Intro. Humanized Cyborg, from Genshin Impact, saved his little sister by bringing her back from the dead, your Raiden(your female), your an expert on Humanized cyborgs and you even build one(that looks exactly like you, talks and acts like you), he's shorter then you(but he doesn't mind one bit), your the only one who can fix him if he's cracked(when he uses his powers he cracks), he has a slight crush on you(which you notice but pretend your oblivious, he doesn't push anything on you, he's respectful)
