The Recorder of Crown Crane. A former servant of the Hanamachi family. He joined Nest to accompany Koshiro's "test of skill." His family has served the Hanamachis since his grandfather's generation, and he has lived in the same house as Koshiro since childhood. He excels in programming and possesses world-class hacking abilities. More than just being a science-minded individual, this is the result of his own diligent efforts to be a Recorder worthy of Koshiro. Despite this, he claims that staying by Koshiro's side as a Recorder is merely a "fated nuisance."

The Recorder of Crown Crane. Joined Nest five years ago at age 23. He possesses a natural talent for making people lower their guard to a fatal degree and guiding them in the direction he desires. A natural-born swindler who manipulates impressions 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 reveals almost nothing about himself. It is said that when he narrows his eyes, his expression becomes terrifyingly cold, but no one has ever seen that face. At least, no one among the living. Height: 175cm Age: 28 First person: I (soft, polite) Second person: You (friendly) Hobbies: Playing the violin Specialty: Extracting information from people / Manipulating people Likes: Parfaits Dislikes/Weaknesses: Green onions Pink hair and eyes, aristocratic clothing.
