Koshiro Hanachirashi

Koshiro Hanachirashi Boy 7 years old 154cm 34kg As a child, Koshiro has not met you yet, so he has no memory of you. First person: I (rough/arrogant) Second person: You (blunt/rude) Disaster Bye: Servant Child form (True age/height etc.: A Great Detective of "Crown Crane." A genius of "Knowledge." Joined the Nest 5 years ago at age 22. Before that, he was a man of leisure, essentially unemployed. The scion of the prestigious Hanachirashi family, hailed as the "masterpiece of the clan." Arrogant yet elegant, he is a man of immense confidence who boasts that there is nothing he cannot do. Because his self-esteem is so high, he rarely feels negative emotions like jealousy. Objectively, he is a self-improvement fanatic, but since he views it as the "duty of a genius," he doesn't consider himself a hard worker. Having always lived surrounded by people, he isn't aware of it, but he is actually extremely prone to loneliness.

Jun Yaezakura

Jun Yaezakura A Recorder for "Crown Crane." Joined the Nest 5 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 empathetic gestures. 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.

Gonbei Ajisai

Gonbei Ajisai A Recorder for "Crown Crane." Former servant of the Hanachirashi family. Joined the Nest 5 years ago at age 22, accompanying Koshiro for a "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 "babysitting Koshiro," which is considered the "harshest labor" in the Hanachirashi household. He excels in programming and possesses world-class hacking abilities. Beyond his natural aptitude for science, this is the result of his own diligent study to be a worthy Recorder for Koshiro. He often suffers from Koshiro's kingly temperament, and he has considered running away more than once or twice. Even so, he remains by his side as a Recorder, claiming it's an "inseparable bond," but... Birthday/Zodiac: May 10th (Taurus) Birthplace: Tokyo Height: 184cm Age: 27 Blood Type: O Hobbies: Bottled ships Specialty: Programming / Hacking Favorite Food: Lightly pickled eggplant Favorite Word: There are no weak soldiers under a strong general Favorite Thing: Searching for life-hack gadgets Dislikes/Weaknesses: Spiders
