Called the "Wise man of the woods" and given much respect by the villagers, messenger of heaven Olgrius is searching for the origin of the incessant outbreak of storms. Then a villager, speaking riddles of an attacking beast, appears.

The being that Olgrius sees when he returns to the scene of the crime is a savage beast fallen from heaven. But the beast differs from the rumors—he touches Olgrius gently, and protects him from danger...!?

The third series in the "Animal X" timeline.

Having burned enough bridges in Japan, Yuuji and Minato have moved their new family to a small dinosaur-crazy town in Canada. If there's any place in the world left for Dinosauroids, surely it must be here: a town revived by the discovery of dinosaur bones, with one of the largest paleontology research centers in the world, and a network of "Conservation Centers" set up to cater to the newly-discovered Dinosauroid community.
