[Machine Translation] Princess La Follia invites Kojo and Yukina to visit the Kingdom of Ardigia. Kojo was not too keen on the trip, but when he is told that Natsune Kanase will accompany him, he reluctantly decides to accept the invitation. There are forces within the court that do not like Natsune's presence, and La Follia's true request was to protect Natsune from them. At the same time, a ceremony was scheduled to be held in Ardigia to commemorate the signing of a peace treaty with the realm of the War King, and there were concerns of terrorism by forces opposed to the treaty. Then, a mysterious monster attacked the royal palace in Ardigia, setting in motion a large-scale terrorist plot involving the Warrior Realm. The Koshiro and the others are caught up in the middle of it all.
