Lucifer

The four winged Demon Lord of Hell and [Michael's](https://anilist.co/character/4556/Michael) twin brother. He was born with the purpose of becoming the Prince of Darkness and ruler of the demons, despite his loyalty to God. He stages a rebellion to get revenge against God for forcing him into the role of the Demon Lord. While seeming cold, calculating, and pure evil, Lucifer struggles to resist his destiny as ordained by God. ~!God eventually sealed his soul into the seven bladed sword Nanatsusaya, which became Alexiel's sword.!~
