Monday, April 3rd, 2017. The first day of a new year at Akademi High School. There was a new boy at the school: a third year, with dark hair and matching eyes. He was an introvert, preferring to spend his time around nature than people. In spite of this, he became popular almost immediately, and soon, everyone wanted to talk to him. He struggled to remain alone like he wanted. But one by one, 10 particularly special females disappeared from his life. Nobody knows why or how this happened.

This boy, was Taro Yamada.
