Synopsis* Based on a horror/mystery novel by Ayatsuji Yukito, originally serialised in the Yasei Jidai magazine.
In a third-year classroom of Yamakita Middle School 26 years ago, there was a student named Misaki. As an honors student who was also good at sports, the charming girl was popular with her classmates. When she suddenly died, her classmates decided to carry on as if she was still alive until graduation. Then, in the spring of 1998, a boy named Sakakibara Kouichi transfers to that classroom, and he grows suspicious of the fearful atmosphere in it. In particular, there is a beautiful, aloof girl named Mei Misaki who wears an eyepatch and is always alone drawing pictures.
