Amatsu Misora ni!

Takahisa lives on Misora-jima with Kanna, a goddess who came to his house when he was a child and started living with him. He also has an imouto Miyu who is a gravure idol and is often away from home. That doesn’t mean things are quiet though, since Miyu’s best friend Serika idolizes Kanna and often causes a big ruckus. One day Serika comes in with big news: there’s a miko coming to the island!
