Demon Slayer: The Nichirin Blade Turned Into a Demon, and Muzan Could Only Exclaim, “This Isn’t Right”

(No angst throughout) (Sabito didn't die) (Characters will never be OOC) (The protagonist transmigrates as the Nichirin Blade broken by the Hand Demon)

Muzan: I thought I was the demon, until I met that Nichirin Blade that can cut my neck without anyone even holding it. So who's the real demon here?!

Chen Lian transmigrated, but he didn't become a swordsman or a demon. Instead, he became the Nichirin Blade in Sabito's hands, the one about to break!

During the Final Selection on Mount Fujikasane, the Hand Demon cackled viciously as Sabito's strength gave out and his blade shattered.

A certain-death situation? Chen Lian snorted. “Who says a shattered blade can't slay demons?”

[Ding! Awakening: Indestructible Blade!]

That night, Sabito, who should have died, gripped a Nichirin Blade that would never break and cut the Hand Demon to ash with one stroke!

From then on, the Demon Slayer Corps had a monster in its ranks.

Sabito: “My sword has a will of its own.”

Muzan: “Has Yoriichi Tsugikuni been reincarnated? Why is that blade using Hinokami Kagura to attack me?!”

As a Nichirin Blade, Chen Lian has three outrageously powerful abilities:

1. [Indestructible Blade]: No matter how powerful your Blood Demon Art is, I won't budge an inch. My durability can evolve without limit!

2. [Soul Outside the Body]: The wielder falls? Chen Lian's soul manifests and takes over the battlefield!

3. [Blade in Body]: Replicate every Breathing Style in existence: Water Breathing, Sun Breathing, you name it!

When the battle at Infinity Castle begins, Chen Lian uses Soul Outside the Body to break free of human hands and behead Muzan on his own.

Muzan finally breaks down: “I'm the demon? No! That blade that can slay demons without anyone holding it is the real demon!”

In this life, beneath the Wisteria, everyone will survive!
