The Holy Kingdom of Roble, ruled by King Calca (Saori Hayami), once lived in peace. However, when it is suddenly invaded by the Demon King Jaldabaoth (Masayuki Kato), the Holy Kingdom is devastated. Holy Knight Commander Remedios Custodio (Hitomi Nabatame), her follower Neia Baraja (Yoshino Aoyama), and their entire army then seek help from the Sorcerer Kingdom of Ains Ooal Gown to take revenge. Sorcerer King Ains (Satoshi Hino) agrees to help Remedios on the condition that, if they are victorious, he will receive Jaldabaoth’s demon servant.
