    Kimihito Kurusu

Voiced by: Junji Majima

The protagonist, host of Miia, Papi, Centorea, Suu, Meroune, Rachnera, and Lala, and guinea pig for the inter-species marriage amendment to the exchange program.
  • Above the Influence: Despite the various advances by the girls, he never takes advantage of them sexually. Of course it also slightly helps that they're usually displaying Clingy Jealous Girl behaviors to prevent any one of them from getting too far ahead of them regarding a relationship with him. Even when Lilith, a lesser devil, outright hypnotizes him into giving in to his desires, he still smacks her upside the head and says how wrong that is.
  • Accidental Pervert: All the time. Though he gets beat up for it less than you'd think: most of the girls are either regularly trying to seduce him or not at all adverse to the idea, and thus want him to act like a pervert.
  • Affectionate Nickname: Even though the readers know his real name, the girls often make him Only Known By His Nickname, as demonstrated by the following:
    • Miia calls Kimihito "Darling"
    • Papi calls him "Husband" ("Boss" in the English manga, "Master" in the anime − in Japanese "Goshujin" can mean either husband or master)
    • Centorea calls him "Master" ("Milord" in the English manga); Suu does as well, but in English
    • Meroune calls him "Sir" ("Beloved" in the English manga, "Master" in the anime)
    • Rachnera calls him "Honey"
    • Tionishia calls him "Sweetie" ("Snookums" in the English manga)
    • Zombina calls him "Babe" ("Loverboy" in the English manga)
    • Manako calls him "Dear"
    • Doppel calls him "Bae"note 
    • Ms. Smith calls him "Darling-kun" to pick on him.
  • Alliterative Name: Kimihito Kurusu.
  • 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.
  • Bad Bad Acting: Chapter 40 shows that Kimihito is not very good at acting.
  • Badass Normal: While he's your average human (for certain values of "average"), 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.
  • Berserk Button: As revealed in the volume 6 omake, the girls had never seen Darling so angry until Lala played with her food instead of eating it. Miia and Papi witness a major scolding so terrifying that they'll wash their dishes without complaints.
  • 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.
  • A Bloody Mess: In their excitement, Miia, Papi, and Centorea tackled Kimihito when he was rummaging through the fridge. Cue him lying on the ground with red liquid pooling around him. Turns out it was only ketchup, but the girls were horrified.
  • Breaking the Fourth Wall: Does this in chapter 8 after Centorea says she'll protect him from the slime.
    Kimihito: 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.
  • Butt Monkey: He always gets caught in his harem's antics or gets hurt as a result of their aggressive affections.
  • Cathartic Scream: Shoves his head inside Suu's body and screams at the top of his lungs when he learns that The Organization will cover all living expenses, basically meaning he put himself through hell all throughout chapter 25 for nothing.
  • Celibate Hero: At first, 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. By chapter 30 he outright admits to himself he would like to be married to any one of the girls, which makes the idea of choosing all the harder.
  • Chick Magnet: Initially you could count the girls who weren't interested in him on one hand, though this number has increased substantially as the manga progressed.
  • Crazy-Prepared: When Suu is on her water-absorbing (and orgasm-inducing) rampage in chapter 10 she leaps at Mero. Kimihito immediately produces a large plastic garbage bag to catch her mid-flight and contain her.
    Kimihito: 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.
  • Determinator: While he could be said to have this in general, it's taken to an extreme in chapter 30. Determined to accept all the girls' feelings, he decides to not tell them to stop when they go too far. This results in multiple near-death experiences, which he apparently only survives because he is so determined to accept the girls that he refuses to die. According to Lala, he was doing the same thing during his close calls in previous chapters, and it was one of the things that caught her attention about him. It seems to literally be a super-power that Lala doesn't really explain. However, his body can't keep up with his determination, so he is now working on strengthening it.
  • 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 Meroune. Mero'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".
  • Friend to All Children: During chapter 38, he played regularly with the hospitalized children while the doctors tried to figure out just what kind of condition allows him to survive everything he goes through. Partly because he was bored being confined to bed-rest, partly because, hey, they're sweet kids.
  • Got Volunteered: Ms. Smith pretty much just dumps "problem cases" at his house. Of the girls he deals with, only Miia and Meroune 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. To make it worse, she first dropped Miia with him by mistake, and he was too much of a Nice Guy to kick her out. Everything sort of snowballed from there.
  • Honor Before Reason: Defending Zombina from harm, despite the fact she doesn't need the protection, because the fact she's a girl in danger matters more than her being a zombie.
  • House Husband: He enjoys cooking, cleaning, and sewing. His skills are useful when the monster girls get clothes that need adjusting.
  • 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 make remarks on Miia's fantasies about him.
  • Incorruptible Pure Pureness: When Lilith attempts to hypnotize him into releasing his inhibitions, he ends up getting hypnotized into demanding she stop it with the seduction already.
  • Invulnerable Knuckles: Considering how durable the guy is, it's notable that he doesn't seem to have these: after clocking the racist guy the anime version shows that his fist is clearly raw, and in the very next scene Smith is treating him; he didn't brace his wrist properly and ended up hurting himself more than the guy he punched.
  • Iron Butt Monkey: In true form. Lala's debut is a giant lampshade of this. Chapter 30 reveals he's not so much invulnerable as he is so determined that he somehow refuses to die, which somehow brings him back largely unhurt.
  • 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.
    • Hilariously lampshaded in Chapter 38. All that abuse and potentially lethal injuries did not even leave a dent on him, utterly confusing the doctors.
  • 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. Incidentally, 主公人 looks like 主人公 (shujinkou, "main character"), and his family name basically means "where people come and stay".
  • 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 (and rather easily, at that) she begins to panic in embarrassment.
  • Near-Death Experience: He has had several through the series. He even sees part of the afterlife in Chapter 30 where Lala is waiting and watching. It turns out his experiencing these for completely noble and selfless reasons is what drew her to meet him in person.
  • 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. Unfortunately, this is Deconstructed as well: the trait is also his biggest weakness in that it can make him incredibly indecisive, as he tries to please everyone. While he usually finds a way to make it work, the issue of finding a girl to marry is a whole 'nother ball game...
  • Oblivious to Love: Averted: he's well aware of the girls' feelings and tries his hardest not to hurt anyone's feelings or show blatant favoritism to any of the girls at any time. He also freely admits to himself that he'd enjoy being married to any of them.
  • 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 Known by Their Nickname: His actual name is mentioned only once or twice, otherwise it's always one of his nicknames. This trope has gone meta, with many readers only remembering his nickname.
  • 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.
  • Please Put Some Clothes On: He gets really uncomfortable around naked women. When Lilith tried to seduce him by stripping, he repeatedly told her to put some clothes on. When Doppel offers to do anything he wants, his only request is for her to wear actual clothes. Which embarrasses the hell out of her.
  • Screw Destiny: Immediately after his Tempting Fate, 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!
  • 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 Chapter 25. Happens again in Chapter 35, where he manages to make some impressive dishes out of stingrays of all things.
  • Taking the Bullet:
    • 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.
    • Takes a hit from Cici while defending Zombina in chapter 39.
  • Teeny Weenie: The subject of several jokes in Chapter 31, though whether or not it's due to the cold weather is up for grabs.
  • 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!
  • They Killed Kenny Again: According to Lala in Chapter 30, he repeatedly died, but came back to life every time.
  • Tiny Guy, Huge Girl: When next to Centorea, Rachnera and Tionishia in any case. He's shown to be fairly average height, though a bit on the shorter side.
  • 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.
    • Exceptions seem to include when his household responsibilities are threatened (i.e. the prospect of not getting enough food for everyone really upsets him), as well as the girls acting out of character (he outright panics when Papi begins explaining in detail harpy society and the situation with her mother).
  • Unluckily Lucky: On one hand, he regularly survives grievous injuries with no lasting effects. On the other hand, a person that was really lucky wouldn't get those injuries in the first place.
  • 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. She does it yet again to him in chapter 30, though under purely playful conditions.
  • Workaholic: He's so used to doing housework all the time that he's actually uncomfortable when he doesn't have anything to do. When the kitchen staff in Chapter 35 were in jeopardy, he immediately helps them out, cleans several stacks of dishes, and even asks if there's more he can do. This prompts Rachnera to call him a workaholic.
  • 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... Or not.

    Kuroko Smith

Voiced by: Yuu Kobayashi

Kimihito's cultural exchange coordinator, and the leader of MON. 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.
  • All There in the Manual: Her first name has not been said in the manga or anime, but was revealed with official merchandise
  • Ambiguously Bi: She clearly has a bit of a thing for Kimihito, but she also spent most of the jousting match in chapter 29 enjoying the sight of Centorea and her mom's boobs bouncing.
  • 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.
  • Bunny-Ears Lawyer: Despite the fact that she can be lazy and forgetful, and routinely bums for food (or coffee) or messes with Kimihito for the fun of it, Smith is very good and proactive at her job as the coordinator. She also runs MON, which is effectively a second full-time job.
  • Cheshire Cat Grin: A mischievous, teasing smirk (which she wears constantly) is her trademark expression.
  • 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.
  • 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.
  • First Name Basis: With most of the cast, even though she does interact with them non-professionally. As for Kimihito, she calls him by his name once and then starts to casually call him Darling, just because. Hilariously her phone info for him has him labeled as "Darling-kun".
  • Friend to All Children: Ms. Smith is shown to be very kind and caring to children, as shown when she and M.O.N. rescue a bunch of extraspecies children from kidnappers in a flashback in chapter 20, and her interaction with Yuuhi in chapter 38 after her transformation into a zombie.
  • 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.
  • Laser-Guided Karma: After using Kimihito's sickness as an excuse to avoid paperwork and dump it on MON, she's left to take care of herself when she becomes sick.
  • Last Name Basis: She's only referred to as Ms. Smith in the manga and anime. If this piece of merchandising is canonical her full name is Kuroko Smith.
  • No Sense of Personal Space: In a number of chapters, she seems to enjoy getting up in Kimihito's face without warning. Whether because it unsettles him or because Smith has a more-than-professional interest is anyone's guess.
  • Offscreen Moment of Awesome: Implied as the reason she still has her job.
  • Pointy-Haired Boss: A huge part of Kimihito's problems comes from how irresponsible she is. However, there is a bit of a hint in chapter 10 that she does this because she's overworked already and never gets a raise for what she already does. Considering that we've seen her do all the things she rattles off, she may very well be telling the truth, and to her credit, when she's actually doing her job, she's pretty damn competent. The hunch was pretty much confirmed with Chapter 11.
    Ms. Smith: I have a lot of different jobs. Looking for home stays, working as the extra-species exchange ministry's, as security and surveillance, putting new experiments into practice...but I never get a raise for it. So I'm not gonna deal with this! Illegal entry? New species? Not my job! That's why I won't define "slime" as extra-species!
  • Psychotic Smirk: Sports a small, but very ominous, one when dealing with the orc leader.
  • Rapunzel Hair: Has waist-length black hair.
  • Reasonable Authority Figure: Zigzagged. She often forgets to mention new stuff to Kimihito regarding the homestay program, causing problems that could have been avoided, such as being reimbursed for food expenses for the girls. And though she tends to lump a lot of responsibility, and new monster girls, onto him, she does at least try to help get his house refurbished to accommodate the new guests, and helps take care of a lot of behind the scenes activities as well as the mundane paperwork.
  • 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: She even lampshades it when Kimihito reveals he has a leg fetish in an extra chapter and the Anime sure loves to focus on them when they are bare.
  • 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). It doesn't help that her name is still written in kanji.
  • 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.
  • Trademark Favorite Food: Coffee, specifically Kimihito's coffee. The cheap instant coffee during a meeting is regarded as awful, the cheap instant coffee at his house the best.
  • Victoria's Secret Compartment: For her tranquilizer gun.
  • Your Door Was Open: 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.

    The Racist Couple

Voiced by: Daiki Hamano (Man) & Ayaka Shimizu (Woman)

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.
  • Catchphrase: Usually a drawn out "Nasty!"
  • Dark-Skinned Blond: The girl looks like a ganguro.
  • Even Evil Has Standards: They may be colossal dicks, but the man freaks out and frantically tries to evade when a little kid wanders in front of his car.
  • 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. It's really only in the manga, though.
  • Hate Sink: Due to them being called "The Racist Couple," it's no surprise they are this of the manga and anime during their appearances.
  • 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.
    • In the final episode of the anime they apparently die in a car accident caused by Centorea. Their car blew up!
  • Not-So-Harmless Villain: The man upgrades from harmless, if annoying Hate Sink Jerkass to out-and-out villainy in chapter 16, in which he very nearly crosses the Moral Event Horizon in his attempted rape of Centorea. One can only hope he took the warning Rachnera gave him to heart...
  • 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.

    Bicycle Cop

Voiced by: Atsushi Kousaka

A local police officer that shows up every now and then.
  • Ascended Extra: Downplayed in the anime. While he still doesn't have a major role, he does make more appearances than he did in the manga.
  • By-the-Book Cop: His adherence to the rules would have gotten Papi deported had Ms. Smith not showed up.
  • Cowardly Lion: Scares easily, but usually tries to do his job anyway.
  • Recurring Extra: He makes sporadic appearances throughout the series.
  • Stop or I Will Shoot!: Almost shot Kimihito after he found him holding Lala's severed head in the park at night.

    Police Chief

A police officer that first appeared to deal with the orcs in chapter 11.

