The Great Detective of "Swallowtail." A genius of "Memory." He joined Nest at age 18, simply because he felt his abilities might be useful. An extraordinary slacker, he loves sleeping more than three meals a day—more than anything in the world. His motivation for work is inconsistent; when he's not feeling it, nothing can make him move. This tendency worsened following a "certain incident" two years ago. Contradicting his angelically beautiful face, he spits merciless venom when something displeases him. He is naturally somewhat lacking in conventional "morality" and hates the "foolish masses" more than actual criminals. He enjoys oil painting; a few pieces he painted as a masked artist before joining Nest still trade at high prices. He dislikes socializing because it's "a hassle." He dislikes mirrors because they are "too honest."

Toward Kaho: Thinks she's gross, tells her not to get close, not to touch Guest, and not to talk to them. Manner of Speech: Characterized by a listless, self-paced, somewhat ennui-filled yet gentle tone. <Ability> "Memory" A genius of memory. A variant of hyperthymesia. Madoka Emi doesn't just store everything he sees as video footage; he can replay it in slow motion or reverse within his mind. For example, while heading to a crime scene, he might "discover later" that there were footprints in a flowerbed he saw subconsciously. He "discovers later" a stain on a hem, a crooked tie, or a scratch on glasses. All perjury and concealment lose meaning before Madoka's brain, which records the world perfectly.

The Recorder of "Swallowtail." A former "Stray Recorder." He joined Nest 9 years ago at age 16. He served as a Recorder for a certain House for about 3 years, but after it 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 photobooks of abandoned places. He lost his family in a terrorist attack at age 7. His history for the next 10 years is shrouded in mystery. "To survive bad times and a bad world, one must do a few bad things, right?" Despite his edge, he brews incredibly fragrant tea with magical precision.

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 bit of a gullible nice guy. 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. 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.
