A World Without Demons, a New Beginning

Moyu's body was enveloped in Azure energy, and like a shooting star against the current, he flew upwards along the vertical path he had opened with "Zi". The whistling wind was in his ears, and the muffled rumble of the collapsing Infinity Castle below gradually faded into the distance and became blurred. After an unknown amount of time, a glimmer of light finally appeared ahead.

"Whoosh..."

Moyu's figure soared into the sky from a huge, mirror-like pit in the ground, landing steadily on the ground beside it. The night breeze carried the fresh scent of grass and trees, replacing the nauseating stench of decay within the Infinity Castle. He looked around, his six-eyed senses quickly scanning the area; he was in an unfamiliar Mountain Forest, far from any human habitation.

Almost as soon as his feet touched the ground, that long-lost mechanical voice, which only he could hear, rang in his mind:

[Ding! Host has detected killing a target... Calculating...]

[120 common ghosts killed]

[Defeat Upper Rank Six - Kaigaku]

[Defeat Upper Rank Four: Nakime]

[Defeat Upper Rank Three, Akaza]

[Defeat Upper Rank Two- Doma]

[Defeat Upper Rank One, Kokushibo]

[Defeat the Demon King, Muzan Kibutsuji]

[Total Coins Earned: 205,100]

[Current remaining Coins: 240,000]

A series of numbers flashed by, Moyu remained calm, showing little emotion. Accumulating Coins was not his goal. However, the system notification continued:

[WARNING: The core plot objective of the current world, "Muzan Kibutsuji," has been completely destroyed... A major shift in the world line has occurred...]

[System upgrade initiation... Current progress: 1%...]

"Upgrade?" Moyu's heart stirred slightly, but he didn't delve into it. There were more important things to do right now.

With his six eyes fully activated, his perception spread rapidly in all directions like invisible ripples. The outlines of mountains, rivers, and towns flashed through his mind. Soon, he locked onto a direction where many familiar and powerful life auras converged. Among them were the energy fluctuations of Kagaya Ubuyashiki, which, though weak, were unusually stable at the moment, as well as the clear presence of Tanjiro, Nezuko, Shinobu Kocho, and others.

"Found it."

Without further delay, the space around Moyu slightly distorted, and the Azure light reappeared.

"Azure."

The next moment, his figure disappeared from the Mountain Forest, speeding towards the Demon Slayer Corps headquarters at a speed beyond human comprehension. In the night sky, only a fleeting pale blue trail remained.

Outside the Ubuyashiki, headquarters of the Demon Slayer Corps.

The sky was still dark, with only a sliver of light appearing in the east and the stars not yet completely hidden. But the open space outside the mansion gate was already filled with people.

All the Pillars— Kyojuro Rengoku, Giyu Tomioka, Tengen Uzui, Sanemi Shinazugawa, Obanai Iguro, Muichiro Tokito, Mitsuri Kanroji, and Shinobu Kocho —were present. Each of them wore the Demon Slayer Corps Gyomei Himejima, with their Nichirin Blades at their sides, their expressions solemn yet tinged with an indescribable anticipation and tension.

Tanjiro, Zenitsu Agatsuma, Inosuke Hashibira stood slightly forward. Tanjiro gripped the hilt of his Nichirin Blade tightly, his nose twitching slightly as if he were trying to decipher the air. Zenitsu's teeth chattered with tension, but he managed to stand firm. Inosuke, on the other hand, crossed his arms, his eyes wide open beneath his Boar's Head, darting restlessly left and right.

The three girls from the Butterfly Mansion, Kiyo, Sumi, and Aoi, along with Kanao Tsuyuri, stood quietly not far behind Shinobu Kocho. Kanao Tsuyuri tightly clutched the handmade bookmark that Tanjiro had given her earlier.

Amane Ubuyashiki supported Kagaya Ubuyashiki, standing at the forefront of the crowd. Surprisingly, the bandages that had bound Kagaya Ubuyashiki's face for many years had been removed, revealing a pale and thin face, yet exceptionally handsome and gentle. He was still blind, but his blind eyes now seemed to have a light in them. Even more astonishing was that his body, which had been corrupted by the curse and almost sentenced to death, although still weak, radiated an unprecedented vitality, as if withered trees had come back to life, and the shadow of the curse had been swept away!

