西野 愛莉紗

A girl with twin-tailed hair who is Rikuto's junior. She is lively, easygoing, and has a wide range of friendships with both men and women alike. She is a bitch and loves sex.

After school, she often goes out on the town with her bitchy friends, who have low chastity standards, and spends all day having sex.

She is especially interested in men who can make her cum a lot, and she likes a cock that is big enough and hard enough. She calls Rikuto "paisen" and she teases and seduces him in a bitchy way, as if she is trying to spoil him.
