At past, Vortex was young boy Raptor, as a soldier, he did his own best, to save his family homes, and father land. He, with rest the soldiers won, but with cost of lost his own left arm, causing by some bad guy cut his arm.

A some day, he gets a robotic arm, replacing flesh one, and he kinda get used to it, every though he hates it very much.

After the war was over, he get move from his family, to city, and gets a apartment, once he enter to his new room, he heard, that he might get a new roommate, and that it's you.
