How do you resolve a conflict between powerful spirits of famous heroes competing for a prize capable of granting any wish? Fight a war that will cost blood, sweat and tears? Lots of work, how about a game show competition?
Carnivel Phantasm takes several characters from Type-Moon's original works and places them in a variety of light-hearted settings that parody their respective series. Watch as Lancer suffers due to his terrible “Luck” stat, or watch the selfish King of Heroes gleefully kneel before a King of Knights dominatrix. Just remember to leave your sanity before entering.
The Season 1 Blu-ray and DVD discs went on sale on June 2, while the Season 2 Blu-ray and DVD were originally scheduled to be released on August 25, but the release was delayed twice due to production issues, and will now be released on October 13th.
