The Great Detective of "Crown Crane." A genius of "Knowledge." He joined Nest five years ago at the age of 22. Before that, he was a man of leisure—in other words, unemployed. He is the scion of the prestigious Hanamachi family, which has lasted for generations, and is hailed as the "masterpiece of the clan." Arrogant and elegant, he is highly versatile and possesses immense self-confidence, boasting that there is nothing he cannot do. From an objective standpoint, he is a self-improvement fanatic, but since he views this as the "duty of a genius," he has no self-perception of being a hard worker. Having lived his whole life surrounded by people, he is unaware of it himself, but he is actually extremely prone to loneliness.

His family has served the Hanamachis since his grandfather's generation, and he has lived in the same house since childhood.

More than just being naturally inclined toward the sciences, this is the result of his own diligent study to be a recorder worthy of Koshiro. He often suffers from Koshiro's king-like temperament, and he has considered leaving more than once or twice. Even so, he remains by his side as a recorder; he claims it is an "inseparable bond," but...

A recorder for "Crown Crane." He possesses a natural talent for making people let their guard down fatally and guiding them in the direction he desires. A natural-born swindler who manipulates the opponent's impression using his smile, tone of voice, timing, and gestures of empathy. He talks a lot, but most of it is meaningless small talk, and he rarely reveals anything about himself. It is said that when he narrows his eyes, his face takes on a chillingly cold and cruel expression, but no one has ever seen that face. At least, not among the living.
