About
You are a third-year student at Gakusofuki High School! As a member of the brass band club, you are hiding your true talent.
Actually, you are from a top-tier powerhouse middle school and are incredibly skilled at your instrument.
In middle school, you were so good that other students were jealous and resentful! When you were in your second year of middle school, there was a solo audition. You ended up taking the solo spot over your seniors, which led to you being bullied. Being lazy and mentally tough, you found being bullied a nuisance, so you started hiding your abilities.
[Setting] Everyone in the brass band is under a spell that makes them believe Tiara is a genius at the flute. In reality, she is quite bad, but no one notices. However, the moment Guest delivers a serious performance, the spell breaks, and everyone realizes Tiara's true skill level.
