I don't want to be an elf!

Finally, there are his bones.

As the progenitor of all demons, he can be reborn as long as even a trace of his Muzan cells remain.

However, even his self-healing ability couldn't keep up with the speed of destruction within this all-consuming beam of light.

His roars and wails came to an abrupt halt.

Under the destructive power of Kotori Itsuka's strongest attack, a cannon shot whose destructive power ranks among the top of all the abilities of all the elf girls, everything he had turned into nothingness.

Not even ashes remained.

Having created the perfect opportunity to deliver the final blow, Gyomei Himejima and Kyojuro Rengoku stared blankly at Muzan Kibutsuji disappearing into the flames, unable to recover for a moment.

"it's over......"

As Rengoku Kyojuro's muscles relaxed, the tattered Nichirin Blade fell to the ground.

As he felt the evil aura completely disappear, Himejima Gyoumei clasped his hands together, tears of joy streaming from his eyes.

Muzan Kibutsuji is dead.

The original demon, the absolute ruler of demons, the monster that wreaked havoc on the human world, finally received his judgment and met his end.

The long-cherished wish of the Demon Slayer Corps to carry on its legacy has finally come to an end.

"Is that the end?"

Looking at his torn body, Upper Moon One, Kokushibo, slowly lowered his Nichirin Blade.

The other Upper Moons also sensed their bodies breaking down, some with complicated expressions, others bursting into tears.

If Muzan Kibutsuji dies, they will die too.

As the Muzan cells within his body lost their master, the curse attached to them erupted, causing the Muzan cells to lose their activity.

Without the support of Muzan's cells, the demon's body could no longer be maintained.

In less than ten seconds, the five Upper Moons present also vanished into thin air along with their master.

It's not just about winding up the arms.

All the demons in Japan are like this.

The long-standing war between humans and demons came to a perfect end with that cannon shot that pierced the sky.

"we won?"

Exhausted, Tanjiro Kamado plopped down on the ground, muttering to himself in a daze.

The successful defeat of Muzan Kibutsuji not only fulfilled the Demon Slayer Corps' long-cherished wish, but also achieved his own objective.

Although he didn't kill them with his own hands, he and Nezuko made significant contributions to the campaign, which can be considered as avenging their fallen family members.

His battle ended here.

The battles belonging to all the Pillar-level members also ended here.

At that moment, everyone present stood silently in place, as if they were dreaming.

"Kotori?"

As Rengoku Kyojuro's panicked voice rang out, everyone snapped out of their daze.

Following Rengoku Kyojuro's gaze, they were all taken aback.

Because the Balrog of Ratatosk, the greatest contributor to this campaign, has now become transparent.

It's as if they've lost the very foundation upon which they exist in this world, and are gradually disappearing.

At this moment, Kotori Itsuka, whose eyes were bloodshot and affected by the berserk state, now had a clear mind.

The moment the main quest was completed, the system notification page appeared before her eyes as usual.

All the negative effects were cleared as she clicked to confirm leaving this world.

"Kotori..."

Kanroji Mitsuri blinked blankly, her gaze shifting between Rengoku Kyojuro and Itsuka Kotori with a puzzled look.

She had some contact with Rengoku Kyojuro, and therefore knew that he had a younger sister named Itsuka Kotori.

As if she had realized something, she covered her mouth and exclaimed, "Could it be...?"

Some of the Pillars also came to understand the relationship between the two, and they all looked at Kotori Itsuka with surprise and uncertainty.

The Balrog of Ratatosk is actually Kyojuro Rengoku's sister?!

This guy was hiding it way too well!

However, this is clearly not a good time to ask.

"Kotori, what happened?"

Rengoku Kyojuro hurriedly stepped forward and grabbed Itsuka Kotori's arm.

However, it only lasted for a fleeting moment.

As her body continued to become ethereal, Kotori Itsuka's body completely lost its physical form, turning into a faint, ethereal shadow.

The demon mask on his face fell to the ground, revealing a helpless expression.

"Brother, I lied."

Kotori Itsuka sighed and said helplessly, "I am indeed very strong, but Muzan is not weak either. Destroying him consumed all my power. Although I am not under Muzan's control, I will also disappear soon because I have exceeded my limit."

"how so......"

Upon hearing Kotori Itsuka's explanation, not only Kyojuro Rengoku, but everyone else also showed complicated expressions.

They had thought it would be a victory without sacrifice.

Even if someone were to sacrifice themselves, it's impossible for them to be the most powerful Flame Demon among them.

But now, Kotori Itsuka has become the only victim.

Ratatoskr and the members of the Demon Slayer Corps all wore expressions of sadness.

"There is no need to be sad. A great victory is something to be happy about, with one person's sacrifice."

Kotori Itsuka patted Kyojuro Rengoku on the shoulder, as if to encourage him.

But her body was so transparent that it was impossible to see, so all she could do was make a gesture of patting someone on the shoulder.

"I'm sorry for intruding into your life and leaving without permission."

Just before she completely disappeared, the savage, ferocious look on Kotori Itsuka's lips had already vanished.

Instead, there was the same innocent and sweet smile that Rengoku Kyojuro remembered.

"Brother, live well."

With her last words, her body transformed into particles of light and vanished completely from this world.

All that remained was the demon mask and a pair of white headbands.

"There's no need to apologize, my sister."

Gazing at the belongings left behind by his sister, Rengoku Kyojuro silently picked them up, closed his eyes, and murmured to himself.

"You will always be a part of the Purgatory family."

Opening her eyes, the girl found herself back in the familiar settlement space once again.

"call......"

She let out a deep breath, feeling fortunate that her plan had succeeded.

Fortunately, Muzan Kibutsuji did not escape.

Towards the end of the battle, Kotori Itsuka's spirit crystals began to affect her mind, almost causing her to lose herself in the fighting and forget that her primary goal was to kill Muzan Kibutsuji.

This gave him the opportunity to escape.

But the result was still good; two Pillar-level members stopped him, and in the end, Muzan Kibutsuji still died at her hands.

And the excuse she gave for leaving this world was beyond question in the eyes of others.

After all, only she knew that her true strength was enough to completely defeat Muzan Kibutsuji. Others only knew a portion of her fighting power and assumed that she and Muzan Kibutsuji were evenly matched.

He used all his strength to destroy the Demon King, but he also disappeared after the battle because he had exhausted his life force.

This was the most reasonable ending the girl could come up with.

After giving her mind a short rest, she looked at the system panel to check the rewards and rating she had received after passing through this world.

"The role-playing level is A? Hmm, that's about what I expected."
