Much of the students make preparations for a party by Tori's request. Masazumi is assigned to room with Miriam Poqou, a disabled academy student. Kimi Aoi watches over her brother Tori, who seems to be frightened by Horizon's place of death. Margot Naito, who is talking with Malga Naruze, gives Masazumi a packaged video game to deliver it to Tori. In the woods, Masazumi hears from her father about the tragedy that befell Horizon and the remorse that impacted Tori ten years past. Meanwhile, the Musashi is approached by ships from K.P.A. Italia and Trés España, two of the Harmonic Divine States with unknown intentions. The students stay at the academy overnight to exorcise any spirits within the area.
