Yuri Kuma Arashi

Every night, 16-year-old Kureha Tsubaki has strange dreams involving lilies, storms, and... being rescued by her classmate Ginko as an alien bear princess?!

At school, Kureha's unassuming personality and looks render her practically invisible. Sometimes, it feels like no one notices her at all, until cute and outgoing transfer student Ginko asks Kureha to be her friend. With Ginko's encouragement and protection, Kureha starts to come out of her shell and realizes that, whether or not her new classmate really is a bear, her feelings toward Ginko might be stronger than friendship after all.
