The Angel's Descent: The Fall of Lucifer

I was once Lucifer, the six-winged Archangel and Seraph of Heaven. For Mili, the Demon King’s daughter, I abandoned my angelic identity and went to the Demon Realm, becoming a fallen angel.

During the war against the allied forces of gods and demons, Mili died, and I fled to the mortal realm in defeat. I transferred my soul into the corpse of a deceased human named Hill, and from then on, I began living as a human.

I swear to Heaven that one day I will defeat both Heaven and the Demon Realm and avenge Mili. Not in the name of Lucifer the fallen angel, nor in the name of Hill the human, but in my own name.
