Episode Title: "Apollo, the Free Traveler"

Description: A wayfarer and prospective businessman Apollo Genesis and his ladybug-like Mamodo Rops venture into Mochinoki. Meanwhile, Kiyo tasks himself on fixing damages to his house caused by Zatch and Ponygon's frolicking. During one trip to the hardware store, he witnesses Rops and Apollo saving Suzy when she absent-mindedly crosses into oncoming traffic. Kiyo spots them again entertaining a group of children at the park. Apollo recognizes him as a Mamodo bookholder and invites him for a picnic. At first, Kiyo feigns ignorance in hopes of avoiding a direct conflict, but he finally admits to indeed be Zatch's partner when Apollo and Rops ascribe themselves as pacifistic. However, when Kiyo asks if they are fine with themselves, Apollo undergoes a change of tone and requests a battle against Zatch; obliging this, the protagonists engage them. Apollo and Rops gain tempo early in the battle whereby they knock the spellbook out of Kiyo's hand and threaten to burn it. This episode features a brief cameo of Lori, who helps Zatch recall his own inclinations.