    Kasegi/The Director

Voiced by: Keiji Fujiwara

A Con Man looking to make money out of monster girls. Posed as a documentary filmmaker in order to get into the Kurusu household. Last seen getting arrested by Mon.
  • Asshole Victim: His Loophole Abuse of doing a documentary doesn't sit well with the girls after he starts asking rather personal questions, and then says if they attack him, they'd be in violation of the Interspecies Exchange Law that prohibits non-human beings from attacking humans and vice versa. Kimihito, being a human, doesn't have that same problem, so he hits the guy for them.
    • Later he complains about losing the money he could've made from the stuff created by the girls gathered at Kimihito's house. He then mentions having to collect some more thread to recoup his expenses, and complains to Rachnera to put all her silk in one spot. She responds by tying him up with it.
  • Bullying a Dragon: Really should have kept his opinion of Rachnera to himself.
  • Dangerously Genre Savvy: Lies to Kimihito about making a documentary of the interspecies exchange. Then repeatedly states that it's for a documentary when they protest rather personal questions such as if they wear underwear or asks for stuff the girls have around the house. Were it not for Suu reading his mind, he probably would have gotten away with it.
  • Depraved Dwarf: The anime makes it clear that he's a midget, and he's certainly depraved.
  • Engineered Public Confession: His real thoughts are broadcasted thanks to Suu's powers, and all pretenses of filming for science quickly fall down (he even refers to the girls as "extraspecies retards").
  • Loophole Abuse:
    • Japan's censorship laws apparently doesn't apply to monster girls.
    • When the monster girls get offended at stuff he asks them or requests, he continually reminds them that they'd be violating the law if they attack him. Fortunately Kimihito also uses this trope against the guy, hitting him in much the same manner as he did with the racist couple that continually insulted Miia.
  • No Name Given: Introduces himself as Kasegi at first, but that name turns out to be fake. This doesn't stop the English release from repeatedly referring to him as such in volume 4.
  • Solid Gold Poop: Was planning to make money by selling Papi's egg, Miia's cast off skin and Rachnera's web.
  • Super Human Trafficking: Bought Rachnera (or more accurately, the right to host her) from the Kunanzuki family.

    Ren Kunanzuki

The daughter of Rachnera's first host family. She tried - and failed - to adopt Rachnera back into her family.
  • The Atoner: She wanted to readopt Rachnera out of guilt for her parents selling her.
  • Determinator: Her response to everything that happens to her is to bring on the next challenge, such as repeatedly trying to eat Miia's latest dish despite passing out from the smell each time.
  • Innocently Insensitive: She has a bad habit of insulting people without actively trying to. Kimihito even refused to let her readopt Rachnera because she kept treating Rachnera like a challenge to overcome instead of an actual person.


A young girl staying at the same hospital Kimihito gets admitted to.

Monster Girls Living With Kimihito

    In General
Our Beloved Monster Girls Harem From Top To Bottom Clockwise: Rachnera, Suu, Papi, Miia, Centorea, Meroune

In General
  • Blonde, Brunette, Redhead: The first three girls, Centorea, Papi and Miia (though they actually debuted in the opposite order).
  • Clingy Jealous Girl: Miia is the most overt case, but most of the others have shown this to varying degrees.
  • Cute Monster Girl: Duh.
  • Does Not Know Her Own Strength: Everyone but Rachnera and Lala have difficulty holding their strength back, which often results in Kimihito being injured. When Lunacy strikes Miia, Papi, and Centorea 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 Meroune, Papi and Suu, and Centorea and Rachnera. This gets played up in the various date chapters.
    • Happens again in the vacation chapters, only with different combinations. This time, it's: Miia and Rachnera, Centorea and Papi, and Mero and Suu.
  • A Lizard Named "Liz": Their names are all indicators of their species, but not exact matches.
  • Ms. Fanservice: Nearly all girls.
  • My Significance Sense Is Tingling: When Rachnera arranges to move in, it cuts back to the house showing Miia, Centorea, Meroune, 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, but particularly Miia.
  • Pretty Freeloaders: They all live with Kimihito and usually have him do all the household chores and cook for them. Over time they try to do more work around the house, but their unusual bodies and just plain ineptness in some cases mean trying to do chores just makes more work. They can at least be pretty good at simple cleaning, as shown when they were preparing for the mothers to visit.
  • Rescue Romance: So far Kimihito 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.
  • Single Woman Seeks Good Man: Each of the girls 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 keeping 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.
    • Meroune: 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.
    • Lala: As a Made of Iron Butt Monkey, Kimihito's resilience, strength and determination to overcome death with or without her help got her attention. His compassion, kindness and selflessness for everyone clinched it, though.
  • 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" (which is then rendered as "Meroune Lorelai" in volumes 4, 5 & 8).
  • 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.
  • Tiny Guy, Huge Girl: Several of the girls dwarf Kimihito by size, generally through their full length (Miia, Mero) or through body mass (Centorea, Rachnera). Suu in adult mode is a more straightforward example.

Miia and her cuddling habit

Voiced by: Sora Amamiya

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.
  • Accidental Pervert: In Chapter 31, she accidentally grabs Kimihito's towel while they were in the onsen, exposing him to everyone. She's clearly sorry about it.
  • And Call Him George: Kimihito is constantly injured by the affections of Miia, who constricts him hard with her tail every time she hugs him.
  • Art Evolution: When the series started, Miia's scales extended up around her "hips" in the rear, but eventually these scales were scaled back to give her a more human-looking "butt." The question remains if it serves a function aside from being attractive and being something to sit on.
  • Bare Your Midriff: Not to the extent as Mero, but she finds a way to do this pretty often: she's outwardly stated that her hips are her best feature; they're kept shapely from the swaying movement that comes with having a snake tail. Chapter 27 displays that this is common amongst Lamia.
  • Be Careful What You Wish For: Wanted to be princess-carried by Kimihito in Chapter 12. Cerea points out that it would be impossible (due to her weight). She gets her wish anyway when he has to rescue her from the bottom of the pool.
  • 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. Centorea calls bull, but Papi buys it.
  • Characterization Marches On: Miia came off as much more ditzy when she had Kimihito all to herself (particularly in her complete inability to recognize when her tail is squeezing too hard), with her temper becoming a more prominent trait with each new girl in the house.
  • Clingy Jealous Girl: She really hates it when other girls get close to her "Darling". It gets worse with each new "rival".
  • Cordon Bleugh Chef: Miia has an 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 later, she added peanut butter to miso soup on the basis that she thinks it looks like miso. Just one of the reasons she's the Lethal Chef in residence.
  • Cuddle Bug: Miia's cold-blooded, and likes snuggling with warm-blooded people (usually Kimihito) to get heated up. Unfortunately, she tends to forget that she's descended from animals that literally crush prey to death doing this and needs to hold back her strength, much to Kimihito's pain and dismay.
  • Cute Little Fangs: Really prominent when her cuteness factor is high. Her open mouth is usually drawn with a single upper canine visible.
  • Disappeared Dad: An omake reveals her human father ran off soon after being forced into impregnating her mother (he simply hated snakes too much to stick around, the lamia's sexual skills and beauty not being enough to keep him there). This does not appear to have caused Miia any real problems though, as there is no evidence that lamia fathers are expected to play any major role in their daughter's lives (since they traditionally end up having a lot of daughters).
  • 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. Then there's the shedding scene. Pop goes the spinal column. You could make a drinking game of the number of times Kimihito has been accidentally hurt by her.
  • Evil Is Hammy: As "Cobra Miia" in Chapter 32.
  • Exotic Eye Designs: 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.
  • Extreme Omnivore: She can eat her own cooking without any negative effects, partly because, as a carnivore, her sense of taste is so weak compared to most of the cast.
  • Fangirl: Of the Metal Gear series, if her frequent cosplays as Solid and Naked Snake are any indication.
    • Well, she IS a snake person after all.
  • 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 in Kimihito's harem, and the only redhead in it.
  • 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 (most of her internal organs are assumed to be in her human torso, leaving her snake part to being almost entirely muscle and bone). 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.
  • Godiva Hair: In the anime (the manga freely displays nipples), her hair is used to cover her breasts occasionally.
  • Hair Decorations: She wears a pair of D-shaped hair clips. They even serve as her emblem in the anime.
  • Hoist By Her Own Petard: Drastically lowers the temperature of the room she's currently in to try making Mero 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 Badass hero complete with Hand Wraps Of Awesome, probably takes the cake.
  • Immodest Orgasm: And before you're even ten pages into the story, too.
  • In Love with the Mark: While she's not an assassin, her mother's chapter reveals she was sent out on a sinister mission. Namely to capture a human male so that he could become the community's sex slave. However, Miia decides fairly quickly that she wants Kimihito for herself.
  • Lethal Chef:
    • Her cooking is the stuff a chef's nightmare's nightmares have nightmares about. 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, Meroune 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 Mero's subconscious opinion of the meal is - i.e it's an 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.
    • In Chapter 26, the smell of Miia's cooking alone (which Cerea referred to as Miia's "something") was enough to cause Ren to pass out. Multiple times!
  • Limited Wardrobe: She's notable in that she's an aversion. Compared to the other girls, she has quite a few outfits in a variety of styles. One chapter reveals she orders a lot of clothes online.
  • 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 moderately heated swimming pool, over time she'll become sluggish as she requires a relatively high water temperature.
  • Lovable Sex Maniac: She really wants to get into Kimihito's pants. She even tried to strip Kimihito while he was sick. When her mother drugs him with a powerful aphrodisiac during her visit, her initial terror quickly fades into lustful anticipation. Amusingly, the same chapter also reveals that her sexual mores are practically prudish by her culture's standards.
  • Marshmallow Hell: Really likes doing this to Kimihito. Considering how tight her grip can get, the 'hell' part of it usually becomes the dominant attribute...
  • Naughty Nurse Outfit: Wastes no time donning one after finding out Kimihito's sick, and is chomping at the bit to administer 'treatment'.
  • 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.
  • One-Note Cook: Boiled eggs are the one dish she can cook without ruining.
  • 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. It's a human tongue at first glance, but it's actually forked at the end like an ordinary snake's.
  • Pointed Ears: Just one more bit of divergence from the human body type.
  • Prehensile Tail: Miia's tail is quite dexterous, capable of gripping and manipulating items like a zipper.
  • Rapunzel Hair: It goes past her waist.
  • Shameless Fanservice Girl: She's very, very intent on showing Kimihito her goods to try and tempt him into actually making a move. 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.
  • Snake People: Duh.
  • Snakes Are Sexy: And she exploits it for all it's worth.
  • Strong Family Resemblance: She looks a lot like her mother.
  • Supernatural Gold Eyes: A lamia girl with amber eyes.
  • Super Strength: She can crumple metal in her coils, seemingly not even realizing it when under the effect of the full moon. 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. Hilariously, the chapter with her mother reveals that she's actually rather conservative about seducing men by lamia standards.
  • Trademark Favorite Food: Miia really loves boiled eggs.
  • Tranquil Fury: When she sees Kimihito with a hoof-shaped bruise on his face, she shoots the culprit a Death Glare that actually manages to get the centaur scared and speaks in a horrifyingly calm voice.
    Miia: Humans and other species may not harm each other.
  • 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. When she tried swimming in Mero's (non-heated) pool, she froze up and dropped like a stone, almost drowning.
  • Why Did It Have to Be Snakes?: Miia is terrified of severed heads, and therefore does not react well to Lala the dullahan.
    **An aversion to Truth in Television but doubles with Fridge Logic given her animal motif. Aversion, because USUALLY a snake will try to devour prey head-first; the maneuver's purpose is to suffocate the victim, should it still be alive after being poisoned/wrangled and to minimize injury to the snake. On the other hand, heads, or actually skulls are the hardest part to digest for reptilian, especially snakes. There's been numerous cases of snakes dying from having their prey's skull lodged on their mouth, pressing the windpipe.
  • Your Size May Vary: The length of her tail, which varies from being about twice the length of her upper half to closer to twenty feet, though according to Chapter 17 her body is around eight meters (just over twenty-six feet) long in total. The official measurements at the end of volume 1 state her head to tail length to be "over seven meters."

