A zoologist named Yamato Kazakiri discovers Zyuland. Zyuland is a world inhabited by an anthropomorphic animal race known as the Zyumans. Nevertheless, it overlaps with the entrance of the Dethgaliens from outer space who have chosen Earth to be the location of their 100th Blood competition. Four of the Zyumans – Amu the tiger woman, Tusk the elephant man, Sela the shark woman Sela, and the lion man Leo – try to defend Zyuland from the Dethgaliens. Their fight takes them to Earth, with Yamato, and along with the Champion's Proof, the fifth of a set also possessed by his Zyuman companions. The Champion's Proofs transform into devices that transform them into the Zyuohgers. After the battle, the Zyumans realize that they are now trapped in the human world, as there needs to be six Champion's Proofs for them to return to Zyuland. Yamato helps the four Zyumans live in the world while they search for the sixth Champion's Proof, meanwhile enduring the Dethgalien battle who have added the Zyuohgers to their Blood Game festivities. The invaders kidnap the human Misao Mondo and transform him into an artificial Zyuohger to fight in their stead. However, once the Zyuohgers release Misao from the Dethgaliens' control, he joins their side as Zyuoh The World. While Bado, an old acquaintance of Yamato's family, later uses the sixth and final Champion's Proof to join the fight as Zyuoh Bird.
