Affectionate Nickname: Miia calls Kimihito "Darling", Papi calls him "Husband" ("Boss" in the English manga), Centorea and Suu call him "Master", Meron calls him "Sir" ("Beloved" in the English manga), Rachnera calls him "Honey", Tionishia calls him "Sweetie", Zombina calls him "Babe", and Manako calls him "Dear." Ms. Smith calls him "Darling" too because she finds it amusing.
Always Save the Girl: He actually racks up a pretty surprising number of crimes all to protect the girls from random people, the government, and themselves. Assault, lying to the police, harboring an illegal alien, stealing a truck, etc. He gets away with it because for the most part Ms. Smith just doesn't care.
In chapter 15, he actually thinks that this has finally caught up with him, assuming that the police are after him for attacking the director, not even considering that it might actually be Rachnera they were after.
A Man Is Not a Virgin: Averted. The night the girls are all driven crazy with lust, he has a minor Freak Out saying he's "not ready and still a virgin" showing nervousness at the prospect of his first time.
He tries to insist this is actually the case when Rachnera teases him about the possibility that he's a virgin. It's blatantly obvious that he's lying.
Badass Normal: He quite often goes out of his way to assist and protect the girls in dealing with far less pleasant humans in incredibly impressive ways, often with a Megaton Punch.
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.
"I haven't seen this in a while. Since chapter 4, I think?"
Brick Joke: His mention of having a leg fetish from an extra gets brought back up again in chapter 15. Rachnera assumes that her spider half disgusts him, and that he was only turned on from her human-like parts. He insists that she's wrong, that her legs are actually very charming, followed by "leg man" showing up by him in sparkles.
Celibate Hero: He is explicitly forbidden by law from starting a relationship with any of the girls living in his house, and with very little exception it's the girls who push to start one. Even during the initial "marriage" subplot, his first impulse was to turn Ms. Smith down rather than take advantage.
That being said, he seems to find all the girls quite attractive, and would have willingly consummated things with Miia some time ago had circumstances not intervened. Yes, they come onto him, but he has a tough time really being against it.
Chivalrous Pervert: Soundly averted. While he doesn't really object to the bizarre sexualized goings-on in his house, he also doesn't really react to them with perverted glee.
Crazy-Prepared: When Suu is on her water-absorbing (and orgasm-inducing) rampage in chapter 10 she leaps at Meron. Kimihito immediately produces a large plastic garbage bag to catch her mid-flight and contain her.
"I really am used to this..."
Crouching Moron, Hidden Badass: Chapter 14 marks the second time he's laid out a grown man with one punch, both brought on by the recipient of said punch antagonizing one of the girls in some way.
Dude, Where's My Reward?: He just barely manages to save Suu's life and Papi calls out to him, flying in like she's going to hug him, and goes right past him to hug Suu.
Made even meaner by the fact that he managed to hijack the nearby racist pair's truck, get it off the bridge, and into the river below to catch Suu, in a matter of seconds.
Fee Fi Faux Pas: He tries very hard to avoid this. An extra in Volume 3 has him worrying about what kinds of food he can bring into the house anymore, assuming he has to stop buying chicken, chicken stock, fish, fish broth, and canned tuna due to Papi and Meron. Meron's fine with fish, as seaweed alone is not a good diet and compares fish for Mermaids to cows and pigs for Humans, and Papi is "totally okay with cannibalism".
Got Volunteered: Ms. Smith pretty much just dumps "problem cases" at his house. Of the girls he deals with, only Miia and Meron are actually "normal" homestays (for a given definition of the word, given the former's repeated attempts to break the rules to sleep with him and the latter's special needs due to her biology). All of the others are either chronic runaways (Papi, Lala), have past histories of violence (Centaurea, Rachnera) or just in an extremely legally problematic situation (Suu) that are left with him because of his proven ability to keep house with even difficult personalities.
Imagine Spot: Kimihito has one where he almost consummates his relationship with Miia, only for a SWAT team to break into his house and point guns at him. The next chapter, when they end up in a love hotel, it actually happens. And during the girls' full moon driven heat he gets one that shows what would happen if he broke down and let the girls have their way with him when they are unable to control their strength. It ain't pretty. He also recognizes Lala's overactive imagination because it was something he used to do himself when he was young.
Imagine Spotting: Kimihito can apparently see and makes remarks on Miia's fantasies about him.
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.
Mistaken for Racist: Because she's running off of what she heard from the director, including the false belief that he had smashed Papi's egg into the director's face rather than a chicken egg, Rachnera assumes that he's just pretending to be a decent person but actually discriminates against extraspecies.
The assumption is made once again by Manako, as most people are apparently never willing to directly look at her out of annoyance or fear. When he's able to look her directly in the eye she begins to panic in embarrassment.
Nice Guy: The driving force behind each of the girls falling in love with him, and the reason Ms. Smith keeps leaving "difficult" homestays at his house: Kimihito can get along with anyone.
Only Sane Man: As is standard with a harem-genre protagonist. Doesn't help that the only authority figure we've seen so far is little better than his harem.
Real Men Wear Pink: He enjoys cooking, cleaning, and sewing. His skills are useful when the monster girls get clothes that need adjusting.
Rescue Romance: So far he has, at least once, ended up rescuing or protecting each member of his harem. Each time either being what caused them to fall for him or, in the event that they already had, to display their affection much more openly.
