Seven Mortal Sins

Lucifer, an Archangel who once led the Seven Heavenly Virtues, is cast out of Heaven after defying the Lord’s will. Her fall is briefly interrupted when she crashes through the roof of a high school church, where she’s seen by the quiet student Maria Totsuka, before continuing her descent into Hell.

In the underworld, Lucifer is discovered by Leviathan, an aspiring Demon Lord and devoted admirer. Together they challenge the Seven Sins—Hell’s ruling authorities under Belial—but Lucifer is defeated, her divine power sealed by the Garb of Punishment that forces her into the form of a Demon Lord. Driven by vengeance, she returns to Earth with Leviathan at her side, binds Maria as her immortal servant, and begins a campaign to subdue the Seven Sins and break the curse placed upon her.
