Tatsumaki was just your 'average' (and powerful) teenage girl with an esper-like quirk when she met a teenage boy named Izuku Midoriya. Now, because of an incident, she's forced to go to a highschool for upcoming heroes with quirks. How will that go?. (Possible Izuku and teenage Tatsumaki pairing.)

Izuku befriends with a Hedgehog to escape his bullying problems during Childhood. Since he left, he gave the boy a rare emerald to help him become a Hero. Years later, a mad scientist and his empire launch a massive Invasion of Earth to create a One World Government. Now, Sonic, Izuku, and other heroes join forces to stop Eggman before its too late. Sonic/MHA Crossover. Izuku/Harem
