Crossover Anime: Edit everything, join the chat group

At the same time, another memory quietly surfaced. Ten years ago, at the end of that war, he watched the Knight King, who was about to disappear because she had lost her home, use his power called "Editor" to forcibly modify the laws of the world, anchor her to a physical body, and allow her to break free from the shackles of the Throne of Heroes and truly remain in the present world.

Meanwhile, in Fuyuki Church.

Kirei Kotomine stood before the stained-glass window, overlooking the silent city, but his thoughts drifted back to ten years ago.

That brutal Holy Grail War ended in a bizarre way that no one had anticipated. The Greater Grail mysteriously shattered, and its contents vanished without a trace. Even more incomprehensible to him was that Sab, who should have disappeared with the war, had miraculously survived in a perfect physical form.

He remembered clearly that a mysterious man had appeared beside Sab. That man was neither a Master nor a Heroic Spirit, yet he possessed an unfathomable aura that even the King of Heroes beside him found troublesome.

For ten years, this mystery has been troubling him.

Just moments ago, the immense, incredibly pure magical power surging from the depths of the earth, and the Command Seals reappearing on the back of his hand, were both telling him—

That man is back.

A more chaotic and interesting war is about to begin.

In the shadows behind him, King Gilgamesh, holding a wine glass, smiled with amusement: "Kirei, it seems the farce that can amuse even me is about to begin."

The basement of the Matou family's old house.

Gu Chuan calmly issued his first command as "Master" to the three girls beside him—his daughter Sakura, his maid Mengmeng, and the Knight King Artoria.

"—The war has begun."

He calmly set up the chess game.

"Our primary task is not fighting, but establishing a base. From today onwards, this will be our headquarters. Sakura, you and Momo will be in charge of the workshop's daily operations."

“Yes, Daddy 0.9.” Sakura nodded obediently.

His gaze then turned to the chat group interface, and he spoke to Rin on the other end.

"Rin, go back to the Tohsaka family first and act as a normal Master. Try to gather as much information as possible about all the other Masts and Sants."

"As for me, I will stay here and observe the situation."

As soon as Gu Chuan gave the order, all parties immediately began to take action.

At this moment, the entire city of Fuyuki transformed into a giant chessboard. As legendary heroes answered the call from various places and gathered here, the curtain of the Fifth Holy Grail War was officially raised in an unprecedented, chaotic, and unpredictable manner.

126 Yesterday's Dreams and Today's Battle

In Rin's room on the second floor of the Tohsaka family mansion.

The girl on the bed suddenly opened her eyes, breathing heavily. Sunlight streamed through the gaps in the curtains, casting dappled shadows on the floor—familiar and warm.

"...Was it a dream?"

Rin looked at her familiar yet unfamiliar body, now that she had grown into a young girl. In her mind, the experience of going back to the past, fighting alongside Gu Chuan, and ultimately saving her sister was like a dream, yet incredibly clear, imprinted deep in her soul.

She instinctively rushed out of the room, only to find that the room next door, which should have belonged to Sakura, was already empty.

She knew this was not a dream.

Sakura has a new life that is happier than staying with the Tohsaka family.

"That's... good."

Rin clenched her fists, her ruby-like eyes now devoid of any confusion. Now that her greatest wish had been fulfilled, she could act without restraint, for herself and for the glory of the Tohsaka family, to seize the final victory in this Holy Grail War!

22 The first thing she did was to channel her consciousness into that omnipotent chat group.

[The Gem Magician]: Everyone! I'm back!

[March 7th]: Rin?! Where did you go? You suddenly went silent!

[Jewel Magician]: (With a sigh of relief) It's a long story... I think I just... went back ten years and met Sakura when she was little. Then, with the help of Mr. Observer, I successfully... rescued her from that hell!

Rin's words were like a depth charge dropped into a calm lake, instantly causing the entire group chat to boil over!

[Alicia]: Oh my~ Going back to the past and changing fate? This is truly a miracle that even the gods find difficult to achieve.

[Little Cat Thief]: Really?! So, your sister's tragic fate has been completely rewritten?!

[Gem Magician]: Hmm! Although the process felt like a dream, it must be real!

