Seven Mortal Sins - S01

Lucifer, an Archangel and former head of the Seven Heavenly Virtues, is cast out of Heaven after rebelling against the Lord's will. As she falls from the sky, she is stopped halfway between Heaven and Hell when she crashes through the roof of a high school church. Though Maria Totsuka, a soft-spoken student at the academy, sees her, Lucifer quickly resumes her plunge into the depths of Hell. Soon after arriving, Lucifer is found by Leviathan, an aspiring Demon Lord and devoted fan. The two decide to overthrow the Seven Sins, the rulers of Hell under Belial's leadership. But even with their powers combined, the Seven Sins manage to drive Lucifer back and seal her divine powers by placing a Garb of Punishment on her body, turning her into a Demon Lord. Seeking revenge and accompanied by Leviathan, Lucifer returns to Earth, where she forces Maria to become her immortal slave. Together with her new accomplices, Lucifer sets out to subdue the Seven Sins so she can break free of the curse her Garb has placed on her.
