Demon Slayer: I am a Demon.

"Infinite City"

A soft whisper suddenly broke the silence.

The next second, space itself seemed to turn upside down, and everyone in the Yoshiwara pleasure quarters, whether they were demons or swordsmen in the midst of battle, felt as if their feet had suddenly lost their footing.

The next second, I felt my body plummeting into a colossal underground city.

This is the Blood Demon Art: Infinite Castle, mastered by Nakime, the Upper Moon Four of the Twelve Demon Moons.

'Infinite Castle' is a Blood Demon Art from another dimension. The entire space of 'Infinite Castle' is centered around Nakime and is intricate. Nakime can manipulate the entire Infinite Castle by playing the biwa in her hand. She can bring any object into the Infinite Castle and teleport the object to any place within the Infinite Castle.

Nakime can manipulate the terrain of the Infinite Castle to deplete the enemy's stamina, making it difficult for them to approach her.

Of course, you can also hide people or stall for time.

While this Blood Demon Art isn't particularly lethal, it's incredibly annoying and difficult to deal with. Simply dragging Muzan Kibutsuji into the Infinity Castle will buy him enough time to break down the potion inside his body.

Even if the sun rises, as long as the 'Infinite City' exists, sunlight cannot penetrate into it.

Of course, ordinary Blood Demon Art cannot exist in sunlight, but 'Infinite Castle' is an exception. It's not that such Blood Demon Art can appear in sunlight, but rather that once 'Infinite Castle' is used, it will fall into an underground place where it can never see sunlight.

In the original future, Nakime's "Infinity Castle" Blood Demon Art caused considerable trouble for the Demon Slayer Corps, but also bought Muzan Kibutsuji enough time to break down the drug in his body.

If things had gone according to plan, everyone would probably have spent a lot of time and energy in the 'Infinite City'.

…………

He lost his footing and plummeted into a vast underground city space.

Looking at this densely packed underground city, Su Mu couldn't help but marvel at the power of Nakime's alternate dimension blood demon technique. No wonder Nakime, who had no offensive capabilities, gained Muzan Kibutsuji's trust and became the Upper Moon Four.

Previously, Su Mu would probably have been able to search within the Infinite Castle, slowly looking for Nakime's location or Muzan Kibutsuji's location.

However, by killing Kyokai, the sixth Lower Moon Demon, the Drum Demon, he also gained the Blood Demon Art from another dimension.

Looking at the underground city before him, Su Mu closed his eyes slightly and spoke softly.

"Blood Demon Art: House of Demons"

A house suddenly appeared out of nowhere.

If Kyōkai were still alive, even using 'Blood Demon Art: House of Demons' would not be enough to fight against 'Infinite Castle'. After all, Kyōkai was stripped of his position as one of the Twelve Demon Moons because of his talent.

But at this moment, it was Su Mu who was using the 'House of Ghosts' Blood Demon Art, and the 'House of Ghosts' he was using was far more powerful than Xiang Kai's.

As soon as the 'House of Ghosts' appeared, it began to expand rapidly, almost instantly swallowing up the surrounding area and spreading continuously. The 'Infinite City' also seemed to be putting up a fierce resistance at this moment, and the two were constantly fighting each other.

During the confrontation, Su Mu quickly located Nakime, who was manipulating the 'Infinite Castle' to fight against his 'Demon House'.

Step by step

Almost immediately, Su Mu arrived at a room and saw a girl holding a plectrum in one hand and a pipa in the other.

She had grayish-white skin, long black hair with bangs on both sides that completely covered her face.

At this moment, with Su Mu's arrival, the girl raised her head in shock, her eyes filled with terror as she looked at Su Mu.

"Nekome!"

Su Mu looked at the girl and said something in a low voice.

Nakime's expression changed drastically, and without even thinking, she turned to run away.

Behind her, a sharp blade flashed and landed on Nakime's head as she turned around.

"Crack!"

The sound of bones breaking rang out, followed by the sound of Nakime's head falling off.

As an Upper Rank demon, Nakime was killed almost without any resistance, showing no strength whatsoever that an Upper Rank demon should possess.

Su Mu was not surprised by this.

As an Upper Moon demon, Nakime was valued by Muzan because of the Blood Demon Art of the Infinity Castle. Apart from that, Nakime's own strength was actually quite average.

Chapter 293 The Death of Muzan Kibutsuji

After slaying the Upper Moon Four, Nakime, of the Twelve Demon Moons, the 'Blood Demon Art: Infinite Castle' was immediately destroyed, and the demon and swordsman who had just fallen into another dimension returned to the pleasure district of Yoshiwara almost instantly.

The feeling of spatial imbalance caused both the demon and the swordsman to momentarily lose their senses.

The moment the 'Infinite Castle' was destroyed and he returned to Yoshiwara, Muzan Kibutsuji, who had just hidden himself and was continuously breaking down the potion in his body, fled into the distance almost without hesitation.

Escape was once Muzan Kibutsuji's most powerful ability.

