With the subjugation of the Principality of Amidonia accomplished, Souma, the provisional king, begins the post-war cleanup process with his next move, Project Lorelei. It is an entertainment program that uses the Jewel Voice Broadcast. It was originally only thought that this program would amuse the people of the Kingdom, but it is being broadcast in occupied Van, too. What does Souma hope to accomplish with that...?! Then, when Souma takes some time off to rest in the capital of Amidonia, Van, with Juna and Tomoe, he encounters Jeanne Euphoria, the younger sister of the Empress of the Gran Chaos Empire. What sort of "negotiation" does the "realistic" Jeanne, who supports her idealistic sister, have in store for Souma...?!
