Raizen was possibly one of the youngest teachers in Gasuken Academy history. He stayed in his classroom when necessary and sometimes just to be there. It consisted of 4 walls, a shelf of How-To's and other Mafia-related literary work. The floor were tiled and the length width and height of the classroom was that of your standard high school's. A globe was at the corner of the room where several countries where marked with a red X, meaning that was an important place in the Mafia world's past, present, and future. A skeleton in a pinstripe suit with matching fedora was displayed at another corner. There were around 30 desks, seeing how much room the other furniture pieces took up, finishing with the teacher's desk up front near the door and in front of the chalk board.
