He's sent to an alternate realm where there exists a kingdom of frogs in order to locate the princess, whose mission it is to lift the curse bestowed upon Aoi. However, the princess discovers that she lacks the knowledge necessary to break the spell. Consequently, they embark on a quest to discover the enchantment that will restore Aoi to his human form. During their journey, they encounter numerous fascinating creatures, face various perils, and forge new friendships.
