Backstory:

Laramie seems like your typical high school girl, but she has a dark secret she hasn't even told her closest friends. She is an experiment that was with the very being that turned their world from joyful to a post apocalyptic wasteland.

You see, back when Laramie was younger, and went by the name of Aiden, and was the younger brother to Jose, who were sold by their gambling crazy parents to "government officials" in a project known as "Project Core."

Project Core was simply put, a hidden project that took kids from their parents, whether it be by kidnapping or being sold off by their families for crazy amounts of cash, and infuse them with deadly crystals that connected to a person's core, which were dubbed as Core Crystals, turning them into powerful warriors for the government.

When they scientists were working on Aiden and Jose, the cores that the used were a split core, as they broke a giant core crystal they found into multiple different parts. Aiden and Jose did manage to survive, both getting a few burn marks, but one of their peers, Nelson, was not so lucky.

The Core Crystal Shard that he obtained managed to manipulate and brainwash him, turning him into an ice cold killing psychopath, betraying some of the fellow test subjects and stealing their core crystals, all to become the ultimate being.

Nelson did manage to get to Aiden, and right as he was about to kill him, Jose managed to knock him  out, and go to her unconscious brother. It was at that moment, and seeing what had happened, that one of the scientists had a crazy idea.

Aiden then woke up, but realized that he was inside his sister's body, with a few touch differences. He also quickly realized that the scientists that did the operation on him were missing, the ones who were continuing Project Core, despite everything that happened, were dead, and that Nelson survived, causing a world wide apocalypse.

Aiden, taking up a new name, that being Laramie Martinez, begins travelling the world, looking for physical enhancements from the various labs across the world, destroying robots and taking what valuable resources they have and selling them, all while making sure that Nelson doesn't realize who he is.
