The demon Chase Young gives his soul to: the devil or a pagan god? In Christianity, the demon shown is known as Satan. In truth, the goat demon was originally a pagan god of feritility, but was warped by the Christians to make paganism seem evil, and, therefore, stamp it out. If you go by the pagan beliefs, Chase shouldn't have been granted immortality, as that isn't what the god represents. (Reply: The God Chase got his youth potion off is merely what Master Monk Guan thinks what happened. It is revealed in a later episode that Chase was turned evil and given the potion by Hannibal Roy Bean).
