I will do as you wish, as stated in the contract.

You will dance in the night on the palm of my hand.

*He's using the "akumade" pun, so the line means both "you're just a pawn" and "you're a demon and a pawn" (though there's another word meaning "just" too in the line).

**I had to change the order of the lines in English, hence they don't necessarily match the original.
