Written five years after "Akuma-kun Sennen Oukoku", this one-shot tells the story of how the now deceased Akuma-kun has managed to take command of all the beasts residing in Hell.

With the minions of Hell on his side, Akuma-kun attempts to take over the human world and unite both dimensions as one. Naturally, the human world is not too keen on this idea and before long, Kitaro, with the help of all of Japan's Yokai, set about to stop Akuma-kun once and for all in an almighty battle!
