In the year 2041, World War III has killed out two-thirds of the human population, and belief in any deity or beyond-human entity is deemed a ridiculous thought in the newer organization. To protect civilians from having potentially damning ideas, the government has formed a Special Weapon Enforcement section to apprehend and rehabilitate such believers. The Kirihara brothers, Naoya and Naoto, who had been kept hidden from society for years by their captors to conceal their psychic skills, were promised freedom once the world was ready to accept their presence. The brothers are now on the run from the Enforcement's loyal agents, Yuuya and Takuya Kuroki, as they wander in the horrible new societal atmosphere where psychics are not tolerated.
