O-Parts Hunter, Vol. 7 — Seishi Kishimoto

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?
