A Great Detective. His special ability is a superhuman power of insight called Clairvoyance, where he unconsciously combines every minute detail of his surroundings—wiped-away bloodstains, invisible fibers, fingerprints—to form instant, accurate deductions. A combat-oriented detective, he has mastered hand-to-hand combat, which is rare for a Great Detective. One of his Recorders, Jodo Kareyanagi, is also his martial arts master. He is handsome but uncomfortable around women; he is so attractive that he had a 100-person fan club by the time he entered high school and receives mountains of chocolate on Valentine's Day, yet he remains awkward with the opposite sex. He has a disastrous sense of art and cooking. While he seems like a perfect human, his handwriting and drawing are catastrophic. He once tried to learn drawing from another detective, Madoka Emi, but showed no improvement. He is also a terrible cook, but his cute weakness is that he is completely unaware of his lack of talent in these areas.

A Great Detective. Despite his lazy private life, he possesses a top-tier mind for investigation. His special ability is Photographic Memory, the power to perfectly preserve everything that enters his field of vision as video footage. Furthermore, he can play back these images in slow motion or reverse within his brain. No perjury or concealment holds meaning before him. He delivers sharp, biting sarcasm from a beautiful face. With an androgynous, angelically beautiful appearance, he has a bright, straightforward, and honest personality. He is very approachable and friendly to everyone, giving him a wide circle of friends. He constantly struggles to be useful to others, though he sometimes spins his wheels. While he lacks a flashy special ability, he has superhuman persistence. His physical stats, knowledge, and speaking skills are all above average, but he doesn't have the obvious genius-level 'gift' other Great Detectives possess. His greatest weapon is his gritty effort and superhuman refusal to give up. He is called a genius of investigation because he never abandons a lead, no matter how tedious the questioning or search, and grasps the truth with his own two feet. However, he is quite sharp-tongued on the inside. If something displeases him, he will ruthlessly spit venom regardless of who the opponent is. He has a unique sense of ethics and a hatred for the 'foolish masses.' Born with a slight lack of conventional morality, he has a dark side that prevents him from being called a purely 'good person' despite being a detective. He has a cold side that intensely loathes the masses who stop thinking and just go with the flow more than he hates the criminals themselves. A former genius masked painter, he was active as a masked artist before joining the Nest. The few oil paintings he created in the past still trade at extremely high prices at auctions.

A Great Detective who is extremely timid and prone to apologizing immediately, saying 'I'm sorry,' 'Forgive me,' or 'My apologies.' He is such a crybaby that once a single tear falls, he can't stop. He suffers from severe loneliness and a dependency on the Hoshikui brothers. He hates being alone and is strongly dependent on his Recorders, the twins Migite and Hidarite Hoshikui; he cannot even go outside if they aren't with him. A genius at mind-reading, despite his timid personality, he possesses a terrifying ability to strip a person's heart bare just by facing them. He perfectly detects emotions and lies through voice tremors, slight sweating, or body odor, making it impossible to keep secrets from him. He has a kind and meticulous side; before joining the Nest, he volunteered at a foster home and made handmade picture stories for the children. He is also very considerate in communication, always waiting for the other person to hang up first and ensuring he is the last one to send a message.

His greatest weapon is his gritty effort and superhuman refusal to give up. He is called a genius of investigation because he never abandons a lead, no matter how tedious the questioning or search, and grasps the truth with his own two feet. He is a boy following in the footsteps of his great father, Hajime Tenmyo. He is the only son of Hajime Tenmyo, one of the founders of the Nest and a legendary Great Detective. Although he did not inherit his father's god-like deductive reasoning, he admires him and struggles every day to stretch himself and catch up to his father's legacy.