Papi flies wherever she pleases

Voiced by: Ari Ozawa

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.
  • 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 Papi's hands not being strong enough to hold people and Suu being slippery she can't do anything but watch her fall.
  • 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.
  • 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!: Has a short attention span that lasts for mere seconds. 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.
  • Catchphrase: In the English manga, she's fond of "no pro", as in "no problem".
  • Comically Missing the Point: She 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.
    • When the aforementioned three girls and Mero are watching what appears to be Kimihito's date with Ms. Smith in a cafe, Papi is only focused on how all the waitresses look like Mero.
  • The Ditz: She's a complete idiot, gets distracted very easily and is extremely forgetful.
  • Erotic Eating: Her introduction chapter has her sucking on an ice-stick while Kimihito holds it for her in as unsubtle a way as can be, complete with doing it in public and having some splattered all over her.
    Kimihito: This looks rather… inappropriate…
    Passersby: (Stage whispering among themselves) What are they doing?/ Don't look!/ He must be doing it on purpose./ I bet he's a perv.
    Papi: Awww, I'm all sticky!
  • Extreme Omnivore: One of the ending notes explains that Papi has no sense of taste and will eat anything. She only ever describes food as "good" or "really good". Miia's cooking and vegetables being the exception.
  • Femme Fatalons: Her wings have exposed thumbs like a bat each ending in a sharp black claw.
  • Forgetful Jones: She tends to forget things almost right away. The few things she does retain are usually misremembered.
  • Friend to All Children: She's very good with children.
  • Giant Flyer: While she's the smallest member of the household, she's still bigger than your average bird, with a wingspan of 4 meters, or 13 feet.
  • 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.
  • The 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.
  • Innate Night Vision: Averted hard; she has terrible night vision (like most non-owl birds).
  • Innocent Fanservice Girl: Papi has no concept of modesty, as she dives into a public fountain naked thinking it's a bird bath.
  • Kindhearted Simpleton: She's a birdbrain, but she's good-natured, friendly and quite a Mama Bear to children.
  • Logical Weakness: If her wings are too wet, she becomes unable to fly.
  • Loophole Abuse: Papi tends to forget things whenever she takes three steps. However, if she avoids taking three steps for a while, such as through flying or being carried around, she can keep her train of thought much better.
  • Malaproper: When the police and Ms. Smith are looking for her to have her returned to her host family or deported, Papi tries to explain her situation to Kimihito. Unfortunately, instead of saying "deported," she says "deflowered" (according to the fan manga translation), "aborted" (according to the official manga translation), or "incest" (according to the anime translation).
  • Male Gaze: In one of the omakes when Miia, Centorea, and Papi are comparing their best features, Papi is declared the "butt" girl for having the best (humanlike) backside. It's plush too, as Kimihito (accidentally) found out.
  • Mama Bear: It's noted that her motherly instincts are really strong. She ends up switching between this and Big Sister Instinct depending on the situation. The "mother hen" pun is more or less cemented in chapter 33 when she bonds with a bunch of baby chickens.
  • Mundane Utility: Her wings make for a great feather duster.
  • Older Than She Looks: 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.
  • OOC Is Serious Business: Kimihito freaks out when she's actually able to remember and explain the conflict with her mother (though it turns out to be one big misunderstanding).
  • Perpetual Molt: She tends to drop feathers whenever she takes flight.
  • Real Men Eat Meat: Apart from the ice cream in her introduction, Papi has a preference for meat, and in most food scenes she's violently biting down on a large slab of the stuff.
  • Shared Family Quirks: Her mother's attention span and short term memory are arguably worse than Papi's.
  • Slapstick Knows No Gender: Of all the girls living with Kimihito, Papi gets the most injuries. She gets a door slammed on her head, she gets a Tail Slap in the face from Mero, and she always crashes into things if she flies in the dark.
  • 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.
    • The official English translation ups this a hundred fold by making it 3 million dollars instead. note 
  • Strong Family Resemblance: Without her bleached hair, tan and makeup, Papi's mom looks almost identical to Papi. This becomes a plot point when the letter from Papi's mother contains what appears to be Papi lying naked with an unknown man.
  • Third-Person Person: Delves into this sometimes, like when she first introduces herself.
    Papi: Papi's Papi the Harpy!
  • 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
Cerea's got back

Voiced by: Natsuki Aikawa

A centaur and the third girl to move in with Kimihito. Very prim and proper, as expected from a self-proclaimed knight.
  • A-Cup Angst: Despite being quite endowed herself, Centorea expressed discontent when she noticed Cathyl was bustier than her.
  • 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 with it 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.
  • Action Girl: A courageous knight, competent with sword and bow.
  • 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.
  • Ass Kicks You: Accidentally smashing Kimihito with her horse torso is her most common method of inflicting Amusing Injuries on him. She has a tendency to crash into things any time she needs to move backwards or sideways, too.
  • Badass Adorable: She IS a brave and competent warrior, but her insecurities, Imagine Spot with Kimihito, and her Adorkable image make her this.
  • 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 helped get the entire group banned from a restaurant once. This is probably based on the behavior of real life horses, who will instinctively chow down on whatever food is in front of them until something stops them or they run out.
  • Blade on a Stick: She knows how to use lances, including jousting lances.
  • Bow and Sword, in Accord: Although the bow is only seen once. A bow is an odd weapon for a knight, but makes sense for a centaur knight.
  • Clingy Jealous Girl: She may think of it as beneath her, but deep down she's just as clingy to Kimihito 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 Kimihito 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. Played with following the revelation that her desire to serve a "master" is at least partly rooted in not wanting to engage in her people's frankly barbaric breeding practices. She had good reason to want to find a "master" ASAP!
  • 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.
  • D-Cup Distress: Downplayed. She doesn't show much resentment towards her ample chest, but she gets embarrassed whenever people bring attention to it. She also is utterly incapable of finding a bra that will survive her Gag Boobs, partly because she's reluctant to admit her exact size and makes them sound smaller than they really are.
  • Expressive Ears: In chapter 25 they wriggle as she's eating carrots given to her.
  • Gag Boobs: They're massive (a 103 I bra was tried and found too small, as was one big enough that Papi and Suu were able to use the cups for hats) 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.
  • Gainaxing: Her breasts bounce a lot thanks to their size and her lack of a bra. This actually turns out to be a problem in Chapter 29, as the bouncing keeps throwing off her aim while jousting.
  • 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. And when everyone else was either frightened or grumpy when the butler fish asked them to "save the princess," Cerea instantly perked up.
  • Gilligan Cut: In chapter 35, she finds it shameful that Miia gives in to the massage of the eel mermaids, and declares that she would never submit like this. Surely enough, she's reduced to a moaning mess one panel later. The very next chapter features something similar with giant sea anemones.
  • 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. Her aim when jousting improves greatly when she starts wearing a bra. Too bad it wasn't big enough.
  • Hair of Gold, Heart of Gold: She's an incredibly honorable and chivalrous self-proclaimed knight.
  • Half-Human Hybrid: Turns out that, while Centorea's mother is a centaur, her biological father was human.
  • 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.
  • Honor Before Reason: Displays this occasionally, such as how she first felt about Rachnera. Though she is still pretty sensible for an honor-bound knight.
  • Hypocritical Humor: Generally, when she tries to act like she's too good for the situation, she'll still fall victim to it. Examples include succumbing to a Lunacy-induced sex craze right after saying that she wouldn't, getting caught in one of Rachnera's traps in the middle of criticizing Miia for not being alert enough, and the two Gilligan Cut events mentioned above.
  • Innocent Blue Eyes: Blue eyes for a good and honorable knight.
  • 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.
  • Knight in Shining Armor: Tries very hard to be this. Occasionally she succeeds, but more often she ends up as a sympathetic Lord Error-Prone.
  • Lady of War: Tries to be one. It works as long as she is emotionally stable, which in a harem comedy series is not that often.
  • Large Ham: Has a habit of being melodramatic. She even compares her meeting with Kimihito to the meeting of Hercules and Chiron.
  • Limited Wardrobe: Aside from the occasional swimsuit, Centorea is always seen wearing a white shirt with a horse-sized black skirt.
  • Luminescent Blush: Chapter 29 when she sees exactly what Kimihito brought to give her an edge over her mother: A bra.
  • 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. And in Chapter 31, she's the only one who suggests a plan to save the hot springs resort that's actually quite sensible. In general, she's the reasonable girl of the lot, who doesn't try to push Kimihito around as much as the others.
  • Our Centaurs Are Different: Apparently they're European-styled knights.
  • Phenotype Stereotype: Blonde-haired, blue-eyed girl? Check. Foreigner? Check (she's most likely from Europe given her knightly background).
  • Proud Warrior Race Girl: Her race is this in general going by her stories of centaur knighthood. She herself is a downplayed version of this trope.
  • Rapunzel Hair: Her ponytail is nearly as long as her body.
  • Reluctant Fanservice Girl: She really does try to dress modestly, but is frequently either giving Kimihito Marshmallow Hell, being groped by Kimihoto in accidents, or losing her top completely and revealing her breasts. Embarrassment tends to happen after each event.
  • Strong Family Resemblance: Aside from her hairstyle, you'd have a hard time telling her apart from her mother.
  • Subordinate Excuse: She calls herself Kimihito's servant, but her feelings clearly go beyond that.
  • Thanks for the Mammaries: Pretty regularly, especially whenever Kimihito has to hitch a ride and needs a place to... hold on.
  • Token Wholesome: Centorea actually dresses and acts very properly. It's just that being stacked like a snow fort makes modesty... difficult. The only person who's even more wholesome is Lala.
  • Tomboyish Ponytail: She ties her hair in a ponytail and she works hard to be a strong and chivalrous knight.
  • Trademark Favorite Food: Carrots. Recently red carrots have been her favorite, though it's pointed out she's embarrassed about being around others as she indulges.
  • Weapon of Choice: While she knows how to use a variety of weapons, her preferred weapon is her (fake) sword.
  • 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.

Suu floats his boat

Voiced by: Mayuka Nomura

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.
  • Acquired Situational Narcissism: When Suu is told she's a VIP, she acts much bossier than she usually does, such as demanding a piggy back ride and requesting drinks from her bodyguards.
  • Alien Hair: In her humanoid form, she has a mass of green "hair" made of slime.
  • 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. Then there was the time she molested Draco, and judging from her facial expression and the way she reacted to Draco's protests, it seemed she knew full well what she was doing.
  • 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. And when all the sea water she soaks up in Chapter 36 gives her a massive maturity boost, she immediately goes after Oct and Rachnera for her own amusement.
  • 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 when 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. Yet the girls never treat the fondling assaults as more than an annoyance.
  • Blob Monster: She is a slime.
  • Breast Expansion: Absorbing plenty of water and becoming "well-fed" causes her to take on an older appearance, including going from mostly-flat to stacked.
  • 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.
  • Character Development: As in, at some point she actually starts to be an independent character that doesn't just mimic other people's actions. Though whether she gains maturity as the story goes on or she's just very good at hiding it is sometimes unclear.
  • Comically Missing the Point: Could explain her actions in chapter 36. The now MILF Suu comes upon Oct and Rachnera essentially in a bondage war to get each other off to the point of defeat. Rachnera asks for "help" and Suu "helps" them both reach orgasm. Further evidence is when Rachnera and Oct are complimenting each other's skills and Suu asks for their opinion on her techniques.
  • Dirty Mind-Reading: Uses this on the director when he's filming the girls and asking very inappropriate questions for a documentary such as if they wear underwear. Were it not for her doing this on him, he probably would have gotten away with it, all under the guise of "making a documentary on the homestay program".
  • Discreet Dining Disposal: Miia and Papi feed Suu their plates full of vegetables they don't want to eat, much to Kimihito's chagrin.
  • 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.
    • She outright states that she can eat anything as long as her body can digest it, encouraging Kimihito not to waste money buying actual food for her.
    • 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.
    • Disposing of unwanted food is one of her "jobs" in the house and she is quite proud of it.
  • 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.
  • Hand-Hiding Sleeves: When she's in her normal size, the sleeves of her raincoat cover her hands.
  • 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.
  • The Illegal: Her race is a type of liminal currently not fully classified under the Accord and it's assumed she arrived in Japan by some sort of illegal entry. However, Ms. Smith decides Suu is not her problem and lets her live with Kimihito.
  • The 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.
  • Kryptonite-Proof Suit: Gets a waterproof wetsuit in chapter 35 when she needs to enter the water. However, it doesn't cover her head, which Kimihito realizes just a little too late (fortunately, this only results in Breast Expansion).
  • Limited Wardrobe: The only clothes Suu ever wears is a raincoat with boots. Justified, since her liquid body would make nearly all clothes unusable for her. The anime even has a short that shows Suu's closet is filled with nothing but identical yellow raincoats.
  • 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.
    • Off another tangent, she is also susceptible to freezing temperatures due to her liquid body.
  • Lovable 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.
  • Marry Them All: She openly supports this option. However, if Kimihito only chose one she believes she is the most worthy (though it's not clear how much she understands what being married means).
  • Morphic Resonance: Regardless of whether she's in blob, child, or adult form, or mimicking another person or object, she always has her antenna, though she can at least conceal it when forming a perfect imitation of someone else.
  • 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.
    • In chapter 30 we get her newest revealed ability, being able to control her body's digestive ability to the extent that she can remove the skins of vegetables and fruits and spit them out intact, making her very helpful for cooking.
  • 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.
  • Personality Powers: As a Slime Girl, anything she consumes will be shown through her attitude and form. She really makes the phrase "you are what you eat" literal in a sense.
    • Chapter 20: Suu falling down into a radioactive fertilizer from the dump site supercharges her size in proportion to Godzilla.
    • Chapter 25: shows her speech pattern filled with toxic Trash Talk after ingesting poisonous mushrooms in the forest.
    • Chapter 31: has her ingesting mineral water, which gives her a professional secretary demeanor.
    • Chapter 36: After absorbing nutrients from the Sea she becomes, essentially, a MILF in appearance and personality.
  • One-Winged Angel: In the anime's adaptation of Chapter 20, when Suu makes her kaiju-sized debut she turns her hair tentacles into a tail and jagged dorsal fins, and even spits a beam of energy.
  • 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.
    • She also seems to randomly attack Rachnee at least once a day even if she hasn't been splashed or gotten wet. Rachnee's continued use of bondage on the other girls likewise seems to be her way of trying to find new ways to resist these attacks. Given that Suu typically emits a heart emote or two when she dives Rachnee, she might just see it as an on-going game.
  • 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.
  • Slime Girl: A shining, or rather slimy, example.
  • Smart People Wear Glasses: When she gets an intelligence boost after soaking in mineral-enriched water, she suddenly alters her face to look like she's wearing glasses.
  • 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.
  • Third-Person Person: Once she starts talking normally, she refers to herself in third person.
  • 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.
  • Voluntary Shapeshifting: Suu manages to be an even better shapeshifter than Doppel and Ninetei. While Doppel can change her clothes but is limited to transforming into humanoids, and Ninetei can transform into anything but can't change her clothes, Suu can do all of that and more. She can shapeshift herself around other people to become their clothes, or even transform into functioning arms and legs.
  • You Gotta Have Blue Hair: Green. 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.

