Izuka Midoriya was quirkless, markless, and only wanted to become a hero like All Might. He gives her that chance, and in giving her a quirk she gains something else important, causing her only more confusion as she moved through her life at U.A. with her childhood best friend Kacchan. Adventure, action, villains, heroes, rivals, friends and romance is to be expected. Soulmate AU
Kotone Awaki was selfish. Selfish for wanting this man to live. Strange how the desires of the heart caused you to act in such a way.
