A young worker joins Sylphon Co., a multi-billion dollarth corporation in hope for a better living. Cutting down trees to improve the economy of the greatest city in the world as a proud patriot, and to gain a few more coins in his pocket, Rex did not argue with that. However, weird things began to happen when he saw a beautiful creature made of wood appear in front of him. Losing himself to the temptation, he decides to follow her into the forest and ends up losing himself where he discovers a world meant to be forsaken to mankind. Eventually, he meets talking animals hostile to all humans and his ethereal creator, Mother Nature. Learning of the goddess' dilemma, Rex embarks on a quest to save the forest from destruction from mankind's foul plots. Rex ends up betraying his own kind to join the forces of nature and to fight for a good cause, meeting perils along the way and restoring animal's trust in humans as he tries to find the lovely creature he had fallen in love with.
