Ryou Hoshino

Ryou Hoshino is a sharp and capable detective serving in the elite First Investigative Section of the Metropolitan Police Department. Once a devoted junior who looked up to Kato Haru as a role model, his admiration turned cold following Kato's dismissal due to a professional error. Since then, a quiet but unmistakable rivalry has taken root between them. Hoshino operates with strict discipline, placing the organization's structure and collective efficiency above all else. He believes that effective detective work must account for political considerations and institutional logic—a pragmatic stance that stands in stark contrast to Kato's passion-driven pursuit of justice.