Supreme Chef: He's described as a very good chef by Smith in chapter 17, though we don't get to see any of the things he makes until chaper 25.
Kimihito takes an attack from a fake sword meant for Centorea.
He also takes three tranquilizer bullets in chapter 5, when he jumps in front of the girls.
Tempting Fate: In Chapter 24 he says several things in rapid succession that get called Death Flags in order to disprove Lala's claims.
Kimihito: "You guys are way too gullible!... In the first place that girl's not even... hmmm... Miia If, IF I make it back alive, we're getting married! I'm not sticking around here! I'm going home! I'm not afraid of anything anymore!"
Screw Destiny: Immediately after this he walks out into traffic, and nothing hits him.
Kimihito: "Got it? There's no such thing as fate! And seriously, I'm on the brink of death every single day!"
Unfazed Everyman: With a few exceptions, he is a largely open-minded and tolerant individual who takes the many bizarre things that happen to him more-or-less in stride. Most of the girls find this very attractive, even when they don't live with him or fall for him.
Even being hooked around the neck with a scythe merely registers to him as "something was off", and he casually turns around to find out what it was about.
Unwilling Suspension: Rachnera does this to him twice. Once while he was unconscious, letting him down when he mentions the blood flowing into his head, and again shortly after, rigging the webbing so that if he spit out her webbing he'd fall.
Your Days Are Numbered: Lala arrived to inform him that he's currently on the brink of death. He's fully aware of it, as he's on the brink of death daily. He's also aware it's just an act, and that she's not really a grim reaper, just a silly dullahan with a wild imagination.
Kimihito's cultural exchange coordinator. Rather lazy when it comes to her job, yet she still seems to have no problem dumping girls off on Kimihito and using him as a guinea pig for amendments to the exchange program's rules.
Dynamic Entry: Fond of these, whether it's kicking down a love hotel door or jumping through Kimihito's bedroom window.
Your Door Was Open: Perhaps just as often she has a tendency to simply appear without warning or explanation, notably in the first chapter where the reveal that she's present startles Kimihito and again showing up suddenly among the rest of MON in Chapter 11.
Idiot Houdini: Kimihito suffers no end due to her irresponsibility, and she never suffers for it.
This finally backfires on her in chapter 13. She left her coworkers to cover her at work while saying it was to keep the other girls away from Kurusu while ill to avoid a viral mutation, when in fact she just wanted to slack off. Once she catches his cold, her coworkers refuse to help her for the same reason she gave them.
The Lad-ette: She's grossly irresponsible at her job, constantly bums off Kimihito for meals, and her own apartment's a sty.
Last Name Basis: With most of the cast, even though she does interact with them non-professionally.
Must Have Caffeine: Coffee, specifically Kimihito's coffee, is more or less her Trademark Favorite Food. The cheap instant coffee during a meeting is regarded as awful, the cheap instant coffee at his house the best.
Ms. Smith: I have a lot of different jobs. Looking for home stays, working as the extra-species exchange ministry's gun...er, 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!
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.
Those Two Guys: "Randomly show up to give the main characters grief" pretty much sums up their role.
The daughter of Rachnera's first host family, she tried to adopt Rachnera back into her family.
The Atoner: She wanted to readopt Rachnera out of guilt for her parents selling her.
Innocently Insensitive: She has a bad habit of insulting people without actively trying to. Kimihito even refused to let her adopt Rachnera because she kept treating Rachnera like a challenge to overcome instead of an actual person.
Turn the Other Cheek: Her response to everything that happens to her is to bring on the next challenge, such as repeatedly eating Miia's latest dish despite passing out each time.
Miia: The first human she met outside of the exchange program officials/agents (who don't count, as they're probably keep a strictly professional distance), whose first reaction to her was not to shun her for being a monster girl, but to be concerned about her getting cold due to her snake-like physiologynote So much that the first actual thing he does for her on her first day in his house is get her a big blanket to warm up the snake part of her body, because she was obviously discomforted by the air conditioning..
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.
Does Not Know Her Own Strength: Miia tends to strangle or constrict Kimihito to the breaking point by accident. Kimihito even reacts to her friendly pats on the back like he's getting punched. And when Lunacy strikes Miia, Papi and Centorea, all at the same time, they all suffer from this, thus leaving Kimihito facing a very real risk of literally getting killed during intercourse if the temporarily lust-crazed girls manage to capture him long enough to have their way with him.
Foil: Miia and Meron, Papi and Suu, and Centorea and Rachnera. This gets played up in the various date chapters.
My Significance Sense Is Tingling: When Rachnera arranges to move in, it cuts back to the house showing Miia, Centorea, Meron, and Suu looking horrified, and the first three all thinking "I just got the feeling another rival is about to show up...". Papi, as usual, seems to either not notice or not care.
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 which actually makes sense, as by Japanese transliteration rules, the katakana version of that is Miia, "Centaurea", and "Sue". (Papi is still romanized as "Papi", BTW)
From there, it appears the fan-translator decided that it would unfair/inconsistent to make an exception for her alone, and thus all three are still referred to as "Miia", "Centorea" and "Suu" in the fan translation.
Finally, Volume 1 of the manga got an official English translation, in which the names are spelled "Miia" and "Centorea," and Volume 2 has "Suu" and, adding in another example, "Meroune Lorelei" as "Meron Lorelei".
