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—

The Spirit, Anima, appears and gathers the Beast Knights together to transform Dance Dark into the Mythic Beast Knight, Unicorn, leaving the knights to face a new golem without Samidare once more.

Subaru and Yukimachi recall their wish and their meeting with their Beast Squires while Taiyou grows closer to the eleventh golem, Maimakterion.

Pyanepsion and Maimakterion, the tenth and eleventh golem, fight together to corner the Beast Kngihts before being driven off and Taiyou finds himself opening up to the older Knights.
