[Enkai-Underworld]
Compared to the cities on the surface, there's a much larger space down here, and there's also a greater number of demons residing within.
Moreover, aside from the direct lineage of demons with Toad Ancestor blood running through their veins, the Underworld is also home to numerous 'Dependents'.
For example, the 'Womi Giants,' who resemble primitive wild men with huge builds, live within massive caves they excavated themselves, and they generally handle the excavation of the Underworld caves and the moving of giant boulders.
Or the 'Invisible Children' who wander through corridors, cling to murals, or hide within pools of water.
They come in diverse forms, constantly changing, serving both as the Underworld's covert guardians and lethal traps lurking in each area.
Besides, the number of different types of external demons reliant on Enkai is at least in the double digits.