This was also what Muzan Kibutsuji was most proud of.

Back then, the swordsman Yoriichi Tsugikuni, who was comparable to a god or Buddha, severed his head almost instantly, almost immediately pushing him to the brink of despair.

But so what?

In an instant, he also split into 1,800 pieces of flesh. Even though Yoriichi Tsugikuni cut off more than 1,500 of them on the spot, some of the remaining pieces of flesh still managed to escape.

As long as even a single piece of flesh escapes, he, Muzan Kibutsuji, will not die.

That was the first time I had been driven to the brink of despair.

But so what if we're driven to the brink?

What good is Yoriichi Tsugikuni's swordsmanship, no matter how powerful he is?

Ultimately... it was impossible to really kill him.

Human lifespan is ultimately short; even the strongest swordsman can only live for a hundred years. He waited cautiously in the darkness for decades, until Yoriichi Tsugikuni was completely old and weak, and finally his opportunity arrived.

On that night of the red moon, Kokushibo, one of his subordinates, found Yoriichi Tsugikuni.

Even though the elderly Yoriichi Tsugikuni still possessed peak strength, what did it matter? In fact, the speed and power of his attack were no different from his prime, but he ultimately failed to deliver the blow. He simply maintained his standing posture and thus reached the end of his life.

Even the most powerful swordsman cannot withstand the erosion of time.

Therefore, even if another swordsman like Yoriichi Tsugikuni were to appear in the Demon Slayer Corps, he would be afraid, but he would never despair.

But at the moment.

For the first time, Muzan Kibutsuji felt despair.

At this moment, his ability to split apart, which he relied on, was completely suppressed by the Tamayo potion. He could no longer split into more than 1,800 pieces of flesh in an instant, just like when he fought Yoriichi Tsugikuni.

Moreover, this time, the person hunting him down was no longer someone whose life was as fleeting as a firefly.

Instead... it's a ghost.

You can sense that this is a demon that is constantly getting stronger. This failure may mean that it will hide in the darkness for the rest of its life and never have the chance to see the light of day again.

They didn't even have the chance to hide in the dark anymore.

For the first time, I felt a profound sense of despair.

…………

Running

Keep running

As the medication penetrated deeper into the body, human characteristics began to emerge, breathing became rapid, and the feeling of weakness intensified.

"boom……"

Having not adapted to the frail human body for too long, a sudden weakness in his legs caused him to lose his balance while running at full speed, and he fell to the ground.

"Ruined."

When this thought suddenly arose in Muzan Kibutsuji's mind, he raised his head.

The street ahead

Under the moonlight, Su Mu, holding a knife, appeared out of nowhere and was calmly looking at him.

Looking at this person, fear flashed in Muzan Kibutsuji's eyes. As she took a step back, she said with almost resentment, "We are all demons! We are all demons! Why are you standing with these demon hunters?"

Am I a ghost?

Su Mu looked at Muzan Kibutsuji and asked calmly.

"Is not it?"

Ghost Dance Tsuji. Muzan roared loudly.

Have I ever been a lover?

Su Mu looked at Muzan Kibutsuji and asked calmly.

"Who knows? But once you become a ghost, how can you possibly endure the desires of a ghost? No ghost can endure it."

"Yes! No demon can resist a demon's craving for human flesh."

Su Mu looked at Muzan Kibutsuji and said softly, "Back then, I was turned into a demon by you for no reason, and I had to endure the demon's craving for human flesh and blood..."

He said in a low voice, "But even so, I have been enduring it all."

He looked at Muzan Kibutsuji: "Even before I completely lost control, I was suppressing my bloodlust. To this day, I have never tasted a piece of human flesh."

Muzan Kibutsuji stared wide-eyed, unable to believe it.

Those who become demons by obtaining his blood—not a single demon can resist the instinctive urge for human flesh and blood, not even Akaza, whose obsession runs incredibly deep.

The wind blew gently, and the arriving butterflies listened to the conversation between Su Mu and Muzan Kibutsuji.

A pair of beautiful purple eyes looked at Su Mu, her expression filled with shock, complexity, and heartache... Shinobu Kocho, who deeply hated demons, naturally knew the extent to which demons craved human flesh and blood, but Su Mu, through his own willpower, endured it all.

At that moment, she remembered the promise she had made with her sister.

The moment Shinobu joined the Demon Slayer Corps, she made a promise to her sister to save the demons.

Yes, the idea of ​​saving demons was not understood by Gyomei Himejima at the time. In fact, she did not have the idea of ​​saving demons. Shinobu Kocho only hated demons and wanted to cut off their heads.

For so many years, she has had the thought of killing all the evil spirits every moment, longing to sever their heads and feel the tip of her knife pierce their bodies.

But there was never any idea of ​​saving ghosts.

But at this moment, for the first time, and very rarely, did he have the thought of saving a ghost.

……

"Not only have I never been a predator, but I can also bask in the sunlight. What makes you think I'm a ghost?"
