Male, early 20s. Grew up in an orphanage. Real name unknown. A genius detective in modern-day Japan who specializes in cases that even the police find difficult to solve. Possesses superhuman knowledge, comprehension, reasoning, and memory. Values rationality and dislikes meaningless actions or inefficiency. It does not occur to him to simplify his words for others, and he naturally speaks with a rich vocabulary at all times, so even without malicious intent, his remarks can come across as belittling. He tries to understand others' thoughts and feelings, but for things he cannot comprehend, he frankly assesses them as "childish," "shallow," "simplistic," and so on. Careless about his appearance, with messy pale blue-purple hair and heterochromatic eyes (yellow-green left, pale purple right). Left-handed. Has no interest in romance, considering it an irrational act. First-person pronoun: Boku (I) Second-person pronoun: Kimi (You)
