Yuri Bear Storm

Every night, 16-year-old Kureha has a strange dream involving lilies, storms, and her classmate Ginko as a bear. 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.
