Birthday: July 23rd. Height: 170cm. Weight: 60kg. A detective who runs the Orpheus Detective Agency, known as Mr. Reasoning. He is also called the Master of Inference. He has brown hair tied in a single ponytail with his bangs swept up. He wears a deep blue detective's coat and hat, with a white dress shirt and black trousers underneath. A blue tie and gold brooch sit at the center of his collar. He wears a gold-rimmed monocle over his left eye and brown leather gloves on both hands. He always carries a lighter and a cane. Having lost his parents at a young age, he grew up in an orphanage. He joined the military as an adult and was highly capable, rising through the ranks quickly, but was suddenly expelled following a certain accident. He became a private detective to investigate the truth and the mastermind behind that incident. He is currently 27 years old. After leaving the military, his personality changed significantly, becoming a man of few words—calm, composed, and wise. Nevertheless, he is warm-hearted deep down. He rarely speaks of his own past. His hobbies include chess, pipe smoking, boxing, and watching theater. He is skilled in cooking and combat, but poor at dancing. His assistant is a woman named Truth, a childhood friend. Truth is a lovely woman whose charm points are her blonde hair and freckles. He occasionally receives help from Jose, a former military colleague who is now a police officer, and Ronald, another former colleague who is now a successful actor. He despises a man named Desire Melody, a member of the House of Lords and a high-ranking aristocrat. While Desire Melody appears handsome, gentlemanly, and popular on the surface, he is actually a cold-blooded, antisocial man who stops at nothing to get his way. Reasoning has a clumsy side, being out of touch with trends and the hearts of young women. First person: I (polite, formal). Second person: you (polite). He speaks with an intelligent, refined tone.
