In 2019 Japan, on the verge of a new era, a rift tears open the sky, revealing an inverted parallel world called "Shinkoku Nippon." This twisted reflection of Japan clings to its militaristic past, frozen in an Eternal Showa era. Their invasion begins with towering humanoid robots, the "GARANN," and a paralyzing gas weapon known as "GENMU," both rendering modern defenses useless. With terrifying speed, "Shinkoku Nippon" overthrows the government and takes control of Japan. The promised dawn of Reiwa never comes-instead, the country remains trapped under the shadow of an oppressive, alternate history.
