Never Give Up, Goseigers! (ネバーギブアップ！ゴセイジャー Nebā Gibu Appu! Goseijā) is the thirty-first episode of Tensou Sentai Goseiger. It is the first half of the two-part final battle with the Yuumajuu.
Makuin merges his power with the Erurei Box, creating an indestructible platoon that can only be defeated if the Goseiger can stop him!
After succeeding in their research on the Erurei Box, Makuin and Kinggon prepare for their master plan. At the Amachi Astronomical Institute, the Gosei Angels wonder when the new Heaven's Tower will be finished as Nozomu arrives and reveals that his birthday is tomorrow. The five then respond to the Yumajuu's attack as Makuin finished spreading his mold across the city via Nekin Mail. The Goseigers battle the leading Yuumajuu, managing to overwhelm the two before using the Gosei Buster on them. However, the Yuumajuu turned out to have been faking their defeat as Makuin reveals his plan to use fear to further his Erurei Box-empowered mold. By then, Gosei Knight reveals he already dealt with all traces of the mold as the leading Yuumajuu weaken him with their Yuuma Buster attack before leaving. Before limping off, Gosei Knight reveals he only halted the mold spreading by freezing it. While the Gosei Angels learning the mold could be destroyed when Makuin is defeated, the mold thaws as it makes people sick. Arriving to find the leading Yuumajuu after refreezing the mold themselves, the Goseigers assume their super forms to battle them. After the Landick siblings destroy Makuin's staff to disable the Yuuma Buster, the Goseigers use Miracle Gosei Dynamic to finish the fight. However, the two Yuumajuu endured as Makuin enlarges with Gosei Great formed to battle him. However, none of Gosei Great's equip forms have any effect as it is overpowered. Though Makuin messes with their heads by telling them of the horrors of humanity, Nozomu reminds the Goseigers not all humans are bad as Gosei Knight arrives and tells them to summon the Mystic Brothers. Forming Mystic Gosei Great, they manage to weaken Makuin before Ground Gosei Great freezes the Yuumajuu and uses Ground Great Strike to finish him off. With Makuin dead, his mold fades as the Goseigers thank Gosei Knight, who reminds them that Kinggon is still on the loose before taking his leave. Later, as the Gosei Angels go to prepare for Nozomu's birthday, Kinggon finishes his own plans for tomorrow by implanting the enlarged Erurei Box onto the Tokyo Metropolitan Government Building to continue what he and Makuin started.
