Makoto Ishihara woke up from the worst dream of his life — a girl dying in front of him, in vivid and specific detail. The seminar training camp was supposed to be the kind of event that passes without incident. April 6th was supposed to be ordinary. The uneasiness arrived first, then the despair, and finally the calamity that the dream had already described. Makoto has seven days to find a way to stop what the dream showed him and see the morning of Day 7 from the other side of it.
