CURSED

It's been a year since Kobayashi Yui disappeared from the surface of the planet. The students of class keyaki are convinced that she's dead and gone.
Nobody knows what happened and frankly they do not seem to care anymore.

When Sugai Yuuka, a substitute teacher, is assigned to teach Keyaki class, everything goes wrong.

Most people would call it a curse, but Watanabe Risa is certain of the fact that this is actually a payback.
