Ame and Hare's journey of wind

Sunny has a peculiar ability: wherever he is, there’s always clear skies and sunshine. One day on his travels he comes across the girl Raine, whose ability is the exact opposite of his. This is the whimsical tale of Sunny, Raine, and their feline companion Polkadot as they journey to find the floating island Final Rest and return home a special little sapling. And maybe, along the way, find a place where they belong.
