Hibiki is put into intensive care at the JP's' Tokyo Branch. As the demon summoners look on, Io can't help but feel responsible for his current condition, although she is comforted by Jungo and Airi. Meanwhile, Alcor is visited by Botis and Bilfrons, the former of whom tries to attack him because of his supportive stance on the humans. Fumi updates the JP's phones with software capable of summoning stronger demons. The next day, Io, Daichi, Airi, Jungo and Hinako have breakfast together in a single moment of peace and officially introduce themselves to each other. As they go to exchange emails, they all simultaneously receive each other's death clips. Suddenly the last Septentrione: Benetnasch appears and destroys the Sapporo barrier with a single attack allowing the Void to consume the region. As Fumi outlines that it possesses the abilities of its predecessors, the Osaka and Nagoya regions are wiped out each with a single blast. Yamato then orders everyone to begin the operation.

With the Trials of Polaris behind them, Alcor appears before Hibiki and co. and states that he intends on killing Yamato of his own free will and in doing so, entrusting the fate of the world to Hibiki, a battle which Yamato accepts. As their battle begins, Hibiki explains to Daichi and Io what would happen to the world if Yamato has his way after meeting with Polaris. While attacking Yamato with tentacles, Alcor realizes that Yamato had been steadily drawing him closer to the Tokyo Tower to enhance his use of the Ryumyaku. Afterwards, they take a short pause and exchange threats. Alcor expresses his support of Hibiki's future since he was treated as an actual person when with him, although Yamato retorts that Alcor should revert to being a mindless tool, and if so, he would be allowed to see his vision of the future. Just then, they both receive each other's death clips. Hibiki also receives their death clips and decides to keep his promise to Yamato by stopping him.
