Synopsis
Both the Photon Power Laboratory and Hell Island have suffered heavy damage in the fighting. As both sides rush to repair, Grand Duke Gorgon launches another attack on the lab, leading the demonic Mechanical Beast Girania β5 and the Iron Cross Corps. Girania β5 takes down Diana A and Boss Borot, then starts burrowing deep beneath the lab. The plan is to detonate a cobalt bomb hidden in its body at a depth no attack can reach. To stop the disaster, Professor Yumi puts the lab's full technology to work in a desperate search for an answer.
