strangle or constrict Kimihito to the breaking point by accident. Kimihito even reacts to her friendly pats on the back like he's getting punched. And when Lunacy strikes Miia, Papi and Centorea, all at the same time, they all suffer from this, thus leaving Kimihito facing a very real risk of literally getting killed during intercourse if the temporarily lust-crazed girls manage to capture him long enough to have their way with him.
  • Foil: Miia and Meron, Papi and Suu, and Centorea and Rachnera. This gets played up in the various date chapters.
  • My Significance Sense Is Tingling: When Rachnera arranges to move in, it cuts back to the house showing Miia, Centorea, Meron, and Suu looking horrified, and the first three all thinking "I just got the feeling another rival is about to show up...". Papi, as usual, seems to either not notice or not care.
  • No Sense of Personal Space: Oh so much.
  • Spell My Name with an S: It's... a little complicated.
    • At first, Miia, Centorea, and Suu's names have been romanized as "Miia", "Centorea", and "Suu" by the fan-translator.
    • Then came Chapter 10, where the cover image revealed that the author apparently intended for the names to be romanized as "Meer" note , "Centaurea", and "Sue". (Papi is still romanized as "Papi", BTW)
    • However, the fan translator insists on adhering to the "Miia" spelling because they consider the official one to be a "terrible" choice as 1) it's a boy's name... in Hindi; and 2) for some reason they believe that it's too much of a stretch to get "Miia" (the romaji form) out of "Miia".
    • From there, it appears the fan-translator decided that it would unfair/inconsistent to make an exception for her alone, and thus all three are still referred to as "Miia", "Centorea" and "Suu" in the fan translation.
    • Finally, Volume 1 of the manga got an official English translation, in which the names are spelled "Miia" and "Centorea," and Volume 2 has "Suu" and, adding in another example, "Meroune Lorelei" as "Meron Lorelei".
  • The Three Faces of Eve: Of the three girls who are in love with Kimihito, Papi is the Child because she is joyous, absent-minded, and a bit naive; Centorea is the Wife because she is incredibly honorable and chivalrous, as well as unerringly loyal to Kimihito; and Miia is the Seductress because she is very flirtatious, trying to seduce Kimihito on multiple occasions. They do however occasionally take on other aspects, and as the harem grows and they start trying to compete pinning one trait to any one of them becomes pretty much impossible.


Miia is a lamia and the first girl that Ms. Smith just dumped off on Kimihito. It didn't take long for her to fall in love with him and she has little problem turning on the charm to try to get him to make a move.

  • Bare Your Midriff: Not to the extent as Meron, but she finds a way to do this pretty often: she's outwardly stated that her waist is her best feature.
  • Blatant Lies: Claims that the Homestay Rules clearly state that the first girl to begin their stay at a home has privilege, basically saying she has officially-sanctioned first dibs on Kimihito. Nobody buys it.
  • Clingy Jealous Girl: Once Papi and Centorea move in. It gets worse with each new "rival".
  • Cuddle Bug: Much to Kimihito's dismay she tends to forget to hold back her strength.
  • Cute Little Fangs: Really prominent when her cuteness factor is high.
  • Does Not Know Her Own Strength: As noted, she tends to forget a little restraint. You could make a drinking game of the number of times Kimihito has been accidentally hurt by her.
  • Extreme Omnivore: She can eat her own cooking without any negative effects.
  • Fangirl: Of the Metal Gear series, if her frequent cosplays as Solid and Naked Snake are any indication.
  • Fantastic Arousal: Her tail, specifically the tip. She was also very clearly aroused when Kimihito helped peel her scales off when she was shedding. The first chapter has Kimihito accidentally do this in an attempt to get her off him.
  • Fiery Redhead: The most passionate and romantic of the girls, and the only redhead.
  • First Girl Wins: While nothing has been set in stone, she is the favorite of both the majority of the fanbase and the author, and she's the most open to Darling. Really, it's more that she's built up to be the winner enough that her not winning would seem more contrived.
    • She invokes this herself to the other guests (see Blatant Lies above).
    • This seems to be the case as of Chapter 24, with Kimihito telling her if he survives he's going to marry her. It was most likely not serious, as it gets pointed out immediately after he's saying multiple things in rapid succession that are all Death Flags.
  • Freakiness Shame: She shows embarrassment when Kimihito sees her shedding. "Darling" tells her A) it's natural for her to shed and B) he's already seen her naked and this is less embarrassing for both than that (except it's not as lamia find being seen shedding far more embarrassing than nudity).
  • Girly Bruiser: Well, considering that she's an extraspecies, the incredible strength is a given. Miia however has proven herself to be capable at climbing trees, and judging by a couple of scenes where she goes into stances before a fight she apparently knows some manner of martial art. She's even a capable enough swimmer to keep up with a mermaid, though that was very reliant on clever tricks rather than pure athleticism.
  • Hellish Pupils: She has slitted snake pupils, a normal trait for lamiae, though it becomes much more prominent when she's mad — or really deep in full moon-induced lust.
  • Hoist by His Own Petard: Drastically lowers the temperature of the room she's currently in to try making Meron uncomfortable. She's the only one who has any issues with cold. Papi and Centorea aren't sure if she was going to kill herself or just end up hibernating, but Kimihito fixes the temperature before they can find out.
  • Hot-Blooded: Despite being physically cold-blooded, she's extremely passionate in what she does (i.e. wooing Kimihito). Ms. Smith even mentions it's a trait with lamiae.
  • Imagine Spot: Miia does this a lot, but the one in Chapter 3, where she remembers an event in the previous chapter but modifies Kimihito into a Hot-Blooded and Bad Ass hero complete with Hand Wraps Of Awesome, probably takes the cake.
  • Immodest Orgasm: And before you're even ten pages into the story, too.
  • Lethal Chef:
    • She's never studied cooking in her life; Kimihito, Papi and Centorea find this out the hard way when Miia, trying to "teach" herself how to cook (by "emulating" what she saw from Kimihito's own cookwork in the kitchen), tests her culinary creations on Papi and Centorea, and incapacitates them for an entire chapter! Kimihito initially assumes that the food she made was traditional lamiae cuisine and ate it all.
    • In chapter 13, Meron eats some of her food, and the taste brings to her mind the idea of how it would feel to have her fins torn apart. (In context, it's a reference to the Sea Witch's potion in Little Mermaid, which is what Meron's subconscious opinion of the meal is - i.e it's a incredibly dangerous, painful concoction you probably shouldn't put into your mouth.)
    • Chapter 25 provides an explanation for Miia's horrible cooking: as a carnivore, Miia's sense of taste is far less sensitive than a human's, making it difficult for her to judge the quality of her cooking.
      • Miia's inability to taste food is further compounded by her incredible lack of judgment in cooking. Her recipe for white rice gruel includes things such as white peach, white icefish, and white chocolate (in other words, ingredients chosen simply because they were white)! And more recently, she added peanut butter to miso soup on the basis that she thinks it looks like miso.
  • Logical Weakness: As mentioned in chapter 1, her being part-reptile makes her susceptible to cold temperatures, and she requires warmth to stay healthy. Even in a heated swimming pool, over time she'll become sluggish.
  • Loveable Sex Maniac: She really wants to get into Kimihito's pants. She even tried to strip Kimihito while he's sick!
  • Marshmallow Hell: Really likes doing this to Kimihito.
  • Nightmare Face: Played for laughs: Miia decides to take the initiative saving a kid stuck in a tree in order to impress Kimihito and show up Papi. Unfortunately, when she got to the top, the first thing the kid saw were a pair of Hellish Pupils, vicious looking fangs and long nails peeking through the leaves.
    Miia: "Found you."
    • Another instance in Chapter 6. Considering the context, it was probably meant to come across as "sexy" rather than "scary". But Miia's sudden reveal of her Overly-Long Tongue while she's under the effect of Lunacy could come across as this, particularly as the panel puts her mere inches from the reader.
  • Our Nudity Is Different: Witnessing a lamia shedding her skin is far more embarrassing than simple nudity.
  • Overly-Long Tongue: She wouldn't be a snake without one. Interesting to note that it's a human tongue, not a reptilian one.
  • Pointed Ears: Just one more bit of divergence from the human body type.
  • Snake People: Duh.
  • Snakes Are Sexy: And she exploits it for all it's worth.
  • Super Strength: She can crumple steel in her coils with virtually no effort, often without even realizing it. Justified assuming that unlike a snake, all her major organs are probably up in her human half, making her tail a huge mass of solid muscle and bone.
  • The Tease: It becomes clear very quickly that she doesn't give a crap about the no sex rule of the exchange program as she tries seducing Kimihito fairly regularly.
    • She once outright stated, while laying naked on the bed, that she wants him to take her virginity.
    • Chapter 2 has her gleefully pulling Kimihito into a lingerie shop and taking off her top in front of him, asking his opinion on the bras, and dragging him towards the changing rooms with her. All with a smile on her face.
  • Tsundere: Type B. She's sugary-sweet to Kimihito, but she can be violent when provoked (especially by romantic competition, i.e. Papi and Centorea).
  • Weaksauce Weakness: Cold. Justified as she's a lamia, i.e. a reptile. It's also dangerous for her to be in large bodies of water for this reason; while she can swim quite well, it's harder to maintain her body temperature in a pool, even if it's a heated one.
  • Why Did It Have To Be Severed Heads: Miia does not react well to Dullahan.
  • Your Size May Vary: The length of her tail, which varies from being several feet long to closer to twenty feet, though according to Chapter 17 her body is eight meters (just over twenty-six feet) long in total.


