She does everything to ruin Momo's life. Her fair features (pale skin, brown hair) serve as a contrast for Momo; her "innocent" appearance belies her scheming, manipulative nature. She is the one who spreads malicious gossip about her - Something Momo knows, but has trouble dealing with, as people are more apt to believe in Sae than the 'airheaded ganguro girl'. She often uses the gossip to make people dislike Momo, as a result of her own jealousy and insecurity. One of the rumors she spreads says that she is dating Touji, and that Momo is trying to steal him from her when it is actually the other way around. She really is mean and doesn't care for Momo and is neither her "real" friend. All she wants is popularity in school, a hated outcast named Momo and Touji all for herself. She will stop at nothing to complete this task. Later she dates a male model to get revenge on Momo, the nastiest scheme she has ever plotted. She basically ruins Momo's and Toji's lives. 

Peach Girl is about an average high school girl, Momo Adachi, who everyone thinks is a beach bunny / slut because of her tanned skin. The actual reason she is so tanned is because she was on the swim team and tans very easily. She likes a boy, Toji, who she heard only likes non-tanned girls. This causes her to question who she is and have low self esteem. She spends a lot of time trying to remake herself into the girl she believes he wants. However, she has a friend, Sae, who likes to go behind Momo's back and make her life terrible, mostly by trying to take Toji away from her. All the while there's another boy, Kairi, who is in love with Momo.
