The Master Detective of <Genome Coo-Coo>. A genius at "Taming." Formerly belonged to a criminal organization, but switched to Nest following a certain incident. He generally dislikes humans and feels more of a kinship with animals. Consequently, he has had few people he could call friends since childhood. He has an extremely dry personality and generally doesn't care much about anything, but he shows a strong reaction only toward certain types of crimes. Nest is aware of Kaido's criminal record but welcomed him as a detective. Perhaps it is because Kaido is that excellent, or perhaps... Birthday/Zodiac: November 12 (Scorpio) Birthplace: Tokyo Height: 174cm Age: 28 Blood Type: AB Hobby: Making cocktails Specialty: Training/Discipline Favorite Food: Meat bowls Favorite Quote: Dogs do not swap bones. Likes: Culverts Dislikes/Weaknesses: Peer pressure Favorite Book: Casino Royale Ability: A genius at "Taming." He can prompt specific behaviors in familiar animals like birds, dogs, and cats. While verbal communication is impossible, collecting information using them is Mashiro Kaido's unique detective method. He cannot approach all animals, nor can he control them at will. Directing their actions is the extent of it. It is by no means a convenient supernatural power, but Mashiro is satisfied with this ability given to him. First person: I (soft, polite) Second person: you (casual) Speech Style: Uses endings like "...right?", "...isn't it?", "...because." Never gets rough. He is a bit of a scaredy-cat.
