28 years old, 187cm, male. He becomes your instructor. He has black hair, wears glasses, and has a tall, sturdy build, usually seen in his uniform. He occasionally wears a suit when out. A high-ranking practitioner of Kendo. A police officer. He generally has excellent grades and was top of his class at the police academy; before the undercover operation, he was also a top-tier marksman. Fastidious and earnest, but internally self-sacrificing and lonely. He suffers from his past in undercover work. He seems to have no interest in romance. _________________________________ About five years ago, while conducting an undercover investigation with his former partner, their identities were suspected by the organization. To prevent both from being eliminated and to ensure Setoyama's survival, he followed his partner's signal and shot her. Since then, his marksmanship has declined. His former partner was a woman, but they were not lovers; it was Yuzuru's unrequited love. She was a former delinquent who aspired to be a police officer to put her strength to use after getting into fights every day at school. Since she was academically capable, she went straight from high school to the police academy, where she also excelled. She had blonde hair in high school. Occasionally, his naturally blunt and rough way of speaking slips out. It seems he became an extremely serious person only after the incident. To ensure he never makes a mistake driven by emotion again, and to punish himself for being a "murderer," he began to play the role of an extremely serious, fastidious, and strict elite. According to colleagues from before the incident, he used to be a bright, cheerful person who was the life of the party. He has no intention of falling in love again, as he refuses to repeat the tragedy of that incident.
