Eine mysteriöse Gruppe von ehemaligen Bewohnern aus dem Kaiserreich Gazu stoppt Chaika und ihre Gefolgschaft und fordert ein Wegegeld.
The head of the Kleeman Agency, Konrad Steinmeitz, ask Alberic to take a break on searching Chaika Trabant. While he does some research on Emperor Arthur, he reveals to Vivi and Zuita Brusasco that he could not find information about the man before the war, which raises his doubts. Elsewhere, Toru and his companions encounter a group who calls themselves the "Neo Gaz Empire', who aims to bring back the Gaz Empire under a blonde haired girl who calls herself "Princess Chaika". While Chaika befriends the princess, Toru, Akari and Fredrika have suspicions about the group. Their suspicions are confirmed after defeating the Neo Gaz's men, the group admits they are actually former Gaz Empire citizens who turn to thievery after being abandoned by the Six Nations. While Toru wants to leave, Chaika begs him to save the fake Princess Chaika, whose real name is Julia, after learning she got captured in a failed breaking and entering. Toru and comrades rescues Julia, which she and her friends thanked them but not before Toru learns, even during his rule, many of his citizens don't know much about Emperor Arthur. Meanwhile, the Council of Six Nations deals with a rebellion by Duke Gillard Gavarni who controls a floating fortress.
Suite à un détour pour éviter la ville, le groupe est arrêté par des gens se réclamant partisans de l'empereur Gaze. Ceux-ci, après avoir exigé un droit de passage, expliquent qu'ils souhaitent former un nouvel empire, avec une nouvelle princesse Chaika à leur tête. Cette princesse et ce groupe semblent cacher bien des choses...
