I created the Holy Grail War, shocking the world

[It seems to be useless. ]

【suddenly.】

[“Gem Sword!”]

Luo Shu's eyes lit up as he thought of the design drawings left by his ancestors.

[That is the magic gift set that Jewel Master possesses. It is the pinnacle of magic gift sets with the second magic as its limited function. It can share and use the great source magic power of infinite parallel worlds.]

If I could obtain that, I would have a chance to avoid a fate where I and Kaguya would perish together.

[I once tried to replicate the jewel sword using the blueprint.]

But the results were far from ideal.

【But he has Yukino now. 】

[With her miraculous "projection magic" proficiency, it is possible to replicate the jewel sword.]

Reality, people whispered.

"Gem Sword, what kind of artifact is this?!"

"I don't know duck."

"Being able to draw upon the great source of magic from infinite parallel worlds, sounds..."

"About infinite mana bars?"

"Take Black Saber as a reference. She has an infinite magic cannon and even defeated Uncle B."

"Hiss, I have an idea!"

"Bao Shi Weng is simply full of treasures."

"As expected of a magician who even appears in Land of Fullmetal."

"So... Luo Shu was drained dry by Xue No?"

(bfch) "Le, you old pervert, why are you paying attention to this? Isn't the artifact more interesting?"

"I want it to be sexy!"

"If Yukino can project the jewel sword, then the chances of winning are very high, right?"

……

“Failed.”

A somewhat lonely voice echoed across the sky.

In an instant, people's discussions stopped abruptly and everyone looked at each other in astonishment.

[…It’s still difficult to imagine based on just the blueprints.]

Luo Shu rested his thumb on his chin, thinking, "After all, even in the inheritance of the Shigong lineage, it is considered a secret treasure among secret treasures. But fighting against Kaguya, without it, I probably won't be able to do it."

"Sorry." Beside him, Yukinoshita Yukino looked apologetic.

【“No…it’s nothing. There is another way.”】

Luo Shu smiled gently and caressed Yukino's cheek. "Using the memories of Einzbern and the memories flowing through the spiritual veins of this land, I can project the jewel sword."

"With Yukino's intelligence, she'll definitely be able to copy the jewel sword once she sees it with her own eyes."

【"Um?"】

Yukino tilted her head.

……

[After a long time, under Luo Shu's guidance, Xue Noi and the pink-haired android of Aibao arrived at a secret underground chamber with a long history. The surrounding candlesticks were lit with faint flames, and the ground was engraved with mysterious magic circles.]

[In a dusty box, Luo Shu pulled out the mercury sword from the red cloth and handed it over.]

[“This is made to imitate a jewel sword. It can be used to assist you in projection.”]

【"Um."】

Yukino nodded and took it calmly.

[Luo Shu had already told her the detailed process, so she just needed to put aside all distractions and do it.]

"Ms. Yukino, it's about to begin."

[The pink-haired maid was a little solemn and placed her hand on Yukino's shoulder.]

[As Yukino closed her eyes, the mysterious flow of magical energy continued to gather in her mind.]

【The vision gradually turns black.】

……

The exciting BGM background music exudes a sense of simplicity and heaviness.

The waves hit the beach, and the sand is particularly beautiful under the sunlight, making people unable to help but immerse themselves in the picture.

Ancient memories, the past, the figures of three magicians... finally appeared before everyone's eyes.

That was five hundred years ago.

A touching story.

This story tells the story of the ancestors of the Matou, Einzbern, and Shinomiya families. Two men and one woman went through countless hardships in pursuit of a common great ideal, and created the Holy Grail in the bunker under the witness of the jewel Ongishua Zelrich Schubin-aoug.

The image of the Gem Master appeared in the eyes of people from all over the world for the first time.

Looking at the white-haired old Deng standing high in the bunker, wearing a maroon cloak and with a calm face.

Many people were in awe.

This is exactly what I imagined a serious and wise elder to be like.

Yukinoshita Yukino was also staring at him seriously, or more precisely, at the sword hidden in his clothes on his chest.

【——『Jewel Sword (Zelretch)』! 】

"I believe in your ideals. To reach the source... the Shinomiyas, Einzbern, and Makiri, the three families will join forces to pave the way!"