A harpy and the second girl to end up living with Kimihito. She's childish, both physically and mentally, despite being as old as Miia.

  • Absurdly Sharp Claws: The talons on her feet are like butcher knives.
  • Accidental Truth: When she was first introduced she mentioned that she was informed that if she kept flying away she was going to get "deflowered". A few chapters later she, with the help of Miia and Centorea, runs off with Suu who proceeds to do just that to the three of them.
    • The setup for this is not present in the official English version, mistaking deported as aborted rather than deflowered.
  • Adult Fear: She watches the girl she saved early in the series get run over by a truck, who was only saved because Suu managed to wrap her up and absorb the force of the impact. Before they can get Suu unstuck from the side of the bridge they were on, it collapses dropping her into the river and because of her hands not being strong enough to hold people and Suu being slippery she can't do anything but watch her fall.
  • Ambiguously Bi: In addition to her relationship with Suu, sucking on Kii's breasts is the first solution to depowering her that comes to Papi's mind. That said she is openly in love with Kimihito.
  • Attention Deficit... Ooh, Shiny!: After kidnapping Kimihito, she asks him to get some food. As they walk there, she immediately forgets who he was.
  • Big Sister Instinct: She's rather protective of Suu, even flying off with her when the others think about giving her up.
    • Mama Bear: It's noted that her motherly instincts are really strong. She ends up switching between the two depending on the situation.
  • The Ditz: Has a short attention span that lasts for mere seconds. The few things she does remember are usually misremembered.
    • She also tends to focus on completely random minor details. While watching a news report on a hostage situation and how it'll be affecting the Extraspecies Exchange Laws, Miia and Centorea discuss that. Papi on the other hand.
      Papi: "Huh? Isn't that Ms. Smith?... That is Ms. Smith."
  • Femme Fatalons: Her wings have exposed thumbs like a bat each ending in a sharp black claw.
  • Harping On About Harpies: Of course.
  • Heterosexual Life-Partners: After Suu starts living at Kimihito's house, the two of them are rarely seen without the other; she even spends the majority of Chapter 12 trying to find Suu rather than deal with anything else that's going on. The pair are often seen providing various Funny Background Events while ignoring the drama from the other girls.
  • Idiot Hair: ...Well, as unkind as it might be to be blunt about it…
  • Immodest Orgasm: Papi has one when Suu gets too touchy with her after she gets wet. She also has one when Kii wraps her bondage-style in vines and tightens them.
  • Innocent Fanservice Girl: Papi has no concept of modesty, as she dives into a public fountain naked thinking it's a bird bath.
    • Ambiguous Innocence: As Centorea points out, she's nowhere near as young as she looks, and is never above trying to use her apparent naivete as an excuse to jump Kimihito.
  • Logical Weakness: If her wings are too wet, she becomes unable to fly.
  • Older than They Look: Harpies look like young teenagers even as adults for the sake of flight. In reality, she's just as old as Miia, which the latter doesn't take too well when Papi drags Kimihito into the bath together.
  • Perpetual Molt: She tends to drop feathers whenever she takes flight.
  • Solid Gold Poop: Harpies are known, at least by their species, to lay unfertilized eggs from time to time. Said eggs are worth 3 MILLION yen on the black market.
  • Third-Person Person: Delves into this sometimes, like when she first introduces herself.
    Papi: Papi's a harpy is what Papi is!
  • Too Kinky to Torture: Rachnee wanted to play "games" with Suu and Papi while the others were at the health club, but apparently the end result is Rachnee exhausted and Suu and Papi happily swinging around in arachne webs.
  • Who Wears Short Shorts?: People whose legs would make pants difficult.
  • Winged Humanoid: The "wings-for-forelimbs" variation, but the digits of her wingsnote  are somewhat more human finger-like, and thus allow her to hold objects in them, as demonstrated when she was shown holding the Wii Remote in her hand to play with Kimihito's Nintendo Wii. She's not as dexterous with them as humans are with their own hands/fingers, though; she has trouble holding on to an ice cream cone properly, for example.
  • You Gotta Have Blue Hair: With matching blue feathers, too.

Centorea Shianus

A centaur and the third girl to move in with Kimihito. Very prim and proper, as expected from a self-proclaimed knight.