The members of the stealth unit were scattered around, maintaining order, but their faces were also filled with excitement and disbelief.

All eyes were fixed on the clearing ahead, which appeared exceptionally silent in the pre-dawn darkness, as if waiting for something.

This unusual calm and anticipation stems from the dramatic changes that occurred not long ago.

At the very moment the Infinity Castle collapsed and Muzan was utterly Annihilation, all the demons connected to Muzan by blood felt Disintegration originating from their very source. Kagaya Ubuyashiki, as the head of a clan sharing the same bloodline as Muzan, felt it most clearly and profoundly. The curse that had plagued the Ubuyashiki Family for millennia, like a malignant tumor, melted away like snow under the sun. The pain that had tormented him suddenly lessened, and an unprecedented sense of ease swept through his body. He could almost see the darkness that had shrouded his family's fate being completely dispelled by an invisible hand.

Almost simultaneously, Tamayo, who was temporarily staying at the Butterfly Mansion and responsible for liaising with the Demon Slayer Corps, began to become transparent. Instead of panicking, she revealed a relieved and utterly serene smile. She left her final words to Yushiro, who was standing by her side in a state of panic:

"Yushiro... don't grieve. Muzan. My wish... has finally come true. These hundreds of years of suffering can finally end. It's me... I'm sorry to you and those innocent people... Please... live well for me... as a human being..."

After speaking, her figure transformed into specks of light and vanished completely into the air. She could have taken the Demon Transformation Medicine, but she chose to be freed from her painful past. Hundreds of years ago, after being deceived by Muzan and turned into a demon, the nightmare of killing her husband and child with her own hands in a state of loss of control, and the guilt of having to take lives despite her best efforts to restrain herself, had already tormented her heart beyond repair. Muzan's death was a release for her, a redemption.

Yushiro, a demon directly transformed from Tamayo, did not disappear with Muzan. He knelt on the ground, tears streaming down his face, but finally, trembling, he picked up the pale golden bottle of Demon Transformation Medicine left by Tamayo and drank it down. At this moment, he was in the Butterfly Mansion's room, enduring the transformation process brought about by the medicine. His body was sometimes cold and sometimes burning hot, his consciousness was blurred, but he had only one thought in his mind: to fulfill Tamayo's last wish and live on as a human.

It was these strange phenomena, occurring in different places yet closely connected, that made the people gathered here realize that the shadow that had shrouded the world for a thousand years, the demon Demon King named Muzan Kibutsuji, had truly... vanished!

The world has ushered in a dawn without ghosts.

But at this moment, they still had one thing on their minds: Moyu, the Eye Hashira who had single-handedly stormed into the Infinity Castle and faced all the Upper Rank, Muzan.

How is he...?

In the stillness before dawn, a streak of Azure light, like a comet streaking across the night sky, streaked swiftly from the distant horizon and silently landed on the open ground in front of everyone. As the light faded, Moyu's figure was revealed.

He was still wearing that dark blue Demon Slayer Corps, a white Haori, snow-white hair, and... a black blindfold. His breathing was steady, and apart from a few inconspicuous specks of dust on the hem of his Haori, he looked almost exactly the same as when he left.

"Moyu!"

"Senior Moyu!"

"Eye Hashira!"

"Mr. Moyu!"

In an instant, various greetings rang out, filled with surprise, excitement, and relief.

Tanjiro was the first to rush forward, tears streaming down his face uncontrollably. "Senpai! I'm so Muzan you're alright! Nezuko..." He was so excited that he was almost incoherent.

Moyu tilted his head slightly, looked at Tanjiro, then at everyone else, and nodded gently. "Yes, it was resolved smoothly."

Those few simple words were like a final verdict, completely dispelling the last trace of gloom in everyone's hearts.

"Great! Waaaaah... I knew Moyu- senpai was the strongest! I don't have to worry about being killed by demons anymore!! I want to marry Nezuko!" Zenitsu yelled, wiping away his tears.

"Hmph! Looks like you've got some skills after all!" Inosuke thumped his chest loudly, his tone still impetuous, but everyone could hear the joy in his voice.

Kyojuro Rengoku strode forward, his voice booming. "Young man Moyu! Well done! This achievement is enough to shine in the thousand-year history of the Demon Slayer Corps!"

