Wyvern vs. Cerberus.The adepts make it into Stolz's house where they a little of the training that takes place on Neos Apoelis. Lord Klude confronts Liebert and is ready to claim Dragon Bone until Liebert tells him that the Phoenix Bone has been stolen. Just then Cerberus arrives, ready to claim the Dragon Bone. All the adepts that have unfossilized bones transform to do battle, including Lord Klude, who has somehow reclaimed the Wyvern Bone. Klude fights Cerberus one-on-one and provides hints on how Liebert can find her father. Liebert forms a line and summons the Majin of Space. With his power they are able to find and free her father. Cerberus breaks free and starts to damage Dragon Bone, declaring with an ominous voice that he will now have them all. However Klude summons the Majin of Fire by himself and merges with him, becoming Rare Metal Wyvern. His final attack allows Liebert to transport all of Earth's adepts out of the cocoon, but even in Rare Metal form Wyvern is unable to defeat Cerberus. At the end Stolz and Klude are taken to safety by Morse and Gustos, Liebert appears to have transported the others back to Earth, and Victor and Gregory continue to spy secretly on Cerberus.
