Chapter 13: Muzan Alertness

In Kotori Itsuka vision, Ratatoskr is an organization that can accommodate both humans and demons.

Although the three demons who have joined the organization so far are not controlled by Muzan Kibutsuji for various reasons, these three are probably the only demons in this world who are not controlled by Muzan Kibutsuji.

If you want other Demons to join Ratatoskr, you need a way to prevent them from being troubled by the curse.

Tamayo potion is indeed effective. She herself is an example of someone who got rid of the curse by taking the potion continuously, but it takes too long to remove the curse.

Even if there are Demons willing to join Ratatoskr, they will need long-term recuperation before they can be considered true members.

And when they removed the curse, I'm afraid Kotori Itsuka would have left this world long ago.

That's why she needed a faster way to remove the curse.

Using her own self healing flame to fight the curse was the solution she came up with in a flash of inspiration.

Fortunately, this method did succeed.

Looking at the Demons in front of her that was no longer troubled by the curse, Kotori Itsuka mood became happy.

However, at this moment, the basement door was opened.

Looking back, Tamayo, Yushiro, and Tanjiro Kamado all came down.

The first two didn't even have time to take off their white coats. It seemed that they had hurriedly put down their work and rushed over while conducting research.

"What just happened?"

Tamayo eyes moved back and forth between Kotori Itsuka and the Demons on the operating table, and she asked tentatively: "We could clearly hear the scream just now on the second floor. What did you do to this patient?"

"Don't get me wrong, I have no interest in abusing anyone."

Noticing the suspicion in everyone's eyes, Kotori Itsuka said calmly: "I just did a small experiment on this person. The experiment went smoothly and everything is fine now."

"Experiment? What experiment?" Yushiro eyebrows twisted. "This is our patient. His family personally handed him over to us for treatment. Don't do any weird experiments."

"An experiment to help him remove the curse."

Kotori Itsuka took a step away and made a gesture of invitation: "The curse of the Muzan cells in his body has disappeared, of course, thanks to me."

Hearing this, everyone was stunned.

Tanjiro Kamado was okay, as he didn't know much about curses.

But for Tamayo and Yushiro, who specialized in curses, this was simply unbelievable.

In this world, apart from Muzan, there is probably no one who knows the curse on Muzan cells better than them.

It took Tamayo hundreds of years to develop the medicine to eliminate the curse, and it also took her several years to completely eliminate the curse from her body.

Even if the man lying on the operating table had not been a demon for long and the Muzan cells in his body were not yet stable, the speed of removing the curse would be much faster, but it would be impossible to completely eliminate it within a few minutes.

However, when Tamayo looked at the unconscious man, her gaze changed.

The curse that was originally clearly felt in the other person's body could no longer be felt at this moment.

Just as Kotori Itsuka said, it disappeared completely.

"What did you do to this gentleman?" Tamayo asked curiously, "What method did you use to eradicate the curse in such a short time?"

"It's simple. I exhausted the power of the curse, and the curse naturally dissipated."

Kotori Itsuka did not hide anything and stretched out a hand, and the purple self-healing flame appeared in her hand.

The reason why demons are killed by curses is essentially because once the curse attached to Muzan cells is triggered, it will control Muzan cells to kill the host.

The recovery ability of demons comes entirely from Muzan cells. Once Muzan cells are controlled, they lose their recovery ability.

Without their powerful recovery abilities, the only fate that awaits them is death under the curse.

But Kotori Itsuka self-healing flame solved this problem.

The Demons's body will be destroyed by the power of the curse, and repaired by the power of the self-healing flame.

This process is extremely painful.

Ordinary humans would never be able to endure it. Even Pillar-level members would not be able to withstand the extreme output of the Self-Healing Flame.

Only Demons with thick skin and flesh can withstand it.

After telling everyone about the self-healing flame and how he removed the curse, they understood why the curse disappeared.

This made Tamayo a little disappointed.

After all, this self-healing flame is an ability that belongs to Kotori Itsuka. In her eyes, it is almost the same as blood demon magic and there is nothing to learn from it.

However, even if it cannot be used as a reference, it is good to have one more way to eliminate the curse.

"Leave the task of taking care of him to me first."

Coming to the unconscious man, Tamayo checked his physical condition.

"If he can recover, maybe Ratatoskr can welcome a new member."

At the same time, in a mansion somewhere in Tokyo.

In a laboratory filled with various equipment, a young child with black hair and red eyes who was doing an experiment raised his head as if he sensed something.

In those eyes that seemed to be made of solidified blood, a trace of doubt flashed across them.

The child's name is Yamazaki Chio.

The adopted son of the chairman of Yamazaki Pharmaceutical.

However, this identity is just one of his many identities.

With the ability to control his body at will, he can appear in front of the world in various appearances.

His real name is Muzan Kibutsuji.

"The power I left on that man has disappeared." Muzan Kibutsuji muttered to himself, "How strange."

A few days ago, his identity was exposed by a member of the Demon Slayer Corps in Asakusa.

In order to create chaos so that he could leave calmly, he injected his blood into the body of a passerby, making him his follower.

As the ancestor of all Demons, Muzan Kibutsuji can feel the power he leaves in the body of each Demons.

Or rather, a curse.

With the power of this curse, he can easily control the life and death of Demons, locate the position of Demons, listen to the voices of Demons, and even share the five senses of Demons.

Just now, he felt the curse in the Demons he left in Asakusa disappear.

And it disappeared in an extremely strange way.

"It doesn't look like he was being conquered..." A strange light flashed in Kibutsu eyes, "What happened?"

Generally speaking, if the curse disappears, it means that the opponent has been killed by the Demon Slayer Corps.

In that case, the curse will dissipate immediately.

However, he clearly felt that the curse he had left on the passerby was disappearing at an even speed.

It was as if it was dissipating bit by bit due to some external force.

This feeling gave him an ominous premonition.

"Asakusa? Looks like we need to investigate."

Muzan Kibutsuji looked out the window towards a certain direction of Tokyo and muttered to himself.

"But the Demon Slayer Corps seems to be keeping a close eye on us recently. I can't go there myself, so I'd better let someone else investigate."
