Tsubasa is a third year student at UTX High School. Together with Anju Yuki and Erena Todo, they formed the school idol group A-RISE, which rose to popularity. 

Tsubasa is humble yet competitive. Despite A-RISE's popularity, she admits that she wasn't interested in it nor does she seemed concerned losing the popularity their group has achieved. She never seems to look down on A-RISE's opponents, especially μ's whom she praises and respects. Though she admires them, she says that A-RISE won't lose.
