Rei Lan began her career as a DEA agent before becoming a prizefighter. She shares a profound history with Tojo, an underworld mobster and her former lover. Their relationship is bound by the supernatural Dragon Sex Tattoo, forged during a continuous 72-hour sexual act, creating an irreversible mystical connection between them.
Four years after their initial relationship, Rei Lan encounters Tojo again as adversaries. Tojo leads the Trident Foundation, which controls global criminal operations through violence and exploitation. Rei Lan's primary drive is exacting revenge against Tojo for past transgressions. However, the supernatural bond enforced by the Dragon Sex Tattoo complicates her vengeance. This connection ignites an overwhelming sexual compulsion that challenges her resolve, creating intense internal conflict between her desire for retribution and the tattoo's influence.
Her animosity is fueled by a traumatic event where Tojo forced her partner to witness her sexual assault. Despite her determination to confront Tojo, the mystical link repeatedly undermines her efforts, resulting in a cyclical struggle between enmity and forced attraction.
