The Gosei Angels finish preparing for Nozomu's birthday party when Datas stops them by revealing that the Erurei Box is on the Tokyo Metropolitan Government Building. With Nozomu understanding, the Gosei Angels head to the building where Kinggon is waiting for them. By then, it is revealed out that the Yuumajuu's previous plan was actually a lure for Makuin to absorb their Super Gosei Power, regenerating himself within the Erurei Box in order to create the Yuuma Hole to destroy the entire planet. With Gosei Knight holding Kinggon off, the Gosei Angels enter the Yuuma Hole as they tell Nozomu that they must risk not coming back if it means saving the boy and everyone on Earth. Fighting through the Bibi Soldiers, the Goseigers assume their Super Forms to fight illusions of Makuin within the Yuuma Hole. They eventually find the real Makuin and destroy him with their Miracle Gosei Dynamic. However, the Goseigers are trapped inside the Yuuma Hole as it closes around them. Outside, after being defeated by Gosei Knight, Kinggon uses the Bibi Bugs to enlarge and overpowers Gosei Ground to avenge Makuin. However, after being contacted by Datas, the Master Head sends the Goseigers to the core of the new Heaven's Tower. Their Miracle Gosei Headders attach to the core to create Gosei Ultimate. Using Gosei Ultimate to return to their dimension, the Super Goseigers convert it into its robot mode to battle Kinggon before destroying him. Soon after, the Gosei Angels learn from Datas that the Master Head is gone and the new Heaven's Tower cannot be built, stranding them on Earth and on their own. But, as they decide to celebrate Nozomu's birthday regardless, the discarded Bibi Bugs' hive sinks into the water.
