Mimi Yoshioka

Ōtani's next door neighbor. She is in love with Ōtani, and brings him milk every day so he could reach her height, about the same as Risa's. Since Ōtani does not not have feelings toward her but he does have feelings for Risa, Mimi becomes jealous of her. She acts accordingly two-faced between them both-- acting sweet towards Ōtani, yet acting sour to Risa behind his back.
