Ayu Kawashima

One of Ichikawa's friends and classmates. Kawashima has a bad reputation for her openly perverted nature. She is regularly seen reading porn in school, and is not hiding her libido, banging Urisugi each time she could afford it. On the other hand, she is always there when her friends or acquaintances need help. She also has the best grades out of the main trio, and Momona and Hanako often ask her for notes, and can give surprisingly insightful commentary on the nature of erotic material when asked.
