O-Parts Hunter, Vol. 12

Ruby's dream: to become a famous treasure hunter. Jio's dream: to rule the world!

In a not too distant future, mankind battles over O-Parts, powerful relics from an ancient civilization. Jio is a young boy with a tragic past who only trusts one thing in the world: money. Little does he suspect that he is also a very powerful O-Parts Tactician (O.P.T.), and inside him sleeps a demon of incredible ferocity. With his partner, Ruby, Jio embarks on a dangerous quest to acquire as many O-Parts as he can.

Our heroes head off to save Ruby but are thwarted by two monstrous guards! Will Ball be able to hold them off while Jio charges to Ruby's rescue? Or will Jio fail his toughest test yet when he's forced to face his own true nature?
