Let's Go! Operation Enter Darius!

시즌 1, 에피소드 4: In order to return to Darius, Daiku-Maryu must go through Death Cross Point and mend the subspace in order to prevent the enemy from going to the surface. The entry is an extremely harsh process, and Daiya, who is sitting in the Gaiking cockpit where the heat and pressure are worst, feels weak and nauseous. As they travel through the subspace, they run into a Demon Beast sent there by Saspazi, one of the four generals of the Darius Army. Since Daiku-Maryu is emitting energy to mend the subspace, it is not strong enough to counterattack the Demon Beast. Only Gaiking is capable of withstanding the heat, and despite the great danger of fighting in the subspace, Daiya takes Gaiking outside and manages to kill the enemy.