  • Above the Influence: Holds out longer than anyone else once the full moon puts all the girls into a mating frenzy... but the key word there is "longer." In fact, she holds out long enough to tell Kimihito of the moon's effects, before immediately succumbing to them afterward.
  • Absurdly Sharp Blade: By most standards, not really as it's a fake sword. But she's skilled enough that it's sharp enough to slice through several barrels effortlessly and later a door. A criminal who got a hold of it was able to inflict considerable, but nonlethal, damage to Kimihito.
  • Adorkable: No, seriously. She has her moments. Just look at her expression when she first holds hands with Kimihito, or giving a Headbutt Thermometer to Kimihito!Suu.
  • Affectionate Nickname: Only those close to her can call her "Cerea," which Kimihito does.
  • Big Eater: She usually manages to keep her appetite in check, but if she eats something she really enjoys, she'll gorge herself with reckless abandon. This got the entire group banned from a restaurant once.
  • Clingy Jealous Girl: She may think of it as beneath her, but deep down she's just as clingy to Kimihito as much as Miia is. This comes to the forefront in Chapter 16.
  • Courtly Love: Since she thinks of herself as a knight, she tends to think of her relationship with Kurusu along these lines: she loves him, but expressing that love or pursuing him would be un-knightly.
  • Crash into Hello: Centorea's introduction. She immediately declares that it means Kimihito is her "fated master", because a charm said so (he just recognized it as a manga stock scene) She also wonders if she should have put toast in her mouth beforehand.
  • Cute Clumsy Girl: Though usually quite coordinated, Centorea becomes very clumsy and accident prone when she's feeling nervous or shy. The fact that her enormous hindquarters tend to smash into things can be a problem.
  • Expressive Ears: In chapter 25 they wriggle as she was eating carrots given to her.
  • Gag Boobs: They're massive (a 103 I bra was tried and found too small) and quite prone to gags like Thanks For The Mammaries or Marshmallow Hell. The huge size is justified as it's a racial trait to compensate for the fact that centaur babies are bigger than most and require a lot more nourishment. note 
    • Thanks For The Mammaries: Pretty regularly, especially whenever Kimihito has to hitch a ride and needs a place to... hold on.
  • Gamer Chick: While she hasn't been seen playing games yet, she does admit that her knowledge of many obscure non-human races is heavily informed by video games, such as slimes and dullahan.
  • Going Commando: She does not wear panties or a bra because it's a centaur custom, and also because it'd be very difficult to wear panties given the unusual shape of her hindquarters.
  • High-Pressure Emotion: Prone to these in extreme embarrassment, complete with steam billowing off her head. She's also hot enough to burn a table with her body temp.
  • Keigo: Rendered by scanlations into Ye Olde Butcherede Englishe. It's been dialed back a bit since her introduction, but returns when she's feeling nervous in Chapter 21.
  • Large Ham: Has a habit of being melodramatic. She even compares her meeting with Kimihito to the meeting of Hercules and Chiron.
  • My Friends... and Zoidberg: Miia draws up a diagram explaining everyone's connections when they think the government is after Suu. Centorea's place on this is simply marked as "?".
  • Occidental Otaku: A lot of her assumptions on how things in Japan work are based on anime, manga, and video games. Her room is even designed in a traditional Japanese fashion, complete with tatami mats, in contrast to the rest of Kimihito's modern home.
  • One-Note Cook:
    • Cerea, unlike Miia, actually does know how to cook. Unfortunately, it's centaur food, which is large amounts of mostly-raw vegetables. It's very healthy and filling, but also rather bland.
    • In chapter 25 it is revealed that being a herbivore, her sense of taste is 2-4 times more sensitive than a human's, which could justify her food in chapter 21 being rather bland to non-herbivores like Kimihito and Rachnera.
  • Only Sane Woman: In Chapter 12, she more or less spends the entirety of Miia's jealous rampage pointing out just how crazy she's acting. In general, she's the reasonable girl of the lot, who doesn't try to push Kimihito around as much as the others.
  • Phenotype Stereotype: Blonde-haired, blue-eyed girl? Check. Foreigner? Check (she's most likely from Europe given her knightly background).
  • Proud Warrior Race Girl: The centaur race in general going by her stories of centaur knighthood.
  • Token Wholesome: Centorea actually dresses and acts very properly. It's just that being stacked like a snow fort makes modesty... difficult.
  • Wrong Genre Savvy: Slimes are not the easiest things to kill despite what RPGs have told her, much to her disappointment. Later, she assumes "D" might be a "devil," and shows up to her date in full plate armor ready for a fight. When she does encounter a devil on her date, it isn't "D", and it isn't what she expected either.


A slime girl who just randomly showed up one night at Kimihito's house. She seems to mostly mimic the behavior of those around her.

  • Ambiguous Innocence: While she was mostly unaware of right and wrong at first, Suu has probably figured out more of it as the series goes on, despite continuing with the tentacle rape and such. Notably, she seems to only talk with Kimihito when none of the other girls are watching.
  • Attack of the 50-Foot Whatever: After absorbing experimental chemicals she grows to kaiju proportions.
  • Bi the Way: As detailed below, she gets very touchy with other girls when water is involved. Of particular note is Papi: Suu kisses the harpy on the lips before having her way with her.
  • Bizarre Alien Biology: Volume 2 comes with an explanation of how she works. Some notable details include that she can store up to a fish tank's worth of water in her bust, her eyes store the information required for her transformations, the short feeler on her head is used for reading others' feelings, and the longer ones are used for "grabbing things, absorbing water, and performing tentacle rape."
  • Black Comedy Rape: She gets very touchy with the other girls whens she gets hungry and they get wet, to the point of inducing Immodest Orgasm. Even a drop of sweat will cause her to violate them. Her response when Draco attacks Kimihito is to go tentacle-monster on her.
  • Blob Monster: She is a slime.
  • Broken Masquerade: Prior to her appearance slimes were still considered fictional creatures and, thanks to Ms. Smith not wanting to bother, are still thought of that way outside of the people she interacts with. The other girls didn't even know humanoid slimes actually existed, which made them fictional to both worlds.
  • Dressed All in Rubber: Wears nothing more than a raincoat and boots. When she wears something.
  • Dropping the Bombshell: At the end of Chapter 13 she reveals that she can speak in more than just mimicked phrases, as well as her feelings.
    Suu: "Well, it was Suu's fault that you caught a cold... I should apologize as well. But Suu doesn't mind! Because she loves her Master!"
  • The Empath: In Chapter 13, the answer to whether or not she could read thoughts from chapter 8 is answered. She's apparently able to figure out the basic emotions of people when she puts her antenna to their forehead. Chapter 25 reveals she can also communicate her own thoughts to others this way.
  • Extreme Omnivore:
    • Capable of eating Miia's horrifying food with no ill effect. She can also absorb body fluids and liquid fertilizer.
    • Kimihito asks her to help him pick mushrooms due to this. Even after eating a few poison mushrooms, the only side effect is poisoning her speech and making the water she spews out as an attack poisonous.
  • Finger Gun: And she can spray water with it.
  • Foreshadowing: In Chapter 8, Kimihito says it would have been a bad thing had Suu absorbed too much water and grown to gigantic proportions. She does exactly this in Chapter 20.
  • Heterosexual Life-Partners: After Suu starts living at Kimihito's house, she and Papi are rarely seen without each other. The pair are often seen providing various Funny Background Events while ignoring the drama from the other girls.
  • Idiot Hair: Has an "antenna" in the shape of it. Though, unlike Papi, she's more childlike and naive than dumb.
  • Immodest Orgasm: When Kii the dryad latches roots onto her breasts, Suu has one. She's also prone to causing the other girls to have them whenever she gets thirsty.
  • Innocent Fanservice Girl: Part and parcel of being from a race without any real culture or language whose body type makes most clothes impossible.
  • Innocently Insensitive: Suu knows about as much about social norms as a newborn child. Hence the... well, look a few tropes up. Whatever brain-to-mouth filter she may possess shorts out when she ingests poisonous materials.
  • Logical Weakness:
    • As she's made entirely of some liquid-like substance, she becomes "diluted" when submerged in a bathtub-sized body of water, and takes time to reform and drag herself out of it. If she falls into a huge enough body of water (e.g. a river) or gets caught in a heavy storm, however, the dilution effect would be serious enough to kill her.
    • On the opposite side of the coin, dehydrating her shrinks her and makes her lose her humanoid form and revert to a compact blob, but doing so is akin to starving her. Most of the hijinks revolving around her involve her attacking anyone with even a trace of moisture on them.
  • Loveable Sex Maniac: While it's not specifically sex that she's after, the other girls consider her to be one and tell Rachnera to get used to being violated by her.
  • Morphic Resonance: Regardless of whether she's in blob, child, or adult form, or mimicking another person or object, she always has her antenna.
  • New Powers as the Plot Demands: Suu has done this a lot throughout the series, helped by the fact that she's a non-mythological monster without defined powers, and by the fact that hers is a new species about which little is known.
  • Obfuscating Stupidity: While no one is sure how long she's been able to, she accidentally reveals that she can speak in more than just mimicked phrases. As soon as she's called out on it, she goes back to mimicking.
    • She's also the one to put the kibosh on the Director's plans to sell Papi's egg (and more than that, her dignity) by reading his mind and broadcasting his true intentions for all to hear.
    • Chapter 20 reveals that her intelligence is based upon her size. As a blob able to fit in a bucket she's essentially just running on instinct, in her base form her intelligence is that of a child, and in kaiju form she's able to make scientific deductions based on her surroundings. Though in Chapter 25 her "child" form is still able to hold a conversation once out of sight of everyone but Kimihito, and makes rude insults when taste-testing possibly-poisonous plants has given her a "venomous" tongue.
  • The Quiet One: She doesn't talk much, though that's because she's still learning how to talk. Or is she? No one can really be sure anymore. She is fully capable of speech as of Chapter 20, though.
  • Running Gag: Her small blob form being put inside of a bucket.
  • Sexier Alter Ego: She can absorb water to make herself taller, bouncier, and curvier than usual, complete with major Breast Expansion. It also (possibly) gives her an intelligence upgrade.
  • Spell My Name with an S: The cover art for Chapter 10 spells her name as "Sue".
  • Telepathy: In addition to knowing the emotions of people she's touching, she can see their memories as well.
  • Too Kinky to Torture: Rachnee wanted to play "games" with Suu and Papi while the others were at the health club, but apparently the end result is Rachnee exhausted and Suu and Papi happily swinging around in arachne webs.
  • Voice Changeling: She can mimic a person's voice precisely depending on the persona she takes on.
  • You Gotta Have Green Hair: Well, the slime that makes up her hair anyway.
  • Your Size May Vary: Her raincoat's length seems to adjust along with her size when compared to her boots. While in her more childlike form, it looks like a Badass Longcoat. While in her adult form it's barely any larger than a shirt, despite the boots still only going up about halfway to the knees.

