In the not too distant future, mankind battles over O-Parts, relics from an ancient civilization. It takes a special kind of person to unlock the full potential of these remnants from the past, and a unique breed of humans known as O.P.T.s (or O-Parts Tacticians) become a force to be reckoned with. Unfortunately, O-Parts can be used for good or evil purposes.
As the battle between Shuri and Jin intensifies, Anna and Kite remain imprisoned. Meanwhile, Jio and Ball prepare for their battle. Jio is an amazing O.P.T., and Ball is stronger than anyone expected...but their opponent is fierce. Will Jio have to rely on the dark power inside him in order to win?
