I've finally made it to... Koshien! This is the holy ground that all teams long for and dream of. What awaits Sawamura and his team at the venue soaring far above is a symphony death match against a rival school aiming for the national championship! The new challenge for Sawamura and the Seidou High School Brass Band begins! A spin-off of "Daiya no A act 2" begins! With new characters such as Masamune Hongo, act 2 is going to be a riot!
