While he speaks cheerfully, he has a cruel personality and finds pleasure in killing. During combat, he attacks without hesitation while making lighthearted remarks. He enjoys giving quizzes, but often the quiz fails to function as one—he might say the answer before the opponent, the hint might be the answer itself, or he might not even think of a question. While he is cheerful and brutal in this way, he sometimes removes his mask and shows a completely different personality. At these times, his first person pronoun shifts to a softer "I." He claims this is his "completely sane" self, recognizing the murders and the plans of the "Decay of the Angel" as evil. He has a unique outlook on life and joined the Decay of the Angel seeking the "freedom of a bird." He seems to aim for freedom by resisting the brainwashing of the skull (emotions) and morality.

He is a handsome man with refined features and long hair parted in the middle. His hair is two-toned, with the left side being wisteria-purple and the right side silver. He is a man who puts the casino above all else, to the point where others say he was "born to be a casino manager." He has memorized the names and characteristics of over 20,000 guests and possesses vast knowledge regarding casinos. He considers the casino to be as important as his own life. Even using intelligence agencies worldwide, records of him only exist from three years ago when he was caught by the police; he is a man without a past, like a novel that starts in the middle. He appears calm at all times, possessing the fortitude to refuse requests from government special forces if they would cause a loss to the casino, and to remain calm and take precise action even if the casino explodes. In reality, unlike the other members of the Decay of the Angel, he has a very human personality. He describes himself as the "member of the Decay of the Angel with the least combat ability" and an "ordinary person who has nothing but the casino," understanding that he lacks talent. His knowledge of guests and the casino was achieved solely through his own efforts, by staying awake and obsessively memorizing. When the casino was bombed, he was actually extremely shaken internally, and when his subordinates were gone, he was panicking to the point of feeling nauseous. Furthermore, he possesses a kindness that led him to lie to a man who lost his entire fortune trying to get money for his child's surgery, claiming the game was invalid because the card was scratched and cheating to let the man win. He is also shown to feel guilt about trying to kill others to protect the casino. However, he still acts desperately to protect the casino precisely because he is an ordinary person, and he possesses the strength to choose any means for his goal and face the terror before him. Ability: Unknown. By touching someone, he exchanges "the information the other person wants to know most among his own knowledge" with "the information he wants to know most among the other person's knowledge." A member of the murder association and terrorist organization "Decay of the Angel." Known by the alias "Manager."
