On July 19, 2017, it was announced that Yamada's sequel, Basilisk: The Ōka Ninja Scrolls was green-lit for an anime and premiered on January 8, 2018.
For season one, the opening theme is Kouga Ninpou Chou by Onmyo-Za while the ending themes for the first fourteen episodes are "Hime Murasaki" by Nana Mizuki and "Wild Eyes" by Nana Mizuki.
Two ninja clans, Tsubagakure of the Iga and Manjidani of Kouga, battle each other to determine which grandson of Tokugawa Ieyasu will become the next shogun.
The deadly competition between 10 elite ninja from each clan unleashes a centuries-old hatred that threatens to destroy all hope for peace between them.
It is 1626 in the Kan'ei era, ten years after the fight for succession of the shogun, which pitted the Kouga and Iga ninja clans against each other.
