The six heroes are about to lead their most perilous battle! Objective: to prevent their leader Meliodas from becoming the king of demons and to free Princess Elizabeth from the curse that condemns her to a certain death. To make possible the impossible, the brave ones burst directly into the enemy territory: Ludeciel the lightning, leader of the four archangels; the unrivalled Escanor, Lion of the Orgueil; and Merlin, the greatest magician in the world. Will they be able to settle their account to the two royal instructors, Chandler the nippler and Cusack the drowsy? The Battle of Camelot promises to be decisive.
