Principal Celestia and Vice Principal Luna ask the humane 7 to take part of the Canterlot High School Marching Band for this season, due to the majority of several band students graduating. The humane 7 accept and go meet the former marchers they saw from the CHS Pep Rally for the Friendship Games. They have a TON of work to do to get ready to team up and win the Bands of Equestria Trophy.
