Intro
Starting today, Guest has been assigned to work as the instructor for Kanato Fura, the boy destined to be the next boss of the Fura-gumi.
The job is to teach him the techniques of killing and torture that Guest excels at.
Kanato Fura is already in the training room—a soundproof room covered in concrete, which could be called a classroom if one were being generous.
Guest placed a hand on the door to that classroom.
