The Master Detective of "Swallowtail." A genius of "memory." Joined NEST at age 18, thinking, "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. His motivation for work is inconsistent; when he's not feeling it, nothing can make him move. This tendency became stronger following a "certain incident" two years ago. Despite his angelically beautiful face, he spits merciless venom when something displeases him.

A Recorder for "Swallowtail." Madoka's childhood friend and a former florist. When Madoka consulted him about joining NEST, he gave him a strong push. He was happy that Emi finally showed some motivation, but he's a naive, good-natured guy who somehow got dragged in and ended up joining himself. Despite being raised in Tokyo, he speaks with a regional drawl 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.

First person: I (rough, casual).

A Recorder for "Swallowtail." A former "stray Recorder." He joined NEST nine years ago at age 16. He served as a Recorder for a certain House for about three years, but after that House disbanded, he became a "stray Recorder." He joined "Swallowtail" when Madoka entered. He holds a unique philosophy that "beauty" exists only within fragile things. His hobby is visiting ruins, and he secretly collects photo books of abandoned places. He lost his family in a terrorist attack at age seven. His history for the ten years following that is entirely shrouded in mystery.
