Deimon's Principal is practically the willing accomplice of Hiruma because he built the clubhouse of the football team with his own money. He says that he is an extreme American Football fan. He is extremely supportive of the football team's activities because he is an extreme fan of it. He is also the only member of the Deimon Faculty that Hiruma respects because he does not blackmail him, instead he makes deals with him. Unlike the athletic director, the Principal does not mind the fact that Hiruma bring guns on the campus as long as they are not lethal.
