High Priest Geo is desperate to help save the kingdom and its people. He unleashes the mighty wizard Dark Schneider, a man who used to be an ally of the villains. Unfortunately, Dark Schneider has his own plans in mind. Will he stop the Four Lords of Havoc or join them in their conquest of the world? [Written by MAL Rewrite]
