Chapter 253

Karl glanced at Tanjiro and said with a smile, "Don't mention it, let’s meet again sometime." "Okay, goodbye!"

Just as Karl was about to leave, he saw Nezuko, who had a dazed expression, and suddenly spoke.

"Tanjiro, do you want to cure your sister?"

"Ah?"

Tanjiro was stunned, and then his heartbeat suddenly accelerated.

Finding a way to turn his sister back into a human was the driving force behind everything Tanjiro did.

Even his grueling training and joining the Demon Slayer Corps were for this reason.

The ultimate goal of everything he did was to turn his sister back into a human.

Unfortunately, until now, he still had no leads.

Now, Karl had suddenly asked this.

A thought that was hard to believe formed in Tanjiro’s heart.

That was, could Karl possibly cure his sister?

It wasn't entirely impossible!

After all, Karl himself was a person from another world.

Such an existence was already very miraculous.

Coupled with the ease with which Karl had fought the Twelve Kizuki and the nine Pillars earlier,

it was certain that Mr. Karl possessed incredibly powerful strength.

So.

Since it was an existence like Mr. Karl, perhaps it wasn't entirely impossible to cure his sister.

Tanjiro swallowed, his voice trembling, "I want to... of course I want to cure Nezuko. This is my lifelong wish!"

"Mr. Karl, do you have a way?"

"I do have a way."

Karl replied, "However, after the treatment, she will forget everything that happened during the time she was a demon. She will return to the state she was in before becoming a demon, both physically and mentally."

"Is that okay?"

His treatment involved using the power of time.

To restore Nezuko Kamado’s body to how it was two years ago, when she was still a human.

Naturally, memories of the time she spent as a demon could not exist.

If Karl remembered correctly, according to the plot of *Demon Slayer*, Nezuko would eventually return to being a human anyway.

It was better to make this clear beforehand.

"Of course!"

Tanjiro said excitedly, "That’s not a problem at all, as long as Nezuko can recover!" "Hmm."

Karl nodded, then glanced at Nezuko.

Tanjiro stood where he was, looking at Karl with full expectation.

He was very curious about how Karl would cure Nezuko.

However, to his surprise, Karl did nothing.

Several seconds passed, and it remained the same.

Tanjiro was a bit curious; wasn't Mr. Karl going to cure Nezuko?

Why wasn't he taking action?

"Where... is this?"

"Brother?"

At this moment, a crisp voice rang out. CHAPTER 1000

"Where... is this?"

"Brother?"

Just as Tanjiro was wondering how Karl would cure Nezuko. CHAPTER 1001

A crisp voice suddenly came from the side.

!!!

When Tanjiro heard this voice, he was suddenly stunned.

This voice, he had heard this voice countless times before.

This was Nezuko’s voice!

Could it be... that Nezuko had recovered?

One must know that ever since Nezuko became a demon, she hadn't spoken a word.

Of course, she had actually spoken once.

During the battle against the Twelve Kizuki, Lower Rank Five Rui, she had said one sentence.

But that was the name of a technique, and Tanjiro had been fighting with all his might at the time and hadn't noticed.

Tanjiro slowly turned his head to look in the direction of Nezuko.

He saw that the bamboo muzzle she had been holding in her mouth was now in her hand.

Nezuko was looking around with some surprise.

That expression was different from the dazed look she had when she was a demon.

Tanjiro knew.

That was the way Nezuko looked before she became a demon.

"Nezuko!"

Tanjiro ran over excitedly and hugged Nezuko, weeping bitterly.

For over two years, he had hoped for his sister’s recovery every single moment.

To find a way to cure his sister, Tanjiro had practiced diligently, transforming from an ordinary boy into a powerful swordsman.

The boy who used to tremble at the sight of a demon had now eliminated many evil demons.

The boy had become much stronger and would not retreat even when facing difficult predicaments.

But at this moment.

Seeing Nezuko recover, he still couldn't help but weep uncontrollably.

"Brother..."

Although Nezuko didn't know why her brother was crying, nor did she know where she was,

seeing her brother crying so hard, she didn't say anything, but quietly and gently patted his back.

"..."

Seeing this scene, the Pillars were shocked.

As the most powerful swordsmen, they could naturally distinguish between demons and humans.

Before, Nezuko was undoubtedly a demon.

And it was precisely because Tanjiro was traveling with a demon that he was brought to headquarters.

The experiment could only be done in a room.

This was because demons could not see the sun.

Once exposed to sunlight, a demon would turn to ash.

Therefore, they could not go out during the day.

But now.

The Pillars all noticed the change in Nezuko.

She was no longer a demon, but a human.

But how could this be possible?

Could a demon turn back into a human?

Such a situation had never occurred before.

Moreover, this change seemed to have been caused by the person who killed the Sound Pillar and Wind Pillar.

Yet the Pillars hadn't seen how Karl had done it at all.

This person clearly hadn't made any movements! CHAPTER 1002

Was it really him who did it?

Had this demon really turned back into a human?

Even though they felt that Nezuko Kamado was no longer a demon, the Pillars still found it hard to believe.

Many of them even wanted to let Nezuko go out to see the sunlight.

To test whether she was a human or a demon.

However, with someone like Karl present,

they really didn't dare to force Tanjiro and his sister.

Because the Master was blind, he didn't know what had happened.

But that didn't matter; at his sides were two silver-haired girls.

These two girls looked almost identical; in fact, they were twin sisters.

And.

They were the Master’s daughters, Hinaki Ubuyashiki and Nichika Ubuyashiki.

Because the Master was physically weak and plagued by illness,

he needed others to assist him.

These two twin daughters were naturally the most suitable candidates.

Hinaki Ubuyashiki tugged on the Master’s clothes.

The Master lowered his head, and the girl whispered something in his ear.

!!

As soon as she finished speaking, the Master’s expression changed.

What Hinaki Ubuyashiki had said was that Nezuko had recovered and become a human.

Even with the Master’s status and broad heart, he could not remain calm.

His expression changed instantly.

As the Master of the Demon Slayer Corps.

And even someone who had a blood relationship with Muzan Kibutsuji,

he had never heard of anyone who had become a demon being able to recover.

No one knew this better than he did.

The same was true for the nine Pillars.

Therefore, the shock he received

was far greater than that of the nine Pillars, or even Tanjiro.

Karl looked at Tanjiro and his sister, smiled softly, and prepared to leave.

He didn't want to disturb this heartwarming moment.

"Karl... Mr. Karl."

However, at this moment, a trembling voice came.

It was not Tanjiro’s voice.

It was...

The Master, Kagaya Ubuyashiki.

Karl was a bit surprised that this person would call out to him.

After all, he was completely unfamiliar with this person.

"What is it?"

The Master asked, "May I ask... did you turn Nezuko, who was a demon, back into a human?" "That’s right."

"..."

He hadn't expected Karl to actually admit it.

The Master was silent for a moment, then asked somewhat anxiously, "May I ask, how... how did you do it?" "I just did it."

Karl replied, "Do you want to save people?"

"It’s a pity that this method is something only I can use in this world." CHAPTER 1003
