Affectionate Nickname: Miia calls Kimihito "Darling", Papi calls him "Husband" ("Boss" in the English manga), Centorea and Suu call him "Master", Meroune calls him "Sir", and Rachnera calls him "Honey." Ms. Smith calls him "Darling" too because she finds it amusing.
Only Known by Their Nickname: His actual name is mentioned only once or twice, otherwise it's always Darling, Husband, Master, Sir, or Honey.
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.
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 Meroune. 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.
Got Volunteered: Ms. Smith pretty much just dumped Miia, Papi, Centorea, and Meroune at his house.
And Rachnera basically blackmails Ms. Smith into doing this again after the latter's lack of attention led to her host family not being prepared for her, which led to her being 'sold'.
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.
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.
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.
Nice Guy: The driving force behind each of the girls falling in love with him.
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.
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.
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.
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.
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.
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.
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!
Fantastic Racism: Pretty much all they do is throw bigoted insults at the monster girls just for the sake of messing with them.
Gang Bangers: The man in the couple seems to be one of these.
Gonk: Look at all the other humans. Look at all the other monster girls. Now look at them.
Jerkass: They don't limit their dickery to monster girls; other humans are also targeted by their harassment.
The man upgrades from harmless, if annoying Jerkass to out-and-out villainy in chapter 17, 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...
Laser-Guided Karma: Whenever they show up, expect something bad to happen to them very soon.
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.
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.
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".
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 has little problem turning on the charm to try to get him to make a move.
Bare Your Midriff: Not to the extent as Meroune, 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.
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).
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.
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.
Hoist by His Own Petard: Drastically lowers the temperature of the room she's currently in to try making Meroune 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, Meroune 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 Meroune's subconscious opinion of the meal is - i.e it's a incredibly dangerous, painful concoction you probably shouldn't put into your mouth.)
Logical Weakness: As mentioned in chapter 1, her being part-reptile makes her susceptible to cold temperatures, and 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).
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 temperatures in a pool, even if it is 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.
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.
Big Sister Instinct: She's rather protective of Suu, even flying off with her when the others think about giving her up.
Mama Bear: It's noted that her motherly instincts are really strong. She ends up switching between the two depending on the situation.
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.
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.
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.
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.
Large Ham: Has a habit of being melodramatic. She even compares her meeting with Kimihito to the meeting of Hercules and Chiron.
My Friends... and Zoidberg: Miia draws up a diagram explaining everyone's connections when they think the government is after Suu. Centorea's place on this is simply marked as "?".
Occidental Otaku: A lot of her assumptions on how things 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.
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).
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 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.
Extreme Omnivore: Capable of eating Miia's horrifying food with no ill effect. She can also absorb body fluids and liquid fertilizer.
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.
Morphic Resonance: Regardless of whether she's in blob, child, or adult form, or mimicking another person or object, she always has her antenna.
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.
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, 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: 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.
Crash into Hello: Kimihito plucks her from her runaway wheelchair and ends up smashed between her and a pole during their first encounter.
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*
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.
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.
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.
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.
Wardrobe Malfunction: Mermaids secrete a slime to keep themselves moist. The result causes this to happen.
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...monsterous. 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.
Casual Kink: Really enjoys tying people up much like a dominatrix would.
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.
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 stated he finds her legs to be "charming," she laughs at him and calls him a pervert who gets turned on by spider legs (truth be told, 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 in 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 him.
The Leader: Ms. Smith tends to be the one orchestrating how things should playout, 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: Dopple, 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.
Ragtag Bunch of Misfits: They have varying degrees of professionalism and wildly different personalities, but they're pretty competent at their jobs.
A living dead and commander of the squad.
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.
Frankenstein's Monster: While she refers to herself specifically as a zombie, her appearance gives off the impression of being put together from parts from multiple corpses.
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.
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.
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.
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 chlorinated water in the pool well or the temp too cold for Miia, she says she will make sure when the place opens to the public, they will be fixed.
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.
