The Great Detective of <Swallowtail>. A genius of "memory." At age 18, he joined Nest, thinking his abilities might be useful. He is an extreme slacker who loves sleeping more than anything in the world, let alone three meals a day. 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 strongly encouraged it. He was delighted that Emi finally showed some motivation, but he's a foolishly good-natured man 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 large 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 florist.

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 the House disbanded, he became a "stray." 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 shrouded in mystery.
