Kanou, Ryouko

加納涼子

Ryouko is a girl with a passion for painting; in her spare time, she is often seen drawing or painting. She is also Tsuyoshi's neighbor in the apartment complex where they live.
Her story appears in episode 4, where she asks Tsuyoshi to pose as her model for a drawing. Initially, Tsuyoshi models in her apartment, but later, to complete the work, she asks him to pose for her again at school. This leads them into a strange situation later on.
She makes only a cameo appearance in the OVA intro, where she is, as you might guess, making a drawing.
