Opening the Second Dimension in the FGO Way

Her own shield blocked Artoria's Noble Phantasm release?

"Nice work, kid! You bought me some time!"

Just then, Cú Chulainn suddenly stepped forward, a slight smirk on his face, his staff pointing directly at Artoria.

"Burn to ashes, wooden giant – Wicker Man!"

Chapter 10: Sibling Rivalry

Koizumi's mind wasn't on Mash at all; it was preoccupied with the battle between the mistress and her sister.

For some reason, Koizumi felt a strange sensation when he looked at this so-called Flandre.

It was as if she was different from the one he knew. What was going on?

Wait! That's not right. I don't even know this Flandre. Why would I say she's different from the one I know?

Leaving Koizumi aside for now, the scene shifts to the battle between Remilia and Flandre.

Remilia's sister, Flandre, wore a twisted, broken smile, her magical power immense.

"This isn't right... The Flandre I know isn't this crazy, and her rampages aren't this extreme."

The Eyes of Destruction on the other Flandre's body had basically spread all over. Flandre could at least suppress it; even touching her wouldn't instantly kill you. Hong Meiling, the gatekeeper, played with Flandre all the time, and nothing ever happened.

But the Flandre before her had nothing but a desire for destruction in her eyes. The destructive energy radiating from her body was almost visible. If she touched her, she'd probably explode instantly.

That's what Remilia thought, so... who is this Flandre in front of me?

Is it possible that Yukari was telling the truth? Remilia bit her lip, her eyes flashing with intense killing intent.

Regardless, the person before her was still her sister, Flandre Scarlet. Even if she was different from the Flandre she knew, her name was the same, and there was no doubt they were related by blood.

"So that's how it is... So-called fate is just toying with us!"

With another fierce shout, Remilia unleashed an exceptionally powerful aura. Pink magic power swirled around her body, and a pair of huge wings made of magic sprouted from her back. At this moment, she was exactly as she had introduced herself – Queen of the Night!

"You will submit to me, fate! I am the devil who controls destiny!"

Remilia brandished Gungnir in her hand and charged towards Flandre, attacking without mercy.

As Flandre's sister, she knew Flandre's strength well. If she didn't go all out, she would fall.

Moreover, the Flandre before her was clearly stronger than the Flandre she remembered, so she couldn't hold back even more.

"Hehehe... Sister... Let's play together with Flandre... and then—"

"—Let's become one with Flandre!"

Flandre's last words startled Remilia slightly, but the next moment, immense magical power erupted from Flandre's body, and an extremely familiar magical aura entered Remilia's senses.

The intense shockwave sent Remilia flying, but fortunately, Remilia reacted quickly and regained her balance.

"Flandre... what did you just... say?" Remilia stared at Flandre in a daze.

Flandre tilted her head slightly, a hint of confusion flashing in her eyes, which were filled with a desire for destruction.

"Eh? Sister doesn't want to become one with Flandre? You were so willing to become one with Flandre before? Besides, sister's blood splattered all over Flandre, it was very tasty!"

Flandre's words made Remilia feel a chill run down her spine. She could almost see the scene Flandre was describing.

Impossible... This is impossible... How could Flandre have done something like that?

Even if she's not the Flandre I know, at least, Flandre wouldn't do that...

But... I see, am I just deceiving myself? That's right.

Flandre is right. If Flandre's desire for destruction has really reached this point, I might really...

Remilia took a deep breath, her gaze fixed on Flandre, and her face returned to its previous arrogance.

"Flandre, bad children must be punished, so stay there and let me punish you properly!"

As she spoke, Remilia seemed to transform into a pink lance, heading towards Flandre without mercy, because she couldn't afford to show any mercy.

Flandre pouted, her face full of dissatisfaction. Although she looked quite adorable, considering Flandre's current destructive power, probably no one would dare to approach this little girl.

"Sister should obediently become one with Flandre. Since sister doesn't want to, that means sister doesn't love Flandre anymore, so—destroy everything!" The desire for destruction instantly dominated Flandre's mind. The sword of flames in her hand slashed towards Remilia, and Flandre's sword of flames seemed to be able to incinerate even space, making Remilia feel an exceptionally powerful threat.