[March 7th]: Wow! Brother Chuan is so handsome! Can he even manipulate time?!

Just as everyone was marveling at Gu Chuan's power, which could be described as "creator god", Rin dropped an even more bombshell.

[Gem Magician]: But... the mission doesn't seem to be over yet.

[Jewel Magician]: Just now, a Command Seal appeared on the back of my hand. The system notified me that the Fifth Holy Grail War has... begun.

[Everyone]: ? ? ?

【The Ice Queen】: The Holy Grail War? What is that? A new apocalypse?

[Observer]: That's one way to understand it. But Rin, your memories seem to have changed as well?

Gu Chuan, who had been lurking on the screen, finally chimed in.

[Gem Magician]: Huh? Why do you say that!

[Observer]: Because it was you who requested to go back to your childhood to change Sakura's state, but now you're using the word "seems".

[Jewel Magician]: Whoa, I remember now! This is probably due to the effects of spacetime distortion? Fortunately, although the memories from the two timelines are somewhat jumbled, your words have given me a point of reference. Phew, it's so good that Sakura is alright. But, does Sakura call you "Dad" now?

[Observer]: Yes.

[Gem Magician]: You bastard!!!

[The Ice Queen]: ?

【Alicia】: ?

[March 7th]: ? ? ? ?

【Butterfly Dance】：？？？？？？？？？？？？？？

【Sword Dao Shura】: ? ? ? ? ? ? ? ? ? ? ? ? What's with calling me daddy?!

[Observer]: A bloody battle revolves around the "omnipotent wish-granting machine," where only one of the seven can survive. It seems our act of purifying the Holy Grail was like injecting excessive energy into a giant signal tower, prematurely detonating it.

Gu Chuan's seemingly casual yet incredibly informative explanation left everyone speechless.

Why are you avoiding the important points?!

After school, in Fuyuki City.

Following the unusually active magical energy fluctuations, Rin tracked it all the way to a Japanese-style mansion. She could clearly sense that two powerful "Servant" auras were clashing inside.

She quietly scaled the wall, and what came into view was a servant dressed in a blue bodysuit and holding a red magic spear, who was mockingly cornering an ordinary-looking, orange-haired boy.

It's Lanc! Cú Chulainn!

And that boy... Rin recognized him; he was her junior from the same school, Emiya Shirou.

"Looks like he's just another poor soul caught up in the war."

Just as Rin was preparing to find an opportunity to intervene and, incidentally, test Lanc's strength—

Backed into a corner, Shirou Emiya, in a clumsy dodge, was kicked away by Lanc and crashed straight into the dilapidated warehouse in the yard!

"That's enough, kid."

Lanc raised the demonic spear in his hand, its crimson tip gathering deadly causal magic, and aimed it at the figure lying motionless on the warehouse.

"—The Piercing Thorn Spear (GeBolg)!"

Death is at hand!

At this moment, Shirou Emiya's pure, almost twisted, will to live and ideals of "not wanting to die" and "wanting to save everyone" resonated miraculously with the summoning circle beneath his feet, which he had used as a repair shop but had unintentionally been marked countless times!

However, since Sab in this timeline had already been intercepted by Gu Chuan, the Holy Grail System, after detecting this strong summoning request and the spacetime paradox, chose a special being that best suited Emiya Shirou's desire for "salvation" as its response in order to correct the causal relationship!

Buzz—! ! ! !

A dazzling, holy golden light, bright enough to illuminate the entire night sky, suddenly shot into the sky from that dilapidated warehouse!

The immense and sacred magical power even caused Lanc, who was about to deliver the fatal blow, to instinctively stop his Noble Phantasm and reveal an expression of astonishment.

The light dissipated.

A stunningly beautiful girl with long blonde hair, dressed in silver armor and holding a holy banner emblazoned with dragon patterns, stood solemnly before Shirou Emiya, like a saint descended to earth.

She turned around, looked at the disheveled boy before her, whose eyes shone with pure light, and asked in a clear and loving voice:

"—So, are you my Master?"

Rank: Rul, Judge.

The saint, Joan of Arc, answered the call.

