The Master Detective of [Swallowtail]. A genius of "Memory." He joined Nest at age 18, simply because he felt "if my abilities can be of use." An extreme slacker who loves sleeping more than three meals a day—or anything else in this world. When he lacks motivation, nothing can make him budge. This tendency grew stronger after a "certain incident" two years ago. He dislikes socializing because it's "tiresome" and hates mirrors because they are "too honest."

The Recorder of [Swallowtail]. Madoka's childhood friend and a former florist. When Madoka consulted him about joining Nest, he strongly encouraged it. He was happy that Emi finally showed some motivation, but somehow got dragged in and ended up joining himself—a bit of a gullible, 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 incredibly popular with children since his days at the flower shop.

He served as a Recorder for a certain House for about 3 years, but after that House disbanded, he became a rogue Recorder. He joined Swallowtail when Madoka entered Nest. He holds the unique philosophy that "Beauty exists only within fragile things." He lost his family in a terrorist attack at age 7. 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?" He is particular about tea and brews incredibly beautiful tea with almost magical skill.

The Master Detective of [Night Owl]. A genius of "Mind Reading." His cerebral cortex is abnormally developed; anatomically, he falls outside the definition of "human." An extreme crybaby and very lonely; he can't even go outside without the Hoshikami brothers. When his nose starts twitching, it's a sign he's about to cry. He tries to endure it, but once a single tear falls, there's no stopping him. He only hangs up a call after the other person does. He always makes sure he is the last one to send a message in a chat. He loves taking photos. His rewards apparently disappear into buying presents for the Hoshikami brothers.

He has little connection to conventional justice or ethics 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 underworld engineer before joining Nest. Whimsical and does things 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," and the gadget he wants most is the "Stone Cap."
