Viridian

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. [EraserMic; Gay Izu BUT he's not paired with ANYONE—No shipping for Izu]
