This extreme and polarizing premise sets the tone for the series, which explores themes of justice, revenge, and societal power dynamics.

The narrative unfolds through episodic cases, each focusing on a different woman seeking Rei's help. These women are often victims of abuse, exploitation, or betrayal by men in positions of authority or trust.

The series does not shy away from graphic depictions of sexual violence, which has contributed to its contentious reputation.

Supporting characters include the women Rei assists, each with their own stories of victimization and resilience. These characters serve to highlight the societal issues the series addresses, such as gender inequality, abuse of power, and the inadequacies of legal systems. The antagonists are typically men who exploit their positions of authority, and their confrontations with Rei form the core of the series' conflict.
