EPISODIUM
Natsume is fatally injured by a random soldier after his fight with Kuse, but asks that his death be concealed from Yukina for the time being. Natsume's death causes Kazura to realize that he has been living in the past instead of looking forward to the future and he rejoins his former allies. When the Sakurai Kikan confront Isao, he explains that humanity must experience tragedy firsthand to avoid war again, but is refuted by Shizune, who suggests that Isao's actions were actually for the sake of his late fiancée. When Sakurai appears and shoots at Yukina, Isao takes the shot and dies. Having infiltrated Isao's group to eliminate him, Sakurai reveals his own interests in the nuclear arms to change fate, but his assistant Ichishi erases his memories. Shizune requests that Ichishi erase her memories so that no one will experience the same fate as her. Meanwhile, Aoi and Kazura combine their efforts to hijack the plane containing the atomic bomb and drop the weapon in the ocean. However, only Kazura is seen escaping the crashing plane, while Aoi's fate is left unspecified. Two years later, Yukina visits Feng Lan at her restaurant, where the latter shows her the group photo they took back in Hokuryou with Kazura added in it. Yukina hears a violin being played badly, reminiscent of Aoi. However, she sees that the Japanese Army is marching on the streets which indicates that the war is coming soon.
