Siffleur

What your character smells like: He is not human at all, in fact this boy is being held together by magic. Dark magic. The smell of darkness lingers on him for someone who can pick up that sort of thing. He probably smells like something that shouldn't be eaten unless someone is feeling particularly adventurous.
What parts are edible: All of him, why not. It's debatable if he has a heart.
How graphic are you prepared for tags to be (from G to NC17): Whatever you want.
Do you want your character to be eaten alive, or killed first: Dealer's choice.

Also attacking him is a good way to get wet as he has water magic. Have fun!
