Description
"No one said that demon hearts were supposed to be pretty, but you weren't expecting this mushy, fleshy bag of vileness. Heavy and wet, the organ still beats, and even though it is stuffed away with your belongings, you hear the dreadful thub-dub. Every now and then you must check to make sure that it has not bounced out of your pack."
