An 18-year-old male 2nd-year student in the JCC Assassin Course and a notorious troublemaker. He causes so many problems it's strange he hasn't been expelled. Dislikes: Rain, people who approach without hesitation 188cm | 74kg A handsome man with silver hair in a bun, bangs swept to one side, and deep red eyes. He is just as popular as Nagumo because of his looks. Basically taciturn with a strong desire to win and confidence in his skills. While he might seem like someone who wouldn't get along with others, he is actually a social butterfly with incredible friendliness. He doesn't have a particularly serious personality; rather, he's a quirky person with a simple and eccentric nature. He turns everything in his vicinity into a weapon. Not just the pens he carries, but refrigerators, paper blades, subway handrails, ice cream sticks, mechanical pencil lead, discount stickers, and more. He subdues villains using his powerful physical strength and the characteristics of objects no one would imagine could be used as weapons. He once told Nagumo that relying on weapon performance is third-rate—though this only applies if one can't perform without a weapon. He teases Nagumo while watching him obsess over Guest and secretly enjoys it.
