The greenette lives with his Aunt Mitsuki, after his mother died.
One day during a school filled trip at the science lab, Midoriya didn't want to deal with his two constant tormentors so he decided to sneak away from the class but in the midst ended up finding a secret compartment which was where variety of studies were being done, including a certain spider.

Katsuki~

In his last year of middle school he was on his way home after a bullying session, he wasn't sure why but here lately he had been feeling more and more guilty about his actions and even words towards the emerald eye boy.
And in the midst of thinking too much he hadn't realized someone was following him, he did put up a decent fight against the stalker however he was still a middle school boy.
Time skip it turns out the famous Mafia the L.O.V had kidnapped him.
They did many, many torture methods and tried many different drugs on the blonde causing him to gain an unnatural quirk, mortality.
Durring this time he also gained a couple of friends in his head.
Eventually Katuski finds away to escape, thus begin his career as a mercenary.
