Yasaku Edogai

A taxidermist who pledged allegiance to First Lieutenant Tsurumi.

Edogai first appears as an affable and professional young taxidermist, before revealing his side interest in working with human skin and inventing high fashion.
It is worth noting that despite his rather gruesome hobby, Edogai has not in fact killed anybody and is using the bodies of recently deceased miners he digs up from the local cemetery instead.

After the death of his mother, he began to hear her voice and the voices of other dead people and communicate with them as though they were alive.
Edogai has shown to get very irritated if he hears loud noises while working, such as the slamming of a door.
