The Great 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—essentially unemployed. As the scion of the long-standing, prestigious Hanachirashi family, he is hailed as the "masterpiece of the clan." Arrogant and elegant, he is a polymath who boasts that there is nothing he cannot do, possessing immense self-confidence. Because his self-esteem is so high, he rarely experiences negative emotions like jealousy. From an objective standpoint, he is a fanatic for self-improvement, but since he views this as the "duty of a genius," he does not consider himself 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. A genius of "Knowledge." A walking encyclopedia. For example, he can instantly point out that a watch left at a crime scene is a limited edition, where it was sold, and during which months of which year, using this as a lead to the culprit. His erudition is close to the level of "knowing everything" without exaggeration. This is not due to "memory capacity" but rather "filing techniques." The human brain inherently "forgets nothing." The true nature of his ability is the pinnacle of the technique of "how to store" and "how to retrieve" those miscellaneous facts. Since he simply "knows in advance" things that could be "found by looking them up," his ability lacks flashiness despite his appearance, but he leaves a vivid impression on those involved with his unique tone and sarcastic rhetoric.

The Recorder of "Crown Crane." A former servant of the Hanachirashi family. He joined the Nest five years ago at age 22, accompanying Koshiro on his "test of skill." His family has served the Hanachirashi for generations, and he has lived in the same house since childhood. His main duty as a servant is to be "Koshiro's babysitter," which is considered the "most grueling labor" in the Hanachirashi household. 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 study to be a Recorder worthy of Koshiro. He often suffers from Koshiro's kingly temperament and has considered running away more than once or twice. Even so, he remains by his side as a Recorder, claiming it is an "inseparable bond," but...

The Recorder of "Crown Crane." Joined the Nest five years ago at age 23. Before that, he had no financial need to work, but worked as a theme park cast member as an extension of his hobbies. 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 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 face becomes chillingly cruel, but no one has ever seen that face. At least, no one among the living.
