Yuu Kashima is a female character in the Gekkan Shoujo Nozaki-kun anime and manga series. She is friends with Chiyo Sakura, Umetarou Nozaki, Yuzuki Seo, Hirotaka Wakamatsu, Mikoto Mikoshiba, and Masayuki Hori, and the elder sister of Rei Kashima, who attends The Ladies Academy in middle school. Her birthday is February 24th. She has short black hair that reaches below her waist, brown eyes, and several scars on her body. She wears a pink tank top with white stripes and blue shorts with white stripes that cover her legs and feet. She also wears purple wristbands and orange sneakers with no socks. Yuu was born in Tokyo but moved to Osaka when she was young. She has been living with her parents since coming to Japan and can speak Japanese well but sometimes mixes up some words due to her mother speaking too much at home. She has a younger brother named Rei who goes to the same school as Chiyo. When she meets Nozaki family again during the Christmas holidays, she learns that his father died during her absence. This makes her feel guilty and she decides not to see him for a while until he asks her out again. They start dating soon after and plan to get married after graduating from high school. In the last episode of the series, it is revealed that Yuu is pregnant with Nozaki's child.
