Second season of Hiiro no Kakera.

In Ibana, the so-called "Red Nation," there lives a mythical creature known as the Red Fox—said to take on human form and steal human livers. Though the legend of the Red Fox has long faded into obscurity, the world is once again thrown into chaos with its sudden reappearance. At the heart of this turmoil stands the princess of the Red Nation named Sana.

Young boy Amon has mysterious powers. His dad is the cheif scientist for the Empire of the Golden Snake. He's invented weapons for this country in the past, but does not want his boy's powers to be used for destruction so he burns his research and tries to escape the country with his family. The mom and dad die in the escape and only Amon is left. He runs from the military, ends up on an island where he learns about the ancient people who could fly on the wind and talk to animals (as he can). Amon then ends up in a fishermen's village and makes friends with Maria. After this village is attacked by the Golden Snake army, the two run away with a band of rebels. Together, they try to stop the Empire of the Golden Snake from destroying and conquering everything. Based on the book by C.W. Nicol.
