In the aftermath of the battle, the sky is now in plain view, prompting Simon and Kamina to set off on a journey alongside Yoko to explore the wastelands of the surface. Soon, they join the fight against the "Beastmen," humanoid creatures that terrorize the remnants of humanity in powerful robots called "Gunmen." Although they face some challenges and setbacks, the trio bravely fights these new enemies alongside other survivors to reclaim the surface, while slowly unraveling a galaxy-sized mystery.
