Long ago, at the beginning of time, civilization live in harmony with nature. Many nature spirit blessed the anthros an ability to subdue the nature under their will. So they can conquer the mountain, the river, the sea and the forest to make their living.
But many nature spirits refused to relinquish their control over the nature. The benevolent ones simply ascended to another plane of existence so they can never bother or be bothered by the anthros. However, the malicious ones stayed on this plane, causing havoc and destruction whenever they wish.
Sensing the anthros peril, the highest spirit blessed a selected anthros and their descendants with the greatest blessing, a power to subdue the spirits itself. In exchange to this blessing, they were given responsibility to search and subdue the rogue spirits for the rest of their life or their power will be nullified. They are called Shamanist Tribes.
Foxy was the latest descendant of the Shamansist. 14 years old and he already shown incredible aptitude with his ability, even among fellow Shamanists.
Along with Chopper, the latest in line of the family that swore to accompany the Shamanist on their journey, Foxy set out on his Holy Crusade. Cleaning the world of malevolent spirits.
