In the midst of the Heian period, on the southern isle of Shikoku, the Shyouhana family thought that they were safe from the affairs in Kyoto.  Their distant mountain village had been serene for generations, but that serenity, is soon to be lost.  As the summer solstice approaches, unrest fills the forest and rivers surrounding Odashizen Village.

The family decides that Sachiko, the eldest daughter of Natsuko and Mokuran Shyouhana, to venture out into the world to find the cause of the unrest, and to restore balance to Sankawayama.  Whom will she meet along the way, and will she be able to endure all of the challenges wrought upon the world by the Fujiwara Clan?

The kudan had given a warning about dark times to come.  The Shyouhana clan, while they did not doubt the kudan’s words, had no idea just how bad things would get.  The moryo of the forest and the three rivers of Mt. Tairyuji had become restless, leaving the inhabitants of Odashizen Village to wonder what the kami and yokai had in store for them that summer.
