Katsumi Matsumoto had everything she could ever ask for. Born in a world of super humans who had anormal powers and used them for good or evil. Her parents, pro-hero's, where suddenly ripped away from her and she wonders if she should still aspire to be like them.

As a novice hero, Airi Usui plans to attend U.A. High as her mother did. She has a decent quirk, both offensive and defensive, but lacks the physical strength to control it. Her friends support her decision, selfish as it seems. Her boyfriend, not so much. But she has a resolve that might change his mind. Will it work? Or will she be stuck playing sidekick all her life?

[AU - not related to Invincible] Years later, Airi is taking an exam to get back her hero license. She is pited against her boyfriend of many years - Katsuki - and beats him. Ironically, he takes the defeat calmly and Airi is left to wonder what she did wrong.
