Crossover Anime: Edit everything, join the chat group

Shinobu Kocho huddled in her room, her body trembling with fear and anger.

Just moments ago, the Nichirin Blade that hung on the wall, belonging to her older sister Kanae, emitted a mournful cry without warning. It was an extremely subtle yet sharp resonance capable of piercing the soul.

From that mournful cry, she "saw" a blurry and bloody illusion—a raging fire was being swallowed by endless darkness, and a man as dazzling as the sun, covered in blood, was slowly falling.

It's Mr. Purgatory!

This realization was like a cold, poisonous needle, piercing her heart. She didn't know why she had seen this, but the ominous premonition from the depths of her soul was so real, so intense, that it almost suffocated her.

Almost instinctively, she sent out a distress signal in the chat group.

[Butterfly Dance]: Gu Chuan-jun! Observer, I beg you! Please save Mr. Flame Pillar! I have a feeling he... he's about to die!

This almost heart-wrenching cry for help instantly froze the previously warm atmosphere of the group chat. Every word of the message seemed to carry a cold weight, pressing heavily on the hearts of every member who was watching.

【Alice】: Be patient, calm down, what exactly happened? Don't be afraid, tell me slowly, we (one) ball flag lost q seems to be walking skirt are all there.

[March 7th]: Mr. Rengoku is dying?! How could this be! Isn't he one of the strongest Pillars of the Demon Slayer Corps? Could it be that he encountered that final boss named Muzan?

[Jewel Magician]: Hey! What happened? Is it another Upper Moon demon? What's the situation? What abilities does the enemy have? Are you safe?

After spending these past few days together, everyone in the group has basically learned about what's happening in their respective worlds, and they are all terrified by the impending death of the Flame Pillar.

She stared intently at the screen, her knuckles turning white from the effort, placing all her hopes on the "Observer" D.

This mysterious and powerful man was the only ray of light she could think of that pierced through the despair of this world.

【bite--!!!】

Just then, a cold yet powerful system notification suddenly exploded in the minds of all members without warning!

[Warning: Strong negative emotional fluctuations detected in member Chomae; her world, Demon Slayer, has been declared an apocalyptic world!]

The core keywords for the world are: [hatred], [despair], [resistance]...

[World Mission: Together in the Apocalypse, now forcibly activated!]

【Quest Name: The End of the Thousand-Year Curse】

[Mission World Locked - The World Where [Butterfly Dance] Is Located!]

[Ultimate Mission Objective: To completely eradicate the source of calamity—the progenitor of demons, Muzan Kibutsuji!]

[Mission Description: This is a world cursed by "ghosts" for thousands of years. Please assist the "resistance" of this world to break these chains of despair and usher in true dawn.]

[Teleportation access will be available soon! Selected companions, please prepare!]

[Teleportation access will be available soon! Selected companions, please prepare!]

The cold system announcement, like a thunderclap, exploded in Gu Chuan's mind.

The atmosphere inside the student council room remained warm and welcoming.

Yukino is trying to freeze black tea into various cute animal shapes, while Fujiwara Chika pesters Eriri to teach her how to draw characters, exclaiming "Wow! So cute!" from time to time.

Gu Chuan still wore a calm smile, as if nothing had happened, but his deep eyes were focused on the virtual screen that only he could see.

The chat group was in an uproar because of this sudden mandatory task.

[March 7th]: Wow! The quest has been triggered! Who will I draw this time? I'm so nervous!

[Little Cat Thief]: I hope I get picked! I've been working really hard to save up points lately!

[Ice Queen]: Hmph, a choice of fate? Slaying the progenitor of demons... sounds like a good prey. System, choose me.

[Alicia]: Great, Shinobu! This way, the Flame Pillar will definitely be saved!

[System notification: Companions are being randomly selected... The pointer of fate will soon stop for you.]

The enormous virtual roulette wheel suddenly accelerated its rotation in Gu Chuan's vision, with countless Ds transforming into streaks of light that were too fast to capture.

