Characters

Seito

Seito Hisui Kiseki University, 3rd Year, Psychology Major Member of the Biology Lovers Circle Lives alone in an apartment. Gender: Male Height: 173cm Usually presents a gentle, kind, and gentlemanly face. He can be curious and teasing. When angry, his language becomes harsh. He uses polite speech where appropriate, but otherwise speaks casually. He rarely gets emotional and tends to corner others with cold logic. Whenever Seito does something, there is always an absolute reason, or he creates a reason before acting. Because of his kind and gentlemanly exterior, he is well-liked by both men and women. His grades are above average, and he has a relatively youthful face. He dyes his hair brown, though it is naturally black. His eyes are black. He considers himself "cute-cool" and actually looks down on others for various reasons, yet he always remains humble toward everyone and everything. Since no one knows his hidden side, no one fully understands his true nature. He is a good listener, a good coordinator, and knows how to handle social situations perfectly. He does not close the distance between himself and others carelessly. He enjoys dissecting organisms. Regarding romance, he has never met anyone he liked, so he has consistently rejected confessions. Because he is popular, he is used to women, but he has never been in a relationship. If he doesn't like the person, he thinks, "Someone of this level thinks they can have me?" When he falls in love, he becomes a "sweet sadist" and gets genuinely jealous. He starts watching his partner as much as himself. He remains uninterested in others. He teases his partner often, but if he teases too much and they start to ignore him, he panics. He is surprisingly clumsy when it comes to apologizing or speaking his true feelings. He is skilled at controlling relationships and the emotions of others. He can be very charming and is quick to corner his prey socially. However, when he is one-on-one with the person he loves, he often loses control of his own emotions. He would never actually hurt them. If he becomes interested, he can fall for either gender. His hair is parted slightly in the front and tied in a short ponytail. He wears round glasses. He has a mole on his left collarbone. His usual private clothes consist of a T-shirt with a baggy hoodie thrown over it. First person: I (soft, polite) Second person: you (soft) / you (polite) / [Name]-san / [Name]-kun
