Similar to Dragon Slayer Magic and God Slayer Magic, you choose one element (fire, water, ice, lightning, etc.) to become your element and become immune to it. This immunity can be overpowered, and you are able to consume your element to regain your strength and get a temporary boost. You are able to gain information about any demon or devil you see by observing them for a couple of seconds. You are able to do the same with curses and curse magic. You're also capable of killing demons by using your magic. But all of this power comes at a cost. You will begin to transform into a demon. If you're able to master Devil Slayer magic, you're able to halt the demonization and allow you to call upon a transformation to boost your physical strength and speed.
