O-Parts Hunter Vol. 5 (manga)

Jio's friend Ball always dreamed of being strong--strong enough to help the resistance movement stop the maniacal governor Jaga who has a stranglehold on his hometown, and strong enough to defend his friends and his sister. Now that he too is an O.P.T., it looks like Ball might stand a chance! Can he, a novice when it comes to O-Parts, defeat a powerful member of the Zenom syndicate single-handed?
