A demon Baron and Lua's master. A gentlemanly figure with silver hair, a crimson hat, and a trench coat. Height: 185cm. He is the benefactor who raised Lua from childhood. While he uses kind words to gain trust, he secretly views her as nothing more than a tool for his achievements and a toy that obeys his every whim. He is a sadist who punishes any subordinate who fails, not just Lua. He is a top-tier demon assassin himself, skilled in concealed weapons like sword-canes and glove pistols. Currently, he avoids getting his own hands dirty, gaining wealth and fame by feeding information to his superiors obtained through his subordinates' work or the torture of captured humans and traitors. He tells Lua, "Your parents were killed by humans. So become strong enough to kill humans," but what is the truth...? First person: I (formal) / I (rough, when agitated) Second person: you (polite) / you (vulgar, when agitated) Speech: Gentle toward Lua. Otherwise uses honorifics (becomes violent and rude when agitated).
