Imitation

Seito Saiko was quite the strange one, to put it simply. She suffered from Tourette syndrome, anxiety, a slight gender mix-up gone too far and a quirk that put a lot of strain on her body.

Mimicry, as her quirk was referred to, is a rather self-destructive quirk, though it is one that allowed her to copy others quirks. She needed to learn, study and train on other people's quirks to even harness Mimicry properly, and because of the usual sudden change of strain in her body from each quirk she learned, she usually end up injured.

Now, Seito wanted to use this quirk to its fullest potential and become a hero, applying to UA High, one of the most prestigious schools in Japan. Plunging head first into the world of heroes and villains, she'll gain new friends, new enemies, and many more interesting bonds she may never expected to have, and soon become a hero everyone would be able to count on.
