Fan Casting Bastard!!

Four centuries ago, Earth suffered a cataclysm caused by the demon Anthrasax before she was slain by the Dragon Knight, plunging the world into a new dark age. In the present, the Kingdom of Metallicana is attacked by the Dark Rebel Army who seek to resurrect Anthrasax. This prompts the high priest to ask his daughter to awaken Dark Schneider, a dark wizard and founding leader of the Dark Rebel Army who reincarnated himself within the body of 14-year-old Luche Renren. In time, Dark’s allies learn of his true nature and ties to the calamity that befell the Old World.
