In the eastern sea, there is a beautiful and spiritual island called "Floating Light Island". Three hundred years ago, many monsters appeared on Floating Light Island. The cat god "Lan" cast a spell under an ancient tree on the mountain to get rid of them. In order to worship the cat god, the islanders built the "Floating Light Shrine" under the ancient tree. Since then, the island has been protected by a barrier, and monsters rarely appear. The kitten with an obsession has the opportunity to transform into a cat spirit with human form, cat ears and cat tail.
