Tokyo - Akatsuki Special Zone. The country's newly established special economic zone has transferred administrative power to the large company "Sakishima Holdings". Rival companies plotted various conspiracies around tax reductions and other rights that only apply to the special zone, and finally a large-scale riot, the Akatsuki Rebellion, broke out. Domestic affairs were neglected, and Sakishima Holdings also disintegrated. Akatsuki Special Zone became an unmanaged area where national autonomy could not be achieved. A group of men guarded the city that had become a lawless zone. Humans with "sacred tattoos" that sealed the power of ferocious beasts are collectively called "SCARDs". They each have their own special abilities and defensive power that can make all attacks ineffective, such as bullets being deflected before hitting the body, and swords being shattered. "Helios" who uses the power of tattoos to protect the city, "Artemis" who protects the organization, and "public security agents" who protect order have become emerging forces and guard the Akatsuki Special Zone. Although weak, the resistance continues every day, and even so they still carry out their own "justice". They survive in such turmoil - this is a story that depicts their normal daily life.