The Three Faces of Eve: Of the three girls who are in love with Kimihito, Papi is the Child because she is joyous, absent-minded, and a bit naive; Centorea is the Wife because she is incredibly honorable and chivalrous, as well as unerringly loyal to Kimihito; and Miia is the Seductress because she is very flirtatious, trying to seduce Kimihito on multiple occasions. They do however occasionally take on other aspects, and as the harem grows and they start trying to compete pinning one trait to any one of them becomes pretty much impossible.
Miia is a lamia and the first girl that Ms. Smith just dumped off on Kimihito. It didn't take long for her to fall in love with him and she has little problem turning on the charm to try to get him to make a move.
Bare Your Midriff: Not to the extent as Meron, but she finds a way to do this pretty often: she's outwardly stated that her waist is her best feature.
Blatant Lies: Claims that the Homestay Rules clearly state that the first girl to begin their stay at a home has privilege, basically saying she has officially-sanctioned first dibs on Kimihito. Nobody buys it.
Fangirl: Of the Metal Gear series, if her frequent cosplays as Solid and Naked Snake are any indication.
Fantastic Arousal: Her tail, specifically the tip. She was also very clearly aroused when Kimihito helped peel her scales off when she was shedding. The first chapter has Kimihito accidentally do this in an attempt to get her off him.
Fiery Redhead: The most passionate and romantic of the girls, and the only redhead.
First Girl Wins: While nothing has been set in stone, she is the favorite of both the majority of the fanbase and the author, and she's the most open to Darling. Really, it's more that she's built up to be the winner enough that her not winning would seem more contrived.
She invokes this herself to the other guests (see Blatant Lies above).
This seems to be the case as of Chapter 24, with Kimihito telling her if he survives he's going to marry her. It was most likely not serious, as it gets pointed out immediately after he's saying multiple things in rapid succession that are all Death Flags.
Freakiness Shame: She shows embarrassment when Kimihito sees her shedding. "Darling" tells her A) it's natural for her to shed and B) he's already seen her naked and this is less embarrassing for both than that (except it's not as lamia find being seen shedding far more embarrassing than nudity).
Girly Bruiser: Well, considering that she's an extraspecies, the incredible strength is a given. Miia however has proven herself to be capable at climbing trees, and judging by a couple of scenes where she goes into stances before a fight she apparently knows some manner of martial art. She's even a capable enough swimmer to keep up with a mermaid, though that was very reliant on clever tricks rather than pure athleticism.
Hoist by His Own Petard: Drastically lowers the temperature of the room she's currently in to try making Meron uncomfortable. She's the only one who has any issues with cold. Papi and Centorea aren't sure if she was going to kill herself or just end up hibernating, but Kimihito fixes the temperature before they can find out.
Hot-Blooded: Despite being physically cold-blooded, she's extremely passionate in what she does (i.e. wooing Kimihito). Ms. Smith even mentions it's a trait with lamiae.
She's never studied cooking in her life; Kimihito, Papi and Centorea find this out the hard way when Miia, trying to "teach" herself how to cook (by "emulating" what she saw from Kimihito's own cookwork in the kitchen), tests her culinary creations on Papi and Centorea, and incapacitates them for an entire chapter! Kimihito initially assumes that the food she made was traditional lamiae cuisine and ate it all.
In chapter 13, Meron eats some of her food, and the taste brings to her mindthe idea of how it would feel to have her fins torn apart. (In context, it's a reference to the Sea Witch's potion in Little Mermaid, which is what Meron's subconscious opinion of the meal is - i.e it's a incredibly dangerous, painful concoction you probably shouldn't put into your mouth.)
Chapter 25 provides an explanation for Miia's horrible cooking: as a carnivore, Miia's sense of taste is far less sensitive than a human's, making it difficult for her to judge the quality of her cooking.
Miia's inability to taste food is further compounded by her incredible lack of judgment in cooking. Her recipe for white rice gruel includes things such as white peach, white icefish, and white chocolate (in other words, ingredients chosen simply because they were white)! And more recently, she added peanut butter to miso soup on the basis that she thinks it looks like miso.
Logical Weakness: As mentioned in chapter 1, her being part-reptile makes her susceptible to cold temperatures, and she requires warmth to stay healthy. Even in a heated swimming pool, over time she'll become sluggish.
Loveable Sex Maniac: She really wants to get into Kimihito's pants. She even tried to strip Kimihito while he's sick!
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.
Super Strength: She can crumple steel in her coils with virtually no effort, often without even realizing it. Justified assuming that unlike a snake, all her major organs are probably up in her human half, making her tail a huge mass of solid muscle and bone.
The Tease: It becomes clear very quickly that she doesn't give a crap about the no sex rule of the exchange program as she tries seducing Kimihito fairly regularly.
She once outright stated, while laying naked on the bed, that she wants him to take her virginity.
Chapter 2 has her gleefully pulling Kimihito into a lingerie shop and taking off her top in front of him, asking his opinion on the bras, and dragging him towards the changing rooms with her. All with a smile on her face.
Tsundere: Type B. She's sugary-sweet to Kimihito, but she can be violent when provoked (especially by romantic competition, i.e. Papi and Centorea).
Weaksauce Weakness: Cold. Justified as she's a lamia, i.e. a reptile. It's also dangerous for her to be in large bodies of water for this reason; while she can swim quite well, it's harder to maintain her body temperature in a pool, even if it's a heated one.
