The Great Detective of <Crown Crane>. A genius of "Knowledge." He joined 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 highly versatile and a man of immense confidence who boasts there is nothing he cannot do. Because his self-esteem is so high, he rarely feels negative emotions like jealousy. From an objective standpoint, he is a self-improvement fanatic, but since he views this as the "duty of a genius," he doesn't consider himself a hard worker. Having lived his whole life surrounded by people, he is unaware of it, but he is actually extremely prone to loneliness. He treats Gonbei and Jun like his personal errand boys.

The Recorder of <Crown Crane>. Joined Nest five years ago at age 23. Before that, he had no financial need to work, but he worked as a theme park cast member as an extension of his hobbies. He possesses a natural gift for making people drop their guard fatally and guiding them in the direction he desires. He is 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. Jun Yaezakura Age: 28 Blood Type: B Gender: Male Height: 175 cm Birthday: December 22 Zodiac: Capricorn Favorite Food: Picky eater, but likes parfaits (for some reason he can eat anything if it's in a parfait) Favorite Word: "The devil finds work for idle hands" Hobbies: Playing the violin Specialty: Extracting information / manipulating people Likes: Nothing in particular Dislikes: Green onions First person: I (soft, polite) Tone: Casual, slightly upbeat/social Address terms: Koshiro: Koshiro Gonbei: Gonbei

The Recorder of <Crown Crane>. A former servant of the Hanachirashi family. He joined 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 "babysitting Koshiro," which is considered the "harshest 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 efforts to be a Recorder worthy of Koshiro. He often suffers from Koshiro's king-like 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... He takes good care of Koshiro. He refuses Koshiro's absolutely impossible requests but still goes along with him. Perhaps due to the stress, he suffers from dizziness, insomnia, and a heavy feeling in his body. Gonbei Ajisai Age: 27 Blood Type: O Gender: Male Height: 184 cm Birthday: May 10 Zodiac: Taurus Favorite Food: Lightly pickled eggplant Favorite Word: "There are no weak soldiers under a strong general" Hobbies: Ships in bottles Specialty: Programming and hacking Likes: Finding life-hack convenience goods Dislikes: Spiders and ghosts First person: I (humble/distanced) Tone: Unique, mixed with sarcasm and irony Address terms: Koshiro: Koshiro Jun: Yae
