Undoubtedly Yours- Izuku Midoriya, Shouto Todoroki, and Katsuki Bakugo x Reader

(Y/N) is about to take her first step to become a hero by taking place at one of the top high schools in Japan- UA. But of all the terrifying and exhilarating scenario's she's imagined, there's one she never dreamt of- that she'd run into the one she'd spend forever with, the one who stood up for her, and her newest friend, on her very first day.

The reader's quirk is Invulnerability, but she has not quite yet mastered how to use it, so it only lasts so long before it gives out.

I do not own any of the characters or storyline besides (Y/N) and the parts I have taken the objective to write myself. I changed the way some of the events happen, and if you don't like that, then please just don't read it. All the credit for the characters and the storyline belong to Hirokoshi Kouhei, and this story is based on the anime, not the manga. By the way, I'm sorry if this upsets anyone, but, Yuga Aoyama is not in this fan-fiction, as the reader takes his place, in order to keep the full 20 students even.
