O-Parts Hunter, Volume 7 (O-Parts Hunter #25-28)

Now that peace has returned to Entotsu City, Jio, Ruby and Ball strike out for the Dastom Ruins where they are told to search for a man named Wick - but the revelations Wick is about to share with them will be anything but easy to swallow. Is it true that O-Parts are originally from another planet far, far away? And is Jio now strong enough to survive his next run-in with the ruthless Zenom Syndicate?
