Kero Kero Chime (ケロケロちゃいむ, Kerokero Chaimu, "Ribbit Chime")[1] is a manga written by Maguro Fujita.

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.

There were a minor number of survivors from the snake clan, but Mimori soon discovers a rival: Suu, the princess from the Land of Snakes, who had survived the war, and whose parents were also absorbed.

This princess begins an interest to Aoi, and is jealous of Mimori, at which she finds a sailor (whose true identity is a woman) and falls in love with her.
