Agate

Season 1

The Valley of Hell has somehow been filled with water, and the overpressure of the water has squeezed through the rock formations, taking a heavy toll on the demonic clans that live in the underworld. Prince Alois dives to the bottom of the Hell Lake to investigate and discovers that the source of the disaster comes from the tears of half a witch's head. In order to bring the witch who threw the head to justice, Alois set off to the surface.