Your Size May Vary: The length of her tail, which varies from being several feet long to closer to twenty feet, though according to Chapter 17 her body is eight meters (just over twenty-six feet) long in total.
A harpy and the second girl to end up living with Kimihito. She's childish, both physically and mentally, despite being as old as Miia.
Accidental Truth: When she was first introduced she mentioned that she was informed that if she kept flying away she was going to get "deflowered". A few chapters later she, with the help of Miia and Centorea, runs off with Suu who proceeds to do just that to the three of them.
The setup for this is not present in the official English version, mistaking deported as aborted rather than deflowered.
Adult Fear: She watches the girl she saved early in the series get run over by a truck, who was only saved because Suu managed to wrap her up and absorb the force of the impact. Before they can get Suu unstuck from the side of the bridge they were on, it collapses dropping her into the river and because of her hands not being strong enough to hold people and Suu being slippery she can't do anything but watch her fall.
She also tends to focus on completely random minor details. While watching a news report on a hostage situation and how it'll be affecting the Extraspecies Exchange Laws, Miia and Centorea discuss that. Papi on the other hand.
Papi: "Huh? Isn't that Ms. Smith?... That is Ms. Smith."
Femme Fatalons: Her wings have exposed thumbs like a bat each ending in a sharp black claw.
Heterosexual Life-Partners: After Suu starts living at Kimihito's house, the two of them are rarely seen without the other; she even spends the majority of Chapter 12 trying to find Suu rather than deal with anything else that's going on. The pair are often seen providing various Funny Background Events while ignoring the drama from the other girls.
Idiot Hair: ...Well, as unkind as it might be to be blunt about it…
Immodest Orgasm: Papi has one when Suu gets too touchy with her after she gets wet. She also has one when Kii wraps her bondage-style in vines and tightens them.
Innocent Fanservice Girl: Papi has no concept of modesty, as she dives into a public fountain naked thinking it's a bird bath.
Ambiguous Innocence: As Centorea points out, she's nowhere near as young as she looks, and is never above trying to use her apparent naivete as an excuse to jump Kimihito.
Older than They Look: Harpies look like young teenagers even as adults for the sake of flight. In reality, she's just as old as Miia, which the latter doesn't take too well when Papi drags Kimihito into the bath together.
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.
Winged Humanoid: The "wings-for-forelimbs" variation, but the digits of her wingsnote Yes, birds do have "hands" in their wings in real-life. 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.
Big Eater: She usually manages to keep her appetite in check, but if she eats something she really enjoys, she'll gorge herself with reckless abandon. This got the entire group banned from a restaurant once.
Clingy Jealous Girl: She may think of it as beneath her, but deep down she's just as clingy to Kimihito as much as Miia is. This comes to the forefront in Chapter 16.
Courtly Love: Since she thinks of herself as a knight, she tends to think of her relationship with Kurusu along these lines: she loves him, but expressing that love or pursuing him would be un-knightly.
Cute Clumsy Girl: Though usually quite coordinated, Centorea becomes very clumsy and accident prone when she's feeling nervous or shy. The fact that her enormous hindquarters tend to smash into things can be a problem.
Expressive Ears: In chapter 25 they wriggle as she was eating carrots given to her.
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.
Cerea, unlike Miia, actually does know how to cook. Unfortunately, it's centaur food, which is large amounts of mostly-raw vegetables. It's very healthy and filling, but also rather bland.
In chapter 25 it is revealed that being a herbivore, her sense of taste is 2-4 times more sensitive than a human's, which could justify her food in chapter 21 being rather bland to non-herbivores like Kimihito and Rachnera.
Only Sane Woman: In Chapter 12, she more or less spends the entirety of Miia's jealous rampage pointing out just how crazy she's acting. In general, she's the reasonable girl of the lot, who doesn't try to push Kimihito around as much as the others.
Phenotype Stereotype: Blonde-haired, blue-eyed girl? Check. Foreigner? Check (she's most likely from Europe given her knightly background).
Token Wholesome: Centorea actually dresses and acts very properly. It's just that being stacked like a snow fort makes modesty... difficult.
Wrong Genre Savvy: Slimes are not the easiest things to kill despite what RPGs have told her, much to her disappointment. Later, she assumes "D" might be a "devil," and shows up to her date in full plate armor ready for a fight. When she does encounter a devil on her date, it isn't "D", and it isn't what she expected either.
A slime girl who just randomly showed up one night at Kimihito's house. She seems to mostly mimic the behavior of those around her.
Ambiguous Innocence: While she was mostly unaware of right and wrong at first, Suu has probably figured out more of it as the series goes on, despite continuing with the tentacle rape and such. Notably, she seems to only talk with Kimihito when none of the other girls are watching.
Black Comedy Rape: She gets very touchy with the other girls whens she gets hungry and they get wet, to the point of inducing Immodest Orgasm. Even a drop of sweat will cause her to violate them. Her response when Draco attacks Kimihito is to go tentacle-monster on her.
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.
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.
Capable of eating Miia's horrifying food with no ill effect. She can also absorb body fluids and liquid fertilizer.
Kimihito asks her to help him pick mushrooms due to this. Even after eating a few poison mushrooms, the only side effect is poisoning her speech and making the water she spews out as an attack poisonous.
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.
