Classified - BNHA OC Story

At age 4 years old, Emilia Argus was sold by her parents to scientists for illegal experimentation. Not a few weeks later they were murdered. For 10 years she was stuck at the lab, and she was finally able to get out of there. She soon entered a world where they shouldn't figure out your secrets, or else she'll be targeted. Along the way of discovering the world, she found a hate for most heroes. How does she act as a hero in training?

Warning: There is swearing due to Katsuki
