The Lione Empire and the Heavenrose Kingdom are on the brink of war, and there's only one way to stop it: recapturing the sower of discord, Saint Debonaire! This mission brings Alphina to the capital of Heavenrose, where the Saint has taken refuge. There, she makes contact with an underground insurgent organization called Mordeus Scythe-and it turns out their leader is her former fiancé's right-hand man and the empire's most brilliant mind, Kithling! Having secured a face-to-face meeting with the Saint, Alphina recruits Kithling and her beloved little brother, Carl, for the final showdown!