Meron Lorelei

A mermaid and the fourth girl to officially move in with Kimihito (Ms. Smith has, unsurprisingly, considered Suu to not be her problem). Wheelchair-bound for obvious reasons when out of the water, she first meets Kimihito when she loses control of it and he saves her. After she helps him find the other girls, it's revealed the waterproof room being built in Kimihito's house wasn't for Suu at all; instead it was so Ms. Smith could dump her off on him.

  • Adorkable: Not quite to the degree of Centorea, but Meron has her share of awkward moments, mostly her being Innocently Insensitive. Examples include when she interrupts what would have been Kimihito and Miia's first kiss with fish trivia, or when she cheerfully tries to compliment Miia by saying she "swam like an eel."
  • Bare Your Midriff: When not wearing her maid outfit, she spends most of her time around the house in a bikini top, probably so she can slip easily in and out of the pool in her room whenever she wants.
  • Be Careful What You Wish For: After seeing Kimihito and Miia's lovely date together in Chapter 19, Mero discovers the feelings of jealousy and loss—and they're not what she expected, even though she wanted it to happen.
  • Charm Person: Perhaps further hinting at her royal origins, she possesses a compelling regal aura capable of making people genuflect when speaking.
  • Covert Pervert: Doesn't really mind getting tied up by Rachnera since it feels good to her.
  • Crash into Hello: Kimihito plucks her from her runaway wheelchair and ends up smashed between her and a pole during their first encounter.
  • Everything's Better with Princesses: Maybe. Centorea and other people she meets certainly get that vibe from her, and she does seem to know an awful lot about knights and nobles.
    • Modest Royalty: In the "dresses like a commoner" sense, not in the "too modest to spend an entire chapter either in a bikini or out of it" sense.
  • Exact Words: Done during a conversation with Miia; at first it comes off as her exposing herself as a Yandere, but in retrospect is in fact her admitting she only wants second place.
    Miia: Well, anyway!! I'm going to make sure you don't get your hands on my Darling! Got it?!
    Meron: Oh, don't worry. The feeling...... Is mutual.
  • Expressive Ears: They drooped when she took a bite of Miia's cooking.
  • Innocently Insensitive: Sometimes. She's sincere in her compliments, it's just her choice of words are usually... poor.
    Meron: "There, there, Miia-sama was amazing as well. You swam just like an eel!" *totally innocent*
  • Limited Wardrobe: Says she only has her Gothic Lolita outfit to wear in chapter 23.
  • Logical Weakness: Given that mermaids breathe water, the purity of the water is important. Swimming in chlorinated water is dangerous to her health; it would be the human equivalent of breathing in bleach fumes.
  • Love Epiphany: She has one at the end of chapter 19, after Miia and Kimihito's date at the aquarium. This after claiming to only want to experience a tragic love like in The Little Mermaid.
  • Marshmallow Hell: It's what Kimihito gets after saving her from her runaway wheelchair in their first meeting.
  • Moment Killer: She accidentally does this to Miia and Kimihito in Chapter 19.
  • Nice Girl: Insensitive moments aside, she is unfailingly kind and polite to everyone she meets.
  • Nightmare Fetishist: Wants to experience a "tragic love" like in the original Little Mermaid story, including turning into sea foam! However, she doesn't enjoy actually experiencing it in chapter 19, and in Chapter 24 shifts her priorities to having Kimihito's children so that she can raise them without him.
  • Our Mermaids Are Different: Apparently they have webbed hands, fin-like ears, gills along their rib cages, and a pronounced set of pelvic fins. Also they can survive on land so long as there is a decent amount of humidity, and give off a mucus-like secretion to retain moisture.
    • Mermaid Problem: Not an issue, if her attempt to copulate with Kimihito in Chapter 24 is any indication, and in hindsight her clothes do cover the part of her body one would expect.
  • Perky Goth: Dresses in the Elegant Gothic Lolita style and is a bit of a Nightmare Fetishist, but has a very warm personality overall.
  • Rose-Haired Sweetie: Very princess-y and refined, whatever her bizarre interests.
  • Shipper on Deck: She wants anyone but herself to be with Kimihito, primarily Miia as she was the only one to openly acknowledge being interested in him.
  • Skinship Grope: Inflicts this on Miia at the end of her debut chapter while the two are reconciling.
  • Too Kinky to Torture: After eating some of Miia's cooking, it brings to mind having her fins painfully split apart into legs. Afterwards, she is seen collapsed on the floor smiling about it, despite foaming at the mouth. Later, once Rachnera ties her up, she finds herself rather enjoying it.
  • Tragedy: She just loves to be a victim of tragedy in general, whether it's unrequited love, her lover dying, or herself dying and leaving her lover behind. Miia even calls her a "tragedy freak."
    • Netorare: A fan of being on the losing end, as per her The Little Mermaid fetish. Chapter 19 deconstructs this to let her know that it isn't what she thought it was going to be.
    • Someone to Remember Him By: After realizing that it wasn't all it was cracked up to be, and believing that Kimihito was soon going to die, she immediately tried to seduce him in order to have this sort of tragedy instead.
    • Unrequited Tragic Maiden: She wants to be one. She doesn't want to be a third lover though; there's no tragic romance when it comes to third place.
  • Visual Pun: Mermaid. Get it?
  • Wardrobe Malfunction: Mermaids secrete a slime to keep themselves moist. The result causes this to happen.
  • Waterfall Puke: Afflicted with this when she starts getting chlorine poisoning from the pool.

