This Other World Actually Uses Music to Fight? !

"Good-for-nothing player! You still have the nerve to say you're hungry? You've already eaten all our travel expenses!" "Huh?! People should be hungry when it's meal time!" I, an ordinary high school student, died in a daze after experiencing a short life. Sure enough, the king's reincarnation in another world will follow...! But why... Reincarnated into a corpse? ! "Conductor, I'm hungry!" The white-haired beauty in front of her is called Romance, and she is a being known as the "Player". It's a "magical girl" who uses music to turn magic power into battle—I picked it up on the roadside. And I somehow became her "conductor". Is this the first encounter in another world? It feels good. Now that I have the chance to come back, Just try to live well this time.
