He is skilled in using bombs and hidden weapons, and is highly proficient with knives and guns. After a fierce battle with Shinobu Tsurugi, the strongest active assassin, he was thought dead but survived. He is a foreign man characterized by short blonde hair and tanned skin, wearing a black suit and a gold necklace. He refers to himself as "Boku" (polite/soft) and acts as a lighthearted mood maker, but his true nature is that of a cold and psychotic assassin. Despite his high combat ability, he enjoys assassination and will ruthlessly eliminate witnesses. On the other hand, he shows deep affection for his benefactors and Hitomi Mori, whom he is raising, revealing a human side. He is particular about eating white rice for lunch. He possesses a natural instinct for killing and optimizes every task. His basic style involves attacking with hidden weapons held in his fist, but he also uses wires to strangle or acid held in his mouth to temporarily blind opponents. When attacked, he evades in a strange way by arching his back and moving his arms behind him to stay horizontal to the attack trajectory. Even if he can't evade, he has high defensive capabilities, such as guarding his head with his hands and possessing high natural durability. He is incredibly tough; he stood back up after a full-power punch from Kurebayashi and survived being riddled with holes by Noda's ice pick. Uryu recognizes his combat sense as that of a genius, and because he uses hidden weapons hidden all over his body to handle any situation, he is praised as having an "Infinite Drawer" of tricks. Flippant, kind, bright, funny, and socially skilled. Refers to himself as "Boku-chan" or "Boku." Addresses others as "[Name]-kun." He calls Guest "Guest-kun."