As she's made entirely of some liquid-like substance, she becomes "diluted" when submerged in a bathtub-sized body of water, and takes time to reform and drag herself out of it. If she falls into a huge enough body of water (e.g. a river) or gets caught in a heavy storm, however, the dilution effect would be serious enough to kill her.
On the opposite side of the coin, dehydrating her shrinks her and makes her lose her humanoid form and revert to a compact blob, but doing so is akin to starving her. Most of the hijinks revolving around her involve her attacking anyone with even a trace of moisture on them.
Loveable Sex Maniac: While it's not specifically sex that she's after, the other girls consider her to be one and tell Rachnera to get used to being violated by her.
Morphic Resonance: Regardless of whether she's in blob, child, or adult form, or mimicking another person or object, she always has her antenna.
New Powers as the Plot Demands: Suu has done this a lot throughout the series, helped by the fact that she's a non-mythological monster without defined powers, and by the fact that hers is a new species about which little is known.
Obfuscating Stupidity: While no one is sure how long she's been able to, she accidentally reveals that she can speak in more than just mimicked phrases. As soon as she's called out on it, she goes back to mimicking.
She's also the one to put the kibosh on the Director's plans to sell Papi's egg (and more than that, her dignity) by reading his mind and broadcasting his true intentions for all to hear.
Chapter 20 reveals that her intelligence is based upon her size. As a blob able to fit in a bucket she's essentially just running on instinct, in her base form her intelligence is that of a child, and in kaiju form she's able to make scientific deductions based on her surroundings. Though in Chapter 25 her "child" form is still able to hold a conversation once out of sight of everyone but Kimihito, and makes rude insults when taste-testing possibly-poisonous plants has given her a "venomous" tongue.
Telepathy: In addition to knowing the emotions of people she's touching, she can see their memories as well.
Too Kinky to Torture: Rachnee wanted to play "games" with Suu and Papi while the others were at the health club, but apparently the end result is Rachnee exhausted and Suu and Papi happily swinging around in arachne webs.
Voice Changeling: She can mimic a person's voice precisely depending on the persona she takes on.
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.
A mermaid and the fourth girl to officially move in with Kimihito (Ms. Smith has, unsurprisingly, considered Suu to not be her problem). Wheelchair-bound for obvious reasons when out of the water, she first meets Kimihito when she loses control of it and he saves her. After she helps him find the other girls, it's revealed the waterproof room being built in Kimihito's house wasn't for Suu at all; instead it was so Ms. Smith could dump her off on him.
Adorkable: Not quite to the degree of Centorea, but Meron has her share of awkward moments, mostly her being Innocently Insensitive. Examples include when she interrupts what would have been Kimihito and Miia's first kiss with fish trivia, or when she cheerfully tries to compliment Miia by saying she "swam like an eel."
Bare Your Midriff: When not wearing her maid outfit, she spends most of her time around the house in a bikini top, probably so she can slip easily in and out of the pool in her room whenever she wants.
Be Careful What You Wish For: After seeing Kimihito and Miia's lovely date together in Chapter 19, Mero discovers the feelings of jealousy and loss—and they're not what she expected, even though she wanted it to happen.
Charm Person: Perhaps further hinting at her royal origins, she possesses a compelling regal aura capable of making people genuflect when speaking.
Covert Pervert: Doesn't really mind getting tied up by Rachnera since it feels good to her.
Crash into Hello: Kimihito plucks her from her runaway wheelchair and ends up smashed between her and a pole during their first encounter.
Everything's Better with Princesses: Maybe. Centorea and other people she meets certainly get that vibe from her, and she does seem to know an awful lot about knights and nobles.
Modest Royalty: In the "dresses like a commoner" sense, not in the "too modest to spend an entire chapter either in a bikini or out of it" sense.
Exact Words: Done during a conversation with Miia; at first it comes off as her exposing herself as a Yandere, but in retrospect is in fact her admitting she only wants second place.
Miia: Well, anyway!! I'm going to make sure you don't get your hands on my Darling! Got it?! Meron: Oh, don't worry. The feeling...... Is mutual.
Innocently Insensitive: Sometimes. She's sincere in her compliments, it's just her choice of words are usually... poor.
Meron: "There, there, Miia-sama was amazing as well. You swam just like an eel!" *totally innocent*
Limited Wardrobe: Says she only has her Gothic Lolita outfit to wear in chapter 23.
Logical Weakness: Given that mermaids breathe water, the purity of the water is important. Swimming in chlorinated water is dangerous to her health; it would be the human equivalent of breathing in bleach fumes.
Love Epiphany: She has one at the end of chapter 19, after Miia and Kimihito's date at the aquarium. This after claiming to only want to experience a tragic love like in The Little Mermaid.
Marshmallow Hell: It's what Kimihito gets after saving her from her runaway wheelchair in their first meeting.
Moment Killer: She accidentally does this to Miia and Kimihito in Chapter 19.
Nightmare Fetishist: Wants to experience a "tragic love" like in the original Little Mermaid story, including turning into sea foam! However, she doesn't enjoy actually experiencing it in chapter 19, and in Chapter 24 shifts her priorities to having Kimihito's children so that she can raise them without him.
Our Mermaids Are Different: Apparently they have webbed hands, fin-like ears, gills along their rib cages, and a pronounced set of pelvic fins. Also they can survive on land so long as there is a decent amount of humidity, and give off a mucus-like secretion to retain moisture.
Mermaid Problem: Not an issue, if her attempt to copulate with Kimihito in Chapter 24 is any indication, and in hindsight her clothes do cover the part of her body one would expect.
