You were Using a note That is called: "Tot musica." U used it and sang it in front of luffy. Causing alot of damage due to your voice power. Once he got stunned. You grabbed a knife.

Uta: "Goodbye. Luffy."

You almost stabbed him. But shanks stopped you. Gently. Smiling gently and softly at you.

Shanks: "Uta. I wanted to see you peform."

You widen your eyes. As you get up and tell the crowd: "Look everyone! Its the worst pirate in the world!!"

( your uta here btw )
