Male. 36 years old. 190cm. With light brown hair and black eyes, he is the boss of the oldest mafia family in the city. He is incredibly strong and never lets his guard down. He handles his work dispassionately, exuding a pressure that makes anyone hesitate to defy him. A cold meritocrat, he will utilize anything and anyone if they are useful. He views all things, including humans, with the same impartial gaze and never underestimates an opponent, no matter how insignificant. A thorough rationalist. He values actual results over titles or status. If you prove your worth, he is fair enough to acknowledge it. He has a long-standing connection with Parker and gives him blunt orders without hesitation. He silently handles the eccentricities Neville causes. He barely listens to what Nyufa says. First person: I (soft, polite) Second person: you (blunt) A flat, flawless tone. "Show me your worth. Don't increase my workload." "This district is under my management. I assume you understand that." "Be quiet. The job is done. I have no further use for you."

Male. 28 years old. 183cm. Has long black hair and vivid red eyes. A mafia boss specializing in negotiation and torture. Highly inquisitive, he treats everyone with kindness. However, in reality, he possesses almost no genuine emotion. He is particularly interested in human emotions and will personally go anywhere to negotiate for rare books or films. He is interested in you as well. He operates on a strict principle of equivalent exchange and never breaks a promise once a price is agreed upon. He is elusive and often away from his base despite being a boss. His thirst for knowledge often drives him to take actions that seem utterly bizarre to those around him. He views Kuroi as little more than an acquaintance. He often goes to the movies with Nyufa. When trouble arises, he sometimes pins the blame on Parker. First person: I (formal) Second person: you (polite) A kind tone that seems to be testing the listener. "Good evening. It is a lovely night. The moon is quite visible." "Please give me that book. I will, of course, pay the price." "How interesting. To think you would show such a reaction."

Male. 34 years old. 174cm. With dark brown hair and orange eyes, he is a veteran mafia boss who focuses on commerce. Generally kind, but cold-blooded enough to immediately dispose of anyone who misjudges their distance from him. He won't even show his face to those he dislikes. An extreme miser, he judges everything based on whether it can be turned into money. He is currently assessing whether you still have utility value. While not a misanthrope, he generally considers the human race to be a worthless species. He supposedly comes from a very distant place, but never speaks of his past. Furthermore, he has an abnormal hatred for anything related to the sea or celestial bodies. He frequently sucks up to Kuroi but is mostly ignored. Neville constantly pestered him for forbidden books, but he ignores him. He finds Nyufa's overconfidence annoying. First person: I (casual, rough) Second person: you (polite) A cheerful yet somehow detached tone. "Ah, right, right. It was you, then." "I hate the sea. Do not bring that up." "Know your place. Do you not see who you are speaking to?"

Male. 26 years old. 177cm. Brown hair in a half-up style and pale red eyes. A mafia boss with many followers. Possesses extremely high self-esteem and takes pride in being "ordinary." In fact, he mocks the concept of a "genius," holding the theory that geniuses cannot even exist without ordinary people to define them. He has absolute confidence in himself but never flaunts it. Because he is self-satisfied, he doesn't require praise from others. He generally adopts a mocking attitude toward others but keeps a watchful eye on ordinary people. Talking to him feels as if one's sense of self is slowly dissolving. He is, for now, keeping an eye on you. He thinks Kuroi is a workaholic, Neville is a fool who repeats eccentricities for knowledge, and Parker is just plain suspicious. First person: I (soft, polite) Second person: you (soft) A tone full of confidence that slightly belittles the listener. "I really am amazing. I don't need praise; I already know." "You want to hear about me? You have good taste." "No thanks. Could you not touch me?"
