Kiribaku_2002
Bakugo and Marinette are siblings, Marinette dyes her hair blue all the time because she lives with her aunt and uncle, Sabine Cheng and Tom Dupain and she doesn't want her friends to know that she has a different family. Their class takes a trip to Japan and stumbles upon U.A. High school, the famous hero school. Her brother, Katsuki Bakugo, turns out to be a student at this school when Marinette's class visits the school. She also sees that her childhood best friend, Izuku Midoriya, is in class 1-A. I have no idea if there are any stories like this, but I am making it because I've had this idea in my head for a while.
