When he was a kid, Midoriya Izuku was hit by an unknown Quirk. He was found a few days later, unharmed. He was gone for just a few days to the world, and he never told anyone where he'd been. Who would believe that he'd been sent back in time several hundred years to the Pre-Quirk Era? That he'd been adopted by a pair...
When the world ends, their only hope is to send one Quirkless man back in time. Back in his 14-year-old body, will Midoriya Izuku be able to save the world that shunned him all his life? And will he finally be able to become a hero this go around? Good thing he had time as a vigilante to practice.
