On February 29, 2000, a group of Möbius meteorites fell to Earth. These meteorites brought with them a new material called Möbius dust, which dissolves in air and can work miracles. The day of the Möbius meteorites' fall was nicknamed 2.29, and from that moment on, economic inequality in Japan increased dramatically. A group of people, exasperated by the disparity in wealth, responded with acts of terrorism. The police created a special unit to combat terrorists and a school to train their members.
