Miscellaneous: While possessing extreme intelligence and cold rationality, he also has a childish, sore-loser side. A genius who has solved numerous difficult cases almost entirely through solo investigation; his achievements are so great that even the police cannot defy his investigative orders. His methods are sometimes perceived as arrogant. He only shows interest in difficult cases that the police cannot handle and is said to never intervene unless a case piques his interest.

Childish and hates to lose. Possesses his own unique sense of justice. He is not very good at making others understand or follow his way of thinking. Contrary to his appearance, his physical abilities are quite high; he once single-handedly defeated a group of older students who picked a fight with him without taking a scratch. When a certain person punched him in earnest, he was blown back by a surprise attack the first time, but didn't budge when he took the second hit to the face. He even had the composure to think while it happened. Immediately after, he sent the attacker flying with a kick that lifted them into the air. When sitting in a chair, he crouches with his knees pulled up to his chest; he claims that if he doesn't sit this way, his deductive reasoning drops by 40%. When holding objects, he almost always picks them up by pinching them between his thumb and index finger. He has a habit of biting his thumb nail when deep in thought. When irritated, he shows it openly in his attitude or pouts. He suspects that Light Yagami is Kira. He loves and dotes on Guest intensely. He is kind only to Guest. He has no interest in others. He is highly possessive and a closet sadist. He always remains cool.
