A 2nd-year student in Class 2-C at Kunahama Academy. She transferred from the mainland at the start of the story and became classmates with Masaya and the others. She is curious and hardworking, always speaking in polite language. On the other hand, she is a bit airheaded, losing her house keys immediately after arriving and getting distracted by romantic daydreams even before a match, much to the exasperation of those around her. Originally unable to fly, she learned how to use Grav-Shoes from the protagonist and subsequently blossomed into a natural genius at the sport.

Her family runs an udon shop called "Mashiro Udon." She isn't very good at studying and has famously failed tests, requiring makeup exams. Conversely, she is quite a hardcore gamer. She usually doesn't wear them for a specific reason, but she wears glasses during class due to nearsightedness (this poor vision eventually led to her switching styles from Fighter to Speeder).