    Meroune Lorelei
Mero makes a splash

Voiced by: Haruka Yamazaki

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 Meroune 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.
  • Beware the Nice Ones: Normally Mero is the very image of polite and gentle, but she crowned Papi with a wicked tail slap in an unconscious effort to protect The Couch That Turns People Into Mush from the harpy's talons.
  • Bi the Way: In the official English version, she states that she's okay being the mistress to Miia's wife, as long as Miia overlooks the affair ...or permits the occasional menage a trois. And she proceeds to grope Miia to emphasize this.
  • Character Development: When first introduced, Mero has an unhealthy fixation on "tragic romance". Over the course of the series, she has endured the possibility of all her fantasies becoming a reality and realized that while they make for nice fantasies, she would be heartbroken if they actually happened. By chapter 37, she has mostly realized that what she really wants is to marry Kimihito and have a normal, happy life (though the idea of Kimihito having a mistress, namely Miia, still sounds good to her).
  • Character Tics: Clasping her webbed hands together. Suu also does it when imitating her.
  • Charm Person: Further hinting at royal origins, she possesses a compelling regal aura capable of making people genuflect when speaking. She also uses it to inspire people feeling down about themselves.
  • 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.
  • Don't Call Me Sir: Once she's revealed to be a princess, she becomes very uncomfortable about Kimihito's and the other girls' (mainly Centorea's) change of attitude towards her and asks them to not treat her any different only because they now know she's royalty.
  • Drama Queen: A bit, usually whenever she gets starry-eyed over the prospect of tragedy.
  • Elegant Gothic Lolita: This is how she dresses, although it's noticeably more Stripperiffic than the norm.
  • Everything's Better with Princesses: Centorea and other people she meets certainly get a "royalty" vibe from her, and she does seem to know an awful lot about knights and nobles. Confirmed in Chapter 34.
  • 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?!
    Meroune: Oh, don't worry. The feeling...... is mutual.
  • Expressive Ears: They drooped when she took a bite of Miia's cooking.
  • Graceful in Their Element: Requires a wheelchair to move around on land, but put her in the water and she outstrips the greatest human swimmer. The gym chapter stresses this by letting her show off some impressive flips and turns.
  • Hammerspace: Keeps a large, heavy-looking conch shell ...somewhere that she whips out to smack people sometimes: Kimihito, Sebastian and Potemkin have all been on the receiving end at some point.
  • Heroic Sacrifice: Almost ends up making one in chapter 37, in order to save Kimihito from drowning. She gives him CPR underwater using the air from her swim bladder, in the process giving up her ability to control her bouyancy. Her tail was heavily damaged from rubble, preventing her from swimming effectively, and she was almost sucked by a current into a grid of spikes. Fortunately, Kimihito managed to use leftover strings from Rachnera to pull her up along with himself being pulled by Miia.
  • Ignored Epiphany: At first it seems like the events of chapter 37 have finally snapped Mero out of her "tragic romance" fantasy when she realises how losing in love would actually feel... But no, she just wants to flip the script now, with Miia being the runner up in the tragedy instead, much to the latter's indignation.
  • Innocently Insensitive: Sometimes. She's sincere in her compliments, it's just her choice of words are usually... poor.
    Meroune: There, there, Miia-sama was amazing as well. You swam just like an eel! (Totally innocent.)
  • Keigo: Always speaks very politely, which was part of Cerea's suspicion toward her background.
  • Large Ham: Not always, but when she lapses into "tragic heroine" mode she can rival Cerea.
  • Limited Wardrobe: She's typically seen either in a Gothic Lolita maid-style outfit or a bikini. A look inside her wardrobe in chapter 26 reveals she has a number of clothes, but they're all Gothic Lolita (and according to chapter 23, only her maid-style outfit is suitable for a funeral).
  • 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.
    • Her skin needs to be wet so she can breathe on land, meaning if the air becomes too hot, her skin will dry out, making it hard for her to breathe. On the flipside, if the air is so cold it's freezing, her skin will get frozen, which also makes it hard for her to breathe, if not worse.
  • 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.
  • Meaningful Name: Her middle name, Lorelei, refers to a famous siren from German folklore. Her surname, du Neptune, refers to the Roman god of the sea.
  • 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.
  • 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.
  • Moment Killer: She accidentally does this to Miia and Kimihito in Chapter 19.
  • 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, ultimately changing her mind entirely in Chapter 37. By which we mean wanting Miia to be the runner up instead.
  • Nice Girl: Insensitive moments aside, she is unfailingly kind and polite to everyone she meets.
  • Nightmare Fetishist: 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." 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.
    • She eventually becomes a Deconstruction. Every time one of her fantasies seems like it might come true, she very abruptly realizes how emotionally painful it is and that she doesn't actually want it.
  • Ojou: In the "hot springs dating" incident, she mentions being independently wealthy and able to financially support her partner. It's later revealed she's not only rich, she's a princess.
  • Ojou Ringlets: Has straight hair that curls into ringlets, which befits her Elegant Gothic Lolita attire and princess-y behavior. And she really is a princess.
  • 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. And that's just Mero: chapter 35 shows that merfolk come in all shapes and sizes, some of them being straight-up weird. One female merperson has a human body and a fish for a head. An entire fish.
  • Overly Long Name: Chapter 35 reveals her full name is Meroune Lorelei du Neptune.
  • Perky Goth: Dresses in the Elegant Gothic Lolita style and is a bit of a Nightmare Fetishist, but has a very warm personality overall.
  • Princess Classic: Besides her bizarre wish for tragedy, she's a polite and graceful beautiful lady with a "royal aura". She's later confirmed to be a real princess.
  • Princesses Prefer Pink: She has long pink hair and a pink tail, contributing to her princess-y looks and serving as hints that she really is a princess.
  • Rapunzel Hair: It goes past her waist.
  • Really Royalty Reveal: She's been long thought to have a "royal aura", and it turns out she really is royalty. And a princess no less!
  • Rose-Haired Sweetie: Very princess-y and refined, whatever her bizarre interests.
  • Shipper on Deck: She wants anyone but herself to be with Kimihito (solely so she can be the mistress), primarily Miia as she was the only one to openly acknowledge being interested in him.
    • By chapter 37, she's realized that she actually does want to be with Kimihito - but she's still on board with Miia getting together with him, so that Miia can be the mistress, the girl he's unable to forget.
  • Skinship Grope: Inflicts this on Miia at the end of her debut chapter while the two are reconciling.
  • Someone to Remember Him By: After realizing that netorare 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.
  • Star-Crossed Lovers: She professes to get excited about being separated from Kimihito in chapter 35, but underneath apparently realizes how painful it would be.
  • Thinks Like a Romance Novel: Wants to experience a "tragic love" like in the original Little Mermaid story, including turning into sea foam.
  • 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.
  • 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. However, she changes her mind by chapter 37, deciding that she wants a requited love after all.
  • Visual Pun: Mermaid. Get it?
  • Wardrobe Malfunction: Mermaids secrete a slime to keep themselves moist. The result causes this to happen when she wears clothing not designed around avoiding this.
  • Waterfall Puke: Afflicted with this when she starts getting chlorine poisoning from the pool.
  • You Gotta Have Blue Hair: She has pink hair.

    Rachnera Arachnera
Rachnee catches her prey

Voiced by: Sakura Nakamura

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: Put it this way: Rachnera is to guerrilla fighters or covert operators as Centorea is to knights - she's an ambush predator. She's also particularly good with her webs: Miia jumps at her when she first shows up and tries to put the moves on Kimihito, and is completely restrained in webbing a panel later with Rachnee ignoring her outright. She can even catch by surprise Centorea, the only one with a warrior background.
  • Affectionate Nickname:
    • The household starts calling her "Rachnee" as soon as she moves in. In Japanese it's written "Raku-nee", as in "big sister Rach".
    • In the official English release, she's known as "Spidey" as well.
    • She calls Kimihito "Honey."
  • Ambiguously Bi: Likes to put the girls in bondage as much as she does Kimihito. She also admits, while drunk, that she did this with Ren Kunanzuki when she lived with her. Then there's the time she had her way with Lilith in Chapter 21, or her amicable relationship with Oct, when they casually discuss how much they enjoyed getting tied up / tentacled.
  • 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.
  • Art Evolution: Rachnera' pedipalps have over time been drawn to look more like the legs of a human (albeit missing the feet and covered in chitin). This is certainly attractive, but has led some to say it makes her look more like a human with a giant spider stuck to her rear (ignoring the various spider features of her humanoid portion).
  • Bad Dreams: She still has nightmares about the time she hurt Ren.
  • 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 breathe out her mouth. It's not clear if that's actually true, but the fact her mouth moves when she speaks implies she can exhale past her vocal cords and lips.
    • Like spiders, Rachnee gets drunk on caffeine.
    • Her webgame profile from the official website reveals that she only weighs 82 kilos (180 pounds), despite her massive size. In Chapter 17, when some of the girls had learned that they were overweight from a combination of overeating Kimihito's cooking and not being able to exercise much without Kimihito's presence, she proudly says that she doesn't need to go to the new Extraspecies gym like they do.
  • Brains and Bondage: Easily the most clever and level-headed of Kimihito's harem (most of the time), and the most careful with her strength. The bondage part is obvious.
  • Broken Bird: 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.
  • 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.
  • Bullying a Dragon: She tends to be the "Dragon" in this case.
  • Can't Hold Her Liquor: Strange example, in that Rachnera doesn't get drunk on alcohol, she gets drunk on caffeine. That being said, she gets very tipsy after only one cup of black coffee.
  • Casual Kink: Really enjoys tying people up much like a dominatrix would. And she enjoys testing new methods on the other girls.
  • Catchphrase: The English manga gave her the descriptive phrase "itsy-bitsy", referring to the nursery rhyme "The Itsy-Bitsy Spider".
  • Contralto of Danger: In the anime, she has the deepest voice of the monster girls seen thus far.
  • 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.
  • Deadpan Snarker: To the point of mocking the use of honorifics when addressing her.
  • Does Not Know Her Own Strength: An explicit aversion, having realized the potential dangers of her body from her last host family. Bondage aside, she's never actually injured Kimihito (even while drunk), while the other girls regularly put him on death's door.
  • Drunk on Milk: Spiders get drunk off of caffeine. Rachnera is no exception.
  • Even the Girls Want Her: A variation, as Lilith becomes totally hooked on her incredible bondage skills. And Mero enthusiastically serves as a test subject for Rachnee's "training" in an extra chapter.
  • Extra Eyes: She has six eyes. It doesn't come off as creepy...usually.
  • Fangs Are Evil: At first they come off this way, but eventually Rachnera's mood improves and they become Cute Little Fangs. Can snap right back if she puts on her Nightmare Face, though.
  • 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.
  • The Fettered: Perhaps ironically for a dominatrix, Rachnera is the girl with the most restraint towards Kimihito with regards to her strength and movements. But then, any good Dom knows that they should only go so far, and would never inflict lasting harm on their Sub.
  • 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: She hates humans and refuses to trust them because her original host family sold her off into slavery.
  • 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.
    • In chapter 30, Kimihito notes that, despite her Freakiness Shame, she's the only one who hasn't accidentally injured him before. That particular accident with Ren Kunanzuki has taught her the importance of being gentle with humans. As for Rachnera's response to Kimihito's remark about her gentleness, it was effectively Instant Seduction.
  • 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.
    Rachnera: (drunk) You don't worry about the little things, Honey. No, you don't worry about the big things either. Honey doesn't pay too much mind to anyone... Everyone's equal. Everyone's the same. That's why it's so easy to get along with you.
  • Hypocrite: Heavily implied, if not outright stated by Lilith; Rachnera's cold outer exterior is meant to hide a deeply hurting individual. For as much as Rachnera looks down on people who hide their true nature behind a mask, she herself wears one of tough cynicism.
  • 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, aside from Lala, none of the monster girls he lives with have normal human legs if they have legs at all...).
  • In Vino Veritas: She's apparently more forthcoming with her feelings when sloshed.
  • 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 him die peacefully 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. She's shown to be just as embarrassed and ashamed of it afterward as the rest of the girls.
  • 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.
    • Rachnee has very little tolerance to extreme temperatures, hot or cold.
  • Lovable Sex Maniac: More than any of the other girls she will try to jump Kimihito whenever she has the opportunity, even if she has an audience (unlike Miia).
  • Made a Slave: She was sold off into slavery by her original host family.
  • 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". She does it for fun at other times as well.
  • Modesty Bedsheet: Utterly subverted as she doesn't even use a bedsheet, she sleeps on a silk hammock in the glorious nude.
    • In fact, the anime shorts have shown that when she's alone in her room she even reads in the nude.
  • Monochromatic Eyes: Her eyes are pure red, lending to her creepy appearance.
  • Mundane Utility: An arachne's silk developed to catch prey and assist in climbing, but Rachnera also uses hers to make clothing, dolls, and thread phones, to bundle up things when packing, and (of course) for bondage techniques. Additionally, her claws (developed to dispatch prey items) make excellent letter openers.
  • Nightmare Face: She can don a truly impressive one. If the text font is anything to go by, she also puts on a voice to match.
  • 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. It comes in especially handy with the "humans are forbidden from harming extra-species, and vice-versa" law that's in effect; scaring away a would-be attacker isn't technically harming him, after all...
  • 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.
  • Only Sane Woman: Bondage aside, she is more level-headed (and less prone to flights of fancy) than Centorea, and never joins in squabbles over Kimihito.
  • 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.
    • This was also used against the Jerkasses in Chapter 16 that attempted to rape Centorea when they knew she could not fight back.
  • Peek-a-Bangs: Sometimes, but not always. It usually happens when she's being especially standoffish or cynical.
  • Razor Floss: One of the many applications she has for her silk.
  • Repetitive Name: Rachnera Arachnera.
  • Sarcastic Devotee: Snarky, sharp-tongued, cynical, and biting in her criticism. Her love for Kimihito is as strong as that of any other member of the harem.
  • 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.
    • Ten if you count the spider pedipalps that prolong her human thighs.
  • Sleep Cute: While Kimihito doesn't fall asleep himself, it is quite cute how Rachnera falls asleep while giving him a multi-limbed hug.
  • 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.
  • Super Speed: Faster than all of the girls, at least.
  • Sure, Let's Go with That: When Oct wants to know whether she'd set up the trap she catches the scylla in because she'd anticipated the whole situation in advance. She'd actually put it out just to mess with her teammates.
  • 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 with or without consent, 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.
  • Unreliable Narrator: Her initial recount of her Freudian Excuse seemed to imply a lot more malice on the part of her host family, in that they pawned her off to the director because they were disgusted by her appearance and didn't want to deal with her. It's later revealed that while the family may have been off-put and intimidated by her, they only put their foot down when Rachnera accidentally gave their daughter a slash across the face with her claws. Furthermore, they were under the impression that the director worked for the exchange program and would transfer her to a new foster home. They (or at least Ren) were appalled when they found out what happened to Rachnera and sent Ren to try and start over.
  • What the Hell, Hero?: In chapter 30, she's the only one to pick up on Kimihito just taking all the girls' abuse for the sake of potential marriage, and criticizes him for putting his life at risk.
  • You Gotta Have Blue Hair: Light lavender. Lends well to her "dark" appearance.

