Sarah Kazuno is the leader of Aqours's rival group, Saint Snow. She is one of Saint Snow's two members, the other being her younger sister, Leah. Sarah is a third year student at Seisen Girls' Academy. Her image color is sky blue.
While singing, Sarah is the lead vocalist. Sarah is also the lyricist and the composer of the songs for Saint Snow.
Sarah possesses an outgoing personality, usually speaking on behalf of both of Saint Snow's members in its exchanges with Aqours.
Despite her being the more hospitable of the Kazuno sisters, Sarah maintains her sense of combativeness through asserting control over conversations she engages in. Her competitiveness is also highlighted in her sole desire to win the Love Live!. She believes that, through reaching the same ends which A-RISE and µ's arrived at in the Love Live!, victory in the Love Live! would give her insight into the qualities that made the two idol groups.
Much like her younger sister, Sarah displays a high level of conviction for Saint Snow's cause. Despite complimenting Aqours for their performance at the Tokyo idol event, it is revealed through Leah's comments that Sarah belittled Aqours's performances for being child's play, and would rather they give up on winning the Love Live!.
Sarah carries herself with a sense of self-assurance as well, boasting of Saint Snow's performance before Aqours in the lead-up to their performance at the Tokyo idol event.
|In episode 7, Aqours were invited to perform at an event in Tokyo. At Kanda Shrine, Chika heard Sarah and Leah Kazuno singing “SELF CONTROL!!”. Although the two girls were strangers to Chika and the rest of Aqours, Sarah recognized them from their PV and asked if they were in Tokyo for the upcoming event. The Saint Snow members then left, leaving Aqours impressed with their acrobatics and singing skills.
The next day at the event location, the Aqours members were surprised to find out the girls they had met at Kanda Shrine were school idols, too. Sarah introduced herself, and the episode ended just as Saint Snow were to take the stage.
