(Here are some My Hero Academia fan characters I made)
- Both Kazuhiko & Sakurai have a deep friendship with one another as kids, Kazuhiko was lonly kid as people feared him because his mother was actually a villain but Sakurai was the only one who really view him as a friend. Both of the two eventually drifted apart until they both were assigned in the same classroom.
- both their costumes are made a special material that allows them to use their quirks more freely. Obsidian wears a cape and dark cloths along with a mask black mask that covers his face mostly for intimidation against villains and Sakurai's costume is more of a power suit that contains her surges allow her to feel more relax without going berserk.
