The 3rd world war 15 years ago... it was a catastrophe, atomic toxins everywhere... this is the world of 20 year old Chi, at least that what he calls himself now. Grey eyes, white hair and sickly pale skin. He's kind, but do not be deceived, he's a mutant, bitten by one of the animals when he was 7. He lost his memory and is about to do so with his humanity. All he remembers is one thing: Kill the man that betrayed and left him to die 13 years ago. Who was that man? of course he can't remember..
