During FunimationCon, Funimation announced Our Last Crusade or the Rise of a New World will be coming to their streaming service this Fall! The anime is based on a light novel series written by Kei Sazane and illustrated by Ao Nekonabe. Yen Press is currently releasing the light novels in English.
MyAnimeList.net and Funimation describe the series as follows:
A great war has raged for years between the scientifically advanced Empire and Nebulis, the realm of the witches―until the youngest knight ever to receive the title of the Empire’s strongest meets the princess of the rival nation. Though they are sworn enemies, the knight is taken by her beauty and dignity, and the princess is moved by his strength and way of life. Will the fighting between them ever be allowed to end?
Follow the cool, disgraced knight of the science kingdom who faces off against the ice princess sorceress of the rival magic kingdom. Did we mention? They’re also falling hopelessly in love with each other.
