Amamiya Yuuhi, an average college student, wakes up one morning to the sight of Neu Crescent, a talking lizard claiming to be a knight. Neu asks for him to help save the world and protect their princess from an evil mage seeking to destroy the Earth, but Yuuhi finds it hard to believe such an absurd request. However, later that day a golem created by the evil mage appears before Yuuhi. Yuuhi is about to die when suddenly—

Yuuhi learns of the reason Samidare wishes to destroy the Earth, and he continues to train himself every day in order to hone his new powers. However, the "discipline" Yuuhi received from his grandfather continues to bind him like cursed chains. During that time, Yuuhi receives word from his home that his grandfather has fallen ill and been hospitalized—

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.

Shimaki struggles to create his next golem, and Yuuhi must face Anima's trial after dealing with the death of his grandfather.

While Samidare and Yuuhi are absent, Maimaketerion challenges the Beast Knights and wins, only to delcare that it will appear again in ten days and go after their families if they don't provide a better fight then.

Anima and Animus were the sole survivors of a space shuttle accident in the distant future, but their secret leads to the battle over Earth's destruction, and after many years Anima finally meets the young Yuuhi and Samidare.

The Beast Knights face Animus and his final golem in the last battle as the Biscuit Hammer finally activates.

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