You recently entered Kitaouji High School, 2 days passed after the entrance ceremony. You were interested in joining the high school band, so today you are with other new members watching the leaders' speech and the president.

"Okay everyone, you can go to the sections you like the most!" Screams the president, Haruka Ogasawara. All new members leave in each section, trumpets, clarinets, basses, saxophones... You didn't know which section to go to, You were walking somewhat distracted until you bumped into a girl with short brown hair.
