While the lake was dried up, many Debo Monsters were brought back due to Great Land Devil Gadoma opening a portal to Deboth Hell, ingesting items to regain their physical forms before the lake was restored after the destruction of Mad Torin. The Kyoryugers later wiped out the last of the revived Debo Monsters. Shortly after the Kyoryugers faced the revived Ferocious Knight D, who had escaped from Deboth Hell as well, the ten Kyoryugers soon foiled his plan to conquer the world and destroyed him as well.
The absence of Resentful Knight Endolf, who was claimed by Raging Knight Dogold to have been killed by the Kyoryugers when in actuality he had become Dogold's host after being enveloped by the armour, in the Darkness of the Land revealed to Hundred-Faced High Priest Chaos that Dogold had lied to him, forseeing his treachery before Endolf eventually broke free.
When Deboth began his final attack, with the Darkness Clock starting its countdown, numerous portals to Deboss Hell opened up in anticipation of Earth's destruction. Anticipating this, Dantetsu Kiryu and Wise God Torin, mentor to the Kyoryugers who defected from the Deboth Army 100 million years ago, arranged for the former to kill the latter as a member of the Deboth Army so he would go to Deboth Hell. While the Kyoryugers saw Dantetsu seemingly join the Deboth Army and condemn Torin to eternal damnation, as Daigo discovered when he heard the Earth's melody, Torin was infact sent to Deboth Hell by Dantetsu with his righteous heart still intact to defeat all the Debo Monsters laying in wait there. Thus, the Debo Monsters that were summoned back up to the surface would shortly after be destroyed again, as Chaos discovered when Mad Torin returned and died almost immediately.
Revealing the truth to the Kyoryugers, the Spirit Rangers Ramirez and Tessai, having passed their Kyoryuger mantles to living successors, joined Torin in the Darkness of the Land in order to destroy Deboth Hell itself to prevent Deboth from reviving, thus finally defeating the Deboth Army for good. Torin and the Spirit Rangers made their way to a pillar that served as the core of Deboss Hell to destroy it. Realising this, Deboth had Chaos allow himself to be killed by Dantetsu as Kyoryu Silver, who only realised afterward, so he could go to the Darkness of the Land to stop them. However, he was stopped by the Earth's melody and the arrival of Candelilla and Luckyuro who were able to be there due to Luckyuro's Rattatta Lantern which allowed the living to enter. Torin, Candelilla and the Spirit Rangers combined their power into an attack which forced Chaos into the pillar, destroying them both and finally vanquishing Deboth Hell. Deboth himself would soon after be destroyed by Kyoryu Red Carnival powered by the Earth's melody.