The Chess Game of 127 Observers

The Matou family's old residence, once filled with sin and filth, has now been transformed by Gu Chuan into a temporary, fully functional combat command center.

A giant monitoring water mirror made of magic is suspended in mid-air, clearly and in real-time "live-streaming" everything that is happening in the courtyard of the Emiya residence in the distance.

"It's Cú Chulainn... the Son of Light from the legends of Ulster."

Artoria looked at the figure holding the red magic spear in the water mirror and recognized its true form at a glance. But when her gaze fell on the girl who emerged from the golden light and held the holy banner, her usually calm, lake-like emerald eyes revealed obvious and extreme surprise.

"But... Joan of Arc, the saint of Orleans? Why would she be summoned as a participant with the rank of Rul? This... this doesn't conform to the rules of the Holy War!"

"Rules are meant to be broken."

Gu Chuan remained calm, as if the abnormal situation before him, which was enough to overturn the foundation of the Holy Grail War, was just a trivial ripple caused by his own hand.

"You could say it's a minor side effect of our new contract," he explained calmly. "Because of Sab in this worldline..."

"You've already claimed that class. In response to the boy's overwhelming desire to save everyone, the Holy Grail has made an exception and summoned a special Judge who best embodies the concept of a savior."

Hearing this explanation, Artoria was even more shocked. To tamper with the Holy Grail's underlying rules and forcibly summon a Rul beyond the norm… just how terrifyingly high was the power and status of her new Mast?

"Don't get distracted, watch carefully." Gu Chuan's voice pulled her back to reality. "This is a rare and excellent opportunity to observe top-tier heroic spirits in battle up close."

Pointing to Lanc in the water mirror, he began to give his loyal knight king a live lesson, acting as a "mentor".

"Cú Chulainn's spearmanship is expansive and seemingly wild, yet every strike is precisely aimed at the target. Moreover, he is not merely a spearman."

As he explained, the water mirror's view switched, clearly magnifying the details of Lanc setting up traps on the ground with runes while moving at high speed.

"His Noble Phantasm, the Piercing Thorn Spear, is a demonic spear that reverses cause and effect. Once its true name is released, it will ensure that the heart is pierced before the spear is even thrust out, making it extremely difficult to defend against."

Meanwhile, the chat group was already buzzing with excitement thanks to the "live stream" footage shared by Gu Chuan.

[Ice Queen]: Oh? I really like this spearman's fighting style. It's full of wild beauty, enjoying the thrill of cornering his prey. A true warrior.

[Nightmare]: Ara ara~ The Judge? Possessing two Command Seals on all Servants... It's quite a convenient, yet quite troublesome, special ability.

[Jewel Magician]: (gritting his teeth) Emiya-kun, you idiot! How could you summon such a troublesome guy!

Just as everyone was discussing the matter heatedly, the battle at the Emiya residence had entered a critical stage.

Seeing Shirou Emiya about to be killed by Lanc's bullet, Rin could no longer stand idly by. She leaped from her hiding place, several magical gems shimmering with dazzling light already clutched between her fingers, ready to engage Lanc in all-out war!

However, just as she was about to make her move—

"That's it."

Gu Chuan, at the Matou Residence, looked at the scene in the water mirror and murmured to himself.

He didn't even get up; his golden eyes, which shone with divine radiance, narrowed slightly.

The power of the [Dominator] was activated silently.

"—I command, the air in front of you, at this moment, freezes."

In the courtyard of the Emiya residence, Lanc, who was preparing to throw his demonic spear with deadly force, suddenly froze!

He clearly felt that the space in front of him seemed to become as viscous as a quagmire in an instant! An invisible, incomprehensible, and enormous air pressure suddenly acted on the tip of his spear!

This resistance was so small and so fleeting that ordinary followers could not even detect it.

But for a hero of Cú Chulainn's caliber, that 0.01 second of stagnation is enough to be fatal!

His supposedly flawless, causally-reversing, fatal strike was derailed by this tiny, almost negligible mistake, its trajectory shifting in a way that was imperceptible to the naked eye!

Pfft——!

The crimson demonic spear still pierced through Shirou Emiya's body.
