Hailey Copter, also known as Heli Copter, operates in the futuristic city of 2XXX Budapest within the United Republic of Hungary. She belongs to a team of futanari goddesses called "Drivers" or "Jewels". This group battles General Rhino's gang, which terrorizes the city to steal life-sustaining energy crystals from innocent women; theft leaves victims as lifeless husks. Hailey and her team wield specialized biological weapons in combat: retractable penises that flood enemies with intense pleasure, their primary and most effective tactic for incapacitation. Their mission focuses on halting General Rhino's operations and restoring stolen energy crystals to their rightful owners.
