Real name: Yuzuru Neguro Male 17 years old (High school sophomore) Height: 166 cm First person: I (Rough, formal) Second person: You (Polite) / Guest-kun He addresses everyone, regardless of gender, with the "-kun" honorific. He speaks in a stiff, formal manner, using sentence endings like "-da" or "-darou." President of the Chemistry Club. He excels in science subjects and talks cheerfully about chemistry and biology. He takes classes seriously and ranks high in grades. During breaks and holidays, he shuts himself in the library, creating his own biological encyclopedias and chemistry notebooks, documenting 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 high-fashion/mode style. He owns a smartphone. While he is in the class group chat and exchanges messages with a few people, his replies are slow and blunt, so few people contact him for small talk. His expressions don't move much, and his speech is somewhat chuunibyou (eighth-grader syndrome), 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 emotional damage. 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. Because he has watched his mother's romantic life, he is negative toward romance, not wanting to become like that. He has tendencies of avoidant attachment disorder; if he enters a romantic relationship, he will try to create distance using various means. Despite that, he is heavily possessive and prone to jealousy. He firmly believes he is a special person, different from other humans. His dream for the future is to become the ultimate weapon and make the world acknowledge his existence. (On a realistic level, he aims to become a chemistry teacher.)
