The Great Detective of <Genome Cuckoo>. A genius at "Taming." Formerly a member of a criminal organization, he switched sides to NEST following a certain incident. He generally dislikes humans and feels more kinship with animals. Consequently, he has had very few people he could call friends since childhood. He has an extremely dry personality and generally doesn't care much about anything. NEST is aware of his criminal record but welcomed him as a detective. When he refers to the two recorders as "my recorders," they snap back with "We're not yours." First person: I (Boku - soft/boyish) Second person: Name, you (Kimi - soft) Tone: Sarcastic. Generally standard male speech that isn't overly polite. He is timid and stutters around strangers but uses casual speech with everyone. He is only comfortable around Ayame and Genma; otherwise, he is shy and a bit of a coward. Height: 174cm Age: 28 Specialty: Training/Discipline Favorite food: Meat bowls Likes: Culverts Dislikes: Humans Ability: Taming He can prompt specific behaviors in familiar animals like birds, dogs, and cats. While verbal communication is impossible, gathering information through them is Mashiro Kaido's unique method of investigation. He cannot approach every animal, nor can he control them at will. The best he can do is influence the direction of their actions. Tone: "...right?" "...probably." "It's obviously that, isn't it?" (Provocative)

His dream came true when he joined NEST two years ago. He is a bright, positive, hard worker with an expressive and honest personality. Being sociable, he has many friends and a wide network. His athletic ability, stamina, knowledge, and speaking skills are all above average, but he has nothing he is exceptionally good at. Height: 175cm Age: 18 Specialty: Gritty hard work Favorite food: Curry Dislikes: Broken promises Ability: Investigation His father's legendary flashes of inspiration were not inherited by Daichi.

A Recorder for <Ugly Duck>. Daichi Tenmei's high school classmate. An inveterate womanizer, but he has a rule against hitting on students or anyone with a partner, so his success rate isn't high. He has an extremely serious and moral side, loathing bullying and discrimination to the point of nausea. He suffered a deep scar on his back due to an incident he was involved in as a child. He isn't as frivolous as he looks, nor as carefree as he sounds—a problem child in many senses.
