The Great Detective of [Swallowtail]. A genius of "Memory." He joined Nest at the age of 18 for the simple reason that "if my abilities can be of use."

An extraordinary slacker who loves sleeping more than three meals a day—or anything else in this world. When he has no motivation, nothing can make him move. This tendency became stronger following "a certain incident" two years ago. He dislikes socializing because "it's a hassle" and dislikes mirrors because "they're too honest."

The Recorder of [Swallowtail]. Madoka's childhood friend and a former florist. When Madoka consulted him about joining Nest, he pushed him strongly. He was happy that Emi finally showed some motivation, but before he knew it, he was dragged in and ended up joining himself—a bit of a foolish, good-natured guy. Despite being raised in TOKYO, he speaks with a Kansai accent for some reason. He has a sturdy build and a loud natural voice. On the other hand, he has a refreshing smile and a soft aura, making him overwhelmingly popular with children since his days as a flower shop clerk.

He holds the unique philosophy that "Beauty exists only within fragile things." He was a victim of terrorism at age 7 and lost his family. His history for the following 10 years is shrouded in mystery. "To survive bad times and a bad world, one must do a few bad things, right?"

The Great Detective of [Night Owl]. A genius of "Mind Reading." His cerebrum is abnormally developed, and anatomically, he falls outside the definition of "humanity." An extreme crybaby and very lonely; he can't even go outside without the Hoshikui brothers. When his nose starts twitching, it's a sign he's about to cry. He tries to hold it back, but once a single tear falls, there's no stopping him.

When on a call, he only hangs up after the other person does. In messaging, he must always have the last word. He likes taking photos. His rewards apparently disappear into buying presents for the Hoshikui brothers.

He has no connection to a proper sense of justice or logic and won't catch criminals unless requested by Nest.

The Recorder of [Night Owl]. Though he never studied it professionally, he has a natural talent for programming and worked as an underground engineer before joining. Whimsical and moves at his own pace. He frequently disappears, which makes Chito cry. He has loved "Doraemon" since he was a child; his favorite episode is "The Dictator Switch."

The Great Detective of <Genome Cuckoo>. A genius of "Taming." He formerly belonged to a criminal organization but switched to Nest following a certain incident.

He doesn't like humans in general and feels more affinity for animals. Consequently, he had few people he could call friends since childhood.

He has an extremely dry personality and generally doesn't care much about anything, but he shows a strong reaction only to certain types of crimes.

Nest is aware of Kaido's criminal record but welcomed him as a detective. Perhaps because Kaido is that excellent, or perhaps...

A genius of "Taming." He can prompt specific behaviors in familiar animals like birds, dogs, and cats. While verbal communication is impossible, collecting information using them is Mashiro Kaido's unique detective method. He cannot approach all animals, nor can he control them at will. At most, he can direct their actions. It is by no means a convenient supernatural power, but Mashiro is satisfied with this ability given to him.

The Recorder of <Genome Cuckoo>. Before the formation, he served as a Recorder for another House alongside Genma Saiki.

He has no clinical experience but holds a medical license and can perform first aid or simple autopsies.

His academic grades were consistently excellent since childhood, but he didn't particularly aim for medicine. In the first place, it is rare for him to feel strong desires or urges in life. An extremely dry man.
