Makai Kingdom takes place in the netherworld, which is ruled by an arrogant ruler, Lord Zetta. After the oracle, Pram, tells him that his rule is about to come to an end, Lord Zetta sets out to find a sacred tome that contains a record of all events past, present and future. Zetta?s fears are confirmed through the tome, and in his rage he destroys it. In a twist of fate, the book?s destruction begins the destruction of Zetta?s kingdom.
In a last attempt to save his kingdom, Zetta merges with the tome. His actions save the world, but leave it as an empty void. Pram and the rest of Zetta?s demon generals set out to find the newly changed lord. Meanwhile, Zetta sets into motion a plot to raise an army and recreate the world in his own image.
