Rio Nakamura - 中村莉桜

She is a student in Korosensei's Class 3-E of Kunugigaoka Junior High School. She was a former elementary school genius but felt lonely and longed to be normal. When she got to middle school, she began shirking off her studies which landed her in Class 3-E. She loves teasing the other students in her class (sometimes together with Karma Akabane)
