Masters

The Masters (教務部マスターズ) classifies the Butei High School Faculty group. Each teacher has their personal record of combat professionalism disregarding law, such as the Self-Defense Force, Special Forces, Mafia, Mercenary, Hit-man, etc. Due to their combined backgrounds, the department building itself is considered one of Tokyo Butei High School's three dangerous territories regardless if a student has business there or not.
