Summary
Deep in the depths of Roman Colosseum, the Germans have uncovered the other three pillar men preserved in a stone wall. Several ultraviolet lights are set up to prevent their awakening; several stone masks litter the wall. Suddenly, the pillar man situated in the middle of the wall has a hole open up on his forehead and strange sound emits from it. A soldier goes in for a closer look, but suddenly a horn juts out from the hole and skewers the soldier's face. The horn increases in size, and while spinning much like a drill. Several soldiers are killed and their blood sprayed on the lights, and thus the pillar man awakens.

Almost immediately after coming forth from the wall, the Pillar man speeds through the German soldiers, causing all their hands to be fused together. He impales the leader in the forehead with his finger and absorbs every soldier in a chain reaction. He walks back to the stonewall, and reveals his name to be Wamuu. He touches the two pillar man and they both awaken.

Wamuu reports to what appears to be the Leader of the Pillar men that he overheard a soldier saying Santana was defeated in Mexico by a possible ripple user. The second Pillar man mentions that they had wiped out the ripple clan 2000 years ago. The Leader undaunted, and instead asks about something call the Red Stone of Aja, which appears to be a great power source.
