Year 202X. A unified world government established through simultaneous global default dismantled public institutions — including the police — replacing them with AI drone surveillance and an aggressive three-statute law that criminalized property ownership, armament, and self-defense. Countries collapsed into chaos. People organized around those with power, and at Mob All Megane Academy in Riverside City — where every student is a MOB and every MOB wears glasses — a Gang Leader emerged and demanded protection payments. A group of students led by Aira, a determined fighter with a strong will, formed the Black Gal Group in response. War broke out. When the Black Gal Group was overwhelmed and Aira was captured, four of her remaining members refused to let it end there. Their rescue mission begins now.
