Yuuhi and Samidare meet the Dog Knight, Shinonome Hangetsu and grow closer to him, but Yuuhi grows very wary after watching him easily defeat a golem by himself with his power. Meanwhile, Samidare's father returns as Hangetsu is making moves on Hisame. After interacting with several kinds of "adults", Yuuhi recalls his dead father—

Yuuhi and the others celebrate Samidare's birthday and enjoy a moment of peace and calm, but Yuuhi also learns that Samidare is truly ill, and she's only able to be active now thanks to the Spirit, Anima. So once their battle is over Samidare's days will be numbered once more. Yuuhi finally tells Shinonome Hangetsu that he wants to become stronger, and Hangetsu agrees to help. Then Hangetsu begins to speak about his own past—

Samidare declares her intent to destroy the Earth and Yuuhi fights to protect Samidare as the Beast Knights fight to stop the destruction of the planet.

The Beast Knights bid farewell to their squires and go their separate ways before meeting up once again some time later in the future.
