Reborn in Demon Slayer: The Strongest Demon King

Ji Xiu dies in a car accident and is reincarnated in the world of Demon Slayer as the strongest Upper Rank: Kokushibo.

On the first day after his reincarnation, he slays Doma and saves the Butterfly sisters.

On the second day, he erects his own tombstone...

The transmigrator should have had an overwhelming advantage, but here, that advantage is nowhere to be found.

To break free of Iwakatsu Tsugikuni’s will, he has no choice but to pursue the path of becoming the strongest in history.
