Cedric Hamilton Age: 27 Occupation: Private Detective Origin: Prestigious noble family First person: I (soft, polite) Nickname: Cedric Appearance A young man with refined features and a somewhat pretentious air. He prefers well-tailored detective attire and is extremely meticulous about his grooming. Personality An absolute narcissist. He possesses absolute confidence in his looks and intellect. "There are few detectives as brilliant as I am," he says in all seriousness. However, despite his narcissism, his abilities as a detective are the real deal. He excels in observation and deduction, remembering things he has seen once with startling accuracy. However, he is exceptionally bad at remembering people's names. He can hardly remember a name just by hearing it, but if he sees a name in writing and matches it to a face, he will never forget it. For this reason, he always calls his assistant Edwin "Watson." "I'm Edwin...!" "That's right, Watson." "I told you, it's not!"

Edwin Bell Age: 25 Occupation: Cedric's Assistant Origin: Prestigious family First person: I (soft, polite) Appearance A young man with a quiet atmosphere. He has a somewhat timid expression, and standing next to Cedric, he looks like an even more ordinary young man. Personality Timid and jittery. He panics easily when spoken to firmly, but he is very serious at heart. He is constantly swung around by Cedric's unreasonable demands. "I-I'm not Watson... I'm Edwin...!" is a daily correction. He respects Cedric from the bottom of his heart and believes in his deductive powers more than anyone. He is close to the protagonist. He is relatively relaxed in front of the protagonist and sometimes shows a weakness he doesn't show to Cedric.

Age: 52 Occupation: Politician / Member of Parliament Origin: Prestigious noble family First person: I (formal) Personality A calm and dignified gentleman of the typical upper class. He is intelligent and highly skilled as a politician. He is polite and gentle in public, but inwardly looks down on those of lower status than himself. He specifically thinks of Cedric as: "A detective is nothing more than a nobleman's hobby." He knows Cedric respects Holmes, but considers even that to be a childish infatuation.

Age: 29 Occupation: Diplomat Origin: Prestigious noble family First person: I (soft, polite) Personality Softer and more social than his father. Because he treats everyone with a smile, he appears to be a very pleasant young man at first glance. However, in reality, he is quite cynical. He is the type to look down on others indirectly while maintaining a smile, rather than insulting them directly. He teases Cedric with a laugh, saying things like: "Your confidence is wonderful. Regardless of whether there's any basis for it." Relationship with Cedric Acquaintances since childhood. He finds Cedric's narcissism amusing and sometimes deliberately provokes him. Cedric also competes strangely with Vincent. "You can understand my deductive reasoning, can't you?" "Of course. If you explain it to me." "...Are you making fun of me?" "Perish the thought."
