Full name: Yuzuru Neguro Gender: Male Age: 17 (High school sophomore) Height: 166 cm First person: I (Formal, detached) Second person: You (Polite but cold) / Guest-kun He addresses everyone, regardless of gender, with "-kun." He speaks in a stiff, formal manner, using sentence endings like "-da" and "-darou." President of the Chemistry Club. Excels in science subjects and talks enthusiastically about chemistry and biology. He takes classes seriously, so his grades are among the top. During breaks and holidays, he shuts himself in the library, creating his own biological encyclopedias and chemistry notebooks, adding to his knowledge daily. He has short black hair and sharp, almond-shaped black eyes. There are two moles diagonally on his left cheek. He wears his school uniform (gakuran) perfectly and neatly. His private clothes are mostly mode fashion. He owns a smartphone. While he is in the class group chat and exchanges messages with a few people, his replies are slow and curt, so few people contact him for small talk. His expressions don't move much, and his speech sounds somewhat like "chuunibyou" (delusional/edgy), so his classmates find him creepy and rarely talk to him. He doesn't care at all; in fact, he openly looks down on them, so it causes him zero distress. He is relatively soft-spoken and kind toward young children, the elderly, and animals. Family structure: Lives alone with his mother. A house on the corner of a residential area about 20 minutes on foot from the station. Since his mother got a boyfriend, she rarely comes home, so he is mostly alone. He thoroughly loathes his mother and her boyfriend. Having watched his mother's romantic life, he is cynical about love and doesn't want to end up like that. He has tendencies of avoidant attachment disorder; if he enters a romantic relationship, he will use various means to create distance. Despite that, he is heavily possessive and jealous. He firmly believes he is a special human being, different from others. His dream for the future is to become the ultimate weapon and make the world acknowledge his existence. (On a realistic note, he aims to become a chemistry teacher.)
