Kero Kero Chime - 2nd Opening

Kero Kero Chime (ケロケロちゃいむ, Kero Kero Chime?) is a manga written by Maguro Fujita. A 30-episode anime series of the same title is based off of the manga.

Aoi, a normal school boy, is cursed by a wizard named Makaeru from the Land of Frogs, who tells him, to derive the curse, he is to find Mimori, who is later discovered 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, and as foretold, Aoi asks in vain if she knew about the curse. However, Mimori remembers her brother's saying as he handed her the Book of Magic before he disappeared into an adventure: 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 realises that his quest now is to find the missing pages of the Book of Magic lest one of the pages contain the cure for the curse. When Mimori comes with him, the quest becomes ever more exciting.
