After becoming an adept when he was a kid, we learn Luke and his Father began to drift apart. Now they rarely see or speak to each other. Lenard worries that Luke will go berserk intentionally, and the other adepts wonder why Luke is feeling so depressed. During a summer cleaning spree, Luke is counseled by Shougo's father to trust in his allies a bit more often and he will really grow. Vyse is sent to Earth to claim the Dragon Bone as Dark Eagle. Thanks to the words of Shougo's father, Luke and Shark Bone are finally able to communicate. Dragon, Shark, and Rhino form a line and summon the Water Majin to help in their battle. With his power they defeat Dark Eagle. After seeing Luke's resolve, Leonard decides to head back to the lab and reveals that the elemental Majins are neutral to whom they help.
