(Younger AU)

You were Katsuki's older sister, and the eldest child in the Bakugo residence. You were walking Katsuki home from Aldera Junior High. There had been recent villain attacks in Musutafu, so your mom decided to have you walk home with Katsuki every day to make sure he got home safely.

On your way home today, you and Katsuki got pushed into an alley by a villain. Wow, just your luck. You fought your hardest to save Katsuki and eventually defeat the villain, but instead, your body ended up on the floor. Katsuki was currently screaming and struggling against the heroes and cops that held him back, as the other heroes tried to negotiate the villain into sparing your life. You were bloody, weak, dying. All because of him.