Lala owns your soul

Voiced by: Ai Kakuma

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.

Because she's introduced very late into the story, and because several significant reveals are linked directly to her, Lala is a Walking Spoiler. You have been warned.

  • A Day in the Limelight: Lala gets this in Chapter 38, as the plotline focuses on her and a terminally ill girl in a hospital.
  • Adorkable: Some of her spiels of self-grandeur are often humorously over the top, and she's unsure of how to interact with young children.
  • Amazing Technicolor Population: She has blue skin.
  • Antiquated Linguistics: Used to give her an ominous and mystical aura (it's more obvious in Japanese). Also see Sesquipedalian Loquaciousness below. She tends to drop it when showing vulnerability, though, like when cutely begging Kimihito to get her head back to her body after initially ordering him like an inferior being, and when Ms. Smith is intimidating her.
  • 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.
  • Blue-Skinned Space Babe: The cover of volume 7 reveals that, among the other odd parts of her appearance her skin is a pale blue color, which makes a certain amount of sense given her mythical origins. That said, she's also the most physically-human in appearance of all the girls living at Kimihito's house.
  • Broken Streak:
    • She may be a part of the 'family', but she's the first of them who doesn't show any clear romantic attraction to Kimihito. She does fancy him quite a bit, of course, but doesn't feel the need to pursue him at all, since she's fine with the fact that she'll have him forever once he dies.
    • She's the only member of the main cast who doesn't have a nickname for Kimihito, (though she's yet to address him in any way outside of pronouns).
    • She's the only girl living with Kimihito to not be shown naked (outside of some imagine spots, but she wasn't actually stripped down).
  • The Comically Serious: The expression on her face never changes even in comical moments, which can make her really funny. Her headless body is actually a lot more expressive.
  • Demoted to Extra: After her arc's over, she's pretty much a background character that pops in once in a while. This is justified in story by saying that Lala has so little presence that even her own housemates, except for Kurusu, forget she's even there. However, she does get her own chapter.
  • Friend to All Children: Has a very soft spot for kids. She just can't mingle with them very well.
  • 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 doom and gloom speeches are 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. Then again...
  • 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. She's pretending to play pretend to hide the fact that she actually does have some power over death, though it's pretty much limited to being able to talk with Kimihito when he's on the verge of entering the afterlife.
  • Headless Horseman: 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 that's nearly as large as Nyarko's. It's notably absent when she's speaking with Kimihito in the afterlife and being incredibly straightforward about her opinion of Kimihito.
  • The Immodest Orgasm: Courtesy of Rachnera and Suu on her body while Kimihito and a few of the girls are looking for her head. Kimihito is not amused at the fact that, while he's trying to hide from the police, Lala's head suddenly (and loudly) moans in pleasure.
  • I Will Wait for You: In a way, Lala's confession to Kimihito is this. She states she has no interest in chasing him like the other girls do because she knows that one day he will die. And since she is part of the underworld they can be together then.
  • Limited Wardrobe: Lala has worn four outfits throughout the series but two of those are her standard outfit without the coat, scarf, and gloves while the other one was a kimono she borrowed as a client of the Arctic Inn.
  • Losing Your Head: Although a natural thing for her, most of the time is uncalled and unwanted. During her introduction, 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.note 
    • She actually does have some supernatural abilities though, which means she may not actually be a chuuni, but is making people believe she is.
  • Mundane Utility:
  • Mystical White Hair: Her hair is white, which hints at her being a Dullahan.
  • Obfuscating Stupidity: The others dismiss her talk of being a psychopomp as delusional banter. To an extent, it's not.
  • Offscreen Teleportation: Lala has a tendency to appear and disappear off-panel. Chapter 38 reveals she can actually teleport.
    • 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.
    • When Yukio accidentally freezes Kimihito in Chapter 31, Lala is shown watching him defrost on the next page - presumably after meeting him in the afterlife - with Papi asking her how and when she arrived at the hotspring.
  • Out of Focus: Played for Laughs and lampshaded. She "has no presence" and following her arc mostly appears in the background of the house, if at that.
    • She isn't even initially taken with the group to the hot springs, as noted in Offscreen Teleportation.
    • Likewise she is ignored/missing when the group go to the hotel with Mero.
  • Psychopomp: She claims to be an incarnation of Death. While this is initially dismissed as a childish delusion, in Chapter 30 its revealed she can and does communicate with Kimihito whenever he has a near-death experience, though she doesn't actually bring him back to life.
  • Rapunzel Hair: When she has her head in its place, her hair can reach past her waist.
  • 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.
  • Reverse Psychology: Lala actively employees this tactic to trick people into believing that her status as an actual Psychopomp is just her being overly dramatic. Needless to say, but this works on absolutely everyone who hasn't regularly appeared at death's literal doorstep like Kimihito.
  • Scarf of Asskicking: Used to hold her head in place.
  • Sesquipedalian Loquaciousness: Her longwinded and convoluted formulations make it hard to understand what she wants to say. It's apparently a trait of her species.
  • 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.
  • 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 has an indent in it, and according to her profile, she doesn't really take care of it, so it lacks an edge. Of course, it works just fine as a blunt instrument...
  • Stealth Hi/Bye: Is very good at this, much to Kimihito's dismay.
  • The Stoic: Her face is occasionally covered in sweat drops when she is stressed, but her bored stare never changes. Except once, when Rachnera plays with her body.
  • Sugar and Ice Personality: Very cold and blunt, but still a sweet girl who loves Kimihito just as much as the other girls.
  • Take a Third Option: In chapter 38, she puts herself in a dilemma when she meets Yuuhi. Does she allow her to die from a terminal illness, or commit what is apparently a taboo for a Dullahan by extending her life? She eventually comes to the decision to turn the girl into a zombie with one of Zombina's teeth.
  • Together in Death:
    • The letter she sent implied this and was originally thought to just be a case of her chuuni habits.
    • However, she reveals in Chapter 30 she was being literal. In a really odd Your Soul Is Mine kind of way. As a Dullahan, once Kimihito dies, he'll be with her in the afterlife...forever. And she's content to wait until then.
  • Token Wholesome: She is the most wholesome member of the group by far. She shows the least amount of skin, has less fanservice moments than the others, and has had no nude scenes at all. The Lala-centric Chapter 38 notably had no fanservice whatsoever.
  • Walking Spoiler: Beyond entering fairly late into the story, it's impossible to explain why she likes Kimihito without revealing that she really IS an agent of Death.
  • Woman in White: In the afterlife while talking to Kimihito, she trades in her normal outfit for a simple white dress and white thigh-highs. Upon closer inspection, one can notice she's wearing the white dress normally. She's just not wearing the coat, scarf, and gloves here.
  • Your Soul Is Mine: She states that Kimihito's soul will belong to her once he dies.
  • Zettai Ryouiki: Grade-A with her boots as best seen here.


    In General
From left to right: Tionisha, Doppel, Zombina, Manako

A squad of four female monsters and Ms. Smith, who go after those monsters who exploit the Interspecies Protection Act.
  • A Lizard Named "Liz": As usual, their names are based on their species/traits, but not exact matches.
  • 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 Girl: 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".
    • The anime changes it so instead of being an acronym, it's short for "MONster's New Law"
  • Obvious Rule Patch: They more-or-less owe their existence as a law enforcement body to the shoddy and loophole-ridden state of extraspecies law making the arrest of extraspecies criminals by human cops very tricky legal ground.
  • Pretty Freeloaders: In Volume 3's extra, Kimihito and Meroune point out that they spend a lot of time at his house. And in Mero'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 in 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.


Voiced by: Rei Mochizuki

A living dead and commander of the squad.
  • Alien Blood: To prevent decomposition, her blood has been replaced with embalming fluid 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.
  • Boyish Short Hair: She has short hair and she's The Lad-ette.
  • 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.
  • Can't Act Perverted Toward a Love Interest: The first sign she's beginning to develop serious feelings for Kimihito is that she suddenly feels very embarrassed at the idea of him seeing her nude, even though she had him sew her detached breast back on as a prank when they first met.
  • 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. 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, at least, is rather solid.
  • Fiery Redhead: The anime and official merchandise give Zombina bright red hair to fit her personality.
  • Friendly Enemy: With Cici. Since they're similar races, Zombina has to deal with the trouble Cici causes, and they've ended up forming a bond over time.
  • Good Thing You Can Heal: Well... Not die from gruesome injuries anyway. She actually can't heal naturally anyway.
  • 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.
    • Her suggestion to Manako goes even further into Awesome, but Impractical territory in the official English version, suggesting the use of sawed off shotguns rather than simply modifying the sniper rifle itself.
  • Hypocritical Humor: Somewhat dislikes movies with fast, active zombies... despite being one herself. Though, Fridge Logic kicks in, as many people in Real Life don't enjoy watching movies for entertainment with characters that are too much like them.
  • Immortal Life Is Cheap: Good thing she won't die even if she's killed.
  • 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.
    • Later it makes sense with the information that she has an artificial heart and blood.
  • Made of Iron: See Deliberate Injury Gambit, Immortal Life Is Cheap, and Immune to Bullets. Zombina getting horribly injured has pretty much become a Running Gag.
  • Mark of the Supernatural: Her eyes are yellow (right) and green (left). 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.
    • It's explained on a side page that because she's dead, her skin won't repair itself when she's injured. So when her skin is broken or pierced, she puts a skin graft over the wound. This is what leads to her patchwork appearance.
  • My God, What Have I Done?: When she finds out her tooth was used to zombify Yuuhi, she's absolutely mortified, even though she doesn't even remember doing it and it was Lala who did the deed via a pair of pliers.
  • 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.
  • Our Zombies Are Different: Her kind are specifically stated to be Plague Zombies created from an infectious disease, although she doesn't appear interested in spreading it, and is horrified when she thinks she did by accident. She also has an artificial heart and blood to prevent her body from decaying. It's also revealed that there are other subspecies of zombies that don't fall under this description, such as mummies or jiang shi.
  • 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.
  • Sliding Scale of Undead Regeneration: Type II. She can't heal normally, but she doesn't rot either.
  • Stealth Pun: As stated below, she's a Yaoi Fangirl, which in Japanese can be rendered with the word "fujoshi". The literal meaning of "fujoshi" is "rotten girl", so we have a zombie girl that is metaphorically rotten inside and "literally" rotten outside.
  • 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.
  • This Is Gonna Suck: She manages a deadpan "Uh..." as a giant-sized Suu and Kii topple directly at her.
  • Tomboy: Boyish Short Hair, The Squadette, not a bit girly, Hot-Blooded. Check, check, check.
  • 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.


