Moonlight Flowers

月下美人

Sugimoto, Ami

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.

As sole heir to the throne of Paros, Princess Erminia must accept the Sword and a husband when she comes of age on her next birthday. But the princess refuses to wed any man who is less of a man than she—which excludes every man in the kingdom!
