In the past, people and animals lived in harmony on their own continent. Humans inhabitable the great continent called Asalea and animals lived on a small neighbouring continent called Utopia. Among the humans, the Indians, an indigenous people served as mediators between the two species.

But one day, following a disaster, Utopia disappeared, taking with him a large part of the animals and Indians. Today, Asalea is populated by humans and the last living animals. In order to control the most dangerous animals, humans have developed superhuman abilities called Redskins.

Thanks to their skills, the Redskins have been able to develop a prolific trade in the animal sector. Agatho, one of the last living Indians, is a Redskin unlike any other.
