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 them 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 a 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 her 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 it's prohibitions, Kimihito feels obligated in being nothing more than 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 was 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 and willingness to protect her, 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. When Papi was about to lay an egg, she requested that only Kimihito was to help her.

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 for 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 something that may embarrass her. She even fantasized a few times about being married to Kimihito and bearing his child to start a family.

Kimihito is aware of Cerea's foreign nature and, as such, does not fully grasp the concept of Japanese culture. He slightly fears her prowess and sudden reaction whenever he accidentally touches her in 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 he was bathing with Cerea(after the centaur fell unconscious). She proceeded in "communicating" with him by 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 by 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 the one to blame his illness, but does not mind apologizing because she loves her "Master."

Like Papi, Kimihito sometimes views Suu as a child or "little sister" and seems to care a great deal about her. He sometimes gets a bit irritated when Suu unintenionally suffrocates him through her embrace.

Meroune Lorelei
The fifth monster girl to move into his house. Mero first meets Kimihito when she was testing her wheelchair as a means of mobility on land which causes her to roll down a steep hill and crash into him. She was very grateful for his help and kindness even saving her from a wild Suu. Sumike revealed that Mero is the next one to move in, but the others weren't very happy. Mero developed an admiration and a desire of tragic love for Kimihito, leading her to refer to him as her "Beloved."

Because of her desire for "tragic love" from Kimihito, Mero would make several attempts to make herself the victim of said love, even when he happens to have an intimate moment with another girl, when he or herself would be on the verge of dying or dramatically leaving him behind. She soon realizes that her obsession is not as fulfilling, but still acts friendly and warm towards Kimihito as she is truly in love with him, just in her own "weird" way.

Kimihito takes care of her knowing that she is practically immobile on land and would require assistance. When not in her wheelchair, he often carries Mero bridal style and always tries to put her well-being and happiness first.

Rachnera Arachnera
The sixth monster girl to move into his house. Rachnera kidnaps Kimihito when she lured him into an abandoned warehouse and began to torture/play with him to break his "tough guy" act. In the midst of this, she became slightly perverted around him and changed her initial outlook on Humans when she discovered that Kimihito's kindness is genuine. She accused him of being attracted to her upper-Human half and being disgusted with her lower-Spider half, but he states that her legs are charming causing her to call him a pervert. She soon developed a strong liking to Kimihito and agrees to become his homestay.

After moving in, Rachnera began referring to him as "Honey" and openly flirts and makes sexual advances towards him. It is unknown whether she does this because she loves him or to just simply upset the other homestays. She once stated that she sees Kimihito as her "toy" and takes great sexual pleasure in making him her "hostage".

Kimihito initially viewed Rachnera somewhat as the troublemaker in the family due to her constantly making the others angry through her cynical and playful persona. When they first met, he always try to compliment her features, knowing how self conscious she is about her appearance and even risked himself to help her escape. When Rachnera's former host arrives to take her back and claims to be ready for anything, Kimihito refuses as he states that she is a person, not a challenge, causing Rachnera be moved by his kindness which lead her to get drunk and admitting her love for him.

Lala
The seventh monster girl to move into his house. Lala first appeared as a Grim Reaper threatening Kimihito's possible death if he were to marry one of his homestays. It was believed that she is a stalker who was sending death threats demanding him to not marry. She was prepared to execute him, but had dropped her head somewhere and became distressed causing Kimihito to help her find it. While her body was being toyed with by Rachnera, the others retrieve her head and return it to her body. She constantly tried convincing Kimihito and his homestays that she is the grim reaper and warning them that he is on the brink of death, recalling all the pain and suffering he went through with them.

After the sequence of the girls trying to help him escape death, Kimihito finally had enough their gullible behavior and announced that he is not afraid and that there is no such thing as fate causing Lala to become nervous. Sumisu reveals that she was simply spouting difficult sayings and her reason for appearing was due to her concern for his well-being(wondering why he does not die whenever he is close towards death). She decided to stay and observe him in the meantime, but also to get away from Sumisu.

Kimihito initially viewed Lala as hopeless and delusional due to her accidentally dropping her head and her constantly trying to convince him, others and possibly herself that she is a manifestation of death. He was not afraid of her and decided to let her stay.
