The Awakening of Calamity

Summary
Louise and Saito are dancing in the grand ballroom, with Louise lost in the thought of Saito's life-risking Lífþrasir power. The next day, Siesta walks into Louise and Saito's room to see Louise sitting on the edge of the bed. Agnès arrives and inform Louise that she, Saito, and Tiffania are called on by Henrietta. The Queen tells them that His Eminence has requested their urgent help, and calls upon Sylphid to escort them there. Upon reaching Romalia they see Aquileia being engulfed in flames and are attacked by a swarm of dragons. Julio rescues them from a fire blast launched by an enormous dragon and escorts them to Romalia. The Pope requests the trio's help to stop the legendary "Ancient Dragon" and asks Saito to use his new-found abilities, to which Louise objects. When they arrive at the location where they will confront the dragon, Louise informs Saito the consequences of using Lífþrasir's power, but he agrees to use them to protect Romalia and Louise. The accompanying army trapped the Ancient dragon in a valley, and Vittorio uses his Void magic on the dragon; it usually functions as a Recovery spell, but has a damaging effect against entities of evil. Tiffania uses her Memory spell to cease the dragon's army. Saito use his powers to strengthen Vittorio, but the Ancient dragon possesses Julio's dragon, causing it to move towards the dragon's mouth as it begins blasting them with fire. Derflinger demands Saito, draws him to absorb the attack, but the Ancient dragon's power proves too much and Derflinger shatters, propelling Saito off the back of the possessed dragon only to be caught by Louise and Tiffania. Knowing he can no longer fend off the dragon with his magic, Vittorio shoves Julio off the back of his dragon, rescuing him at the cost of being eaten by the Ancient Dragon.