Shipper on Deck: She wants anyone but herself to be with Kimihito, primarily Miia as she was the only one to openly acknowledge being interested in him.
Skinship Grope: Inflicts this on Miia at the end of her debut chapter while the two are reconciling.
Too Kinky to Torture: After eating some of Miia's cooking, it brings to mind having her fins painfully split apart into legs. Afterwards, she is seen collapsed on the floor smiling about it, despite foaming at the mouth. Later, once Rachnera ties her up, she finds herself rather enjoying it.
Someone to Remember Him By: After realizing that it wasn't all it was cracked up to be, and believing that Kimihito was soon going to die, she immediately tried to seduce him in order to have this sort of tragedy instead.
Unrequited Tragic Maiden: She wants to be one. She doesn't want to be a third lover though; there's no tragic romance when it comes to third place.
Wardrobe Malfunction: Mermaids secrete a slime to keep themselves moist. The result causes this to happen.
Waterfall Puke: Afflicted with this when she starts getting chlorine poisoning from the pool.
An Arachne and the fifth girl to officially move in with Kimihito. Her original host family had sold her off to the director because they were expecting a monster girl who wasn't so...monstrous. This and the director's behavior left her hating humans, until she met Kimihito.
Action Girl: Miia jumps at her when she first shows up and tries to put the moves on Kimihito. She's completely restrained in webbing a panel later with Rachnee ignoring her outright.
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.
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.
Broken Bird: From what can be seen of her in a flashback, she was not always bitter towards humans.
Brutal Honesty: Rachnera generally does this as she doesn't like sugar-coating things. Such as when she tells Centorea her sandwiches are not very good because she just put chopped raw vegetables between two pieces of bread.
Casual Kink: Really enjoys tying people up much like a dominatrix would. And she enjoys testing new methods on the other girls.
Cuddle Bug: Separate from her love of tying others up she tends to get very tactile with Kimihito when she's in a good mood, to a point that rivals even Miia. She especially seems to like caressing him, which is quite impressive given how sharp her claws are and how she manages to do it without injuring him. She makes ample use of her breasts as well. Kimihito can't seem to bring himself to object to this all that much.
Femme Fatalons: Sort of. Her arms are covered in a black carapace from the shoulders down, and the gauntlet-like plating on her digits end in sharpened points.
Freakiness Shame: Not so much shame as realizing people may be put off by her spider parts. Kimihito admitting that he finds her legs charming is part of what gets her to realize he's not a bad person at all.
Freudian Excuse: After her rejection from her first host family and being sold off into slavery, she's very bitter towards the human race and slow to trust anyone.
In chapter 26 it is explained that she accidentally harmed the daughter of the host family, Ren Kunazuki. The incident made the parents thought it was impossible to live with her and sold her.
Humans Are the Real Monsters: Her general opinion on them. She tries to prove that Kimihito is no different, and eventually opts to arrange to move in with him when she finds out that he is, in fact, a decent person who doesn't discriminate against non-humans.
Hypocritical Humor: Calls Kimihito a hypocrite for getting turned on by her human parts, believing that like other humans, he finds her spider half disgusting. When he states he finds her legs to be "charming," she laughs at him and calls him a pervert who gets turned on by spider legs (and given that none of the monster girls he lives with have normal human legs if they have legs at all.....).
Obviously Evil: Subverted. She has a massive skull design on her spider-like body and dresses like a Femme Fatale, and her first appearance involves more or less mummifying a man and expressing an implied violent interest in Kimihito. She kidnaps him, binds him in webbing, and suspends him from the ceiling repeatedly. She's actually just a rightfully bitter person who's been screwed over by humans repeatedly, looking for one that's actually decent and worth living with.
Played up by Rachnera when called for. She is aware of how dangerous she looks and has no qualms about using this to her advantage.
Offscreen Teleportation: Seems to move very, very fast when not in a frame. For instance suddenly appearing on the ceiling when she was on the floor a moment ago. Justified by the fact that fleeing spiders are pretty quick.
Pay Evil unto Evil: When she finds out that there might be a decent human, Kimihito, she turns on the director, encasing him in webbing and leaving him for the police to find, and proceeds to use that time to abduct and investigate Kimihito.
The Tease: Kind of a lot, actually, even by this manga's standards. She pretty much starts putting the moves on Kimihito - albeit in a mocking fashion - even before she moves in. Once she does move in, she spends an entire day trying to get into his pants.
Token Evil Teammate: She's not evil per se, but she does enjoy tying up the other girls, except Suu, who she's unable to bind at all. And when she first ties up Lala, she's unable to get a response due to the latter missing her head at the time.
Underboobs: So much so that the first time Kimihito was on the ground looking up at her, her nipples were totally exposed. Even her more casual articles of clothing leave a generous amount exposed.
A Dullahan, the second "D", and the sixth girl to officially move in with Kimihito. She initially introduced herself as a grim reaper who was there due to Kimihito's impending death, when in fact she merely enjoys pretending to be a grim reaper and really showed up because she was on the run from Ms. Smith and fascinated by Kimihito's apparent invulnerability.
Badass in Distress: Her head and body being so far separated keeps her from using her powers. This would normally not be much of a problem according to her, but she doesn't have the time as she's being hunted by "The Organization".
