Kimihito seems to excel at certain household chores and activities: his cooking is so good that the liminal girls living with him put on weight, and he proves to be quite skillful with needle, thread and sewing machine.
He is also not afraid to unhesitatingly put himself in physical danger to protect or save his liminal house-guests, whom he thinks of as family, as demonstrated on several occasions such as bodily shielding Centorea from a sword attack[ch.
He rarely shows any anger towards anyone, especially the girls, but when he does he demonstrates a surprisingly strong assertiveness, two of the most notorious examples occurring first because the Couple (see "Supporting Characters" below) insulted Miia[ch.
She has red hair, golden eyes with vertical slit pupils and pale human skin, and her snake part has copper scales with a pinkish-cream underbelly (the tip of her tail is particularly sensitive).
She has a pleasant personality and harbors a very strong crush (both figuratively and literally, considering that her species is a constrictor) on Kimihito — actually on the brink of the obsessive: all lamia are female — they need a human male for procreation and are very passionate about their partners.
She is not a good housekeeper and an abysmal cook; on several occasions, she accidentally gives the other household members food poisoning, due to her sense of taste being far weaker than a human's and her frequent use of "alternative" (but inappropriate) ingredients.
She is petite and physically appears to be much younger than the other girls, even though she is actually the same age as them (harpies have evolved with smaller, slimmer bodies to enable flight and generally have a much less mature manner than other races).
She is good-natured, happy and playful, but she is unfortunately a "birdbrain" with a very short attention span (taken to an extreme as she will sometimes forget anything she was doing after only taking three steps and even less long-term memory [however, in Chapter 28 after being carried by Kimihito for a distance she was able to remember a great deal about her past]),[ch.
Originally, the harpies were reluctant to take part in the Interspecies Cultural Exchange Accord program; however, Papi ran away from home "to give it a try" and seems to be the first of her species to want to remain permanently in one place with one human male.[ch.
9: "Monster Musume Technicolor 'Kemomo' Side Story"] Her demeanor and language is that of a medieval knight, and she has sworn herself to be Kimihito's servant through a series of misunderstandings after they crashed into each other by accident and later chased a motorcycle-riding purse snatcher together.[ch.
Voiced by: Mayuka Nomura (Japanese); Monica Rial (English)[5][6][2] Suu (スー, Sū) is a Slime, an amoeba-like creature that can change shape and color without effort, and the fourth to join the group.
Her basic shape is a glob with two dark eyespots that tend to glow like cat's eyes when backlit, and with a single pseudopod on top, which she can use to read peoples' thoughts and feelings on contact.[ch.
13] Her race is a type of liminal currently not fully classified under the Accord (making her an "illegal alien"), and she enters Kimihito's home without permission or Ms. Smith's knowledge; the rest of the household (mostly Papi) take pity on her and want her to stay.
54] Suu usually wears a yellow rubberized raincoat and boots (given to her by Kimihito) out of necessity as any other clothes will get soaked in slime, and all small objects will pass through her membrane skin and stay suspended in her body fluid.[ch.
16] Rachnera enjoys annoying most of the household and hones her web-making skills by setting traps for everyone which typically result in them being unwillingly tied up in bondage positions (except Lilith [see below], who turns out to be a masochist).[ch.
When she first appears, she pretends to be a "shinigami" (the near-equivalent of the Grim Reaper), and the girls actually believe the story (she initially enters the house without her head — it had fallen off and rolled down a hill into a park).[ch.
This, coupled with his genuine kindness towards the girls, has caused Lala to fall for him as well, though she refuses to fight over him: by her reasoning, as a dullahan she will take possession of his soul once he finally dies, and they will be together then.[ch.
She acts and moves like a normal person (except when she remains immobile for a long time [including sleeping], then her body stiffens into a rigor mortis-like state; she is supposed to do tai chi-similar exercises to prevent this, but frequently forgets to do so).
3: "Doppelganger: Doppel's Delights"] Her usual form is that of a 14 to 18-year-old girl with grey-brown skin, clad only in a whirl of her own ankle-long white hair, and her sclera are black (her true appearance is unknown, but is hinted to be very Lovecraftian[ch. 40]).
40] Voiced by: Keiji Fujiwara (Japanese); Steven Finley (English) A human and a con artist who claims to be associated with the exchange project and bullies his way into Kimihito's house on the pretext of making a documentary while using the alias "Kasegi".
20] After Kii has grown to a gigantic size and become deeply resentful of humans, Papi, Suu and Kimihito manage to detoxify her (removing the toxic nutrients from her body via a very embarrassing method) so she becomes normal again.
41] Voiced by: Airi Ootsu (Japanese); Rachel Landon (English)[7][2] Draco (ドラコ, Dorako) is a Dragonewt, a lizard-like creature with dragon wings (which are not strong enough to allow her to fly) and a powerful tail.
40] In Yoshino Origuchi's light novel Monster Girls on the Job (2020, Seven Seas Entertainment, ISBN 978-1-64827-559-3-shows up at the Bar Zerro N (where she seems to be a regular customer) and a few nights later at Polt's casino as a roulette croupier.
31] Thanks to the help and some ideas from Kimihito and the girls, the Sno-Ball Inn becomes a highly successful venue for humans and liminals to meet and interact, especially for "Mix 'n' Match" couples events.[ch.
35] They are totally terrified of being blamed for anything, and when Mero went missing they simply stayed back while Kimihito and the girls did all the work, since they didn't wanted to lose their jobs for trying to bargain with Octo on a previous occasion.[ch.
39] A Jiangshi from Taiwan and an old acquaintance of Zombina (since they're both undead) who is apparently desperate to get herself a Japanese marriage partner in order to attend fujoshi/yaoi events more easily; hence she would frequently smuggle herself into Japan despite strict supervision by the Cultural Exchange Bureau.
Despite this and because she wanted to make friends, Kino contacted an underworld broker (later revealed to be the President of Black Lily Innovations [see below]) who illegally smuggled her into the country alongside Kiira and a third liminal.
She is of medium height, with long straight silver-colored hair and pointed ears, and wears a floor-length caped robe with a blue-and-gold ornate collar (which hides both her bat-like wings and her A-cup breasts),[vol.
56] However, he is more than able to hold his own against Ms. Smith in an argument over liminals and the ethics involved between how the Interspecies Cultural Exchange program supposedly helps liminals and how his business supposedly helps them, and he is very skillful at exploiting loopholes in the Interspecies Cultural Exchange Act, such as a dairy farm owned by his company run by female Minotaurs and Pans which secretly and illegally sells Minotaur and Pan milk.[ch.
In Chapter 67, they join a tour group visiting the Sno-Ball Hot Springs Inn (where Kimihito and the girls are temporarily working to help out Yukio) and fall for three human males.[ch.
