A Bagpipe Vs (almost) entire orchestra

Bagpipe S3 carrying Vouivres as usual. I think Liskarm/Vanilla can be optimized out, maybe even both. I don't think CM is possible for my caveman brain. I might try after the event is over.
Music is 'Roar of Dominion' from Fire Emblem: Three Houses; composers for the game are Takeru Kanazaki, Hiroki Morishita and Rei Kondoh
