While Sakurai is displeased with Aoi's actions regarding the prophetess, he allows Aoi to remain in the group. Yukina hesitantly shares the vision Isao presented to her with the others, describing the vision as "hell". During the group's next mission to find evidence that the Chinese are smuggling in weapons from Germany at the Dalian port, Kazura is ambushed by a group of Westerners. When Isao comes to his aid, he reveals to Kazura a secret base run by Ichinose, where nuclear weapons are being developed and shares with him his ideals, inspired by the events of the First World War that concluded with the signing of the Treaty of Versailles on June 1919. Upon returning to the port, Aoi and Natsume set a trap for Isao. A conflicted Kazura, recalling the speech that Kanji Ishiwara gave when he was in military school, chooses to save Isao and teleports away, leaving Aoi, Yukina, and Natsume shocked by his actions.
