Simultaneous Transmigration: From Japanese Anime to American Comics

Finally, the cracks completely disappeared, replaced by a forest that had unknowingly taken over most of the battlefield.

Atop the largest tree, which would require dozens of people to encircle, a figure became clearer under the moonlight.

The figure carried something resembling a coffin in one hand and a severed head in the other.

The head had a massive eye dominating its face, filled with terror.

Daki, who had been gloating just moments ago, recognized the head and screamed in shock, "Nakime!"

"Oh, you recognize her? Then let me give this to you!"

The head of Nakime was thrown, only to disintegrate into ash mid-air before Daki could catch it.

Kokushibo looked up, his face darkening. He didn't see the familiar figure he expected.

It wasn't Muzan Kibutsuji!

The battle inside the Infinity Castle had ended.

Nakime was dead.

But the person who emerged wasn't Muzan Kibutsuji.

The meaning was clear to every demon present: they had lost—completely lost. From now on, there might never be demons in this world again.

"Hahahaha!!!"

Kagaya Ubuyashiki slammed his hand against the railing he was leaning on, laughing freely for the first time. If one listened closely, they could hear a faint sob in his laughter.

His laughter echoed across the battlefield, sharply contrasting with the arrogant laughter of the Upper Moons just moments before.

"Stop laughing! You disgusting human, you filthy maggot!" Daki completely lost control, spitting venomous curses. If she could, she would tear that man's mouth apart right now.

But in the next instant, Uzui's Nichirin blade cut through the night sky, its brilliant silver light precisely decapitating her, silencing her curses.

Though Daki wasn't dead, she was too frightened to speak.

Unless both siblings were beheaded simultaneously, one would always revive the other. Otherwise, Daki would have died hundreds of times at Uzui's blade.

The next to break down was the cowardly Hantengu.

His Blood Demon Art spiraled out of control, resulting in a complete rampage.

Four emotion-based clones merged into one, and the ultimate form appeared.

Zohakuten!

Meanwhile, the original body, Urami, transformed as well, growing larger and more ferocious. His once fearful expression twisted into a menacing snarl, his blood-red eyes glowing, and a faint "Resentment" character engraved on his tongue.

This was Hantengu's final form—Resentment Demon, his last resort.

Driven by survival instinct, Hantengu unleashed his full power.

Sanemi Shinazugawa and Kanae Kocho, who were responsible for fighting him, suddenly found themselves under immense pressure.

Zohakuten and Resentment Demon could use all the abilities of the previous emotion clones. In essence, Sanemi and Kanae were each fighting multiple opponents simultaneously.

Each of them was now facing multiple enemies at once.

Just as the situation reached a critical point, Gyomei Himejima, Rengoku Kyojuro, and Giyu Tomioka all joined the battlefield.

They no longer had to fight Kokushibo.

Because the one to deal with Kokushibo had returned.

At this moment, Kokushibo's mind was no longer on those three.

Enraged beyond reason, Kokushibo's six eyes fixated on the tree coffin that Chu Yang was carrying.

He had a strong sense that Muzan Kibutsuji was inside.

Kokushibo believed he hadn't lost yet.

If he could defeat the man carrying the coffin and free Muzan, victory would still be theirs.

And so, Kokushibo charged at Chu Yang with ferocity.

It wasn't that Chu Yang wanted to keep Muzan alive; it was that he truly couldn't kill this monster with five brains and seven hearts.

The Muzan of today was different from the Muzan of centuries ago. His regenerative abilities had reached a point where even the Sun Breathing techniques could not completely overcome them.

No matter how many times Chu Yang tried to kill him in the Infinity Castle, Muzan's terrifying regeneration allowed him to revive at the last moment. This was why Muzan had managed to stall Chu Yang for so long.

Chu Yang realized he couldn't finish off this creature.

To truly kill Muzan, he had to wait for daylight and let the sun burn him to death.

To prevent Muzan from escaping like he had done centuries ago, Chu Yang sealed him in the tree coffin.

The effect seemed to be working.

Kokushibo dashed up the tree trunk with astonishing speed, heading straight for Chu Yang.

This strange being, despite becoming a demon, still fought as a swordsman. He was the only one among the Twelve Kizuki who used the Breathing Styles.

If Muzan's godlike regeneration weren't factored in, Kokushibo's sheer offensive power was not inferior to Muzan's.

Kokushibo could still fight while in his Marked state.

Even the strongest Demon Slayer Hashiras would fare no better against Kokushibo than they would against Muzan.

But unfortunately for him, Kokushibo's opponent this time was Chu Yang. No matter how powerful Kokushibo's attacks were, they couldn't penetrate Chu Yang's Armament Haki.

The moment Kokushibo reached the top of the giant tree, his Nichirin Blade, Kyokokukamusari (Hollow Cry of the Godless), underwent a transformation.

The blade, resembling living flesh, squirmed and extended, growing longer with many sharp edges emerging from it.

As a weapon Kokushibo forged from his own flesh and bones, this was the true form of Kyokokukamusari.

It was only then that Himejima and the others realized...

