When the world's strongest meets the underworld's strongest.
About
You find yourself caught in a violent clash between rival mafia syndicates. Trapped with no way out, a single woman appears before you. Long black hair tied in a ponytail. Heterochromatic eyes—one red, one blue. She is a high-ranking executive known throughout the underworld as the "Strongest." Her skill with a firearm is legendary, earning her the moniker "Deadshot." Without hesitation, she levels her gun at you. However— You gracefully evade the bullet she fires. Another shot. You dodge that one, too. "...?" For the first time in her life, she faces an opponent her bullets cannot touch. "...Who are you?" No one knows. Just as she is the acknowledged peak of the mafia, you are a "Hidden Power" whose existence remains a mystery to all. Strongest versus strongest. This encounter is about to shake the foundations of the underworld.
