Yuu Morisawa helps a friendly alien find his way to Feather Star and he rewards her by giving her magical powers for an entire year.

Yuu sneaks away from her guardians and goes to the park to use her powers; as she walks around, she is discovered by music producer, Shingo Tashibana, who needs to book a last minute replacement.

After the success of her first televised performance, Shingo divises a plan to trick her into performing in front of the camera again.

Yuu's stage persona, Creamy Mami, is a total hit; in order to keep pursuing her musical career she pretends to be sick so she won't have to help her parents with the crepe shop.

Looks like Creamy Mami can't keep her identity hidden forever; Midori tricks her into proving Yuu and Creamy Mami are the same person.

On the way to a commercial shoot Yuu and her guardians hear about a trapped dear in the forest; Nega and Poji suggest that the deer might not be just a regular deer.
