Maō Lucifer Koran (The Descent of the Great King). It seemed that the large-scale battle that occurred in the fortress city of Granden would be stopped by Theodore and others. However, the eerie monsters and huge cocoons that emerged from the dimensional cracks in the sky near the west side of the fortress city create further confusion. The small soldiers led by Clarice who rushed to the scene quickly and the dragon riders who sensed the unusual situation and invaded from Ryuo Province temporarily fight together against the monsters, but suddenly they fall from the sky and the huge cocoons change the situation. When General Durus, the great hero who finished the battle in the fortress city, rushed to Clarice and his horse to Clarice and others, a terrible scene spread in front of them. On the other hand, Theodore, who was doing the post-treatment in the city, was also appalled by the presence that appeared from the dimensional cracks. It belonged to Satan who suddenly disappeared from before them long ago. Theodore, who ignored everything and rushed to his former sworn allies, finally reveals the true figure in front of General Durus in order to calm the raging sworn allies.