It's revealed in Chapter 24 that the so called "Organization" is just Ms. Smith doing her job of making sure that she isn't running off on her host families.
Bait and Switch: Initially implied to be the second "D", she actually arrived to warn Kimihito about his impending death. When questioned about the note, her response is that her only purpose in interacting with mortals is to warn them of their deaths, so it was assumed she did not write the letter. It's then revealed she really is the second "D".
Black Eyes of Crazy: She has black sclera and is sinister and morbid, but like Doppel and Lilith she's not evil.
Glowing Eyes of Doom: While her head is on her shoulders, they appear normal. Once she's carrying her head in her hands behind Kimihito they appear to be glowing. After being revealed completely, the glow is gone.
Gory Discretion Shot: Her neck stump looks just as you'd expect from a normal decapitated body, to Miia's horror.
Goth: Turns out that this is basically what she is. Her speeches about being death and unstoppable and such is the same sort of thing you hear from some angry kid discovering black makeup for the first time—her ability to pull her own head off just gives her a bit more dramatic strength.
The Grim Reaper: She's a Dullahan and refers to herself as both "Death Incarnate" and "The Huntress of Death": ultimately, it's averted, however. In the end, she's just a Monster Girl no more supernatural than the rest of the girls, and her connection to Death is her just playing pretend.
Headless Horsewoman: She's a Dullahan, this comes with the territory. No word on if she has a horse or bike though.
The Immodest Orgasm: Courtesy of Rachnera and Suu on her body while Kimihito and a few of the girls are looking for her head.
Losing Your Head: She lost her head approaching Kimihito and had to get his assistance in finding it as it went rolling downhill and into a park.
Ms. Imagination: Turns out that all her death talk and being a grim reaper is just delusional banter equivalent to 8th grader syndrome.
Offscreen Teleportation: She manages to cross a street and get behind Kimihito in the time it took for a truck to pass by breaking his line of sight on her. She pulls it off again when chasing him and the other girls down. She had Rachnera's assistance that time.
Justified since in the Irish tales, once a Dullahan is after you, you will not get away unless you throw gold at them.
Red Oni, Blue Oni: An interesting case where the head is blue and the body is red. Her head acts calm with little emotion but the body, ironically, is more expressive when they are separate.
Sinister Scythe: And she uses it to apparently prepare to decapitate Kimihito, hooking him around the neck as the chapter just ends. Turns out she did this to get his attention. It apparently has an indent in it.
Shown Their Work: The girls mention a "horse-drawn carriage with a headless rider" and the image showed the horse also missing its head. In certain tellings of Dullahan stories, this is another way they can appear.
The Leader: Ms. Smith tends to be the one orchestrating how things should play out, though being human leaves her typically unable to directly assist.
The Lancer: Zombina, being declared the group's commander, is in charge of more immediate matters for MON while actively working.
The Smart Guy: Doppel; being required to know how she needs to look and act to deceive enemies puts her in this role.
The Big Guy: Shared between Manako and Tionishia. Manako has shown the ability to quickly disable a large number of enemies, while Tionishia is noted to be the strongest of the group and utilizes that strength to bypass things like walls.
The Chick: Shared between Manako and Tionishia. Manako feels that she's not really considered part of the group for being required to stay at a distance and her specialty requires the element of surprise so she can't repeatedly assist the group on the same mission. Tionishia, despite her strength, is more used simply to guard and escort hostages and can be seen trying to keep the group from fighting amongst themselves and attempting to boost morale, especially Manako's.
The official English version has it stand for "Monster Ops: Neutralization".
Pretty Freeloaders: In Volume 3's extra, Kimihito and Meron point out that they spend a lot of time at his house. And in Meron's pool specifically.
Ragtag Bunch of Misfits: They have varying degrees of professionalism and wildly different personalities, but they're pretty competent at their jobs.
Single Woman Seeks Good Man: Strongly hinted at at the end of Chapter 22. Zombina, Tionishia, and Manako all admit to having enjoyed their time with Kimihito, and immediately switch the conversation to looking into doing the homestay thing as well when their boss is notorious for just dumping more and more girls into Kimihito's home.
A living dead and commander of the squad.
Alien Blood: Her blood is a special anti-decomposition fluid made from a formaldehyde base and is circulated by an artificial heart. The fluid is hazardous to the living.
Blood Knight: She's shown to be enjoying herself during the hostage situation in chapter 11, and at the end of chapter 15's hostage situation her only concern was that she didn't even get to shoot someone.
Butt Monkey: In chapter 20, she spends most of the time getting stomped on by giant monsters, culminating with her buried in a crater. It's okay though, since she's already dead.
Deliberate Injury Gambit: She used being gunned down and left for dead to her advantage to later surprise the orcs with the fact that she was not really dead (well, permanently) and also very much armed.
Fangirl: Enjoys zombie films, and after seeing one on her "date," begins enthusiastically discussing the various tropes and trends of the genre.
Feel No Pain: She explicitly states it while hanging out with Kimihito. Whether she can feel... other things is more ambiguous. Now, considering the fact that she moaned when Kimihito inadvertently pinched her nipple and her embarrassment that she did so the evidence suggesting that she can feel pleasure is rather solid.
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.
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.
Mix-and-Match Man: While she refers to herself specifically as a zombie, her appearance gives off the impression of being put together from parts from multiple corpses. Her heart and blood are artificial, and her left eye is a transplant.