Finally, with a cold yet domineering "ding," the roulette wheel slowly slowed down, and the pointer came to a steady stop on a "D" that shimmered with an intensely icy blue light.

【The Ice Queen!】

"—Hehe, hehehehe...hahahahahaha!"

On the cold throne of the Empire, Esdeath stared at the finalized name, momentarily stunned, then burst into a hearty and unrestrained laugh.

That laughter was filled with an undeniable desire to conquer and a powerful sense of self-confidence.

"Excellent! Very good! It seems even fate agrees that only I am qualified to stand beside the strong!"

She stood up, stuck out her tongue, and gently licked her scarlet lips. Her icy blue eyes gleamed with a bloodthirsty yet excited light.

"The progenitor of demons? I really hope he'll be more fun to play with than I imagined."

This result caused an uproar in the chat group.

[Gem Magician]: What?! It's this guy?!

[March 7th]: Wow! It's Esdeath! I feel... I feel that Muzan is going to be in big trouble...

[Alicia]: Oh dear~ This is truly... the worst yet most interesting development ever~ A sadistic queen is going to a world full of tragedy... Miss Shinobu, please pray for your good luck~

[Ice Queen]: ...Heh, an interesting little girl. I hope your magic isn't as weak as your words.

[Butterfly Dance]: Thank you everyone, thank you...

……

In the underground workshop of the clock tower, Rin Tohsaka looked at the result and was so angry that she almost crushed a ruby ​​in her hand.

"Damn it! Why did it have to be that violent woman?!"

She stomped her foot in frustration. The thought of Esdeath being able to travel to another world alone with Gu Chuan, while she could only wait here, filled her with an unprecedented sense of crisis and resentment.

Although she had spent a lot of points before, Rin has managed to accumulate 1300 points in the past few days by checking in and completing various small tasks in the group chat.

She glanced at the "huge sum" of 1300 points in her account, and then at the option in the system prompt that "pay 1000 points to obtain peer status".

Hmph, I'm not jealous!

I only... I'm just worried about leaving Gu Chuan and that dangerous woman alone together! Yes! That's it!

Rin found herself a perfect excuse.

1.5 She didn't hesitate at all and clicked on that option.

[System notification: "Gem Magician" has paid 1000 Inspiration Points and successfully qualified for this event!]

[Gem Magician]: All members, beware! Hmph, don't get me wrong, I don't want to go. It's just that the world of ninjas is full of curses and mysteries, and they need an expert like me to provide technical guidance. Ice Queen, don't you dare hold me back!

[Ice Queen]: ...Heh, an interesting little girl. I hope your magic isn't as weak as your words.

Inside the student council room, Gu Chuan looked at the heated conversation in the group chat and shook his head helplessly.

He stood up and said to the three girls who were playing around, "Excuse me, I need to go to the restroom."

This is a perfectly normal excuse that no one would care about.

“Oh, okay, Kawa-kun!” Fujiwara Chika replied without looking up.

Gu Chuan went into the restroom and closed the door.

[System notification: Companion has been locked.]

[Teleportation countdown: 10, 9, 8...]

A dazzling golden light, composed of countless data streams, began to emanate from Gu Chuan's body.

"Then, let's begin. (Yi [锍?医伞]2尔児)"

"...3, 2, 1."

[Transmission begins! 】

The light shone brightly, completely engulfing Gu Chuan's figure.

The next second, the light faded, and the restroom was empty.

It was as if he had never existed.

66. Akaza and Flame Pillar

……

Demon Slayer World.

"boom--!!!"

With a deafening roar, a huge crater was blasted into the ground next to the overturned Infinite Train.

Kyojuro Rengoku knelt on one knee, blood flowing from the wound on his forehead, blurring the vision in his left eye.

He gasped for breath, each breath causing excruciating pain as his broken ribs snapped. His Nichirin Blade leaned against the ground, supporting his body, which swayed precariously like a candle in the wind.

No… I must stand up! Purgatory roared inwardly. As a Pillar, my duty is to protect the weak! Behind me are three promising juniors! And those two hundred innocent civilians on the train! What will happen to them if I fall?!

