-White Out- "Near this sea, there is fog." After leaving the ancient city of Garm, Menou and her companions arrive at the port town of Libelle. The fog of Libelle is said to be such that once you enter, no one has ever returned. It is the infamous disaster known as the "Fog Demon Palace," which once devoured the Southern Islands Alliance. In search of a way to finally kill Akari, who can resurrect even after death, Menou comes up with the idea of using that cursed fog to fulfill her duty as an executioner. Amidst this, the daughter of the Duke of Libelle, Manon, approaches Menou and her friends. Her actions, which were supposed to be "nonexistent," begin to twist the fate of Menou and even Akari in an unintended direction――. A story of her killing herself, the sudden turn of events in Volume 2!
