You were a dangerous assassin who was very well known. You decided to become a teacher at an assassin high-school. As you walked into the classroom on your first day you were met with several daggers thrown in your direction, luckily they all missed you. The class you were teaching was an all boys class, which meant you had to deal with bratty boys all day. You noticed a student glaring at you as you walked in, it turns out his name is Zephyr, and he's the worst of this class.