This Flandre has become this strong... Looks like I'll have to ask Yukari about the situation next time I see her!

Remilia snorted coldly and threw Gungnir in her hand towards Flandre.

"Shoot to Kill - God Spear!"

The shockwave from the collision between Gungnir and the sword of flames distorted the surrounding space, but it didn't affect the battle between Artoria, Mash, and Cú Chulainn. After all, these two were big shots who could fly, and their fighting wouldn't affect the ground.

The collision of the two energies seemed to indicate that the latter was stronger. Flandre, with a twisted smile, shattered Gungnir, which was formed from magical power, and continued to charge towards Remilia without hesitation.

Endless destruction dominated her everything. All she wanted to do now was destroy everything in front of her.

Although Remilia's expression changed, she quickly recovered completely. At the same time, Remilia stretched out her hands, and immense magical power overflowed from her body.

"Vast Killing Array - Scarlet Nevernight!"

Instantly, a violent impact force was released with Remilia as the center, but the smile on Flandre's face remained unchanged. The sword of flames seemed to be unimpeded in any way. Then, a red light as bright as blood bloomed from Remilia's body.

The next moment, a huge, bloody cross rose from the ground, and red beams of light, all gathered from spiritual energy, released a terrifying pressure. This red spiritual energy completely enveloped Flandre.

Almost simultaneously, a giant composed of pure wood threw Artoria into its center, and a massive explosion erupted from within, under Artoria's astonished gaze.

Gradually, the smoke dissipated, and Artoria, her body slowly transforming into photons, reappeared before everyone.

"Hmph. It seems I unconsciously held back. I failed to strike the final blow at the last moment. Though I desired to protect the Holy Grail, I ultimately failed due to my own excessive obsession." As if mocking herself, Artoria offered a wry smile. "In the end, no matter how fate changes, as long as I am alone, will I always meet the same end?"

"Huh? What do you mean by that? What do you know, you?" Cú Chulainn frowned slightly.

"Someday you will know, Child of Light of Ireland," Artoria said faintly, before uttering a phrase that shocked Olga Marie. "Grand Order… the war revolving around the Holy Grail has only just begun."

"Hey, wait a minute, what exactly is…" Before Cú Chulainn could finish speaking, his own body began to dissipate, slowly turning into photons. "Damn it, forced return at a time like this!?"

"Tch, hard to accept, but can't be helped! Kid, little girl, I'm counting on you next! If there's a next time, summon me as a Lancer!" Cú Chulainn said with a faint smile.

As soon as he finished speaking, Cú Chulainn disappeared before everyone's eyes.

Mash was just about to say something when Koizumi's shout came.

"Milady!"

Mash and the others quickly turned their gazes to the other battlefield.

Remilia's chest had been pierced by Flandre's Flame Sword, and Flandre was looking at her own body in astonishment. Her upper and lower body had been forcibly separated by a gap, and blood splattered on Remilia, but Flandre seemed to feel no pain, only surprise.

Seeing this, even Remilia, who had been pierced by Flandre, couldn't help but feel a surge of anger in her heart.

"You really dare to do it… Gap Youkai…"

"You really dare to do it… Gap Youkai…"

A thick anger appeared on Remilia's face, and the killing intent in her eyes was obvious.

For Remilia, her younger sister was always the most important person in her heart, and now someone dared to hurt her!

Even though she knew that the other party probably did this just to directly repel Flandre, after all, she had been defeated by Flandre, so the only one left on the scene was that girl named Mash, who was no match for Flandre.

Even if that shield that could block the Holy Sword could block it for a while, it would be useless.

But… that couldn't constitute a reason for the other party to hurt Flandre like this!

However, no matter how angry she was, Remilia had already begun to dissipate. Flandre's attack had shattered her Spirit Core.

"So I can only… retire here…"

Despite all her unwillingness, Remilia could only go this far.

After all, no one had expected to encounter Flandre.

Gradually, Remilia's body slowly turned into photons and dissipated, and the same was true for Flandre.

"Oh, is Flandre going to disappear with her sister too? Hmm, she didn't merge with her sister… but… it's okay as long as she's with her sister!" Flandre still had that twisted smile, but—

Flandre's words made Remilia pause slightly, then reveal a gentle smile.

