History

Backstory
Ten years ago, during the Mars manned exploration project 'Project Sky,' astronaut Soichi Isurugi discovered the Pandora Box, whose light caused the Skywall Tragedy, dividing Japan into three nations: Touto, Hokuto, and Seito. He himself became a subject of human experimentation and lost his memories, but under Soichi's protection, worked as a researcher at the Touto Institute of Advanced Matter Physics, analyzing the Pandora Box. He regains his past and fights Evolto to create a new world, staking the fate of the world.
