Sunday of Realization - I - S1.E12

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.
