Kei Enomoto

One of Ayumi's friends, Kei is apparently very popular with guys due to her "mature" face. However, she sees the attention she receives as a hassle, and believes confessions of love are just a chore if the feeling isn't mutual. She openly admits that looks are a major factor in choosing a relationship, but carries a love-hate (mostly hate) relationship with Kusuda. She is in the same grade as Ayumi.
