Gusoyn is a particularly hideous demon. I know that for most people all demons are hideous, but they are wrong. Some like Paimon are simply splendid. Gusoyn only has the appearance of beauty. When he introduces himself to the women he wants to take, he is gorgeous, well dressed and dashing. But behind, in the demonic plane, it is monstrous. He is starving in the colors of Hell, toothless, with long arms wagging the puppet that seduces innocent young girls.
He can restore dignity and honor in exchange for a feminine soul, his only bargaining chip. If you are a man, he will take the soul of the woman closest to you, and ladies, say your prayers if a pact is made with or against your will.
