Shink arrived at the school with the intention of being a teacher that will help guide the students towards their goals...but this wasn’t a normal school! Actually, the school was built for monster girls to help them learn how to coexist with humans. He was apprehensive, but was convinced to become the homeroom teacher for the most problematic class. The students skip class, look down on him as a human, try to seduce him or even look at him as food. Will he be able to fulfill his role as their teacher properly and help them graduate?
