Japanese history predominates a heavily structured plot, which mainly involves the continued aggression between magic using guardians, or "possessors," and the denizens of a "feudal underworld," or the restless souls of long-dead samurai attempting to re-ignite ancient war on the modern plane.

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. The rest of the world, None-the-wiser for the incident at the Biodome (which was covered up completely) has pretty much forgotten all about Dinosauroids.

Animal X: Genshi Sairai

Animal X―原始再来

The first series in the "Animal X" timeline.

27-year-old Ayukawa Yuuji has never been much of a man; he's more comfortable sewing than fighting, he faints at the sight of blood, and his fiancee is tougher than he is. He's also a terrible pushover. So when his boss at the medical lab volunteers him for some experimental drug therapy, how can he possibly refuse? All's mediocre for Yuuji: master of the pathetic.

Mediocre, that is, until a juvenile mass murder suspect jumps out from under Yuuji's bed, declaring him his "mate." Before Yuuji has time to argue, the stranger transforms into a 16 foot-tall dinosaur and beheads his roommate...

Yuuji suddenly finds himself the sole target of a lost race that turns into dinosaurs, an extremely scary woman with a Goddess-Complex, the yakuza, a mad scientist and one 17 year-old boy who really really really wants to sleep with him.
