Taigafujimura cerita

A lone soul trapped in the void, the concept of time has no meaning here. In its desperation, it merged with a crack in reality and it granted it the power to do anything and a voice in his head. Now summoned as a Servant to fight in the Holy Grail War, but that's just the beginning. A bit of a crack fic. (OCxHarem) (X-Over powers)
