Jinguu Music Academy

Jinguu Music Academy is the name of the once former school that was shut down due to lack of enrollment, but later on was reopened by former student Hana Hazuki and was renamed Yuigaoka Girls' High School.

Background
Not much is known about the history about the school except it's been open since it was built back in the Meiji Era and was cherished by the students. Later on, the school started to experience the signs of dwindling enrollment numbers and was on the brink of closing. Desperate to save the school, student Hana Hazuki along with her friends (one would later on become the current director) formed a school idol group to try to save it. Unfortunately, it was for naught, as the school was officially closed down.