"Yes! No matter where, your sister will always be with you, Flandre…"

After saying these words, Remilia embraced Flandre, her face always carrying a gentle smile.

In any case, she would never be able to make up for her debt to her younger sister.

But no matter what, this love for her sister would not change in the slightest in Remilia's heart.

Even if Flandre did something too much, as her sister, all she could do was be infinitely tolerant and responsible for pulling her sister back on the right track.

When I am summoned next time, I will pull you out of the darkness.

Muttering to herself in her heart, Remilia couldn't help but glance at Koizumi to the side.

It's a little regrettable, I hope he can leave here safely and regain his memory.

However, before Remilia could say what she wanted to say, she and Flandre disappeared from here.

The moment Remilia disappeared, Koizumi's heart couldn't help but ache. They were separating so soon.

What was even more infuriating was that even though he had been by her side for a while, she didn't say a word to him.

"Koizumi-san…" Mash couldn't help but look at Koizumi with a worried expression. She could also see that Koizumi had a relatively strong feeling for Remilia, so she was very worried about Koizumi's condition when she saw Remilia disappear.

"Are you okay?" Ritsuka couldn't help but step forward to ask.

"I'm fine…" Koizumi forced a smile, but Olga Marie seemed a little absent-minded.

Just then—

Koizumi's body began to emit bursts of light, as if he was about to dissipate like a Servant disappearing.

"Koizumi-san… what's going on?" Mash and the others were immediately taken aback, and even Olga Marie was awakened.

"Hey! Dr. Roman, what's going on with Koizumi?" Ritsuka quickly asked Dr. Roman, who was in Chaldea.

And Dr. Roman seemed very surprised, and a look of astonishment appeared on his face.

"I don't quite understand either. He's not a Servant, but this state is a bit like a forced return of spiritron transfer…"

"What…" Olga Marie and the others were surprised, while Koizumi silently looked at his hands.

Suddenly, a look of helplessness appeared on Koizumi's face. His life really wasn't in his own hands at any moment. He came to this place inexplicably, met Milady inexplicably, and disappeared inexplicably.

My life is truly full of inexplicable things at every turn.

"Sorry, I don't quite understand what's going on, but..."

I'm glad I could meet you all. At least, meeting you all felt so natural.

Before he could finish speaking, Koizumi's body turned into photons and dissipated before Ritsuka and the others' eyes.

Here was a snow-white space. Koizumi was sleeping in this space, and a figure stood beside Koizumi.

That figure had her golden hair coiled up, held a large parasol in her hand, was tall, about seventeen or eighteen years old, and wore a pink and white princess dress with frills. On the front of the pink and white frilled princess dress was a Taoist robe draped with Bagua symbols. She wore a pink and white frilled top hat, with a red ribbon tied into a bow at the front, adding a touch of cuteness to this seemingly noble girl.

Slowly, two small orbs, radiating blue and silver light respectively, appeared behind her.

"Still using this form, Gaia, Alaya..."

The girl said this, with a hint of helplessness in her tone.

"You really can do it, aren't you afraid that vampire will come looking for trouble? Although, strictly speaking, that one isn't her sister, just watching someone who looks like her sister die is also a kind of pain for that vampire."

The blue orb trembled as it spoke.

At the same time, the two orbs were gradually covered by light. When the light dissipated, a blue-haired girl and a silver-haired girl appeared before this girl.

The two looked almost identical, the only difference being their hair color.

"So what? In that situation, it seems there's no better way than killing the other party. It's already clear that Remilia is no match for her." The girl said softly, while glancing at Koizumi, who was sleeping, with a strange light flashing in her eyes. "Anyway, I'm letting her prepare herself mentally in advance. That Flandre, she's destined to be our enemy. She's simply an existence that Gensokyo doesn't need."

"That makes sense." The silver-haired girl—Alaya—said calmly.

"Hmm~~"

At this moment, Koizumi couldn't help but groan, a look of pain on his face.

"He's waking up." Alaya looked at Gaia beside her. "Shall we leave?"

"Let's leave. Anyway, Yukari is here to explain, so there's no need for us to meet him."
