Demonic Righteousness

Centuries Ago the rebellion lead by the former archangel Lucifer was banished from the heavens and sent to Hell, his followers along with him. Now as the new Demon King, Lucifer can finally take his rightful place in paradise. Lucifer created an army of demons at his command, so he can one day take over all four realms. Lucifer declared war against God. Thus the Great Holy war in Heaven has begun. They battled for centuries to claim paradise; Lucifer wanted to kill Michael himself and rule over the heavens to show God that who is truly worthy of the throne, cause ye who rules over heaven, rules all the realms. He lost the war due to the loss of his angel wings, now there had been no demonic activity for 15,000 years until The Seven Deadly Sins released Lucifer from his eternal chains with the help of a Fallen Angel. Now it is up to the hands of Archdemon Drogon, would he defeat Lucifer alone or would he be forever be trapped with the Sin of Wrath?
