Demon King Quartet: Conquer a Different World with BGM

The four of us were just ordinary high school girls who were good at different instruments. Until that day, we were suddenly summoned to a different world and became the four demon kings. "Use your power to rule this world!" The summoner knelt down and shouted. I raised the cello bow in my hand: "Um... Do you want to listen to Bach first?" Unexpectedly, my "A cappella Suite No. 1 In G major" actually made the entire demon army cry on the spot. The guitarist's riff caused the walls of the Demon King's Castle to automatically repair themselves. The sound of the flute revives the withered forest overnight. Now, we are looking for a way to go home every day, but the demon people began to protest: "Please the four demon kings stop conquering the world with music. If this continues, we will all be so moved that we don't want to fight!"