Rachnera Arachnera

An Arachne and the fifth girl to officially move in with Kimihito. Her original host family had sold her off to the director because they were expecting a monster girl who wasn't so...monstrous. This and the director's behavior left her hating humans, until she met Kimihito.

  • Action Girl: Miia jumps at her when she first shows up and tries to put the moves on Kimihito. She's completely restrained in webbing a panel later with Rachnee ignoring her outright.
  • Affectionate Nickname: The household starts calling her "Rachnee" as soon as she moves in.
  • Armor-Piercing Question: From Chapter 18, to Miia.
    Rachnera: You're making a huge fuss about [Kimihito] cheating on you, but do you really think you can stand to witness it? Can you really handle seeing your beloved Darling making love to another woman?
    • For the record, he isn't, but Miia looks scared there.
  • Bare Your Midriff: Well, when your body makes pants impossible...
  • Beneath the Mask: Due to her Freudian Excuse from her host family, she detests hypocrites and people putting on a mask of false kindness. She would rather see the person be their honest self than the mask they wear.
  • Berserk Button: Do not poke fun at her Freudian Excuse or she will tie you up bondage style.
  • Bizarre Alien Biology:
    • Apparently breathes out of her abdomen, like regular spiders. Miia thinks she can also breath out her mouth, but it's not clear if that's actually true.
    • Like spiders, Rachnee gets drunk on caffeine.
  • Broken Bird: From what can be seen of her in a flashback, she was not always bitter towards humans.
  • Brutal Honesty: Rachnera generally does this as she doesn't like sugar-coating things. Such as when she tells Centorea her sandwiches are not very good because she just put chopped raw vegetables between two pieces of bread.
  • Casual Kink: Really enjoys tying people up much like a dominatrix would. And she enjoys testing new methods on the other girls.
  • Cuddle Bug: Separate from her love of tying others up she tends to get very tactile with Kimihito when she's in a good mood, to a point that rivals even Miia. She especially seems to like caressing him, which is quite impressive given how sharp her claws are and how she manages to do it without injuring him. She makes ample use of her breasts as well. Kimihito can't seem to bring himself to object to this all that much.
  • Extra Eyes: She has six eyes.
  • Fangs Are Evil: At first they come off this way, but eventually Rachnera's mood improves and they become Cute Little Fangs.
  • Femme Fatalons: Sort of. Her arms are covered in a black carapace from the shoulders down, and the gauntlet-like plating on her digits end in sharpened points.
  • Freakiness Shame: Not so much shame as realizing people may be put off by her spider parts. Kimihito admitting that he finds her legs charming is part of what gets her to realize he's not a bad person at all.
  • Freudian Excuse: After her rejection from her first host family and being sold off into slavery, she's very bitter towards the human race and slow to trust anyone.
    • In chapter 26 it is explained that she accidentally harmed the daughter of the host family, Ren Kunazuki. The incident made the parents thought it was impossible to live with her and sold her.
  • The Gadfly: She'll often say things just to rile up the other girls, especially Miia.
  • Hidden Depths: Lilith, after being captured, sneers that the reason Rachnera is a Stealth Expert and The Tease is that she's so afraid of suffering prejudice and rejection again that she tries to stay out of the public eye and keep friendships going under her own terms. While she doesn't directly respond, Rachnera's furious response implies that Lilith touched a nerve.
  • Humans Are the Real Monsters: Her general opinion on them. She tries to prove that Kimihito is no different, and eventually opts to arrange to move in with him when she finds out that he is, in fact, a decent person who doesn't discriminate against non-humans.
  • Hypocritical Humor: Calls Kimihito a hypocrite for getting turned on by her human parts, believing that like other humans, he finds her spider half disgusting. When he states he finds her legs to be "charming," she laughs at him and calls him a pervert who gets turned on by spider legs (and given that none of the monster girls he lives with have normal human legs if they have legs at all.....).
  • Kill the Ones You Love: She sides with Lala while believing she's actually a grim reaper, with the reasoning being if Kimihito has to die they should just let it happen rather than subject him to all of the injuries he suffers from the other girls trying to outrun her. Fortunately he's not really going to die.
  • Logical Weakness: As stated in the chapter 23 extra, "Arachne are helpless against those they cannot ensnare or tie up.". Promptly demonstrated by Suu. Again.
  • Marshmallow Hell: After noticing Kimihito's hard-on she sets up her web in a way that if he opens his mouth he'll fall, strips off her top, and proceeds to inflict this on him as "punishment".
  • Monochromatic Eyes: Her eyes are pure red, lending to her creepy appearance.
  • Nightmare Face: Holy BALLS can she pull one off!
  • Obviously Evil: Subverted. She has a massive skull design on her spider-like body and dresses like a Femme Fatale, and her first appearance involves more or less mummifying a man and expressing an implied violent interest in Kimihito. She kidnaps him, binds him in webbing, and suspends him from the ceiling repeatedly. She's actually just a rightfully bitter person who's been screwed over by humans repeatedly, looking for one that's actually decent and worth living with.
    • Played up by Rachnera when called for. She is aware of how dangerous she looks and has no qualms about using this to her advantage.
  • Offscreen Teleportation: Seems to move very, very fast when not in a frame. For instance suddenly appearing on the ceiling when she was on the floor a moment ago. Justified by the fact that fleeing spiders are pretty quick.
  • Pay Evil unto Evil: When she finds out that there might be a decent human, Kimihito, she turns on the director, encasing him in webbing and leaving him for the police to find, and proceeds to use that time to abduct and investigate Kimihito.
  • Peek-a-Bangs: Sometimes, but not always. It usually happens when she's being especially standoffish or cynical.
  • Scary Teeth: She has shark-like teeth, though they're only really noticeable when she's pissed off.
  • She's Got Legs: Eight of 'em, according to Kimihito.
  • Spider People: She's an Arachne.
  • Spiders Are Scary: Zig-zagged, as seen above. While she's actually not too bad most of the time, she can be downright terrifying when the situation calls for it.
  • Spider-Sense: Acute enough to dodge a sniper round.
  • Stealth Expert: Despite her size, Rachnera is quite good at remaining unseen thanks to her Wall Crawling skills and Spider-Sense.
  • Stripperiffic: Easily the most provocatively-dressed of the girls, barring Suu.
  • Super Human Trafficking: Her original host family sold her off to the director, who used her and her webbing to make money.
  • The Tease: Kind of a lot, actually, even by this manga's standards. She pretty much starts putting the moves on Kimihito - albeit in a mocking fashion - even before she moves in. Once she does move in, she spends an entire day trying to get into his pants.
  • Token Evil Teammate: She's not evil per se, but she does enjoy tying up the other girls, except Suu, who she's unable to bind at all. And when she first ties up Lala, she's unable to get a response due to the latter missing her head at the time.
  • Underboobs: So much so that the first time Kimihito was on the ground looking up at her, her nipples were totally exposed. Even her more casual articles of clothing leave a generous amount exposed.
  • You Gotta Have Light Lavender Hair: Lends well to her "dark" appearance.


A Dullahan, the second "D", and the sixth girl to officially move in with Kimihito. She initially introduced herself as a grim reaper who was there due to Kimihito's impending death, when in fact she merely enjoys pretending to be a grim reaper and really showed up because she was on the run from Ms. Smith and fascinated by Kimihito's apparent invulnerability.