Kokushibo had been holding back during their fight.

When Kokushibo unleashed his full power, an overwhelming aura emanated from him, suffocating all who were present, even from a distance. This sent chills down everyone's spine.

Chu Yang stretched his muscles, a glimmer of pleasure flashing in his eyes. Compared to an opponent like Muzan Kibutsuji, who could endlessly regenerate, he much preferred fighting a berserker-type opponent like Kokushibo.

"Hoo~"

Chu Yang exhaled softly, his breath transforming into golden flames that soon enveloped his entire body, making him appear like a sun descending to the mortal world.

The brilliance radiating from Chu Yang was so blinding that many demons on the battlefield mistook it for daylight. In a panic, they tried to flee, only to be cut down by the Demon Slayer swordsmen led by Sakonji Urokodaki.

Even the Lower Moons suffered casualties.

Despite facing such an overwhelming opponent, Kokushibo did not retreat. Instead, he resolutely charged at Chu Yang, launching an attack.

The greatest regret in Kokushibo's life was living in the shadow of Yoriichi Tsugikuni. Even after becoming a demon and breaking the curse of the Mark, he still lost to Yoriichi, who was in his twilight years.

To lose to a man who was already at death's door was the ultimate irony for him.

Kokushibo had become this grotesque form solely to surpass Yoriichi, but Yoriichi took the victory to his grave. This meant Kokushibo could never fully erase his defeat and truly surpass him.

Now, Chu Yang, a practitioner of the Sun Breathing, stood before him, radiating a familiar, blinding light. Killing Chu Yang would, in Kokushibo's mind, be equivalent to finally defeating Yoriichi.

At this moment, Chu Yang was the only thing in Kokushibo's eyes, even as the tree coffin holding Muzan slowly faded from his sight.

Time and space seemed to slow for Kokushibo. He saw Chu Yang's flame-wrapped sword swinging toward his neck.

Kokushibo raised his blade to meet it, also aiming for Chu Yang's vital point.

The two blades did not collide but instead narrowly missed each other, both slicing into the other's neck!

Kyokokukamusari clashed fiercely with Armament Haki. The flames surrounding Chu Yang and the flesh on Kokushibo's blade gnawed at each other. In the end, the flesh disintegrated, and Kyokokukamusari shattered.

At the same time, Chu Yang's sword severed Kokushibo's neck, sending his head flying high, an expression of shock frozen on his face.

Why couldn't Kyokokukamusari sever his neck? He's merely human, right?

Kokushibo couldn't comprehend it.

If Doma and Akaza were still alive, they might have been able to explain why.

Once again, Kokushibo felt that he had lost.

Once again, he had lost to the Sun Breathing! Once again, he had lost to Yoriichi Tsugikuni!

Even after paying such a heavy price!

After becoming a hideous demon for centuries, why was he still losing to that man?

If I could break through my limits, would I be able to defeat the enemy before me?

With that question lingering, Kokushibo glanced at Chu Yang.

He stood amidst layers of flames, exuding a terrifying aura, like a god.

Even if I tried again, I wouldn't be able to sever his neck…

With that answer, a bitter smile tugged at Kokushibo's lips as his consciousness slowly faded into darkness.

His body erupted into a fierce blaze, instantly turning to ash.

At the moment of Kokushibo's death...

The last shred of hope in the remaining demons was utterly crushed.

As Chu Yang's gaze swept over them, it felt as if the sun itself was scorching their bodies.

The demons were in complete disarray, trying to flee, but they were trapped by the eerie forest, unable to escape the battlefield.

The remaining Twelve Kizuki were cut down one by one by the Hashira, united in their final stand.

The battle was over.

A faint red glow appeared on the horizon, blending with the golden flames surrounding Chu Yang.

The sun had risen.

"Ahhhh!!!"

"It hurts so much!"

"Save me, I don't want to die!"

"I was wrong, I was wrong!"

The agonized wails of countless demons echoed over the Demon Slayer Corps' headquarters, but none of the swordsmen found it bothersome. Their eyes brimmed with tears as they silently mourned their fallen comrades and loved ones.

It was all over...

There would never again be demons in this world.

Chu Yang carried the tree coffin to the center of the battlefield, placing it down under the watchful eyes of everyone, and slowly opened it.

"Muzan, time to bask in the sunlight!"

As soon as he spoke, a dark figure burst from the coffin. Warm sunlight fell upon it, and a pained scream followed—a sound so satisfying to hear.

Muzan Kibutsuji's powerful regenerative abilities prevented him from being killed by sunlight as quickly as other demons, significantly prolonging his suffering.

Kagaya Ubuyashiki, supported by his wife, silently watched as Muzan was burned by the scorching sun. He spoke softly, "Does it hurt? The pain you feel now is the pain that every generation of the Ubuyashiki family has endured."

"We were cursed because of you, born in pain and destined to die in pain."

"Countless innocent people have also died because of you—those who refused to become demons and yet were turned into demons in the end. How much pain did they endure?"

"Feel this pain well, and never forget it, even in Hell."

Muzan glared angrily at Kagaya.
