She is a first year high school student at Sakuragaoka High School during Class 1-1's second year of schooling.
Being from a small town, Hiyori isn't quite used to city living and is very interested in what Tokyo offers. From initial media, she seems to be an optimistic girl with a somewhat naive personality, and gets lost very easily. She also doesn't seem to be culturally aware, given that she doesn't recognize the LIP×LIP duo or ASCANA despite them being popular singers, especially with girls her age.
