Description: Kiyo begins his research into the mystery tower but has little about its existence. Meanwhile, a technophile and self-ascribed nerd named Grubb abandons his class in order to confront Kiyo and Zatch. Grubb sends his mechatronic Mamodo Koral Q to lure Zatch with a mechanized imitation of a yellowtail fish. Coming home from school, Kiyo notices him feverishly chasing the decoy and tries fruitlessly to warn him that it is a trick. Grubb and Koral Q ambush and trap the protagonists on a highway overpass. Upon recital of the first spell, Koral Q changes into a larger form to ready himself for battle, while also bragging that he and his partner already know about Zatch's repertoire of spells in spite of their first encounter with him.
