Saki has shoulder length reddish-brown hair and gold eyes. She wears the school uniform.
Saki's primary concern is her popularity at school. She confronted Sakuta Azusagawa and told him to stop hanging out with her boyfriend Yuuma Kunimi, as she assumed Sakuta's status as a loner would lower Yuuma's reputation and hers as well.
Kunimi is the student Saki is currently dating. Although she shows affection towards Yuuma, Saki is quite protective of him and often clashes with Sakuta Azusagawa as a result. She and Yuuma got into a fight after Saki removed Sakuta from Yuuma's contact list, but they have since made up.