  • Badass in Distress: Her head and body being so far separated keeps her from using her powers. This would normally not be much of a problem according to her, but she doesn't have the time as she's being hunted by "The Organization".
    • It's revealed in Chapter 24 that the so called "Organization" is just Ms. Smith doing her job of making sure that she isn't running off on her host families.
  • Bait and Switch: Initially implied to be the second "D", she actually arrived to warn Kimihito about his impending death. When questioned about the note, her response is that her only purpose in interacting with mortals is to warn them of their deaths, so it was assumed she did not write the letter. It's then revealed she really is the second "D".
  • Black Eyes of Crazy: She has black sclera and is sinister and morbid, but like Doppel and Lilith she's not evil.
  • Glowing Eyes of Doom: While her head is on her shoulders, they appear normal. Once she's carrying her head in her hands behind Kimihito they appear to be glowing. After being revealed completely, the glow is gone.
  • Gory Discretion Shot: Her neck stump looks just as you'd expect from a normal decapitated body, to Miia's horror.
  • Goth: Turns out that this is basically what she is. Her speeches about being death and unstoppable and such is the same sort of thing you hear from some angry kid discovering black makeup for the first time—her ability to pull her own head off just gives her a bit more dramatic strength.
  • The Grim Reaper: She's a Dullahan and refers to herself as both "Death Incarnate" and "The Huntress of Death": ultimately, it's averted, however. In the end, she's just a Monster Girl no more supernatural than the rest of the girls, and her connection to Death is her just playing pretend.
  • Headless Horsewoman: She's a Dullahan, this comes with the territory. No word on if she has a horse or bike though.
  • Idiot Hair: In the shape of a scythe. It's nearly as large as Nyarko's.
  • The Immodest Orgasm: Courtesy of Rachnera and Suu on her body while Kimihito and a few of the girls are looking for her head.
  • Losing Your Head: She lost her head approaching Kimihito and had to get his assistance in finding it as it went rolling downhill and into a park.
  • Ms. Imagination: Turns out that all her death talk and being a grim reaper is just delusional banter equivalent to 8th grader syndrome.
  • Offscreen Teleportation: She manages to cross a street and get behind Kimihito in the time it took for a truck to pass by breaking his line of sight on her. She pulls it off again when chasing him and the other girls down. She had Rachnera's assistance that time.
    • Justified since in the Irish tales, once a Dullahan is after you, you will not get away unless you throw gold at them.
  • Red Oni, Blue Oni: An interesting case where the head is blue and the body is red. Her head acts calm with little emotion but the body, ironically, is more expressive when they are separate.
  • Scarf of Asskicking: Used to hold her head in place.
  • Shy Finger Twiddling: She does this sometimes, usually when confronted by Ms. Smith.
  • Sinister Scythe: And she uses it to apparently prepare to decapitate Kimihito, hooking him around the neck as the chapter just ends. Turns out she did this to get his attention. It apparently has an indent in it.
  • Shown Their Work: The girls mention a "horse-drawn carriage with a headless rider" and the image showed the horse also missing its head. In certain tellings of Dullahan stories, this is another way they can appear.
  • Zettai Ryouiki: Grade-A with her boots as best seen here.


A squad of four female monsters and Ms. Smith, who go after those monsters who exploit the Interspecies Protection Act.

In General
  • Amazon Brigade: One wonders why, actually. You know, besides the obvious answer.
  • Five-Man Band
    • The Leader: Ms. Smith tends to be the one orchestrating how things should play out, though being human leaves her typically unable to directly assist.
    • The Lancer: Zombina, being declared the group's commander, is in charge of more immediate matters for MON while actively working.
    • The Smart Guy: Doppel; being required to know how she needs to look and act to deceive enemies puts her in this role.
    • The Big Guy: Shared between Manako and Tionishia. Manako has shown the ability to quickly disable a large number of enemies, while Tionishia is noted to be the strongest of the group and utilizes that strength to bypass things like walls.
    • The Chick: Shared between Manako and Tionishia. Manako feels that she's not really considered part of the group for being required to stay at a distance and her specialty requires the element of surprise so she can't repeatedly assist the group on the same mission. Tionishia, despite her strength, is more used simply to guard and escort hostages and can be seen trying to keep the group from fighting amongst themselves and attempting to boost morale, especially Manako's.
  • Fun with Acronyms: "MON" apparently stands for "Monsters of a Neuro".
    • The official English version has it stand for "Monster Ops: Neutralization".
  • Pretty Freeloaders: In Volume 3's extra, Kimihito and Meron point out that they spend a lot of time at his house. And in Meron's pool specifically.
  • Ragtag Bunch of Misfits: They have varying degrees of professionalism and wildly different personalities, but they're pretty competent at their jobs.
  • Single Woman Seeks Good Man: Strongly hinted at at the end of Chapter 22. Zombina, Tionishia, and Manako all admit to having enjoyed their time with Kimihito, and immediately switch the conversation to looking into doing the homestay thing as well when their boss is notorious for just dumping more and more girls into Kimihito's home.


A living dead and commander of the squad.

  • Alien Blood: Her blood is a special anti-decomposition fluid made from a formaldehyde base and is circulated by an artificial heart. The fluid is hazardous to the living.
  • Blood Knight: She's shown to be enjoying herself during the hostage situation in chapter 11, and at the end of chapter 15's hostage situation her only concern was that she didn't even get to shoot someone.
  • Butt Monkey: In chapter 20, she spends most of the time getting stomped on by giant monsters, culminating with her buried in a crater. It's okay though, since she's already dead.
  • Dead to Begin With: Obviously.
  • Deliberate Injury Gambit: She used being gunned down and left for dead to her advantage to later surprise the orcs with the fact that she was not really dead (well, permanently) and also very much armed.
  • Fangirl: Enjoys zombie films, and after seeing one on her "date," begins enthusiastically discussing the various tropes and trends of the genre.
  • Feel No Pain: She explicitly states it while hanging out with Kimihito. Whether she can feel... other things is more ambiguous. Now, considering the fact that she moaned when Kimihito inadvertently pinched her nipple and her embarrassment that she did so the evidence suggesting that she can feel pleasure is rather solid.
  • Good Thing You Were Dead To Begin With: Zombina getting horribly injured has pretty much become a Running Gag.
  • Gun Kata: She's been seen to strike rather elaborate poses while shooting, arguably not for the reduced target area this would usually be for and simply because it's cool as her primary concern over getting shot is what it'll do for her weight.
  • Guns Akimbo: Fond of wielding a gun in each hand, whether they be submachine guns or assault rifles.
    • A-Team Firing: Actually hitting stuff with them, on the other hand...
  • Gun Twirling: Does this to adjust her guns to have them aiming back at herself to shoot the orc holding her.
  • Hammerspace: When she first shows up, there are no weapons visible on her. When she gets back up, she suddenly has a pair of guns.
  • Hot-Blooded: Zombina has no problems with shooting herself to shoot others and insists that it would be badass if Manako sawed off the end of her gun and got a second one to go with it.
  • Hypocritical Humor: Somewhat dislikes movies with fast, active zombies... despite being one herself.
  • Immune to Bullets: Her only concern over being shot is what it'll do for her weight.
  • The Lad-ette: Loves action, violent movies, munching meat, and hot-blooded shouting.
  • Luminescent Blush: After being told by Kimihito that he doesn't think of her as a corpse but an actual person she begins to blush, and continues to do so while he sews her boob back on. The impossibility of this is Lampshaded by her thinking that her heart might start beating again.
  • Mismatched Eyes: One eye with a dark iris and the other with a light iris. Her left eye was replaced with a transplant after losing the original.
  • Mix-and-Match Man: While she refers to herself specifically as a zombie, her appearance gives off the impression of being put together from parts from multiple corpses. Her heart and blood are artificial, and her left eye is a transplant.
  • Nigh-Invulnerability: Par for the course, considering she's an undead. She can shake off bullets with ease as stated above, and getting crushed by two kaiju didn't seem to have done any lasting damage.
  • Ninja Pirate Zombie Robot: Ninja Zombie SWAT-Policewoman anyway.
  • Oh Crap: She manages a deadpan "Uh..." as a giant-sized Suu and Kii topple directly at her.
  • Shoot the Hostage: Zombina, being undead, is not adverse to shooting through her own body to surprise kidnappers.
  • Slasher Smile: A little TOO into hurting people.
  • The Tease: During her "date," when she undoes the stitches on one of her boobs to see how Kimihito will react.
  • Tempting Fate: In Chapter 20, she joked about how being around a toxic waste dump would make someone grow until they were a giant. This is exactly what happens to Kii and Suu.
    • In an extra at the end of Volume 3, she calls Doppel out on her attempts to tan, after having her own called out, since there's no way Doppel would get any darker. The next panel has Doppel changing herself to be pitch black.
  • Yaoi Fangirl: According to her profile she bounces around between fandoms, recently switching from Kuroko No Basuke to Attack on Titan, and ships everything from Levi x Eren to Bertholt x Eren.


