Deboth Hell

Deboss Hell (デーボスヘル), also commonly known as the Darkness of the Land (大地の闇) located under Lake Madō, is where the souls of Debo Monsters end up after being destroyed.

While the lake was dried up, many Debo Monsters were brought back due to Great Land Devil Gadoma opening a portal to Deboss Hell, ingesting items to regain their physical forms before the lake was restored. 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 Deboss 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 Deboss 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 Deboss Army 100 million years ago, arranged for the former to kill the latter as a member of the Deboss Army so he would go to Deboss Hell. While the Kyoryugers saw Dantetsu seemingly join the Deboss Army and condemn Torin to eternal damnation, as Daigo discovered when he heard the Earth's melody, Torin was infact sent to Deboss Hell by Dantetsu 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.