With his hands clasped together, tears streaming down his face, Gyomei Himejima said, "Namo Amitabha... Thank you Moyu... for ending this thousand-year curse..."

Sanemi Shinazugawa scoffed, but a smirk involuntarily crept onto his lips. "Finally... that bastard is finally dead."

Tengen Uzui sized up Moyu: "A magnificent victory! As expected of our Eye Hashira!"

Giyu Tomioka nodded silently. Mitsuri Kanroji was already sobbing uncontrollably, wiping her tears while smiling and saying, "That's great... that's really great..."

Obanai Iguro stood beside Mitsuri, looked at Moyu, and nodded slightly.

Muichiro Tokito's empty gaze seemed to focus a little more as he silently looked at Moyu.

Shinobu Kocho up to Moyu, her violet eyes gazing deeply at him. A genuine, gentle, and radiant smile graced her face, though tears glistened in her eyes. "Welcome back, Moyu- kun."

Supported by Amane, Kagaya Ubuyashiki took two steps forward and bowed deeply and solemnly in the direction of Moyu: "Moyu... On behalf of the Ubuyashiki Clan, on behalf of all the fallen members of the Demon Slayer Corps, on behalf of all those persecuted by demons... thank you. We will never forget this kindness."

Moyu stepped forward and supported Kagaya Ubuyashiki: "My Oyakata-sama, there's no need for this. This is something I promised." His six eyes could clearly see that the curse in Kagaya Ubuyashiki's body had been completely removed, but his body, tormented by illness for many years, was still very weak. He reached out his hand, his palm glowing with a soft white light, and gently pressed it on Kagaya Ubuyashiki's back.

Warm, pure, positive energy flowed slowly in, nourishing Ubuyashiki's battered body. Kagaya Ubuyashiki felt a warm current sweep over his entire body, and the long-lost sense of strength gradually returned. Although he couldn't recover his health immediately, the feeling of being completely exhausted was greatly relieved.

"Thank you..." Kagaya Ubuyashiki's voice choked with emotion.

Moyu looked at Nezuko and could clearly see that the effects of the Demon Transformation Medicine were still working in her body, but slowly, and some deep memory blocks had not yet been fully activated. Yushiro's situation was different, but the transformation process was also full of pain and stagnation.

Moyu didn't say much, but stretched out his hands, his palms hovering in front of Nezuko and Yushiro's foreheads respectively.

The warm, soft white light shone again, more concentrated and containing a purer life force and guiding power than when it was used to treat Ubuyashiki. This was an advanced application of the reversal technique.

The white light seeped into Nezuko and Yushiro's bodies. Nezuko hummed softly, closed her eyes, and a comfortable expression appeared on her face. In her mind, long-forgotten images surged like a tide: a warm home, a busy mother, mischievous Delia, quiet younger brothers, a strict yet kind father... and that bloody night, the tragic sight of her mother and siblings lying in pools of blood... Then there was the hardship of her brother carrying her around seeking help, Urokodaki's acceptance of her, her first encounter with Moyu on Mount Sagiri, Tanjiro's diligent training, and the care she received from everyone at the Butterfly Mansion... Countless fragments of memories were sorted out, integrated, and became clear again.

On the other side, Yushiro groaned and knelt on the ground, his body trembling violently. The rejection reaction and transformation pain caused by the Demon Transformation Medicine were quickly alleviated under the guidance of the reversal technique. Human life force accelerated the replacement of the remaining demon cells, and his complexion became rosy at a visible speed.

A moment later, Moyu withdrew his hand.

Nezuko slowly opened her eyes. Her pink eyes held less of their initial confusion and more of a clear and gentle quality born from experience. She looked at Tanjiro, who was weeping, then at everyone around her, and finally her gaze settled on Moyu. A familiar yet new smile appeared on her lips, while tears streamed down her face.

"Brother... everyone... I... I'm back." Her voice was still soft, yet it carried complete emotion and memory.

"Nezuko!" Tanjiro hugged his sister tightly again, this time with the overwhelming joy of having her back.

"Ne... zu... ko!" Zenitsu happily turned into a wave shape and pressed himself against her.

