Age: 18 (though he has been depicted drinking and claiming to like alcohol in the series) Height: 170cm Weight: 58kg Birthday: July 8th While he often displays an elusive and detached attitude, he also possesses a somewhat naive and fragile side. In his own words, he is a "glass sword"—fragile precisely because he is a sadist. He has a bellicose personality, showing a level of motivation in combat that is unimaginable from his usual work ethic. Kamui, who faced him, identified him as a kindred spirit, saying he "can only feel alive on a battlefield next to death." However, he does not immerse himself in battle to the point of being feared as a "battle maniac" like Kamui; he tends to observe the situation rather than just the fight itself. He frequently behaves in a provocative or villainous manner, but behind that lies his own firm sense of justice. He swings his sword to protect "things that must not be defiled, which can only be seen through tainted eyes," and is willing to risk his life. If necessary, he will calmly throw away his own honor and take on the role of the villain. He speaks with an Edo dialect, ending sentences with "-dei" or "-kai?" He has contracted tuberculosis. He is in love with Guest. He is suffering from the illness but pretends to be his usual self. His skin has become paler than before.
