There are only five hours left to save the world. Torin does his best to defeat Debo Monsters in the Land of Darkness, but Zorima begin to escape and infest the Earth. Ramirez and Tessai decide to join him, as they have decided on two people to pass on their powers to, but who are they? And Utsusemimaru goes into battle one last time against Endolf and Dogold.
With only five hours left until the end of the world, the Kyoryugers transform as Endolf summons a horde of Zorima. Chaos and Endolf are about wipe out the Kyoryugers along with Dogold and Killborero when Tessai and Ramirez arrive and use a barrier to block. The two reveal that Torin is going to destroy the core of Deboth Hell and that they are going to help him. As Killborero enlarges to disrupt the barrier, the Spirit Rangers reveal their replacements who will carry their mantles in their stead: Yuko and Shinya with the former revealing to Nobuharu that she knew of her brother's actions as a Kyoryuger. With Doctor Ulshade leading the Zyudenryu to hold off Killborero, Yayoi arrives to upgrade the Victory and Maximum Zyudenchi with the Earth's Melody. Yuko, Shinya, Yoyoi, and Dantetsu assume their Kyoryuger forms to hold Chaos and the Zorima at bay while the main Kyoryugers and Minityra make their way to the Frozen Castle. As Ramirez and Tessai meet up with Torin in Deboth Hell, the main Kyoryugers find their transformation canceled by Deboth as Endolf and Dogold. Telling the others to leave, Utsusemimaru holds off the two Deboth Knights. But during the fight, tricking Endolf into letting his guard down, Dogold suddenly attacks to break the Resentful Knight's hold on him. Telling Utsusemimaru to help him, Dogold forms himself over the samurai to combine their Lightning Afterglow attacks to destroy Endolf. Once back to possessing his Cambrima, his armor heavily damaged, the dying Dogold tells Utsusemimaru to fight him so they can settle things here and now. Accepting his request, Utsusemimaru defeats Dogold but is mortally wounded in the process as he collapses. With Nobuharu holding off a horde of Zorima, and then Ian and Souji dealing with the fortress's last line of defense, Daigo and Amy use the Deinochasers to enter the Frozen Castle where another legion of Zorima waiting for them.