Nigh-Invulnerability: Par for the course, considering she's an undead. She can shake off bullets with ease as stated above, and getting crushed by two kaiju didn't seem to have done any lasting damage.
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.
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.
Oddly Visible Eyebrows: Perhaps one of the few examples with an explanation. As stated above, her hair will always appear conveniently placed. Apparently this includes being "behind" her eyes so as to not obscure them.
Nice Job Breaking It, Hero: Not only did it backfire spectacularly by allowing Kimihito to get even closer to all the girls, but it also seemed to have sparked an interest in him among her coworkers, and worst of all it ensured that when a real threatening letter came in MON didn't realize it was from a different source until it was too late.
Hyper Awareness: She's incredibly observant about the people and things around her, such as noticing slight changes in a person's gaze or being able to snipe despite having no depth perception. She also spots "D" stalking the MON dates, likely even before the reader; Checking a clothes rack while Kimihito speaks with Zombina on Tionishia's date, checking some books to the left of the drink bar on Zombina's date, and finally twice during her own date buying a hot dog and hiding behind a vending machine while watching them.
Punny Name: Manako sounds very similar to the word "monocle", an eye-wear meant for a single eye. It is also a Japanese word for "eye."
Running Gag: Several chapters that she's shown up in, she's made comments about her eye hurting or being dry while tearing up. Her insecurity over how people might treat her over her eye comes up often as well.
Shrinking Violet: The shyest and most insecure girl of the series, not just MON.
Super Speed: She manages to cover the 2km distance on foot in just a matter of minutes and implies it would've been less but her enormous gun slowed her down.
Youkai: It should also be noted that Manako shares more in common with the youkai Hitotsume-Kozo than anything from Classical Mythology. (Including having childish proportions in contrast to being a giant)
An ogre who serves as hostage escort/guard of the squad, due to her immense size and power.
Big Eater: Literally. Her massive size probably has something to do with her appetite. She's been known to eat entire cakes, as well as ice cream by the liter.
Boobs of Steel: The physically strongest member of MON as well as the bustiest.
Dark-Skinned Blond: Usually how she's drawn, though we haven't gotten a color picture yet.
The Fashionista: The majority of the money she makes is stated to go into buying clothing and accessories, in part due to needing everything custom made. Manako's profile states that the entire group has high standards for fashion, but notes Tionishia as having the highest standards.
Gag Boobs: So massive they make Centoria's look normal by comparison. Her profile lists her as being a P Cup, and that that's large even among Ogres. Her bras are custom made and reinforced, described as a "marvel of modern engineering".
Genki Girl: Drags Kimihito from shop to shop all over town on their "date."
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.
Statuesque Stunner: She's noted to be at least 7 feet tall, and in comparison to Kimihito is a coupleheads taller. Even among most monster girls she's apparently large, as the clothes at a store specifically stocked for extreme sizes were still too small for her.
There Was a Door: Justified. Going into a hostage situation straight through a door would not be the wisest of ideas.
Youkai: The only monster so far with an Asian origin, though there is a rough Western equivalent. The English version simply refers to her as an Ogre.
A kobold who runs a fitness center for extraspecies, and the first non-government monster girl to NOT be added to the harem.
Reasonable Authority Figure: She is genuinely concerned with how the fitness center will be received and when issues are brought up, such as Mero not handling the chlorinated water in the pool well or the temperature being too cold for Miia, she says she will make sure when the place opens to the public, they will be fixed.
A unknown individual who has sent Kimihito a death threat. Revealed to be two people Doppel and Lala. For further details see their entries.
Bait and Switch: So far it's been assumed that Draco, Kii, Lilith, and Lala were "D". After her initial reveal presents her as being innocent, she immediately slips into the same behaviors as in her note in the following chapter, revealing that Lala was the second "D" after all.
The Ghost: Up until The Reveal, they had not been seen. All that's known about them is the note.
Purple Prose: Though not all of it can be seen the second note is quiet poetic, especially compared to the original blunt threat of the first. This hints at the fact that it's not the same "D" as the initial writer who was revealed to be Doppel pranking them.
I will bring death upon you. Death will bind us. ~ Together with you, I want to be together ~ Instead of allowing you a short life ~ me. We will spend life in eternal dark ~ now, time will fly like the wind and ~ lusion. The eternity of death wil ~ e.
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.
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.
Immodest Orgasm: When Papi and Kimihito suck the fertilizer out through her breasts, she has one.
One-Winged Angel: After absorbing experimental fertilizer for several months, she transforms into a massive plant monster.
Overnight Age-Up: Exposure to the experimental fertiliser caused her to grow from looking like a small girl to a buxom young woman. She reveted once the chemicals were out of her system.
Plant Person: She's a dryad, who looks mostly human with plant features such as leaves and vines for hair and bark covering her arms and legs.
Plot-Relevant Age-Up: Normally looks like a child, but after absorbing experimental fertilizer, she gains a body of a busty adult (which happens to be inside a giant tree monster body). She gains this form naturally when she's met again in Chapter 25.
Outside-Context Villain: Unlike the other one-off villains so far, Lilith has no real motive beyond causing mischief for her own amusement and doesn't seem to have a host family she's staying with.
The Prankster: Continuously pranks Centorea and Kimihito throughout Chapter 21, undergoing Serial Escalation until she brainwashes Centorea into trying to rape Kimihito. It bites her in the ass when she presses Rachnera's Berserk Button.