Yushiro struggled to his feet, still weak, but his eyes had hardened. He bowed deeply to Moyu and to Kagaya Ubuyashiki: "Thank you... I will... live well for Lady Tamayo's sake."

At this moment, Moyu's gaze turned to Muichiro Tokito in his eyes. This exceptionally talented young Pillar had lost his memories before the age of eleven.

"Tokito," Moyu said.

Muichiro raised his head and looked at him blankly.

Moyu walked up to him and, following the same method, placed his palm in front of his forehead. White light seeped in, and this time, Moyu carefully guided the energy, stimulating the memory areas deep within Muichiro's brain that had been sealed off due to extreme stimulation.

A house engulfed in flames... a demon wielding a sharp blade... the severed arm of his Yuichiro... his own raging fury... pinning the demon to the field with wood and farm tools... his brother's dying words. "Muichiro's 'Mu' is infinite 'Mu'... Go and help others..."

The floodgates of memory were opened, and countless forgotten images rushed into his mind. Muichiro's body trembled violently, and tears welled up silently. He opened his mouth, but no sound came out, finally turning into a suppressed sob. He remembered everything.

Gyomei Himejima forward and gently patted Muichiro's shoulder. "Namo Amitabha... It's good to be back."

Finally, Moyu looked at Kagaya Ubuyashiki. "My Master, although your body is not cursed, it still needs recuperation due to years of wear and tear."

Kagaya Ubuyashiki smiled and shook his head, "To be able to witness this day is already the greatest blessing from heaven. There's no need to waste any more time on me..."

Moyu didn't say much, and once again cast the Reversal Technique. The pure life energy, like the gentlest spring water, Kagaya Ubuyashiki's body, which had been weakened by years of illness, and repaired those deep-seated damages. Kagaya Ubuyashiki could clearly feel a long-lost vitality reviving within his body.

By the time all this was done, it was already broad daylight. Golden sunlight bathed the earth, illuminating everyone's tear-stained yet hopeful smiling faces.

Kagaya Ubuyashiki looked at his team members who had endured countless hardships and finally achieved victory, and said in a gentle yet firm voice, "I hereby declare that, effective from this day forward, the Demon Slayer Corps... is disbanded."

There was no disappointment as expected, but rather a sense of relief and tranquility. The battle that had lasted for a thousand years had finally ended, and this sharp blade, which had been tempered by countless lives, could finally be returned to its sheath.

"However," Kagaya Ubuyashiki changed the subject, a smile spreading across his face, "Although the Demon Slayer Corps has disbanded, the bonds between us will never break. This will always be everyone's home. In the future, perhaps we can help those in need in another way."

Everyone nodded in agreement and began excitedly discussing their future plans. Kyojuro Rengoku, with the loudest voice, declared he wanted to open a dojo and teach Flame Breathing; Mitsuri Kanroji blushed and said she wanted to open a confectionery shop; Obanai Iguro said he wanted to do it with Mitsuri; Tengen Uzui declared he would continue his magnificent adventures with his three wives; even Sanemi Shinazugawa muttered that he needed to find some peace and quiet...

Tanjiro, holding Nezuko, discussed with Zenitsu Inosuke about visiting Urokodaki- sensei first, then going back to their hometown to rebuild the Kamado family. Kanao Tsuyuri stood not far away, quietly watching Tanjiro with a faint smile on her lips.

Shinobu Kocho walked up to Moyu, her purple eyes gleaming in the sunlight. "Moyu- kun, what are your plans for the future?"

Moyu removed the black cloth covering his eyes and looked up at the azure sky. In his six-eyed perception, the world was clearer and calmer than ever before. He shook his head slightly. "Haven't decided yet. Perhaps I'll travel around."

Shinobu smiled gently. "I see... Well then, have a safe journey." Her gaze swept over Nezuko, who was being affectionate with her brother, and the vibrant garden of the Butterfly Mansion, and she added, "However, the Butterfly Mansion will always welcome you back."

Moyu nodded.

The sun shines brightly, and a gentle breeze blows. The darkness that has lasted for millennia has finally dissipated, and the ordinary yet authentic new life that belongs to everyone is slowly beginning at this moment. The air is filled with the last fragrance of Wisteria, and... the scent of a hopeful future.

(That's all, going to play games now ღ( ´･ᴗ･` ) Sending love)
