Long time companion of the Mist Fairy, the Rain Fairy lives high over the clouds.
She's rather lazy actually and so, this little fairy spends a big part of her day sleeping on the soft surface of the clouds. But if a loud thunder clap wakes her up, she startles so much that she's shaking all the raindrops out of the clouds.
So, if you want to stay dry, you'd better not make too much noise!
