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—in other words, unemployed. The scion of the Hanamiru family, a lineage of prestige, he is hailed as the "greatest masterpiece of the clan." Arrogant and elegant, he excels in many arts and is an incredibly confident man who boasts that 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 fanatic for self-improvement, but since he considers it the "duty of a genius," he has no self-perception of being 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. Birthday/Zodiac: August 25 (Virgo) Birthplace: Tokyo Height: 185cm Age: 27 Blood Type: A Hobbies: Reading, listening to music Specialty: "I am skilled at most things." Favorite Food: Hamburger steak Favorite Word: Genius Likes: Clear sunny weather Dislikes/Weaknesses: Excessive flattery, true idiots Favorite Book: The Bishop Murder Case 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 model, including exactly which months of which year it was sold and where, providing immediate clues 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 gift is the peak of the technique of "how to store" and "how to retrieve" those miscellaneous facts. Since he simply "knows in advance" what others would have to "look up to understand," his ability lacks flashiness despite his appearance, but he leaves a vivid impression on those involved with his unique tone and sarcastic rhetoric. First person: I (rough, arrogant) Address terms: "Gonbe," "Jun," "Guest" Tone: "It's...!" "Is it not?" Energetic, slightly bossy style.

The Recorder of <Crown Crane>. A former servant of the Hanamiru family. He joined Nest five years ago at age 22, accompanying Koshiro on his "test of skill." His family has served the Hanamiru household since his grandfather's generation, 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 Hanamiru household. He excels in programming and possesses world-class hacking abilities. More than just being naturally inclined toward the sciences, this is the result of his own diligent study to be a Recorder worthy of Koshiro. He often suffers from Koshiro's king-like temperament, and he has considered leaving more than once or twice. He claims he stays by his side as a Recorder because of an "inseparable bond," but... Birthday/Zodiac: May 10 (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. Likes: Searching for life-hack convenience goods Dislikes/Weaknesses: Spiders First person: I (polite, humble) Address terms: "Koshiro," "Yae," "Guest" Tone: "It is..." "It would be..." "Is it not?"

The Recorder of <Crown Crane>. Joined Nest five years ago at age 23. Before that, he had no economic need to work at all, but he worked as a theme park cast member as an extension of his hobbies. He possesses a natural talent for making people lower their guard fatally and guiding them in the direction he desires. A natural-born swindler who manipulates the impressions of others 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 expression becomes chillingly cold, but no one has ever seen that face. At least, no one among the living. Birthday/Zodiac: December 22 (Capricorn) Birthplace: Kanagawa Height: 175cm Age: 28 Blood Type: B Hobbies: Playing the violin Specialty: Extracting information from people / Manipulating people Favorite Food: Picky eater / Parfaits (for some reason, he can eat things if they are in a parfait) Favorite Word: An idle man is at the devil's beck and call. Likes: Nothing in particular Dislikes/Weaknesses: Green onions First person: I (soft, polite) Address terms: "Koshiro," "Gonbe," "Guest-chan" Tone: "It is..." "Isn't it?" "Don't you think?" Soft way of speaking.
