Jinguu Music Academy

Jinguu Music Academy is a 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 cheeished by the students. Later on, the school started to experience the drawling student enrollment and was on the brink of closing. Desperate to save the school, student Hana Hazuki along with her friends (the current director) formed an school idol group to try to save it. Unfortunately, it was for nothing, as the school was officially closed down.
