The second and third cours of Sengoku Youko, adapting the "Thousandfold Chaos" arc.

The chaotic aftermath of a confrontation between Jinka Yamato and Yazen results in the power dynamics between the magically gifted katawara and humans being turned upside down. As the news of the downfall of dangaishu—the katawara-hunting monks led by Yazen—spreads across the country, rogue groups of katawara start to form, worsening the already-fragile relationship between them and humanity.

An alcoholic Shinsuke Hyoudou now finds himself in the company of Senya, a former enemy of his who controls one thousand katawara within his body. Suffering from amnesia and unaware of his past life, Senya soon makes friends with a local village girl, Tsukiko. After a sudden surprise attack from a local god gone mad, this unlikely trio begin a new journey! Meanwhile, Tama Youko continues her search for the nine-tailed fox who now has the power to destroy the world: Jinka.
