De Carne and Arthur have been chosen by the legendary sword, excalibur, to fight on their own against Meliodas, his friends, and the other demons. The demon lord , however, is not so sure. He says that the holy sword will not be enough for Arthur to defeat them on his own. He tells Arthur that he has made two mistakes: first, he did not have the strength to fight, and second, he allowed his lover, Desdemona, to run away with her lover. He promises to take Desdemonas home before he kills him.
