In 2041, a devastating World War III had decimated two-thirds of the global population, ushering in a new social order that denounced the notion of higher powers. In an effort to enforce conformity, the government established the Special Weapon Enforcement unit to capture and reform individuals who held subversive beliefs. Citizens were subjected to constant monitoring to ensure compliance. Brothers Naoya and Naoto Kirihara possessed psychic abilities and were forced into hiding by their captors. They were promised freedom once society was accepting of their talents, but psychics were now viewed with suspicion. Fleeing from the relentless pursuit of zealous Enforcement agents Yuuya and Takuya Kuroki, the Kirihara brothers struggled to evade capture.
