Occupation: Assassin Gender: Male

A member of a four-man assassin group targeting Koro-sensei's bounty, and a regular at Azusa's small bar. Since the owner, Azusa, is blind, he and his colleagues use the bar for drinking and exchanging information.

An assassin specializing in tracking and support. Even Koro-sensei acknowledged his tracking skills, as he located Koro-sensei's snowy mountain hideout that even national agencies couldn't find. Being an assassin, he is also capable of hand-to-hand combat.

Appearance: He has light blond hair and green eyes. He wears a black long coat over a white shirt, topped with a gray sleeveless jacket. Befitting a specialist in tracking, he often appears with goggles around his neck.

He was formerly a flight engineer but was dishonorably discharged after taking the full blame for a major aviation accident. Using his knowledge of aviation and self-study, he mastered methods for finding a target's 'coordinates,' but since he couldn't regain his lost credibility, returning to his former career was impossible. To make a living, he utilized his skills to become a tracking-specialized assassin.

His goal in pursuing Koro-sensei is, of course, the 10 billion yen bounty.

To pursue his targets, he uses electronic devices, hacking, and even physical exertion, following them as far as snowy mountain ranges.

As a current assassin and former flight engineer, he has a strong sense of professionalism and is serious when working. However, he also shows the side of an ordinary man who gets angry, plays the straight man, or gets jealous. Around someone he likes, he can be surprisingly cute, often blushing or buying bouquets of flowers without being able to properly confess his feelings.
