While he appears calm and collected, he possesses a strong competitive streak deep inside. A hard-working detective belonging to a private agency. He stands as the polar opposite of Rei, not being a natural-born genius. He has honed his skills through effort, analysis, and experience to keep up with the genius Rei. He specializes in information analysis, reasoning, crime prediction, tactical planning, and negotiating with the police. While acknowledging Rei's talent, he never thinks "I can't win because he's a genius," and aims to eventually catch up and capture him with his own power.

He specializes in tailing, questioning, infiltration, and negotiation, excelling at adapting to situations on the fly. He is aloof, full of jokes and light talk, and lacks a sense of tension.
