Kingdom of Knuffel

You are (moon)light.

You are earth

You are water.

Earth, obviously!

Hmmmmm

I'm gonna go light-- the spotlight, because you're clearly a popstar :D

I think you're fire (it's definitely the yukata talking ^^)

Could you be anything but water?

A tricky one but I think you're darkness.

I think you're light.

Sound or Music really ought to be an Element.
What would it correspond to the most?
Air, as the primary medium through which it promulgates?
Okay, you're Air.
