...After humanity had gone through the Second World War, people with supernatural abilities or grotesque features began to be discovered. Soon, these abilities or characteristics became known as "Special Powers", and those who possessed them as "Special Holders". Humanity sympathized with the early "Special Holders", but as their numbers expanded, their abilities started to be feared and avoided, and attempts to expel them from society arose. "Special Holders" also began to use their abilities against humanity. Some to defend themselves, while others to show off their abilities. Uprisings, crimes, and other similar events were commonplace as a result of this vicious cycle, and the battle between the two sides was escalating all over the world.

Likewise, Japan too was not an exception, as there was an outbreak of conflicts between humen and "Special Holders". During that period of unrest, all the time there were grievous events like the government being temporarily suspended to fulfill some of its functions or a failed coup d'état attempt in a Japanese Self-Defense Forces academy. Japanese government took steps to address the country's unstable situation. It has formed a Special Riot Police force that includes both humans and "Special Holders". The chief of its second division, Kashiwabi Ayato, and his subordinates worked hard to maintain a public security. A few years after the establishment of the Special Riot Police, crime rates fell and public order was restored as a result of its members' efforts. Every day, Special Riot Police officers in Japan, which had briefly returned to calm, fought hard to keep Special Powers crimes under control.

Following a certain case, the number of organized crimes perpetrated by Special Holders began to climb. Public unrest, government critics, and similar issues were rapidly spreading in proportion. All members of the Special Riot Police were called to investigate the case, each with their own set of suspicions. Before long, they were swallowed into a great conspiracy encompassing the whole country. The Army, which is taking actions to suppress the newly erupted conflict between humans and Special Holders with military power, and the protagonist with Special Riot Police, which is making efforts to settle the disturbance. What will you see in this critical situation, where all of these powers are mingled, after all rights and pains come together?..
