Kaz:...hmm...well...perhaps you cannot be killed by mortal means. Perhaps you need a demon's hand.
Melody: you can try!
Kaz: Oh...but I can't. I'm not allowed to kill you, remember? But if we make another deal...
Melody: *sigh* bring it on.
Kaz strokes his chin
Kaz:...but I can't just make the deal with you for free. You're going to need to give me something else...something of value to you...
Melody: well, i still have organs, i can give one to you if you want!
Kaz:...hmm...how about your heart? ...That one usually works in a trade...
Melody: hmm, how about my brain?
Kaz: hmmm....well, you do seem to value that quite a bit. Alright. Your brain, and in return I send you to the afterlife. Do we have a deal?
He holds his hand out
Melody: *takes your hand* deal!