A doppelgänger who serves as the infiltrator of the squad, due to her shapeshifting abilities.

  • Black Eyes of Crazy: Not really crazy, but she does have black sclerae in her default form.
  • Body Double: Serves as one for Ms. Smith
  • Dark-Skinned Blond: In her Shapeshifter Default Form.
  • Doppelgänger: She presents herself as one for the convenience of others, as whatever she actually is is beyond comprehension and a Doppelganger is simply the closest thing we can imagine.
  • The Gadfly: Enjoys playing around with people's feelings for fun and profit. Case in point, she was behind the first "D" letter.
  • Hair Tropes: She covers quite a few.
    • Godiva Hair: Always manages to conveniently cover her more sensitive parts. It's stated that no matter what angle you try to look from her hair will always appear to be covering it.
    • Prehensile Hair: Capable of wrapping herself with it to form her disguises.
    • Rapunzel Hair: Her hair is about as long as she is.
  • Humanoid Abomination: Her true appearance, real name, and even native language, are all beyond human comprehension. Her "faceless" self is described as having hair-like tentacles and jet black skin, an appearance she uses to freak people out.
  • Incredibly Obvious Tail: Despite using a disguise that screams this all throughout Chapter 22, she avoids detection from everyone except Manako by simply doing things that fit in with the background events. She finally blows her cover by fitting into this trope both in appearance and action.
  • Kick Chick: She escapes from the orc holding her by kicking straight up until her foot reaches his face behind her.
  • Naked People Are Funny: Doppel is actually always naked; the clothes of her disguises come from her hair.
  • Oddly Visible Eyebrows: Perhaps one of the few examples with an explanation. As stated above, her hair will always appear conveniently placed. Apparently this includes being "behind" her eyes so as to not obscure them.
  • The Prankster: Wrote the original threatening note to try to push Kimihito out of maintaining a Balanced Harem.
    • Nice Job Breaking It, Hero: Not only did it backfire spectacularly by allowing Kimihito to get even closer to all the girls, but it also seemed to have sparked an interest in him among her coworkers, and worst of all it ensured that when a real threatening letter came in MON didn't realize it was from a different source until it was too late.
  • Voluntary Shapeshifting: Though clothes seem to be optional. She mostly uses it to sneak into sensitive places.


A cyclops who serves as the sniper of the squad, due to her keen vision.

  • A-Cup Angst: She is especially conscious of her flat chest.
  • All of the Other Reindeer: She assumes this is why she was told to snipe from 2km away.
  • BFG: Her huge sniper rifle.
  • Briefcase Blaster: Of the shaped like a briefcase variety. She carries it around with her on her date with Kimihito.
  • Cry Cute: Prone to these. This is mentioned as something of a racial trait to keep their eyes from drying out, but even among other Cyclops she's considered a crybaby.
  • Cyclops: Though not really a giant. She's actually pretty short.
  • Freakiness Shame: She believes the world hates her for having just one eye, and notes that most people feel a little uncomfortable meeting her gaze.
    Manako: A little kid ran away from me again... This world truly does hate cyclops...
  • Friendly Sniper: And really insecure about herself to boot.
  • Hyper Awareness: She's incredibly observant about the people and things around her, such as noticing slight changes in a person's gaze or being able to snipe despite having no depth perception. She also spots "D" stalking the MON dates, likely even before the reader; Checking a clothes rack while Kimihito speaks with Zombina on Tionishia's date, checking some books to the left of the drink bar on Zombina's date, and finally twice during her own date buying a hot dog and hiding behind a vending machine while watching them.
  • Improbable Aiming Skills: 2km away and she snipes every gun the orcs are carrying without missing, hitting them, or their hostage. Without a scope.
    • Applying a silencer to her gun, however, is noted by her to somehow make it extremely difficult to aim.
  • Logical Weakness: She has poor depth perception and is likely to bump into things.
  • Muscles Are Meaningless: She's actually pretty lanky.
  • Punny Name: Manako sounds very similar to the word "monocle", an eye-wear meant for a single eye. It is also a Japanese word for "eye."
  • Running Gag: Several chapters that she's shown up in, she's made comments about her eye hurting or being dry while tearing up. Her insecurity over how people might treat her over her eye comes up often as well.
  • Shrinking Violet: The shyest and most insecure girl of the series, not just MON.
  • Super Speed: She manages to cover the 2km distance on foot in just a matter of minutes and implies it would've been less but her enormous gun slowed her down.
  • Youkai: It should also be noted that Manako shares more in common with the youkai Hitotsume-Kozo than anything from Classical Mythology. (Including having childish proportions in contrast to being a giant)


An ogre who serves as hostage escort/guard of the squad, due to her immense size and power.

  • Big Eater: Literally. Her massive size probably has something to do with her appetite. She's been known to eat entire cakes, as well as ice cream by the liter.
  • Boobs of Steel: The physically strongest member of MON as well as the bustiest.
  • Dark-Skinned Blond: Usually how she's drawn, though we haven't gotten a color picture yet.
  • The Fashionista: The majority of the money she makes is stated to go into buying clothing and accessories, in part due to needing everything custom made. Manako's profile states that the entire group has high standards for fashion, but notes Tionishia as having the highest standards.
  • Gag Boobs: So massive they make Centoria's look normal by comparison. Her profile lists her as being a P Cup, and that that's large even among Ogres. Her bras are custom made and reinforced, described as a "marvel of modern engineering".
  • Genki Girl: Drags Kimihito from shop to shop all over town on their "date."
  • Gentle Giant: Despite her impressive size and strength, she is primarily the group's guard and escort, and typically uses her strength merely for forcible entry. She also tries to insist that the group not fight amongst themselves and shows support for even the slightest of accomplishments.
  • Girly Bruiser: She's larger than life with strength to match, but she's still The Heart of the team, has rather feminine mannerisms, and a penchant for cute things judging by how she tried to take a dolphin from the aquarium. And if her "date" is any indication, she loves shopping for really girly stuff.
  • Horned Humanoid: Like most oni.
  • Huge Schoolgirl: Though Tionisha is no longer a schoolgirl, she remains very sensitive about her great size.
  • I'm Taking Her Home with Me!: With a dolphin.
  • Inappropriate Hunger: They're in the middle of dealing with a hostage situation and she feels the need to, and actually does, start eating some chips.
    • In chapter 15, after yet another hostage situation has been resolved, she is seen eating from a bag of chips.
  • Incredibly Obvious Tail: While trying to spy on one of the "bait dates."
  • Marshmallow Hell: Gives Kimihito this treatment in Chapter 22.
  • Muscles Are Meaningless: She has a rather slender figure underneath the armor. Doesn't stop her from throwing a vending machine with her bare hands.
  • Shopping Montage: On her "date."
  • Statuesque Stunner: She's noted to be at least 7 feet tall, and in comparison to Kimihito is a couple heads taller. Even among most monster girls she's apparently large, as the clothes at a store specifically stocked for extreme sizes were still too small for her.
  • There Was a Door: Justified. Going into a hostage situation straight through a door would not be the wisest of ideas.
  • Youkai: The only monster so far with an Asian origin, though there is a rough Western equivalent. The English version simply refers to her as an Ogre.



