Lapis Vindicta (Stone's Revenge)

Stone got lucky when he was brought into the world. He was born into one of Ramshackle's most wealthy families, and was able to be given almost anything he wanted at his request. At least, that's how you think it would have gone. Stone's parents always favored his older sister Avrille over him, often looking down on him for not being as perfect as they wanted him to be. And to make things even worse, Avrille was such a bitch. Always bullying Stone every chance she got, manipulated him, and even used him as a test subject for her various biological experiments. Needless to say, Stone hated all of this. He hated Avrille more than any other person in the world.
Eventually, Stone decided that enough was enough. One night, he snuck out of his family's mansion and ran off to live in the streets. He didn't care if he didn't have anything to his name, he just wanted to be as far away from his family as possible. And he swore on his life that he'd never go back. Ever. Nothing could convince him to return to that living hell of a place he used to call home.
At least, that's what he thought.
