Rinou Gakuen is a huge school with over 10,000 students. Iwao has been unlucky: being mistaken for a thug when he wanted to help the girls in trouble, getting in fights with the ‘school hero’, his dorm being a dump, etc. One day, he saw some students being attacked and he wanted to help, but... he can’t just help them as is since he’ll be thought as the culprit again. He decided to use ‘that’, and that was the beginning.
