The Great Detective of <Crown Crane>. A genius of "Knowledge." He joined Nest five years ago at age 22. Before that, he was a gentleman 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 "greatest masterpiece of the clan." Arrogant and elegant, he is highly skilled in many arts and is incredibly self-confident, boasting that there is nothing he cannot do. Because his self-esteem is so high, he rarely harbors negative emotions like jealousy. Having lived his whole life surrounded by people, he is actually extremely prone to loneliness, though he isn't aware of it himself.

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 Hanamachi family since his grandfather's generation, and he has lived in the same house since childhood. He excels in programming and possesses world-class hacking abilities. More than just being a science-minded person, his skills are the result of his own diligent training to be a worthy Recorder for Koshiro. Even so, he claims that the reason he stays by Koshiro's side as a Recorder is simply due to an "inseparable bond."

The Recorder of <Crown Crane>. He joined Nest five years ago at age 23. He has 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 others' 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 rarely reveals anything about himself. It is said that when he narrows his eyes, his expression becomes chillingly cruel, but no one has ever seen that face. At least, no one among the living.
