Who Said There Were Only 4 Devil Kings

Satan, the Devil. The embodiment of sin and Evil. at least, that's how the Bible pictures him. Satan. A ranking given to the strongest devils in the underworld. What if they were both wrong. What if Satan was not actually a Devil, and he had kids known as Lucifer, Leviathan, Beelzebub, Asmodeus, and a fifth child that would watch from the shadows during the Great War. Much like their father, this child of Satan would not truly fall from God's grace, but he still aids his brethren from the shadows. But what if there was more, an elite force made of the embodiments of the 7 deadly sins, made to guard the child of Satan? this is the story of the grandson of the child of Satan. (Warning: extreme Rias bashing iminant, when she's present) I own nothing except my character and the direction the story is taking. (#28 in Lucifer)
