Saki has shoulder length reddish-brown hair and gold eyes. She wears the school uniform.
Saki's primary concern is her popularity at school, shown when she confronted Sakuta Azusagawa and told him to stop hanging out with her boyfriend Yuuma Kunimi, as Saki assumed Sakuta's status as a loner would lower Yuuma's reputation and hers as well. In later episodes, it's revealed that she has a sister that she's often compared to by her parents, implying Saki developed a low self-esteem because of it, which can explain why she is very protective of Kunimi's image and her own, because her own self-image in her eyes is already fragile.
While Yuuma Kunimi was walking with Sakuta Azusagawa towards the school, she approached them and took Yuuma with her, giving a bad eye to Sakuta. Sometime later, Saki warned Sakuta to stop hanging out with Yuuma, explaining that Sakuta's involvement with the Hospitalization Incident would tarnish Yuuma's popularity and thus her own as well. In response, Sakuta asked why Saki was irritated and if she was on her period, which managed to drive her away.
Saki approached Sakuta again, reminding him to stay away from Yuuma and then asked him about Rio Futaba and what was she to Yuuma, but Sakuta told her to speak with Yuuma and then asked her if she was constipated, making her angry again and leaving while wishing him to die.
One day as Mai and Nodoka swapped bodies, Sakuta needed some advice from someone with big sister. Yuuma then called Saki as she had one and Sakuta asked her if she liked or hated her sister. Saki told him it was neither, but she didn't like how her mother was saying she should take an example of her big sister.
Kunimi is Saki's current boyfriend. She shows affection towards him, but is also quite protective of him and she often clashes with Sakuta Azusagawa as a result. They got into a fight after Saki removed Sakuta from Yuuma's contact list, but they have since made up.
Saki is shown to be slightly hostile towards Sakuta as she concerns about the possibility that his relationship with Yuuma will hurt the latter’s reputation. Saki generally tends to avoid him for his involvement in the "Hospitalization Incident". Conversations between the two often end up with Saki disgusted and storming off because of Sakuta giving sudden and obscene retorts.
