Ayumi Arihara

Height: 152cm (4'9")

A second-year middle school second year, Ayumi is one day asked out by Misao Zaitsu. Though she claimed she would accept any offer, she is consistently unsettled by Zaitsu's monstrous appearance; however, she shows she can be somewhat caring as well as crafty. She is the second fastest runner in her class.

She shares a strong resemblance to Chinami Hashimoto, a character from another of Kawashita's work, Ichigo 100%.
