Story

In the 91st century, mankind built space colonies and moved their residence into space. But the environmental control system of the colony group "Little Japan", which was located on the other side of the moon LaGrange 2, suddenly shut down, and its core "Dire 51" began to attack humanity. Dire 51 violently attacked other colony groups, collected materials and debris, and reinforced and expanded its own colonies. The huge and strange appearance of the enemy's eyes became a sign of hatred and fear among humans. Although the cause of Dire 51's malfunction was hastily investigated by many research teams, no conclusion about the cause could be found. In the meantime, Dire 51 develops a powerful armor and begins its attack on Earth. The battle on Earth intensifies and the situation goes into a tailspin. To defeat the attacking forces, Earth finally relies on the MUSHA unit.
