In 2003, a battle began in the center of Tokyo, between the Dragon and a being known as the Giant. After the Dragon emerged victorious, it was shot down by JSDF jets, falling into the world where magic doesn't belong. A substance that was spawned by the death of the Giant became responsible for a fatal disease known as the the White Chlorination Syndrome. Scientists took samples from the Dragon's body, which would eventually be used to create the weapons known as No. 6 and No. 7 as well as the basis for Project Gestalt.
