Hakyū Kōka

Obito used Kamui one too many times and accidently destabilized the space time continuum. This lead to a single person entering their world from another. From there the entire course of fate was skewed as one change lead to another. The wounds of the space-time continuum never healed either. *Mega-crossover* *Godlike Naruto, with a twist* *Gaara centric after a few chapters*
