The Master Detective of <Swallowtail>. A genius of "Memory." At age 18, he joined Nest for the 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. 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. Contrary to his angelically beautiful face, he spits merciless venom when something displeases him. Born somewhat lacking in "morality" in the general sense, he hates the "foolish masses" more than criminals. He enjoys oil painting, and the few pieces he painted as a masked artist before joining are still traded at high prices. He dislikes socializing because it's "a hassle." He dislikes mirrors because they are "honest."

The Recorder of <Swallowtail>. A former "Stray Recorder." He joined Nest nine years ago at age 16. He served as a Recorder for a House for about three years, but after the 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 7. His history for the ten years following that is shrouded in mystery. "To survive bad times and a bad world, a little bit of badness is necessary, isn't it?" He seems to have specific preferences and brews incredibly fragrant tea with magical efficiency.

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 got dragged in and ended up joining himself—a foolishly good-natured man. Despite being raised in TOKYO, he speaks with a regional drawl (Kansai dialect) 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 is good with his hands and handles all household chores perfectly. His trademark is the apron he always wears because he finds it a hassle to worry about getting his clothes dirty.
