At an unspecified time in the future, Earth’s resources are exhausted and habitats are no longer stable. Humans have been transferred to a new solar system, IOTA Synthetica. In this new solar system, everyone will have a stable life to develop and live. However, things began to change when a mysterious radiation source appeared. It has moved through the new solar system and brought about inanimate objects to attack mankind. From this uprising, the Galactic League has summoned the Gunnac command and demanded they protect humanity once more.