[The Jewel Master looked at the three of them calmly, "Tell me what you can offer."]

[“The Shinomiya family provided the sacred ground for the Holy Grail.”]

A young man with long, flowing hair stepped forward, his eyes determined, revealing the passion unique to warriors.

[“The Machiri family provides the Command Seals to bind the Servant as a sacrifice.”]

A young man with blue hair resembling seaweed walked up, calm and light-hearted, yet his tone was powerful and resonant.

[That determination and persistence seems to be no less than that of Yukino, who wants to be a partner of justice. ]

"The heroic spirits are sacrifices."

In Beika Town, Inspector Megure frowned and chewed on this extremely terrifying information.

So... the Holy Grail actually made a false promise to Valhalla, deceiving these heroic spirits and using their souls or something else as the energy to fulfill their wishes, is that right?

……

[“The Einzbern family provided a magic circle to reach the third level of magic.”]

[Like a saint, a woman in pure white clothing and white hair stepped forward.]

[“Okay… I, Kishua Zelrich Schubin-Ogu, will witness and preside over this.”]

[Baoshi Weng's expression became more serious as he stood at the front of the stage, his eyes sharper than an eagle's.]

Immediately, the white-haired woman walked to the dark and deep stone platform and lay down with a calm expression. With a loud roar, as if a crane were continuously pressing down, the huge stone pillar suddenly fell.

[Looking at the huge object falling down, the white-haired woman smiled, as if she had fulfilled a long-cherished wish.]

【This is exactly what a sacrifice should end like.】

[“Bang!”]

[Amidst the blue-haired, seaweed-haired youth's melancholy, a crisp, crushing sound erupted.]

[On the stone platform, dripping blood slid down and merged into the magic circle underground.]

[Countless bright orange lights rise within the magical patterns, shocking and grand!]

[The Gem Master remained calm, pulling out a sword blade adorned with a multi-faceted gem, as beautiful as a rainbow, and gently tapped it against the mysterious stone pillar.]

【"call……"】

[Instantly, Yukino's pupils shrank sharply, and her breathing couldn't help but accelerate.]

[The origin of the Sword, which was sealed by the Holy Shroud and delayed its awakening, is awakening.]

[I saw it...]

【That sword.】

Wow!

Flickering white light suddenly filled the sky.

……

[The next day, Luo Shu quietly put away the jeweled sword and placed it in the pocket behind him.]

[In the kitchen, Yukinoshita Yukino, wearing an apron like a cook, smiled gently and came out with a steaming bowl of nourishing soup.]

The atmosphere was surprisingly cheerful and peaceful.

[It seems that he has obtained a secret weapon to deal with Kaguya. 】

[Although it is a poorly projected product.]

[It can only borrow the power of the parallel world itself, not the great source magic power of the entire parallel world...]

【But... that's enough! 】

【after.】

[As if to make up for childhood regrets, two figures shuttled through the city ruins.]

[Ride the carousel in the park, float in the river, swim in the crater where groundwater is generated...]

[Until dusk, sitting on the leaning building, the two of them quietly watched the sunset.]

【suddenly.】

[“Boom…!!”]

[The air exploded over a dozen kilometers, and the ground sank.]

The mountains surrounding Yuanzang Mountain gradually sank, forming a deep abyss.

[An extremely terrifying aura spread, carrying a gloomy smell.]

Before anyone could react, a pagoda made of seemingly endless dark branches slowly rose up, seemingly embodying the murderous intent, evil thoughts, and greed of the entire pan-human history... A thick shadow enveloped everything.

[It seems that its existence is exposing the sins committed by primates from ancient times to the present.]

[Black as jade, textured like blood, it flooded toward the moon like a tide.]

【Then, insert it into the sky backwards...! 】

Damn it? !

The next moment, people gasped in shock.

[The clouds were pierced, creating a hole dozens of kilometers wide!]

[It was as if half the sky was torn apart, and countless brilliant stars fell, illuminating the entire Fuyuki City with a dazzling light, which was extremely shocking.]

[“That is…”]

【Luo Shu's eyes were solemn.】

[Look at the holy, round white sphere at the center of the pagoda.]

[It is the true form of the Fuyuki Holy Grail! ]

[As expected…]

【Kaguya.】
