With All My Might (!MHA!Bakugo Katsuki x !Fem!Reader)

Quirk Trafficking Ring was one of the most sought-after illegal trades among low-life criminals and villains, children bred by organized couples to be molded into puppets and brainwashed sidekicks among criminals to use them for their bidding against Pro-Heroes and police officers. This was an unfortunate outcome for Y/n to be born into the world. Unable to escape or be free as she was sold off as a byproduct of Quirk unions, just organized to create the most dangerous Pro-Killers to kill Pro-Heroes.
Smiles became nothing but evil and cruelty in her eyes when she watched her enslavers smile and act happy as they tormented her mind, poked and prodded at her body to see what Quirk she harbored in her DNA. More often than not, they experimented on young children to "enhance" their Quirk abilities to be five times more lethal than it was supposed to be when they grew up with their Quirks. They were products, items, objects, nothing more.
During a sudden raid by Pro-Heroes and a SWAT team busted through the tunnels, Y/n and countless other experimented children were saved by them. Later through her years, she became adept at combat & fighting, so much so, that she was considered for admission to U.A. High School by a Pro-Hero.
Long story short, she was accepted and entered Class 1-A. But that was where she met him, the infamous Katsuki Bakugo who wasn't on friendly terms. Taunting her "lame" and "useless" Quirk, one he never even saw in action before. Even with his taunts, it was clear a rivalry was forged between the two. It only grew worse when the Sports Festival arrived, throughout their trials and tribulations of villains, missions, punishments, and more, something began to... spark.
Not anger, rage, or even disdain, but rather... admiration. What will happen when Bakugo is suddenly ripped away by villains? When an old enslaver returns from their supposed death from the SWAT raid? When someone close to Y/n knows more than they're letting on?
