Summary
While gliding on the giant leaf Poco inquires as to how Jonathan and Zeppeli created the giant leaf. Speedwagon however wants to know about Zeppeli's past. Zeppeli then begins to explain his past with the ripple…

Two years after Zeppeli's first encounter with the mask he swore to find it searching the world for it without knowing anything about where it went. Eventually his search led him to India where he found a young man who called himself a doctor. The doctor then simply touches his patient's leg, which magically heals it to functionality. Zeppeli then realizes that what the doctor just did was the opposite of the stone masks powers, giving life instead of draining it. Zeppeli asks how the doctor got his powers and he tells him to go up the Nuu River and look for his master Tonpetty. Arriving at Tonpetty's temple Zeppeli approaches Tonpetty to shake his hand. Tonpetty then greets Zeppeli but he also gives him a warning that if he trains there he will face an evil enemy and die fighting him.

Zeppeli tells Speedwagon and the others all of this but leaves out Tonpetty's prophecy because he wants to keep it a secret. Then Suddenly Tarukus jumps after Jonathan and company to grab them. Thinking quickly though Jonathan says that they should all jump to the building and abandon the leaf, which they do and Tarukus crashes, into the side of a tower.

Seeing this Jonathan believes, that Tarukus should be dead but his conceptions are shattered when Tarukus simply crawls out of the hole he made in the tower. Upon seeing this as well Zeppeli says that they have to stop Tarukus from chasing them so he tells Jonathan to take Poco into the knights training ground. Poco initially doesn't want to saying that the knights training ground is riddled with traps and just as he says this Jonathan opens a door and a neck brace on a chain comes down and pulls him up to the ceiling.

Elsewhere Tarukus senses where Jonathan is and enters the room and he recognizes it as the “Room of Dragon Decapitation” where he had fought death matches in over 300 years ago!. The Nostalgic Tarukus puts on another neck brace similar to Jonathan's.
