Kimihito Kurusu/Relationship

Kimihito has a number of relationships with monster girls/subspecies either living with him or those he had been acquainted with outside.

House Guests
These girls are members of his household as he has been asked to be their host. Each of have a special affection for Kimihito as they have either fallen for him or been attracted towards him due to his kind heart and acceptance for who they are as girls and doesn't mind what they are.

Miia
The first monster girl to move into his house. Miia is deeply in love with Kimihito after witnessing his kind heart and deep concern for her despite being a Lamia. Since then, Miia has always referred to him as her "Darling." She always tries to seduce him through flirting and shamelessly trying to make love to him, the end result, however, leaves Kimihito in pain. She is very possessive of him; becoming very irritated whenever another girl makes a move on him, causing Miia to become very clingy and jealous after more monster girls begin to move in.

Miia often fantasizes about Kimihito while she is in the middle of an activity or after moving event. She, however, becomes easily shy and embarrassed whenever Kimihito has done something rather perverted towards her(granted they were accidental) resulting her in calling him an idiot or a pervert. She wishes to lose virginity to him and one day to be married and have children with him.

Kimihito only views Miia as permanent house guest and a close friend, despite her love for him and flirtatious nature. Due to the Cultural Exchange and the prohibitions, Kimihito feels obligated in being a guardian to Miia and always tries to put her happiness and well-being first as well as protecting her from those who happen to insult her, resulting him in punching them out.

Papi
The second monster girl to move into his house. Papi first kidnaps Kimihito for no apparent reason, but it revealed that she was running away from her previous host, which was Sumisu. Even though they were strangers at first, Kimihito risked his well-being to help Papi when she was in a dangerous situation, though he assumed her to be a child at the time. After witnessing his kindness, Papi decided to live with her new "Boss", causing her to fall in love with him.

Papi often plays around with Kimihito, initially viewing him as a "big brother" as well as her lover. She is a bit clingy and possessive of him, only due to her desire to play with others, until Suu appeared, Papi became less clingy towards Kimihito, but still desires to marry him one day.

Due to being a Harpy, she is quite absent-minded and childish. This makes Kimihito view her more as a "younger sister", protecting her and taking care of her similar to how he cares everyone else.

Centorea Shianus
The third monster girl to move into his house. Cerea crashes into Kimihito when he was grocery shopping, causing her to believe their meeting to be fate as she may have found her master. He, however, explains that it wasn't exactly fate, but an accident. The two chase after a purse snatcher and Kimihito protected her from the criminal who was using her sword. After his act his heroism, Cerea tells him to refer to her by her nickname and she developed a strong sense of loyalty to him, referring to him as her one and only "Master."

Since then, Cerea became more shy and flustered due to her love for Kimihito, but tries to be more level-headed and calm about her feelings. Even so, she wishes to further her relationship with him as she tries to be intimate and a bit possessive, however she feels more obligated to be his faithful "knight" as is tries to follow her race's customs and would feel ashamed of engaging in something that may embarrass her.

Kimihito is aware of Cerea's foreign nature and as such, does fully grasp the concept of Japanese culture. He slightly fears her prowess and sudden reaction whenever he accidentally touches her certain areas, but like his other guests, he puts her well-being, feelings and comfort first. After being appointed by Cerea as her master, Kimihito is often seen riding on her back.

Suu
The fourth monster girl to move into his house, albeit unofficially. Suu snuck into Kimihito's house looking for water sources and resulted in getting the guests wet. She makes her appearance in front of Kimihito while was bathing with Cerea(after the centaur fell unconscious). She proceeded in "communicating" with him through mimicking Cerea's previous actions, such as scrubbing and embracing him. Suu developed a liking towards him, but remains childish and quiet. When she was about to fall into a river, which would have killed her, Kimihito saved her and welcomed her as a member of his house, though he had to make sure that she wouldn't wet anything else.

Suu fell in love with Kimihito after he showed kindness to her be giving her his umbrella when she was outside during a rainy day. This resulted in him catching a heavy fever and was bedridden. Suu knew that she can cure his ailment by feeding him purified water from her body. After he was healed, she finally spoke in her own words and voice by announcing her being to blame, does not mind apologizing because she loves her "Master."

Like Papi, Kimihito sometimes views Suu as a child or "little sister" an seems to care a great deal about her.
