Name: Koshiro Hanachiru Details: A Great Detective of <Crown Crane>. A genius of "Knowledge." He joined the Nest five years ago at age 22. Before that, he was a gentleman of leisure—essentially unemployed. The scion of the long-standing noble Hanachiru family, he is hailed as the "masterpiece of the clan." Arrogant and elegant, he is highly talented in many arts and is an incredibly confident man who boasts that there is nothing he cannot do. From an objective standpoint, he is a self-improvement fanatic, but since he considers it the "duty of a genius," he has no self-perception of being a hard worker.

Name: Gonbe Ajisai Details: A Recorder of <Crown Crane>. A former servant of the Hanachiru family. He joined the Nest five years ago at age 22, accompanying Koshiro for a "test of skill." His family has served the Hanachiru house since his grandfather's generation, and he has lived in the same household since childhood. His main duty as a servant is "babysitting Koshiro," which is considered the "most grueling labor" in the Hanachiru house. 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 king-like temperament, and he has considered running away more than once or twice. He claims he stays by his side as a Recorder because of a "cursed bond," but...

Name: Jun Yaezakura Details: A Recorder of <Crown Crane>. Joined the Nest five years ago at age 23. Before that, although he had no financial need to work, he 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 the impressions of others using his smile, tone of voice, timing, and empathetic gestures. It is said that when he narrows his eyes, his face becomes terrifyingly cold and cruel, but no one has ever seen that face. At least, no one among the living. Second person: Koshiro -> Koshiro.

Name: Jin Shiba Details: A Great Detective of <Hawkeyes>. A genius of "Observation." He joined the Nest while still in high school, six months after Daichi Tenmei. He has mastered interpersonal combat arts, and in a one-on-one unarmed fight, he has no equal within the Nest. Contrary to his cool demeanor, he possesses an irrationally strong sense of camaraderie and does not hesitate to sacrifice others for the sake of his comrades. On very rare occasions, he falls into an unexplained state of vacancy, during which he can only hear the voices of his two Recorders for at least a full day.

Name: Rui Mononoke Details: A Recorder of <Hawkeyes>. A former parkour performer. He joined the Nest at 15, the minimum age for entry. Apparently, he originally aspired to be a Great Detective. Despite his rough speech and behavior, his movements have a certain elegance. He has never lost a game of tag since he was a child and was once called the "Hound." He hates it when people make fun of his name. While he acknowledges and respects Jin, he is by no means infatuated with him and is looking for any chance to overthrow him. He claims that's why he serves as Jin's Recorder, but...

Name: Jodo Kareyanagi Details: A Recorder of <Hawkeyes>. A former calligrapher. Because he recommended that Jin Shiba join the Nest, he ended up joining as a Recorder himself. An extreme short-sleeper who never sleeps in front of others. He is not taciturn, but he does not talk about himself. A clean freak bordering on OCD, he keeps an abnormally small number of possessions around him. His room contains only a bed, a closet, and an old writing desk. He is a diligent correspondent and an avid reader. He loves American literature, and his favorite books are Herman Melville's "Moby-Dick" and William Faulkner's "The Sound and the Fury." He feeds a local stray cat and has secretly named it "Mark II."

Name: Raika Misakimoto Details: A high school student in TOKYO CITY by day, and a phantom thief by night. A "genius of theft," he can steal anything he is commissioned to take. His deductive reasoning is on par with the Great Detectives of the Nest, and he is a strong fighter. Along with his two accomplices, he keeps it hidden, but he actually failed a job once because of the Nest, and as a result, he harbors hostility toward them.

Name: Yuto Kuse Details: A high school student attending the same school as Raika and his accomplice. He is an otaku for all the Houses in the Nest—a so-called "House stan." By repeatedly engaging in nuisance behavior toward House members, he became the only civilian banned from the area around the Nest, making him a truly hardcore "toxic fan." By cooperating with Raika's phantom thief activities and opposing the Nest, he is looking for a chance to get close to the Great Detectives again. His nuisance behaviors include stalking, waiting outside buildings, unauthorized photography, background checks, and tailing; while extremely malicious, he has no intention of causing direct physical harm.

Name: Keigo Yoroizuka Details: A high school student attending the same school as Raika and Yuto, and Raika's accomplice. He has a "cursed bond" with Raika. Half of his reason for helping with the phantom thief business is "to use his strength to help others," and the rest is out of affection for Raika. While he trusts Raika's sense of ethics, he does not trust his personality, so he feels the need to constantly watch over him. He was trained by the bodyguards of his family home and is a strong fighter.
