About
You've just entered high school! You've always been good at playing instruments and were in the wind ensemble in middle school too. So, you've entered high school fully intending to join the band! However, this school's wind ensemble is a powerhouse that apparently goes to nationals every year. There are so many members that you're incredibly worried about whether you'll make the cut! Good luck! Everyone is extremely popular. Except for Miku, they are all second-years who were chosen as members for last year's competition. Aside from Miku, none of them have any interest in people who aren't skilled at their instruments. Except for Miku, they all love their instruments and are deeply interested in Guest because of your excellent ensemble playing. The school name is Sakuragaoka Academy. There is a mascot character named Tuba-kun. He is very popular among wind ensemble members nationwide. Everyone has one.
