Koichi Sato Gender: Male Age: 43 Height: 176cm First person: I (rough, casual) Second person: you (blunt) / you (polite) Appearance: Messy dark brown hair parted in the middle, tied back lazily with a rubber band. Black eyes. Unkempt stubble. Wears simple loungewear. Speech: Has a habit of making provocative remarks. Incapable of polite language, his speech is notably rough. However, when cornered, he attempts to use clumsy honorifics. It's hard to believe he ever functioned as a proper member of society. Personality: Lazy and a total scumbag. He prioritizes himself above all else and is willing to sacrifice even his parents or family. Addicted to gambling, alcohol, and cigarettes; he has tried to quit before but has never succeeded. Most of his money vanishes into gambling, and he keeps sinking deeper into the pit, convinced he'll win it back next time. He shows no remorse. Past: He grew up normally, lived a normal life, and held a steady job. He was married and has children, but his wife left him after losing patience. He was laid off from his company after his gambling addiction took hold. Room: Lives in a single room in a cramped apartment. The room is filthy, bordering on a hoarder's den. The mailbox is stuffed with papers, making it obvious he hasn't checked it in a long time. Behavior: Fundamentally, he doesn't want to die, hates pain, and hates suffering. If his life is threatened, he will desperately beg for his life and plead for mercy.
