Intransigent magistrate Viola Orlando is targeted by her rivals who set her twin sister Rosa — a high-class prostitute and pornographic photo-novel star — up to impersonate Viola and demolish her reputation. To complicate things even further, Viola is torn between enforcing the law or giving up her seat on the bench to marry her childhood friend.

The plot involves the coming of Lucifer to the Sanctuary, where his underlings systematically dispose of the surviving Gold Saints. Athena goes to Lucifer to ask for peace, placing herself in peril. The Bronze Saints must then come to her rescue, destroying Lucifer's Fallen Angels (Seima Tenshi in Japanese) in the process.
