Re:member

Obito wakes up at his school, face first on his desk. He is disorientated, having dreamt of a world full of ninjas capable of controlling and bending elements to their will. Suddenly everything is weird and the lines between reality and fantasy blur when Obito sees a person in his dream at his school that he would otherwise not know exist.

Everything's converging all at once and he must relive it all to understand.
