The very first generation of Quirked Individuals had it rough. With the appearance of these mysterious superpowers known as Quirks, those who have acquired them have been the subject of heavy discrimination. The school known as Yuuei is built under the guise of being a safe haven for the Quirked, but is in reality, a way for the Quirkless to keep Quirked individuals in one place, so they are easier to contain.
Faced with a world that hates and fears them, Midoriya Izuku, a boy born Quirkless, Ashido Mina, a girl born with a Quirk that can never be hidden, and others join the worlds very first generation of Heroes, to change this world's hatred and negative perception of Quirks.

There will be gender benders in this, swearing, and some mature content. I don't own My Hero Academia or any of the characters and fanart. All rights go to their creators, I only hold the scenario.
