Monshiro High School
A weak-bodied punk rocker girl selected as the class representative for the culture festival alongside Shinagawa. She rarely came to class due to her condition until Shinagawa convinced her to come to class regularly. She soon developed some feelings for him, but finds out about the girl he likes after meeting Subaru Mito. She is the one who sets up Shinagawa into seeing Adachi without her glasses and braids on, and tells him that the person he is looking for is Adachi.
