"Tribal Manifestation" takes place in a rural world ran with little technology. Civilzation is divided by many small tribes constantly at war to expand their land. Each human is born with a "gift" that is unlocked upon reaching the age of 19. In order to discover the depths of their gifts, humans make their way to the neutral zones in their world placed by the "Watchers". Near the home of the Ardent tribe is the entrance to a colossus tower known as "Ignas" that is as wide and tall as the eye can see. This story follows Inarashi of the Ardent tribe; son of the warchief, Silva. Two years ago Silva entered Ignas with his wife, Ignacia, to never return. Inarashi is now turning 19 and ready to discover his gift, hoping to be a worthy successor to his father, Silva.
