Seven Mortal Sins

Trama

Lucifer, a proud archangel and former leader of the Seven Heavenly Virtues, is cast out of Heaven for disobeying God. During her fall, she briefly encounters a high school girl named Maria Totsuka on Earth before continuing her descent into Hell. There, she meets Leviathan, an aspiring Demon Lord. Together, they attempt to challenge the Seven Deadly Sins, the rulers of Hell led by Belial. However, the Seven Sins overpower Lucifer, sealing her divine abilities with a Garb of Punishment and transforming her into a Demon Lord.
