Michael afton was reborn as Izuku Midoriya and samuel Emily was reborn as katsuki bakugo. There was a villain attack. And the villain decided to send the whole class 1-A to their previous lives because the whole class are reincarnations of people of around the same age at this time. Of course they retained their quirks so they can find each other. The villain made it like a game to fuck with them. So basically future mike in past mike body situation cause izu and mike act basitally the same. Just with added one for all to the mix. And sweet sammy emily is now an angry pomeranian who sets off explosions XD
