In this world, the war between humans and ghosts has lasted for thousands of years.
For generations, the Ubuyashiki clan has led the swordsmen of the Demon Slayer Corps to hunt evil spirits in the world. Groups of ghost hunters walked out of Fujisui Mountain, and groups of ghost hunters fell on the road to defeat ghosts...
Ubuyashiki Yōya is known as the wisest leader in the history of the Demon Slayer Corps. However, in the ten years he has been in power, the Demon Slayer Corps he leads has never had any ghost hunter who can truly threaten the ancestor of ghosts - Muzan Demon Slayer!
Until one sleepless night, he suddenly remembered that before he was blind, he had seen such a yellowed record in the biography of the head of the Ubuyashiki clan passed down from generation to generation:
"When the immortal swordsman named 'Zuo Chuan' pulls out the Nichirin Sword he buried underground, the world will tremble, and the painful howls of the evil spirits will reach the deepest hell!"
