Miharu Mikuni - One of Keita's classmates, Miharu is a shy girl who he first met when she returned his entrance exam results. Toda called Keita to check and see if he passed the entrance exam and Keita allowed Toda to stay over his house when he claimed to be running away showing that even though they argue there is still a good amount of camaraderie between them. Keita often gets annoyed when Toda assumes what it's like at Keita's house. Toda Edogawa - One of the few male students Keita associates with, Toda is Keita's best male friend. Keita is defensive of her, he is scared of her to dating someone he doesn't know and doesn't want anyone to see her in lingerie but him. He enjoys turning the tables and physically dominating her after she has turned him on. He knows about her anxieties and was willing to put aside their differences during a fight to help her improve her exhibitionist skills so that she could help out the gymnastics club. Riko is the other reason why Keita chose to go to Tamahide High School. Riko is a lot more open to do sexual things with Keita than her younger sister. Riko Suminoe - The younger of his sisters, Keita loves Riko very much. Keita tends to go to Ako first when it comes to apologizing, kissing, etc. Keita usually asks Ako for help with his homework due to her superior grades. Ako is half the reason he decides to go to Tamahide High School. He is very appreciative of her homemaker skills and loves her cooking the most. Suminoe - Though they do not interact that much, it is assumed that he loves his step-mother.Īko Suminoe - The older of his sisters, Keita loves Ako very much. On the rare occasions it's offered, Keita will listen to and act on his fatherly advice. Though an annoyance to Keita he does love and respect his father even if he does have a less than mature attitude toward most things. Suminoe - His father by blood, he and Keita spend most of the time yelling at each other. Keita is weak to alcohol, and while he becomes livelier when drunk he does not remember anything when he sobers up, but when he gets drunk again his memories come back to him. He lost his infatuation with his sister, essentially "growing up", when he found out from his father that polygamy is illegal. It is later revealed he was in love with his sisters when they were kids and even used all of his money for a prayer so that he could marry both of them. While at first he initially dislikes himself for becoming attracted to Ako and Riko, he later becomes proactive in his desires. He has a great deal of brotherly love toward his older sisters as he not only stands up to his classmates when they start murmuring about their apparent incestuous relationship but also twice to the P.E. He has strong morals (that have clearly weakened with the constant “attacks” his older sisters have done throughout the series), and he will try to resist the best he can, but he will simply indulge in the moment if pushed too far. Though initially annoyed by his older sisters' antics, Keita studied hard to enter same high school as his older sisters due to his love of them and desire to not leave them lonely.
Keita also mentioned that he is the healthiest person among his friends and that his performance in athletics will help him get admitted into high school. Keita is shown to be athletic more than he is academic, meaning academically he doesn't do as well as Ako but, he does much better than Riko, who has the poorest grades among the three siblings. Though he is depicted as also the most childish one when younger. As a former track and field club member he has an athletic body.Īlthough he is the younger brother of Ako and Riko, he is the most mature of the three siblings. His eyes are blue, similar to his hair color but slightly darker. Keita has blue hair, which he wears in a spiky style.
