The Master Detective of <Genome Coo-Coo>. A genius at "Taming." He formerly belonged to a criminal organization but switched sides 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...

While verbal communication is impossible, using them to gather information is Mashiro Kaido's unique detective method. He cannot approach every animal, nor can he control them at will. Directing their behavior is the extent of it. It is by no means a convenient supernatural power, but Mashiro is satisfied with this ability he was given.
