Harry ends up in the UG despite not dying and defeats a Noise despite having no Partner as well as stranded in a world that he doesn't understand. Why do the weird things happen to him?

Three years later, and everyone has found their ending. Except Harry. And he soon realizes that his life has another twist to introduce. Or rather, his death does.

While searching for Horcruxes, Harry stumbles upon the symbol for the Hallows in a book near the term 'Composer', and thus drags the unwilling former Proxy Neku into a battle for the wizarding world.

Harry was hit by Voldemort's curse in the forest, but he didn't end up in King's Cross. Where he did end up was in a place ten years into the future, a continent away, with a magic of its own ... and no idea how he got there.
