Kero Kero Chime (ケロケロちゃいむ) is a manga written by Maguro Fujita. A 30-episode anime series based on the manga was produced by NAS and TV Tokyo and animated by Studio Comet.

Plot
Aoi, a normal school boy, is cursed by a wizard named Makaeru from the Land of Frogs, who tells him that if he wants to remove the curse he is to find Mimori, who is later discovered to be the sister of Makaeru. The curse causes Aoi to transform into a frog whenever he is wet, changing back into a human when he dries off. Makaeru then casts Aoi into the Land of Frogs, where he meets Mimori, the princess of the land. Aoi asks if she knew about the curse. However, Mimori remembers her brother's saying as he handed her the Book of Magic before he disappeared: "This book enables the frog people like us to use magic. If you find that there are some pages missing, then it is your duty to find it."

Aoi then realizes that his quest is to find the missing pages of the Book of Magic, hoping that the pages will contain the cure for the curse.
