平通 良子

Ryoshiko is Jun's girlfriend and a friend of Karin.  Later, she becomes the friend of Mitsu, Atsu, Yume, Yurari and Seiji.

She and Jun know each other from the middle school but they did not talk to each other before. Jun only noticed her in high school during a painting class because he had been hypnotized by her concentration. He had asked her to go out with him soon after.

She is shy and does not dare to impose herself during conversations. It is often Jun who put it forward by exposing the countless quality she has.

She idolizes and has an incredible admiration for Yoshino-sensei, like all the rest of the students and professors of the school.
