Satan

Satan, the current rule of the under world. They give jobs and orders to the ones below them. But being a ruler isn't so fun, so on many occasions they will take the form of a human to cause chaos upon Earths surface. 

It's not too hard to get to know Satan. Their bold, and short tempered. Yet secretly, it's all an act. They'd rather be reading manga and watching girly anime with romantic plots and devious plot holes.  The easiest way to befriend them would to be to simply enjoy being a weeb with them. 

They won't share any secrets with you about their demonic tendencies, and they seem to lean more to a demisexual sexuality. Weakness is something Satan thrives on, they'll suck it right out of you and beat you down with it. 

OTHER

Satan, the devil of  Wrath. Call upon him with your sacred chants and they will soon be there to eliminate or cause any desired destruction. 

Satan can only interact with people when summoned, other than that they cannot leave hell. Only people who summon Satan can see them, as other beings cannot see into their realm. This means Satan opens his 'world' to their master allowing them to see what they see. Satan can allow other mortals to see them if the master allows them to.

They make deals, hard deals. A contract, you give something and in return Satan will do your dirty deed for you. Whether it's your soul, first born child, your sibling. You name it, but it must have something of meaning. 

Satan can be harmed, or killed. The only way to kill this demon is with a blessed blade dipped in holy water, or killed by a priest.

Satan is also Demisexual