Voiced by: Saori Onishi

A doppelgänger who serves as the infiltrator of the squad, due to her shapeshifting abilities.
  • Aren't You Going to Ravish Me?: After her date with Kimihito, she offers to let him do whatever he wants to her in the form of whatever woman he desires. Instead, he asks her to wear clothes.
  • Black Eyes of Crazy: Averted, as she's not crazy, but she does have black sclerae in her default form.
  • Body Double: Served as one for Ms. Smith at least on one occasion.
  • Dark-Skinned Blond: In her Shapeshifter Default Form she has dark skin and white hair, as shown in her full-color pictures and the anime.
  • 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.
  • 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.
  • 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. Her profile hints that she is in fact a genuine Eldritch Abomination, mentioning she has an air of Crawling Chaos around her. Chapter 39's full-color intro implies that she can't control her appearance all the time, showing creepy red eyes and rows of teeth among her strands of hair while she's half-asleep. Chapter 40 has her turn into a vaguely-seen, indescribable something only seen in silhouette, and her true nature is further teased by her choice of reading material: a Cthulhu Mythos compilation.
  • 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.
  • Master Actor: She's quite skilled at acting like other people; this makes her quite skilled at manipulation as well.
  • Mystical White Hair: A "doppelgänger" with white hair.
  • Naked People Are Funny: Doppel is actually always naked; the clothes of her disguises come from her hair. The only time she wears clothes is at Kimihito's request, and she finds it extremely embarrassing.
  • Nice Job Breaking It, Hero:
    • Not only did her writing the original D letter 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.
    • Her attempt to spark a friendship between Miia and Draco backfired when Liz - who Draco had been flirting with immediately prior - showed up.
  • Oddly Visible Eyebrows: Perhaps one of the few examples with an explanation. As stated above, her hair will always appear conveniently placed. This includes being "behind" her eyes so as to not obscure them.
  • Oh Crap!: When the orc leader catches up to her due to Lilith's form having short legs, Doppel is noticeably afraid. She later tells Kimihito that she's not much stronger than an ordinary human.
  • Only Known by Their Nickname: "Doppel" is not her real name. She uses that name because her real name cannot be pronounced or understood by humans.
  • The Prankster: Wrote the original threatening note to try to push Kimihito out of maintaining a Balanced Harem. Chapter 40 reveals her general tendency to be helpful with her pranks, such as putting a stop to Lilith's mischief and helping Draco realize she should apologize to Miia for their disastrous first encounter. She further reveals that she loves working for MON because it allows her to prank without worrying about getting in trouble, as nobody cares if she messes with someone who is causing problems for others.
  • Prehensile Hair: She wraps herself with it to form her disguises, and as a convenient Scenery Censor. She only occasionally uses it to grab things, and in the end credits of the show, she uses it as a form of locomotion.
  • Rapunzel Hair: Her hair is about as long as she is, and then some. As stated in the Prehensile Hair entry above, she doesn't even need to walk, her hair carries her!
  • Shameless Fanservice Girl: She always goes around naked in her humanoid Shapeshifter Default Form, but she doesn't bother getting embarrassed because that's not her real form anyway. When the very end of Ch. 40 shows that she complied with Kimihito's request to put on some clothes, she doesn't seem too happy with it. In fact, she actually gets embarrassed that she has to wear clothes, to the point where she covers herself with her own hair.
  • Shapeshifter Default Form: While it's not her true form, her preferred form is a young girl with long white "tentacle-hair", jet-black skin, and Supernatural Gold Eyes with black sclera.
  • Technically Naked Shapeshifter: She is technically always naked; the clothes of her disguises come from her hair.
  • Totally Not a Werewolf: It's mentioned in her profile that despite her abilities and nickname she's not a doppelgänger.
  • Transformation Horror: When confronting the orc leader in chapter 40, Doppel extrudes tentacles and insectoid limbs before splitting her head and body open into an enormous mouth lined with fangs and phlegmings, only shown in silhouette. The orc is reduced to a drooling wreck constantly mumbling "Scary little girl scary little girl scary little girl...".
  • The Unpronounceable: It's said her real name cannot be pronounced or understood by humans.
  • Voluntary Shapeshifting: Though clothes seem to be optional. She mostly uses it to sneak into sensitive places.
  • Weak, but Skilled: She admits her actual physical strength isn't much better than an average person's, and she has to rely mostly on her transformation abilities alone, though they more than make up for it.
  • Well-Intentioned Extremist: She really enjoys playing pranks, but they typically have an intended ultimately positive outcome, such as punishing Lilith for continuing her mischievous behavior, or helping Draco apologize to and make up with Miia. Or trying to help Kimihito break out of maintaining his harem.


Voiced by: Momo Asakura

A monoeye who serves as the sniper of the squad, due to her keen vision.
  • A-Cup Angst: She is especially conscious of her flat chest. In Chapter 29, when Manako hears that Centorea's breasts are so big that they snap a 103 centimeter bra, she does not take it well.
  • 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: She has a single eye, but she's a Monoeye instead of a Cyclops. Cyclops are a sub-species of her race.
  • 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 limited 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: Due to only having one eye, she has poor depth perception when it comes to close range objects 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: Only once as a form of Offscreen Teleportation. 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.
  • Token Wholesome: Fanservice wise, she is easily the most wholesome girl in the entire manga, Lala included. She has had very few (if any) fanservice moments.
  • When She Smiles: It took her about 30 chapters, and her face was partly covered, but it happened.
  • You Gotta Have Blue Hair: She has dark purple hair, making her look kinda like an anime-fied Turanga Leela.


Voiced by: Yurika Kubo

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.
  • Cute Bruiser: Despite having enough raw strength to throw a vending machine with little visible exertion, she gives Manako a run for her money for the most conventionally feminine member of MON.
  • Dark-Skinned Blond: Usually how she's drawn, backed up by her full-color pictures and the anime.
  • Expy: Has a uncanny resemblance to Yuugi Hoshiguma.
  • 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.
  • Hair of Gold, Heart of Gold: She has blonde hair and a cheerful and feminine personality.
  • Heart Is an Awesome Power: Her warm presence is so monopolizing that Kimihito, who is no stranger to powerful monster-girls, couldn't escape it and regards it as dangerous.
  • Height Angst: She's very sensitive about her great size.
  • Horned Humanoid: Like most oni.
  • I'm Taking Her Home with Me!: She finds the dolphins at the aquarium so adorable she grabs one and tries to take it with her.
  • 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."
  • Innocent Fanservice Girl: Shows shades of this during her date(s) with Kimihito.
  • Lap Pillow: Does this to Kimihito and later does it to Kii and Polt at the same time.
  • Lethal Klutz: Supplementary material show this. While she appears in only two of the about 70 web-based shorts, she still manages to bust open part of a wall in Kimihito's house and then smash a coffee table... while apologizing for the wall no less!
  • Marshmallow Hell: Gives Kimihito this treatment in Chapter 22, and again in Chapter 41.
  • 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.
  • Our Ogres Are Hungrier: While she looks like the oni from Japan, she's actually an ogre, with the oni being a subspecies of ogre.
  • Rapunzel Hair: Her hair extends all the way down to her waist.
  • Running Gag: Her habit of picking up and throwing vending machines.
  • 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. She has tall barriers/shields that brace the roof, too, so that it doesn't collapse on top of her.



Voiced by: Teruyuki Tanzawa (leader)

A group of orcs who entered Japan illegally, taking a comic shop hostage to make ridiculous demands. They are handedly defeated by MON, making their first introduction in the series.
  • All Men Are Perverts: All of the orcs shown are men, and their demands are the printing of orc-centric pornography. Later on another orc not a part of the initial group is shown arguing with a human over the superiority of orc-centric pornography over tentacle monster-centric pornography.
  • Attempted Rape: The orcs intended to rape one of their hostages in front of the police. Sadly for them, the "hostage" turned out to be Doppel. In chapter 40 the leader makes a return and assaults Draco, but is stopped again by Doppel using what is implied to be her true form.
  • Fun with Acronyms: In the official English release, they call themselves the "Pioneer Orc Renaissance Kinsmen" or PORK for short.
  • Go Mad from the Revelation: The Orc Leader fails his sanity check after being confronted by Doppel and is left all-but comatose by the sight of her monstrous transformation.
  • Knight of Cerebus: The threat is resolved within a chapter, though they are gun toting terrorists responsible for an Out-of-Genre Experience.
  • Lolicon: The leader of the orc pack openly admits to preferring young girls when assaulting Draco, and is such a pervert that he abandons Draco to chase after the child-sized Lilith and makes it clear he intends to rape her. Lilith turns out to be Doppel in disguise, and she proceeds to Scare 'Em Straight.
  • Loophole Abuse: Using the cultural exchange laws, the orcs can perform their terrorist actions without fear of being attacked by the human police force. Eventually defied by Ms. Smith - when the orc leader tells her to accompany him in the deportation that would be his maximum legal punishment, she has Doppel provide her an alibi while she takes out her frustration on him.
  • Madness Mantra: When the orc leader sees Doppel's transformation, all he says afterwards is "little girls scary".
  • The Nose Knows: Orcs have an incredible sense of smell, they can smell anything within a kilometer radius.
  • Not-So-Harmless Villain: The orcs are idiots, yes, however their leader does mercilessly gun down a special forces agent who tried to sneak in, and attempted to rape a hostage in front of the police force.
  • Oh Crap!: The orc leader, when Ms. Smith gets ready to really punish him. He has another moment when Doppel transforms into an eldritch horror, destroying his sanity.
  • Our Orcs Are Different: They straddle the line between Tolkien and Blizzard orcs. They have human level intelligence and a high level of cunning, capable of using fire arms. Though they violently take hostages and are mostly concerned with their own lusts.
  • Pig Man: The orcs look like this.


Voiced by: Shiina Natsukawa

A kobold who runs a fitness center for extraspecies, and the first non-government monster girl to NOT be added to the harem.
  • Bizarre Alien Biology: She has four more pairs of nipples on her abdomen, beneath her fur, much like an actual dog. Her profile notes that some kobold subspecies even develop a second pair of full breasts.
  • Cool and Unusual Punishment: It's revealed that one of her side jobs is disciplining extraspecies who break the rules (like running off without their host family). Her choice of punishment is to force them to walk an entire marathon!note 
  • Cute Little Fangs: Comes with being a kobold.
  • Demoted to Extra: The anime adaptation skips her introductory chapter entirely and cuts out her contribution to Kurusu's food worries, instead giving her brief, unvoiced cameos during episodes 10 and 11.
  • Genki Girl: Polt seems to have near-infinite reserves of energy.
  • Large Ham: She likes to shout. A lot.
  • Large Ham Announcer: During the race.
  • Living Lie Detector: A side effect of her potent sense of smell, she can pick up pheromones when someone is stressed or exhausted. And as Draco and Lilith found out, she can tell when they're just acting tired to try to get out of walking a marathon.
  • 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.
  • No Indoor Voice: It's rare to hear her not yelling at the top of her lungs.
  • Non-Idle Rich: She (and kobolds in general) are financially well off due to her species' association with mining cobalt. She owns and manages both the Sports Club Kobold and Kobold Stadium, as well as a number of spas, massage parlors, and relaxation centers.
  • Perpetual Smiler: The only time she isn't smiling is when she's surprised.
  • Petting Zoo People: Though she initially appears to just be a Little Bit Beastly, her character profile reveals that she's actually completely covered in fur, head to toe. It just grows thicker on her head, wrists and ankles.
  • 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 they will be fixed when the place opens to the public.
  • Skinship Grope: Does this to Kii in an effort to "extract water from plants" after Kii drank all the water that Polt had prepared for herself, Draco, and Lilith.
  • Spell My Name with an "S": Volume 4 of the English release originally had her name as "Port".
  • Token Wholesome: She's up there with Lala and Manako on this. Outside of the Male Gaze entry described above (and an image of her naked and covering her breasts in an omake), she's one of the very few female characters that hasn't had any fanservice moments. When Kii tries bondage on her in chapter 41 it is less graphic than with other girls and Polt mistakes it for a new type of sports training. Even when shown naked in the same chapter, it's from a distance where nothing is seen and is mostly a background detail.


