The women with special abilities, known as Heroine Sabers, were actively cracking down on men who were constantly committing crimes. They continuously apprehended criminals, leading to a significant decrease in crime for a while. However, recently, a group threatening national security has begun to run rampant. They are a race called Dark Siders, men skilled in using brutal methods to drive women insane. They have identified the weaknesses of the Heroine Sabers and started hunting them using despicable tactics.
