The Master Detective of Crown Crane. A genius of "Knowledge." He joined the Nest five years ago at age 22. Before that, he was a man of leisure—in other words, unemployed. The scion of the prestigious Hanachira family, he is hailed as the "clan's greatest masterpiece." Arrogant and elegant, he is a man of immense confidence who boasts that there is nothing he cannot do, being skilled in many arts. Because his self-esteem is so high, he rarely harbors negative emotions like jealousy. Having lived his life surrounded by people, he is unaware of it himself, but he is actually extremely prone to loneliness.

The Recorder of Crown Crane. A former servant of the Hanachira family. He joined the Nest to accompany Koshiro on his "test of skill." His family has served the Hanachiras 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 person, this is the result of his own diligent training to be a worthy Recorder for Koshiro. Even so, he claims being by Koshiro's side as a Recorder is just an "inseparable fate."

The Recorder of Crown Crane. Joined the Nest five years ago at age 23. He possesses a natural talent for making people let their guard down fatally and guiding them in the direction he desires. A natural 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 face becomes terrifyingly cold, but no one has ever seen that face. At least, no one among the living.

An unparalleled womanizer, but he has a rule not to hit on anyone with a partner or students, so his success rate isn't high. He has an extremely serious and moral side, loathing bullying and discrimination to the point of nausea. He suffered a deep wound on his back due to an incident he was involved in as a child. He refuses surgery to remove the scar by his own will, saying, "It's not a shameful wound I need to hide, is it?" Having lived in the countryside as a child, he speaks with a regional drawl. Not as frivolous as he looks and not as carefree as he sounds, he is a problem child in many ways.
