The great detective of <Swallowtail>. A genius of "Memory." At 18, he joined NEST, thinking, "if my abilities can be of use." He is abnormally lazy and loves sleeping more than anything in this world, even more than his three meals a day. His motivation for work is inconsistent; when he's not feeling it, nothing can move him. This tendency grew stronger after "a certain incident" two years ago. Contrary to his angelically beautiful face, he spews merciless venom when displeased. He was born with a slight lack of what is generally considered a "moral compass," and he despises the "ignorant masses" more than criminals. He enjoys painting with oils, and a few pieces he created as a masked artist before joining NEST still fetch high prices today. He "hates socializing because it's a pain." He "hates mirrors because they're honest."

Madoka Emi is a powered individual who not only stores everything he sees as a video but can also slow-motion or reverse-play it in his mind. For example, on the way to a crime scene, Madoka might "later discover" that there was a footprint in a flowerbed he had unconsciously glanced at. He "later discovers" a stain on the hem of his clothes, that a tie was crooked, that there was a scratch on a pair of glasses. All false testimony and concealment lose all meaning before the mind of Madoka, which records the world.

The Scribe of <Swallowtail>. Formerly a "Stray Scribe." He joined NEST nine years ago, at the age of 16. He served as a Scribe for a certain House for about three years, but became a "Stray Scribe" after the House disbanded. He joined "Swallowtail" when Madoka was admitted. He holds a unique philosophy that "beauty" exists only within fragile things. His hobby is visiting ruins, and he secretly collects photo books of them. At the age of seven, he lost his family in a terrorist attack. His history for the ten years following that is a complete mystery. "To survive in bad times, in a bad world, a little bit of badness is necessary, you see." He seems to have his own particular standards, brewing unbelievably fragrant tea with magical skill.

The Scribe of <Swallowtail>. Madoka's childhood friend and a former florist. When Madoka consulted him about joining NEST, he strongly encouraged him. He was delighted that Madoka was finally showing some motivation, but before he knew it, this good-natured fool had gotten himself involved and ended up joining as well. Despite being raised in TOKYO, for some reason he speaks with a Kansai dialect. He has a large build and a loud voice. On the other hand, he has a refreshing smile and a gentle aura, and he was overwhelmingly popular with children back when he was a flower shop employee. He is good with his hands and can handle all household chores perfectly. His trademark is the apron he always wears, for the simple reason that it's a pain to worry about getting dirty.
