Yuuhi returns home to face his grandfather. His sick grandfather reveals that his feelings have changed from what he thought in the past, and he apologizes for all that he's done to Yuuhi. The sight leaves Yuuhi extremely distressed and angry. As he faces all that, Yuuhi is once more attacked by a new golem. This time he must fight it without any hope of rescue from Samidare.

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—

Yuuhi struggles to cope with Hangetsu's death and actually fight as new Beast Knights appear before him and Samidare, and band together to face the next golems.

Hangetsu's wish has both made Yuuhi stronger and made him a target for Mikazuki while the rest of the Beast Knights are brought together.

With the survivng ten Beast Knights now united, Yuuhi learns of Nagumo's past as a detective while Shimaki converses with Animus in his dreams.

Yuuhi digs up a box buried in the mountains that contains a letter and a book for him which describes the life of the clairvoyant Swordfish Knight, Akitani Inatika.

Samidare and Yuuhi help training Tarou and Hanako, however, there doesn't seems to be any progress. Mikazuki calls Yuuhi and tells him that its summer and that is associated with beaches and swimsuits, and that they should held a training camp.

Samidare runs away from home to avoid her Mom, so Yuuhi is forced to live with the Asahina family while she stays at his apartment.

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.

The eleven-eyed, shapeshifting golem appears before the Beast Knights as they grieve their loss of Kusakabe Tarou, and they gather forces to avenge him.

Mikazuki introduces Yuuhi to the job he inherited from Hangetsu, and after reminiscing about him, they agree to duel.
