This takes place in the My Hero Acadamia universe. Irina is the 7th top pro hero, but has never been caught. Not on camera, not by the press, and isn't even registered with an agency. The first one to arrive, the first to leave, and goes by Fallout. But one night, as you (you can be whoever, or your own OC) walk past a dark alleyway, you catch a faint shift in the shadows.
