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.

When a Tokyo teenager botches a suicide attempt, he finds himself recovering in a hospital where most of the patients are more than twice his age. Rejecting his mother's visits, he spends his time counting the hours between meals and blood-tests until a run-in with another teenage patient leaves him with an unlikely new friend.

A short story in 2 parts.

Taking refuge in the newly rebuilt Asato-Jima commune, Yuuji and Minato try to carve a place for themselves in a Dinosauroid society foreign to both of them. Split up for long periods of time by their work assignments, Minato and Yuuji slowly grow farther apart. When it seems as if nothing can possibly get any worse: Yuuji gives birth to his first child.

Six months later, a stranger comes to Asato Jima looking for work in the commune Research Lab. He's oddly interested in Yuuji and in learning information about a baby that no one on the island seems willing to acknowledge has ever existed...

Meanwhile, elsewhere on the island, the Blood come across the bodies of four of their own, slashed to death by the claws of another Dinosauroid. All eyes are quick to fall on the rebellious and possessive outsider, Minato.

Far away from home, Yuuji and Minato have carved a place for themselves in Alberta, Canada, with their new baby daughter, Yui. Yuuji works at a University, while Minato – though still as childish as ever despite being a new dad, works at the conservation center as a mediator for the better understanding between humans and Dinosauroids.

It’s been a year since the contagion called X Syndrome had been unleashed on the human race. Just as distinguished government officials and police force began to regain control of the situation, the existence of the Dinosauroids became known by the academic community. Dinosauroids – while they have a tendency to possess superhuman abilities, female births are extremely rare and problematic. Which is why the existence of Yuuji (a converted female Dinosauroid), and the newly born Yui are so valuable and sought after by many – most of whom wont hesitate to resort to dubious means to acquire either one of them!

True to words, Yuuji has indeed become the beauty as many had predicted – provided he takes off his heavy glasses of course! He is never short of admirers – both males and females, including a University student Linea, and the various Dinosauroid males eager to mate with a Dinosauroid female. And this is where the role of a female in a heavily populated male Dinosauroid society comes to play. Add to that, the various nefarious people after the newly born Yui, both the parents Yuuji and Minato might have their hands full this time around as well.

This is the third and final installment of the Animal X series.

Naruse Kunihiko is an upcoming short film-maker who shares the spotlight with no one. He writes his own scripts, his own music, and uses the one-man art of claymation to realize his vision onscreen.

So when he forms a friendship with Nakata, who has been assigned to interview him, Naruse finds himself unprepared for the trials of a real human relationship.
Meanwhile people who criticize Naruse have a way of "getting hurt". As Nakata finds himself drawn deeper and deeper into Naruse's world, he starts to suspect Naruse...
