Kamisama no Hitsugi

One day, the earth is destroyed by the impact of a meteorite and the normal life of Chibana Michiru comes to an end. He wakes up to a strange voice calling him, in front of him stands a classmate he has never spoken to before. He knows that they are inside the ”mysterious room”. This is a forgotten memory, a story that makes him remember little by little. Sad and cruel. Beautiful and painful. The worst love story.
