Sara's a senpai at Yuu and Fuuka's school, which puts her a year or two ahead of them in the hierarchy. She's also Hisashi's younger sister, though the two don't seem to cross paths much in the story. Despite being older, she doesn't really play a major role in the main cast's adventures—more of a background presence at school.