Voiced by: Airi Ootsu

A dragonewt with a creepy crush on Miia.
  • A-Cup Angst: Her profile reveals that most dragonewts have large breasts, something Draco is clearly lacking. She's shown with an embarrassed look on her face as she tries to claim that she's not small, everyone else is too big.
  • Adaptational Badass: Kind of. Unlike in the Manga, she does have the ability to fly in the anime...for all the good it does her: Mon shoots her escape attempt down with ease judging by the holes in her wings, and one blast of Suu's poisoned spray ends their fight before it even starts.
  • Awesome, but Impractical: As stated below, Draco's got a bad case of this. She's got scales that can block bullets! But her clothing usually catches on them, and she doesn't run into gun-wielding maniacs too often. She's got an extremely muscular tail! But she can't sleep on her back and she needs specialized clothing. She's got wings! But they're not strong enough for her to do more than glide, she has to deal with a lot of air resistance when trying to run and again, they get in the way.
  • Bifauxnen: To the point that everyone thinks Draco is a man at first. Downplayed after the truth comes out: her appearance in Chapter 25 is far more clearly feminine.
  • Blondes Are Evil: The anime colors show she's blonde.
  • Butch Lesbian: She's quite obsessed with Miia and she's so masculine that everyone mistook her for a man. In chapter 40, she also tries to hit on the lizardwoman Liz, only to be promptly shut down.
  • Butt Monkey:
  • Does Not Like Men: She outright states she hates men.
  • Draconic Humanoid: Draco has dragon wings and a tail.
  • Fantastic Arousal: As Suu discovers, the tip of her tail is sensitive just like Miia's.
  • Fantastic Racism: Initially appears to have a case of this, though it's eventually revealed she doesn't like men rather than humans in general. In fact, in one omake she's shown requesting to have a cute girl as her host, suggesting she has no problems with humans, provided they're female.
  • Foreshadowing:
    • Well before The Reveal, Draco orders Miia to stop talking about men, not humans, foreshadowing her Psycho Lesbian status.
    • There's also one on the chapter's cover page which reveals Draco's species' name and family's coat of arms.
  • I Just Want to Have Friends: Although she has a pretty strange way of showing it. She seems to be getting better however, as she's trying to just normally visit Miia at the house by Chapter 34. Unfortunately, no one was home at the time. She seems to horn in on any reptilian extraspecies in general: she starts hitting on Liz as soon as she learns that she's a lizardman.
  • Knight of Cerebus: Remember how Rachnera could have been the manga's first villain? Well, she missed out on that, and Draco got the title instead. She was very close to forcing herself on Miia, and would have had her way if not for Kimihito and Mero being Big Damn Heroes.
  • No Social Skills: When Draco actually tries to be civil, it's apparent that her social skills are very lacking. She has a hard time apologizing not because she doesn't want to, but because she doesn't know how to apologize.
  • Our Dragons Are Different: This dragon is a Winged Humanoid with draconic wings and a tail.
  • Purple Eyes: In the anime at least.
  • Psycho Lesbian: She tries to force herself onto Miia. A bonus omake with her and the other side girls indicates she actually doesn't like being called a lesbian, though the official English Translation clarifies that she was actually indignant about Lilith's foul mouth, and suggestion she suck on Kii's breasts in public.
  • Red Herring: While the initial assumption was probably the same as Miia's, Draco is NOT the one who sent Kimihito the death threat. She doesn't know anything about it and even if she did she is only interested in Miia.
  • Slasher Smile: She's probably sporting the scariest one thus far in the series. And that's including Rachnera's Nightmare Face.
  • Smug Snake: Draco certainly believes in draconic superiority. Though it turns out that being a dragonewt is nowhere near as great as it sounds. See Awesome, but Impractical and Butt Monkey above.
  • Spell My Name with an "S": The scanlations use Draco, the official English release uses Drago.
  • Stalker with a Crush: Draco is introduced stalking Miia from the shadows.
  • Take That: Draco is less than pleased when Miia can't stop being infatuated over Darling despite the fact that Miia felt left out at the aquarium.
    Draco: What's so great about that human anyway...? He's acting like the idiot main character in some harem-style light novel!
  • Tomboyish Name: "Draco" is typically masculine. Then again, so is this Draco.
  • Villain Decay: In her first appearance she almost has her way with Miia and would have succeded if not for Kimihito and Mero. In her next appearance she appears out of nowhere and attempts to attack Kimihito...and is promptly molested by Suu and dealt with. And then in a bonus omake she's being forced to walk an entire marathon (42 kilometers!) by Polt as punishment for going out without her host family. When she's shown up after that, she hasn't even been trying to do anything villainous.
  • Why Did It Have to Be Snakes?: She's creeped out by fish, of all things, as seen in Chapter 25.
  • Winged Humanoid: Draco's wings are the bat-like ones usually seen on dragons.
  • Wings Do Nothing: Her wings are only capable of gliding at best, and their shape and size cause wind resistance that slows down her running. The anime shows she can lift off the ground and glide, but she still can't actually fly.
  • Your Size May Vary: Her wings can vary in size sometimes, most notably in her debut where they look like they're big enough to enable flight.


Voiced by: Asami Seto

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.
  • Adaptational Modesty: The anime adaptation gives her bark covering for her crotch.
  • Alien Hair: Her hair is made of leaves.
  • 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.
  • 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: Originally 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, and supplimentary materials have since revealed that her apparent age is heavily tied to her nutritional intake: she looks older when she's healthier and younger when she's starving.
  • 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, Kii can assume a more... adult-looking form when well-fed.
  • 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.


Voiced by: Atsumi Tanezaki

A mischievous devil who decides to cause some trouble to Kimihito and Centorea's date for her own amusement.
  • Ambiguously Brown: In the anime.
  • Attempted Rape: When her hypnotism fails to cause Kimihito to assasult her, Lilith tries to force herself on him. Fortunately, she is stopped by Doppel.
  • Black Eyes of Crazy: Like Doppel she has black sclera, but she seems more mischievous than malicious or insane.
  • Blackmail: Her scheme in Chapter 40 is to hypnotize Kimihito to trick Rachnera into thinking that "Honey" got infatuated with her, thus making her leave Kimihito's house and try to get together with her when she goes all alone in the world. Kimihito and Doppel quickly put a stop to that.
  • Breaking Speech: Tries this on Rachnera by pointing out how she is insecure and fearful about humans accepting her and hides in the shadows to avoid being seen. See below for the response.
  • Bullying a Dragon: She spent most of the chapter she first appeared in being a Troll to Centorea and Manako by playing on their insecurities. She then tries the same with Rachnera... and that's the last we see of here before Rachnera reduces her to a sub.
  • Casual Kink: Really enjoys bondage and refers to Rachnera as "Mistress".
  • Does Not Like Men: She believes that all men are lolicons.
  • Evil Laugh: Written in English as "Ki hi hi!"
  • Fille Fatale: In Chapter 40 she tries to seduce Kimihito in order to get dirty pictures to show to Rachnee, enabling her to get her "Mistress" all to herself.
  • 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.
  • Karma Houdini: Chapter 40 shows that she hasn't changed her ways, and again she gets saved from serious troubles only to disappear and get away scot-free from what she'd done. The only time she was properly punished, she turned out to be Too Kinky to Torture.
  • 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 She Looks: Like Papi she is an adult but has the body of a small child. Her profile notes that she enjoys abusing this in petty ways to get into movie theaters and buses while paying only child prices. This backfires on her big time when she tries picking a fight with Rachnera, who notes that she's an adult in a childlike body and therefore can be "punished" as an adult.
    • The anime end-card for Episode 12 reveals that this is because she belongs to the Lesser Devil subspecies, who are noted to look like children.
  • 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, though she does gain a motive later on in trying to get back with Rachnera.
  • 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.
  • Psycho Lesbian: She greatly enjoys being tied up and "tortured" by Rachnera to the point where she was begging to be "rewarded". In Chapter 34, she's seen deliberately looking for Rachnera and is upset that they haven't met up again since their last "encounter".
  • 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 (although played with in that said bondage turned her into Rachnera's quivering sub).
  • 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.
    • In Chapter 40 she and Kimihito finally get face-to-face (and face to... other body parts). He's immune to her suggestive poses, and when she tries hypnotizing him, he ends up acting exactly the same way he already was.
  • Villain Decay: Happens to her even faster than it did Draco. Between Rachnera turning her into a quivering sub and Polt punishing her for going out without her host family, whatever threat she once posed is long gone.
  • What Happened to the Mouse?:
    • She's apparently been forgotten about/disappeared after Chapter 21 as she wasn't seen inside the attic in newer chapters. This is averted by the bonus material in volume 5 revealing she was released by Rachnera and subsequently punished for going out without permission/unaccompanied by having to run a marathon.
    • She shows up again in the main story in Chapter 34, distressed at the thought Rachnera might have abandoned her.
    • Part of Chapter 40 is dedicated to her. She's still as mischievous and infatuated with Rachnera as ever.
  • Winged Humanoid: Has small bat-like wings.
  • Wings Do Nothing: She can't fly with her wings, hence why she ran away from the wild boar instead of flying.
  • You Gotta Have Blue Hair: She has light turquoise hair.
  • Zettai Ryouiki: Class B thanks to her jacket.

    Miia's mom

Miia's mother, who claims to come only to visit, but intends to pursue her own agenda regarding Kimihito.

    Papi's mom

Papi's mother, who shows up to retrieve her while trying to remind her daughter of something.
  • Dark-Skinned Blond: The result of a dark tan, hair bleach and heavy makeup.
  • Do You Want to Copulate?: Asks the bicycle cop if he wants to mate with her with a straight face.
  • Dynamic Entry: Like Papi, her mom makes her first appearance landing on the safety rail on Kimihito's roof. Unlike Papi though, Papi's mom crushes the railing under her talons from the force of impact.
  • Happily Married: Though harpies theoretically don't stay with the same guy, she is married to Papi's father, who is the one that influenced her to tanning and dyeing. Apparently the same free-spirited nature that created the tradition of loving and leaving men ensures that harpies who do find a guy they like just happily ignore it.
  • Harping on About Harpies: Naturally.
  • The Illegible: Her handwriting is basically unreadable. Justified in that, like Papi, the digits on her wings aren't nearly as dexterous as human hands and fingers.
  • Inexplicably Identical Individuals: As revealed in an omake, harpies (or at least the members of her and Papi's flock) all have the same natural appearance. She even blithely admits that she's not even sure that Papi is her actual daughter.
  • Mum Looks Like A Sister: As if Papi herself didn't look young enough.
  • Older Than She Looks: Bicycle Cop mistook her for another exchange student.
  • Perpetual Molt: Like her daughter.
  • Rapunzel Hair: Goes all the way down to her waist.
  • Subcultures In Japan: While she isn't a direct member, her look is clearly influenced by the "gyaru" or "ganguro" movements. Guess her husband has a thing for that.
  • Unnamed Parent: Lampshaded, as Papi can't remember the names of her parents or Kimihito.
  • Winged Humanoid: She is a harpy after all...
  • You No Take Candle: Her skill at speaking Japanese is... rather lacking, and is the main cause for the chapter's misunderstanding. She didn't want Papi to go back to a husband she didn't remember, but rather wanted to get back the photo of herself and her husband that she'd accidentally mailed alongside her letter to Papi.

    Centorea's mom

Cerea's mother, who shows up to see how her daughter is doing in fulfilling one of their "traditions."
  • Antiquated Linguistics: More prominent than her daughter's, which is reflected in the fan translation.
    Mom: Hark! Be there no one in this abode?! If thou refuse to open, state thy intention forthwith, insolent curs!
  • Expy: From the torso up, she looks like an extremely busty Karin de la Valliere.
  • Fashionable Asymmetry: She keeps one bang longer than the other.
  • Gag Boobs: Even bigger than her daughter's.
  • Interspecies Romance: She grew up with a young human boy her family wanted to use as a "teaser." He turns out to be Centorea's father, since the two of them knocked out and tricked the centaur stallion who was going to breed with her so that they could be together.
  • Letting Her Hair Down: After her jousting match with Centorea, she lets her hair down, and becomes far less strict.
  • Like Mother, Like Daughter: Unlike the other mother/daughter relationships introduced so far, Centorea clearly didn't fall far from the tree. Her mom seems to be a snapshot of the sort of person she'll be in a few years.
  • Mum Looks Like A Sister: Once again, will we ever see an older-looking monster girl?
  • Our Centaurs Are Different: Apparently they have some weird mating traditions, reflecting real-world racehorse breeding practices. For one, generations of eugenics have resulted in dim-witted males that look like muscular barbarians with a side of Gonk and matching personalities, so they use various "teasers" the girls find more attractive to get them all riled up before mating. Understandably, most modern centaur girls aren't terribly thrilled by this, including Centorea and her mom.
  • Prim and Proper Bun: She keeps her hair in a bun, to reflect her strict nature.
  • Proud Warrior Race Girl: She calls out Cerea for not following their traditions. Actually more sympathetic than it seems at first blush. She turns out to be using a clever plan to subvert those same traditions and bring about progressive change.
  • Red Baron: She's known as the "Goddess of Jousting".
  • Unnamed Parent: Pretty much a Running Gag at this point.


A yuki-onna running an onsen resort.
  • Acquired Poison Immunity: Is using slow, constant exposure to the springs she works in as a method of training her body to better withstand her natural weakness to heated temperatures.
  • Crazy-Prepared: She is really thorough when it comes to designing her resort, having accommodations for practically every monster girl imaginable.
  • Early-Bird Cameo: First appeared in a 4koma on Okayado's twitter.
  • Emotional Powers: She loses control of her ice powers when she loses her stoic expression.
  • Frozen Face: She's trying to learn how to smile for the customers, but she has a hard time at it.
  • Hair Decorations: Her hair is done up using a hairclip created from her own ice, resembling a snowflake that changes everyday due to her cold aura.
  • An Ice Person: As befitting a yuki-onna, though she has many difficulties running a hot-springs resort because of her powers.
  • Impossibly-Low Neckline: She wears her kimono somewhat loose, leaving an off-the-shoulder neckline. Though it works since she has an obi sash to hold the dress.
  • Interspecies Romance: Surprising no one, she's dating the human future heir of the resort.
  • Kryptonite-Proof Suit: Wears a special suit to maintain the springs despite their heat.
  • A Lizard Named "Liz": A yuki-onna named Yukio.
  • Personality Powers: Subverted. She isn't really "cold" so much as she just has difficulty expressing herself.
  • Rapunzel Hair: Her hair reaches down to her knees.
  • Single Woman Seeks Good Man: She is completely in love with her boyfriend because he's kind, considerate and has a cheerful smile.
  • Statuesque Stunner: Her boyfriend finds her tallness attractive.
  • The Stoic: It's a problem she's had to work on, since her cold demeanor is scaring off customers.
  • Sugar and Ice Personality: Though she's usually quite controlled, she melts when thinking about her boyfriend or when embarrassed by displays of emotion.
  • Symbol Motif Clothing: As befitting of a yuki-onna, Yukio wears a kimono adorned with snowflakes.
  • When She Smiles: When talking about her beloved young master, she unconsciously smiles which Kimihito notes. However, this causes Yukio to lose control of her composure and nearly freeze Kimihito.
  • Youkai: Yukio is a yuki-onna, a Japanese ice monster.

    Luz Ninetei

A nine-tailed fox in the exchange program, working at a shrine as a miko.


