Homeron informs Shu and Co. about Delphinium who is a Secret Intelligence Agent from Gran Kingdom responsible for the theft of the Extra 7. The group then sees the warships of Sabalu Country (which used to be part of Gran Kingdom) passing. Zola concludes that they give the Sabalu Country airships a warm welcome when the Warship Norg is amongst the Gran Kingdom ships. They managed to obtain one of its Mechats for that action. As the battle starts, they find the Norg and Shu uses Blue Dragon to get Homeron on board. When Kluke lands the ship on the Norg, a fight between the robotic soldiers ensues. Homeron manages to gain some information and prevent the Norg from crashing. He then tries to get info from the ship's captain on where it took Delphinium. When he does squeal that General Logi has the Extra 7, the Norg starts to descend to the ground.

The battle against Logi's Independent Flying Squadron rages on as Shu, Kluke, Jiro, and Bouquet struggle to take down Cynthia while Zola and Marumaro do the same for Gilliam and his minions. When Marumaro takes down Bishop, he and Zola focus on the remaining two when Gilliam and Todd's Power Boosters overload. When this is discovered, General Logi orders Cynthia, Gilliam, and Todd to retreat, but Gilliam and Todd are shot down by Zola after Marumaro decoyed them. Despite Cynthia going into overdrive, she is defeated by Jiro anyway.

Conrad and a Knight Master named Griz join up with resistance headed up by Legolas and Daner in a nearby city and joins him in exploring the ruins of the Investiture Beings there. Shu, Bouquet, Marumaro, and Noi arrive at the city as Lotarus is encountered by Delphinium and Deathroy. Deathroy unleashes Chimera as White Brigade's weapons fire at Lotarus. She manages to evade the weapons and Delphinium's shadow before turning into her dragon form. While Lota deals with Delphinium and Deathroy, she also unleashes winged creatures that attacks the White Guardians. Lota takes the opportunity to escape while Delphinium and the White Guardians are occupied. Shu meets up with Legolas and Conrad and they descend into the underground caverns that are underneath the city. Noi then reads the messages found on the floors of the cavern. When Shu has Blue Dragon punch the artifact on the wall, he is sucked in.
