In an age when yokai, spirits, divine beasts, and evil demons coexisted, Seoritae, the greatest yokai hunter of Joseon, defeated the sinister puppeteer Jarigong, who had plunged the world into chaos by creating yokai, and brought about the extinction of these creatures.
Years later, now living under the name "One-Eye Park", a storyteller, he establishes the Divine Grass Garden to raise children born with yokai blood as virtuous beings.
In the present day, as yokai return and a massive conspiracy unfolds, a new war begins to protect the world once again.