Dear Mother, have I done a good job? Have I... fulfilled my responsibilities?

His chest and abdomen were covered with deep, penetrating wounds that revealed the bone, and the blood had long since stained his prized haori, which was decorated with flame patterns.

"Give up, Kyojuro."

Standing opposite him was a man covered in dark blue tattoos and with short, peach-pink hair.

He was shirtless, with a twisted yet admiring smile on his lips; it was none other than Upper Moon Three, Akaza.

"Your fighting spirit is already like a candle flickering in the wind, yet it still burns so brightly. It's truly admirable! Become a demon, Kyojuro! By becoming a demon, you can transcend the shackles of birth, aging, sickness, and death, and together with me, forever pursue the highest realm of martial arts!"

"I reject!"

Purgatory's voice was hoarse, yet still as loud as a bell, "Aging and death are precisely the beauty of humans, these short-lived creatures! It is because we age and die that we are so precious and so powerful! And you are nothing but a monster who cannot face your own weakness!"

I will burn my heart out to light up this darkness!

"Flame Breathing Secret Technique Ninth Form: Purgatory!"

He used his last ounce of strength, pouring all his life and will into this single strike! His entire being transformed into a burning, spiraling tornado of fire, charging towards Akaza with the force to incinerate everything!

"What a pity, Kyojuro!"

A hint of regret flashed in Yi 15's eyes, but it was quickly replaced by stronger excitement. "In that case, let me, with the utmost respect, utterly shatter your brilliant life!"

"Destruction and Annihilation!"

Both being supreme mysteries, these two ultimate forces collided with a deafening roar!

“No…don’t!!!”

In the distance, Tanjiro Kamado roared with all his might. He could smell the stench of death and decay rapidly intensifying around Mr. Rengoku. His heart felt as if it were being gripped tightly by an invisible hand, the pain suffocating him.

Why! Why is this happening! We already defeated Lower Moon One, so why has such a powerful demon appeared again! Our power... is completely useless! Are we... going to have to watch someone important die right before our eyes again?!

For the first time, Inosuke Hashibira, who was standing beside him, felt the emotion called "fear." His beast-like instincts were frantically telling him that the enemy in front of him was invincible.

"Mr. Purgatory—!!!"

At the center of the collision between flames and fighting spirit, a blinding light erupted. As the light dissipated, Rengoku Kyojuro's Nichirin Blade ultimately failed to sever Akaza's head; instead, it was pierced deeply through Akaza's chest by the latter's fist.

“It’s over,” Akaza said softly.

However, just as he was about to withdraw his arm and end the life of the Flame Pillar, a sudden change occurred!

The night sky seemed to have been torn open by an invisible hand.

A dazzling, magnificent portal, composed of countless golden data streams, unfolded without warning directly above the battlefield. Its sacred and solemn aura instantly plunged the entire battlefield into an eerie, deathly silence.

Akaza suddenly looked up, and his golden pupils, engraved with "Upper Moon Three," suddenly contracted!

What it is? !

He saw three figures slowly walk out of the radiant teleportation portal.

Leading the group was a young man with black hair and black eyes. He had a calm expression and indifferent gaze, as if the fierce battle before him was nothing more than a boring drama on the roadside.

To his left stood a tall, stunningly beautiful woman with long, icy blue hair. A bloodthirsty yet pleased smile played on her lips, and her icy blue eyes were filled with scrutiny and disdain for the powerful, like a queen surveying her territory.

To his right stood a petite blonde girl with twin ponytails. She crossed her arms, looking displeased and haughty, her deep blue eyes filled with obvious wariness and hostility, like an anxious wife who had come to spy on her husband.

An ordinary person?!

Kyojuro Rengoku's consciousness was beginning to fade, but the moment he saw the three of them, his instincts as a Pillar were instantly triggered. No… wait! Why are they here?! Run! There are Upper Moon demons here! Run!

He tried to shout, but only a hissing sound of blood and froth escaped his throat. A despair deeper than death welled up inside him—not only had he failed to protect his juniors, but now he was also implicated three innocent bystanders!
