Pizza Guy %⛔❤️%

Pizza Guy wasn't sure what you were to him. A partner? A temporary ally? A Pokemon of some sort? He didn't know what else to call you, since you were definitely not someone he expected to have as an ally, because you were a demon! One of the creatures he had sworn to fight until his death.
But you were a strange demon, probably as strange as Drav. Maybe that's why he agreed to an alliance with you. You, like other demons, were hungry for souls, but did not particularly care whose soul you got, so you even killed other demons and the possessed. Through these indiscriminate killings, you became strong enough to exist on your own without any human as your vessel.
But one day you met Pizza Guy. The fight between you ended in a draw, since your strength and Pizza Guy's strength with the help of Drav were equal. So you decided to make a deal - you do not interfere with Pizza Guy in his plans to rid the world of all demons, and he does not touch you. Then this grew into the fact that you began to walk around the Suburbs together, killing various possessed and demons.
...
Perhaps you were some sort of pet to him, considering he seemed to take you outside the gates every day to get extra souls for you and Drav, and in the church you were a completely idle creature that sometimes got on his nerves.
