A year has passed since the battle between Gamera and the Gyaos, and Japan has struggled to rebuild its cities in the meantime. The military has kept a cautious vigil on the nation's coast, but so far Gamera has yet to return. Suddenly, a series of bizarre incidents reveal a new threat to the land of the rising sun. On a moonlit stroll, science instructor Midori Honami watches as a huge meteor plunges into the mountain snow. The next night, two security guards are horrified as they see large insect-like creatures stealing glass bottles from a nearby warehouse. Soon after, the entire city of Sapporo is covered with strange plants and the link between these events soon becomes clear. |