A kobold who runs a fitness center for extraspecies, and the first non-government monster girl to NOT be added to the harem.

  • Cute Little Fangs: Comes with being a kobold.
  • Genki Girl: Polt seems to have near-infinite reserves of energy.
  • Large Ham: She's likes to shout. A lot.
  • Little Bit Beastly: Dog ears, nose and tail, along with claws, fangs and tufts of fur near her wrists.
  • Male Gaze: One panel in Chapter 17 seems veeeery focused on her tail, and the hole her swimsuit has for it. And Mero's inability to stretch.
  • Perpetual Smiler: The only time she isn't smiling is when she's surprised.
  • Reasonable Authority Figure: She is genuinely concerned with how the fitness center will be received and when issues are brought up, such as Mero not handling the chlorinated water in the pool well or the temperature being too cold for Miia, she says she will make sure when the place opens to the public, they will be fixed.


A unknown individual who has sent Kimihito a death threat. Revealed to be two people Doppel and Lala. For further details see their entries.

  • Bait and Switch: So far it's been assumed that Draco, Kii, Lilith, and Lala were "D". After her initial reveal presents her as being innocent, she immediately slips into the same behaviors as in her note in the following chapter, revealing that Lala was the second "D" after all.
  • The Ghost: Up until The Reveal, they had not been seen. All that's known about them is the note.
  • Purple Prose: Though not all of it can be seen the second note is quiet poetic, especially compared to the original blunt threat of the first. This hints at the fact that it's not the same "D" as the initial writer who was revealed to be Doppel pranking them.
    I will bring death upon you. Death will bind us. ~ Together with you, I want to be together ~ Instead of allowing you a short life ~ me. We will spend life in eternal dark ~ now, time will fly like the wind and ~ lusion. The eternity of death wil ~ e.
  • Together in Death: Their ultimate goal, if the second letter is to be believed.
  • Yandere: Everything they've done so far screams it. It turns out that she's not. She just enjoys pretending to be a grim reaper.


A dragonewt with a creepy crush on Miia.


A dryad whom Papi befriended before she met Kimihito. However, illegally dumped chemicals have transformed her into a rampaging monster, who Papi (and by extension, Kimihito) have to stop.

  • Attack of the 50-Foot Whatever: Turns into a giant, mobile tree and attacks the first people she encounters.
  • Bondage Is Bad: Ties Papi up tortoise-shell style with vines and tightens them until she orgasms.
  • Combat Tentacles: Uses vines to grab onto people… and wrap them up BSDM style.
  • Cool Chair: She has a throne made of roots that can move by itself.
  • Forgotten Friend, New Foe: Comes across as such at first due to having been driven crazy by the chemicals she was exposed to, and Papi having completely forgotten about her.
  • Freudian Excuse: Her hatred of humans stems from her kidnapping by extraspecies traffickers and being left behind by Ms. Smith when the traffickers were apprehended.
  • Godiva Hair: Her vine-like hair covers her nipples in some scenes, but not all of them.
  • Humans Are the Real Monsters: Dislikes humans in general… though she admits that Kimihito has good technique.
  • Idiot Hair: A big, leafy one.
  • Immodest Orgasm: When Papi and Kimihito suck the fertilizer out through her breasts, she has one.
  • One-Winged Angel: After absorbing experimental fertilizer for several months, she transforms into a massive plant monster.
  • Overnight Age-Up: Exposure to the experimental fertiliser caused her to grow from looking like a small girl to a buxom young woman. She reveted once the chemicals were out of her system.
  • Plant Person: She's a dryad, who looks mostly human with plant features such as leaves and vines for hair and bark covering her arms and legs.
  • Plot-Relevant Age-Up: Normally looks like a child, but after absorbing experimental fertilizer, she gains a body of a busty adult (which happens to be inside a giant tree monster body). She gains this form naturally when she's met again in Chapter 25.
  • Psycho Serum: Absorbed experimental fertilizer, which had a number of effects on her.
  • Punny Name: Ki is the Japanese word for tree/wood. Granted, it's probably not her real name, since Papi made it up for her.
  • Sexier Alter Ego: Like Suu, Ki can assume a more... adult-looking form at will.
  • Shout-Out: Her One-Winged Angel appears to be one to the forest god from Hellboy II: The Golden Army.
  • Super Human Trafficking: Was the victim of this, which is the reason she dislikes humans.
  • Stripperiffic: Doesn't wear any clothes, aside from some bark-like covering on her neck and chest... which leaves her breasts exposed.
  • Yandere: Comes across as such for Papi, though it's not her fault.


A mischievous devil who decides to cause some trouble to Kimihito and Centorea's date for her own amusement.

  • Ambiguously Gay: Possibly as she greatly enjoys being tied up and "tortured" by Rachnera to the point where she was begging to be "rewarded".
  • Black Eyes of Crazy: Like Doppel she has black sclera, but she seems more mischievous than malicious or insane.
  • Casual Kink: Really enjoys bondage and refers to Rachnera as "Mistress".
  • Forgot About His Powers: When confronted by a wild boar she runs away from it instead of flying away. Then again, it's unknown if she's even capable of flying.
  • Horned Humanoid: Comes with being a demon.
  • Hypnotic Eyes: Causes Centorea to develop these.
  • In the Hood: Wears a hoodie to hide her horns. The bagginess of the hoodie also helps to hide her tail and wings, with a pair of zippers in the back to let the wings out if she needs them.
  • It Amused Me: Her modus operandi.
  • Kick the Dog: She could have hypnotized Manako to be rid of her, instead she simply exploits her insecurity about her eye by pretending to be a child traumatized by the eye.
  • Mind Manipulation: She can hypnotize people, and tries to get Centorea to rape Kimihito as a prank.
  • Older than They Look: Like Papi she is an adult but has the body of a small child.
  • Our Demons Are Different: She's a devil, but the only supernatural powers she seems to possess are hypnotism.
  • Outside-Context Villain: Unlike the other one-off villains so far, Lilith has no real motive beyond causing mischief for her own amusement and doesn't seem to have a host family she's staying with.
  • The Prankster: Continuously pranks Centorea and Kimihito throughout Chapter 21, undergoing Serial Escalation until she brainwashes Centorea into trying to rape Kimihito. It bites her in the ass when she presses Rachnera's Berserk Button.
  • Sexy Coat Flashing: She's wearing a coat, underwear, and not much else.
  • Too Kinky to Torture: Judging by the last page in chapter 21 she really enjoys bondage.
  • The Unfought: Played with. Centorea misunderstands the nature of her "hypnosis," and Kimihito never even learns she existed, but Rachnera catches her and settles her good.
  • Winged Humanoid: Has small bat-like wings.
  • Zettai Ryouiki: Class B thanks to her jacket.
