Demon Slayer: Kokushibo Killed Me Instantly from the Start, So I Turned into a Demon

Bai Chuan Juanzao transmigrates into Demon Slayer, with a god-tier script in hand from the start. He becomes Urokodaki’s disciple and Giyu Tomioka’s junior, and even has a “demon-eating” constitution comparable to Genya Shinazugawa’s. Low-ranking demons fall to his blade like vegetables beneath a cleaver. He thought he could steadily rise to the rank of Hashira, marry a rich beauty, and reach the pinnacle of life... Who knew he’d get carried away and run into Upper Rank One, Kokushibo, while hunting demons!

He’s killed in one blow. As he hovers on the brink of death, he takes Tamayo’s secret medicine and is reborn in a demon’s body.

“If the human body has its limits, then I’ll hunt demons as a demon!”

Now he lives in hiding under Tamayo’s protection, tempering his will with a Breathing Style and using his medical skills to keep his hunger for blood under control. The carefree young man with a bit of a loser streak has quietly grown into an unusual demon hunter, walking the line between light and darkness. When his Nichirin Blade is drawn once more...

“Muzan, I’ve been waiting a long time to strike you down with this blade.”
