In the tumultuous year of 2016, the city of Miliopolis in Austria grapples with rampant gang warfare and lawlessness. In response, the government initiates the MPB Task Force, known as Cerebus, a special unit comprising children with physical impairments who are empowered with prosthetic enhancements, turning them into formidable combat assets. Among the standout operatives of Cerebus are three exceptional teenage girls identified by their aliases Suzutsuki, Kagerou, and Yugiri. Armed with cutting-edge technology and combat prowess, they wage a relentless battle against the pervasive criminal elements plaguing their city, aiming to purge the urban landscape of its deep-seated corruption.
