From time immemorial, the spirits of nature created the Kamiga-kushi, a magical veil that hid them from the impure eyes of man. From then on, spirits and men could no longer gaze upon each other and lived as if belonging to separate worlds. One day, the Noggo appeared, and their darkness began to infect the world of the Kami. That's why the sacred tree, Munemori, created the Izuna, the only ones capable of battling the terrible scourge of the Noggo. But the mysterious birth of a wolf cub in the shape of a young girl threatens to upset the delicate balance between the two worlds.
