The Great Battle II: Last Fighter Twin

Half a century after SD characters moved to the colony, SD Nation had been developing peacefully and gently. However, suddenly the colony's environmental management system began a runaway of unknown cause, the evil monsters began to rampage on their own, and the peaceful SD Nation turned into a lawless zone. In order to restore SD Nation, Gundam F91 , Ultraman Great , Rider RX , Fighter Lore , stood up to find four gachapon capsules scattered around the world that all collected things will fulfill any wish, anxiety and hope I decided to leave on my chest. Can we regain the peace of SD Nation?

At that time, however, the four had no idea that Dark Brain, the terror and killing king of Colony Side 3, the furthest from Earth, was also aiming for the capsule.
