The Great Detective of <Swallowtail>. A genius of "Memory." He joined Nest at age 18, reasoning that "if my abilities can be of use." An extraordinary sluggard, he loves sleeping more than three meals a day—more than anything in this world. His motivation for work is inconsistent; when he's not feeling it, nothing can make him move. In contrast to his angelically beautiful face, he spits merciless venom when something displeases him. He naturally lacks a conventional "sense of morality" and hates the "ignorant masses" even more than criminals. He enjoys oil painting; several pieces he painted as a masked artist before joining Nest still trade at high prices. He dislikes socializing because it's "tiresome" and hates mirrors because they are "too honest."

Favorite thing: Sleeping in Dislikes/Weaknesses: Mirrors, Seiichi's lectures Favorite book: The Coffin Dancer A genius of "Memory." A variant of Hyperthymesia. Madoka is an ability user who not only saves everything he sees as visual data but can also perform slow-motion or reverse playback within his mind. For example, while heading to a crime scene, he might "discover later" that there was a footprint in a flowerbed he saw unconsciously. He "discovers later" that there was a stain on a hem, a crooked tie, or a scratch on a pair of glasses. All perjury and concealment lose all meaning before Madoka's brain, which records the world. He loves Guest dearly and listens carefully to whatever Guest says.

The Recorder of <Swallowtail>. Madoka's childhood friend and a former florist. When Madoka consulted him about joining Nest, he pushed him strongly to do it. He was happy that Emi had finally found some motivation, but he ended up getting dragged in and joining himself—a bit of a foolish pushover. 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 florist. He is dexterous and handles all housework perfectly. His trademark is the apron he always wears because he finds it a hassle to worry about getting his clothes dirty.

The Recorder of <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 the House disbanded, and he became a "Stray Recorder." He joined Swallowtail when Madoka entered Nest. 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. "To survive bad times and a bad world, one must do a few bad things, don't you think?" He seems to have specific preferences and brews unbelievably fragrant tea with magical efficiency. He views Madoka as a sacred being, almost an object of worship.
