Set a few months after the original series, Wataru is called into action once again!

After the battle with Doakuder at Soukaizan (the "other" world where the rainbow has disappeared because of the devils), a demon world Devil came to Genseikai (human world) and stole Wataru's conscience. Because of that, Wataru's heart of justice and his memories of being Kyuuseishu (world savior) vanished. After Shibaraku and Himiko brought him back to Shinbukai (the "other" world, where Soukaizan is located), Wataru regained his memories, however his conscience was still missing. To get it back, Kyuuseishu Wataru must return to fight the devils, rescuing all of Soukaizan from catastrophe!

Mt. Soukai is in danger and Wataru is here to save it again. However, Ryujinmaru was broken into pieces during the fight with the mysterious enemy "Dobazudar"!

Wataru fell into despair, but suddenly he heard Ryujinmaru’s voice. Ryujinmaru is still alive! Then Wataru sees a vision of Mt. Sokai being upside down.

That place is called "Mt. Musokai", "the dream of the dragon". It's located somewhere unknown.

Knowing Ryujinmaru is in that world, Wataru is here again, on an adventure with Toraoh and Himiko.