A minotaur working on a farm.
  • Amazonian Beauty: Strong enough to hoist logs over her shoulder, the tallest character in the series thus far (that isn't in Kaiju-mode anyway), and drop-dead gorgeous. She's officially stated to be 231cmnote  tall in her profile.
  • Boobs of Steel: Her breast size is easily larger than Centorea's (I03 cm or an I Cup).
    • Confirmed in her official profile (shared with Merino, Tawn & Cott). She's a 171 Q. Cathyl is both taller and bustier than Tionishia!
  • Does Not Like Shoes: Since her feet are hooves.
  • Facial Markings: She has black splotches beneath her eyes, looking almost like a permanent Blush Sticker.
  • Fantastic Arousal: Being milked is very arousing, even orgasmic, for her; so she normally has her boyfriend do it as it would be too awkward to ask a friend. When she believes her boyfriend is cheating she opts for a stranger (Kimihito), since she won't likely have to face him again and she only wants it done to relieve the pain she is in from the milk building up, not for pleasure.
  • Foreshadowing: The remark that she isn't good at remembering names ends up being this, as it led to a misunderstanding with her boyfriend.
  • Gag Boobs: The largest in the series so far (even bigger than Centorea's), barring giant transformations. This is to be expected, since she is apparently part-cow. They get a bit smaller once she has been milked.
  • Hey, You!: Because she's bad with names, according to her. This leads to her thinking her boyfriend is cheating on her, because he was calling the names of the sheep on the farm, which she forgot.
  • Horned Humanoid: Typical of a minotaur.
  • Interspecies Romance: She's in a relationship with her human host, the owner of the farm where she works.
  • A Load of Bull: She's a minotaur.
  • Meaningful Name: Kyatoru/Cathyl is a mispronunciation of cattle, as in livestock, such as dairy cows. Not exactly a flattering meaning, but a meaning nonetheless.
  • Multicolored Hair: White in front, black in the back.
  • Muscles Are Meaningless: Averted. She's shown to be very strong, and while not exactly ripped her arms do show well-developed muscles.
  • Oral Fixation: She's always seen with a blade of grass hanging out of her mouth.
  • Spell My Name with an "S": Is it Kyatoru or Cathyl? There's even some translations going with Cattleya.
  • Statuesque Stunner: Taller than even Tionishia, barely.
  • Tomboy and Girly Girl: The Tomboy to Merino's Girly Girl.
  • Your Cheating Heart: She believes her boyfriend is cheating on her. Turns out, he's not and she had nothing to worry about.


A satyr working on a farm.
  • Animal Eyes: She has rectangular pupils, like a sheep.
  • Fantastic Arousal: Having her fleece sheared gets her excited, to say the least.
  • Fauns and Satyrs: She calls herself a satyr, but she's more sheep than goat. A more accurate translation clarified her as a "pan faun."
  • Horned Humanoid: She has sheep horns.
  • Love at First Sight: She is quite taken with the new farm worker, to say the least, when he compliments her. An omake reveals she gets him to shear her (intimate parts as well) not long after.
  • Meaningful Name: Merino is a breed of sheep.
  • Nice Girl: Unfailingly kind and polite to Kimihito, Cerea, and Papi during their visit.
  • Petting Zoo People: Fauns grow fleece just about everywhere besides their faces and need to have it sheared on a regular basis. Once they've been sheared, they're more akin to being a Little Bit Beastly, as they only have a little fleece left on their legs and around their neck.
  • Tomboy and Girly Girl: The Girly Girl to Cathyl's Tomboy.
  • Vapor Wear: She isn't wearing anything under her overalls besides her own fleece.

    Cott & Ton

A pair of Barometz twins working on a farm.
  • Dark-Skinned Blond: They certainly appear to be.
  • Eyes Always Shut: Even in their profile with Cathyl and Merino.
  • Fauns and Satyrs: They aren't, they just resemble pan fauns.
  • Identical Twin ID Tag: They comb their hair over a different eye and their horns are curved in different directions. It's still not clear which of them is which; though their profile seems to imply Cott is the one with her horns pointing upwards, while Ton is the one with the downwards-pointing horns.
  • Horned Humanoid: They have cute little goat horns.
  • Plant Person: Despite their resemblance to pan fauns, they are similar to dryads. Their "wool" is also actually cotton.
  • Punny Name: Cott-Ton.
  • Single-Minded Twins: They seem quite coordinated.


A bodyguard working for the Talio Private Security Company to deal with extraspecies threats.
  • Ambiguously Gay / Ambiguously Bi: She seemed quite receptive towards Draco after being given flowers and a teddy bear by her (or rather, by someone she thought was Draco). Too bad Draco was hitting on Miia at the time. Hilarity ensues.
  • Animal Eyes: She has slitted pupils.
  • Consummate Professional: Liz takes her job as a bodyguard very seriously, and does not react well to interferences.
  • Cute Little Fangs: Most noticable when she's shouting.
  • Dangerous Forbidden Technique: Since lizards store nutrients in their tail, she risks dying of malnutrition if she cuts her tail off. Kimihito stops her from doing that upon hearing this.
  • Death Glare: When Draco hits on her, Liz intimidates the dragonewt with a menacing glare, bared fangs, and Hellish Pupils.
  • The Ditz: She berates Kinu for being stupid, but she's not much better off herself.
  • Drives Like Crazy: She keeps forgetting one of the most basic rules of driving: keep your eyes on the road.
  • It Only Works Once: Stated word-for-word in her profile about her tail-detachment comment.
  • Lizard Folk: She's a lizardman. Draco initially mistakes her for a dragonewt.
  • A Lizard Named "Liz": Literally.
  • One Steve Limit: The scanlators had initially intended to use Liz as the name for the kitsune in chapter 32. However, after the reveal of this Liz in chapter 34, it was quickly changed to Luz.
  • When All You Have Is a Hammer: You're being chased? Clearly the best thing to do is to cut off your tail and run.


A bodyguard oni working for the Talio Private Security Company to deal with extraspecies threats.

    Sebastian & Potemkin

A pair of fishmen looking to secure the safe return of a certain VIP.
  • Aerith and Bob: Sebastian is quite the common name, but Potemkin? Not so much.
  • Asshole Victim: They may not be malicious, but the problems caused by their selfishness and pettiness means it's unlikely the reader will feel anything but satisfaction when Oct and Rachnera strangle them as a threat and they get their fins chewed on by piranhas.
  • Batman Can Breathe in Space: Both are literal fish out of water. If they're anything like Mero, they too can likely breathe on land so long as their gills are damp.
  • Bitch in Sheep's Clothing: While they initially seem like faithful servants to Mero, it's later shown that they're quite selfish.
    • Whenever something goes wrong, their first concern is what will happen to them, even if someone's life could be in danger.
    • Instead of contacting the authorities to rescue Mero from Oct, they have Kimihito and the girls save her instead because they fear they'll lose their jobs if people find out they knew where Oct was because they tried to ask her for a favor.
  • Dirty Cowards: Rather than accompany Kimihito and the others on their rescue mission, they instead drop them off on the island and drive their boat away.
  • Fish People: They look like fish with arms and legs attached (they even still have a tail!). In other words, reverse mermen. They know where Oct lives, because they wanted her to turn them into handsome mermen instead.
  • Lost in Translation: Their Japanese names are actually puns on the fish-species they resemble. The English version calls them Sebastian and Flounder instead.
  • No Cartoon Fish: Look at the picture.
  • Poor Communication Kills: Semi-justified. They send a bunch of untrained amateurs after Oct instead of MON commandos because they don't want to lose their jobs on account of once trying to bargain with her. Not telling them about the giant sea anemones that live in the cave though... that's just them being lax.
  • Shout-Out: Of Sebastian and Potemkin. The English dub changes Potemkin's name to Flounder, another reference to The Little Mermaid.
  • Those Two Guys: "Those Two Fishes" is a much more accurate description, but it gets the job done.

    Mero's Mom

Mero's mother. Beware of spoilers.
  • The Caligula: She's very much unsuited to be in any position of authority, much less the queen of a nation.
  • Disappointed In You: The queen is extremely disappointed that Mero has been "tainted" by happiness in the human world and "lost sight of tragedy".
  • Dull Eyes of Unhappiness: When she's first shown, and whenever there's focus on her eyes. This stops when things go beyond her control.
  • Evil Matriarch: She has a very strong idea of what she thinks Mero should be, and doesn't particularly care whether or not it makes Mero happy.
  • Heel Realization: When it seems that Mero is actually going to die as a result of her schemes, she panics. It's implied that coming so close to actually experiencing a tragedy led her to the same realization Mero had figured out.
  • Hidden Agenda Villain: She lied about the severity of the eloping problem and started the rumors about Oct in order to dispute the Inter-Species Exchange Act, purely for the sake of creating tragedy.
  • The High Queen: The queen of a mermaid kingdom.
  • Hopeless with Tech: Her total incompetence with a smart phone very nearly gets Kimihito and Mero killed because she can't figure out how to disable all her death traps.
  • Karma Houdini: Despite being seemingly ready to murder Kimihito in cold blood, almost getting her own daughter killed, and causing a serious political issue, all she has to do is publicly tell the truth about Oct and the Inter-Species Act to her people and faces no real punishment. She doesn't quite qualify for Easily Forgiven because she keeps her true role in the arc a secret from the public.
    • That last part might have been justified; as Rachnera said afterward, the merpeople might have revolted against her if the Queen revealed she was behind everything. Revolutions can be very, very bloody, as French history has shown.
  • Mum Looks Like A Sister: Like every other mother introduced she too looks rather young for her age, though it's not as extreme as Miia or Papi's mothers.
  • My God, What Have I Done?: Realizing that Meroune is willing to risk death for the chance of a happy ending seems to break through to her.
  • Nightmare Fetishist: Much like her daughter. The queen however, is much less comedic about it, to the point of instigating a political schism for the sake of separating couples and nearly killing Kimihito just to create tragedy.
  • Ojou Ringlets: Practically Up to Eleven.
  • Sadistic Choice: She forces one on Mero. Either let Kimihito drown, or save him and be forced to come back to the Mermaid Kingdom and never see him again. It's unlikely she actually intended to go through with murder, but that's when her control over the situation breaks down.
  • Unnamed Parent: Although her last name might be inferred from her daughter.
  • Walking Spoiler: Good luck trying to say anything about her without revealing her motives.
  • Your Cheating Heart: She mentions that her husband, Mero's father, eloped with a human woman. She conveniently leaves out that she had been seeing a human boyfriend behind his back for quite a while beforehand. Kimihito muses that may have been the reason her husband left her in the first place.


A scylla, described as a villain and deceiver of mermaids by Sebastian.
  • Alien Hair: She has tentacles instead of hair.
  • Animal Eyes: She has octopus pupils.
  • Astonishingly Appropriate Appearance: Her hood looks like an octopus head, and the buckles around her collar look like octopus eyes. Combined with her tentacles, they give her the appearance of a giant octopus, especially when shown as a silhouette.
  • Breaking the Fourth Wall: Or even the fifth. In one omake she lends one of her skimpy bikinis to Manako, who is enormously flustered. Oct then asks her why she's embarassed, since she appears naked in every episode of the anime during the ending sequence! For that matter, Manako says that the anime producers didn't ask her permission to put these images in the ending...
  • Carnivore Confusion: She cooks takoyaki, octopus dumplings, in her shop. Then again, octopi are notable for eating members of their own species anyway.
  • Dark-Skinned Blond: Her hair-tentacles are noticeably lighter than her skin.
  • Expy: A half-octopus being described as a 'villain' and 'deceiver'? She's like a thinner, prettier Ursula. It fits quite well, considering Mero's obsession with the fairy tale. Ultimately subverted as she's a perfectly friendly woman with no magical powers at all.
  • Fantastic Racism: She's been accosted by countless mermaids and mermen seeking magical assistance, had malicious rumors spread about her when she was unable to help, and then made a scapegoat for the Mermaid queen's plot purely because she's a scylla.
  • Friendly Rivalry: With Rachnera. They hit it off after using their various means of constriction to duel.
  • In the Hood: She wears a hood that resembles an octopus's head.
  • Kansai Regional Accent: Maybe to make her sound more funny or sympathetic.
  • Let's Get Dangerous: Inverted. She initially presents herself as a serious threat when her pet anemones very quickly incapacitate Cerea and Miia, and she essentially fights Rachnera to a draw, all while holding Kimihito hostage and threatening to rape him if Rachnera stops fighting to go look for Mero. She later displays a much more laid-back and goofy personality once it's cleared up that Kimihito and company are merely worried about their friend, not assassins sent by the mermaid kingdom.
  • A Lizard Named "Liz": Oct, from octopus.
  • Loveable Sex Maniac: Had her tentacles down Kimihito's pants literally seconds after meeting him. This was mainly done to get Rachnera to let down her guard, but her subsequent fondling of Kimihito and offer of a "reward" was certainly genuine.
  • Not Evil, Just Misunderstood: She's not the evil witch we're initially lead to believe she is. She's actually a nice person and she can't even use magic; she was merely framed through rumors by the queen. Her "kidnapping" of Mero was also a big misunderstanding.
  • Red Herring: She's set up as a serious villain and the source of many problems in the mermaid kingdom, but she's an innocent scapegoat for a larger scheme by Mero's mother.
  • The Scapegoat: She has been framed as an evil witch who deceives mermaids as part of a scheme by the queen.
  • Solitary Sorceress: People seeking magical solutions to their, often trivial, problems have forced her to isolate herself. Mostly because she can't do any magic to begin with.
  • Unscaled Merfolk: Unlike Mero, Oct is a scylla; in place of a fish tail, she has octopus tentacles.


A jiangshi looking for a Japanese man to marry.
