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.

Not having anymore hesitation to fight, Hibiki reminds Yamato of their promise of defeating him and having an audience with Polaris. As their battle begins, Yamato notes that Hibiki is driven by his anger towards him and his warped reasoning behind sacrificing the lives of everyone. Although, Hibiki defends by stating that as a human, he cannot allow such injustice to prevail, causing Yamato to question his own humanity. As Hibiki defends an attack using Shakko's power, Yamato acknowledges him as an equal and reveals that their current situation had all been part of a grand scheme put into motion by Polaris since the moment of their births. However since Polaris itself is flawed by its own nature, it had left it up to humanity to decide amongst themselves who should survive until the end, whilst citing the anomaly of Alcor's nature as proof of this. This truth shocks Hibiki, but Yamato simply brushes it off as semantics in his goal to reshape the world into a meritocracy.
