The following year, the government dismantled public institutions including police forces
in each country.
At the same time, a surveillance system with AI drones and AI surveillance cameras was
set up.
Prohibition of owning property, prohibition of armament, and protecting yourself by fighting.
These 3K law was enacted, and countries were plunged into chaos.
　
People relied on people with power, and a Gang Leader System was born at the school.
And it was the same with Mob All Megane Academy, at Riverside City where all MOBs
wear glasses.
The gang leader demanded a huge payment.
Students led by Aira, a black gal with a strong fighting spirit, formed the Black Gal Group.
The students of MOB joined to either the Gang Leader or the Black Gal group, and a war
broke out.
　
However, the Black Gal group was outnumbered by the Gang Leader group, whose strength
was overwhelming.
Aira was captured. The story begins with the remaining four members of the Black Gal group
They begin to carry out a rescue mission for Aira!
