Using FGO to Open the Second Dimension

Gaia said indifferently, her gaze towards Koizumi devoid of any emotion.

"Just a weapon, nothing more. There's no need for us to get involved."

The girl called "Yukari" frowned slightly, but didn't say anything.

Alaya nodded, then disappeared with Gaia.

The girl called "Yukari" glanced at Koizumi, shaking her head with a wry smile. "A weapon, huh… Isn't it a bit early to make such a judgment, Gaia?"

Everything was hazy before Koizumi's eyes. He couldn't help but rub them, and when his vision cleared, he realized where he was… a snow-white space, and he was floating in the air.

But there was a girl in front of him who felt strangely familiar. If not Remilia… then who?

"You…" Koizumi had just started to speak when the girl held a finger to his lips.

"My name is Yakumo Yukari, my class is Ruler. Like Remilia, who you met before, I'm a Servant… Although, as the main body, I'm rather weak in this form, but if I were to use my full power, it would be too unfair."

The girl—Yakumo Yukari—said with a smile.

"Servant… Miss Remilia, she…" Speaking of Remilia, Koizumi couldn't help but feel a little saddened.

"Don't worry, you'll meet again. After all, it's just a Servant, not the main body. There's no such thing as true death." Yakumo Yukari said casually, which ignited a spark of hope in Koizumi's heart.

There's still a chance to meet! Koizumi thought to himself.

Seeing the change in Koizumi's expression, Yakumo Yukari just smiled faintly and didn't say anything more.

The next moment, a rift opened in front of Yakumo Yukari, a rift filled with eyes.

"This is…" Koizumi was slightly stunned. Before he could react, Yakumo Yukari pulled him straight in.

"Don't worry, I won't hurt you."

Yakumo Yukari said with a smile, but Koizumi couldn't help but feel that she was a little untrustworthy.

After passing through this creepy

Gap

filled with eyes, Koizumi's eyes suddenly lit up.

This was a place full of high-tech equipment. The instruments in front of him alone were dazzling.

"Where is this…" Koizumi muttered to himself, scanning his surroundings.

"Chaldea… Well… it should be called Simulated Chaldea. It's exactly the same as the place where that Fujimaru Ritsuka you know is. It's a new space I created, and everything inside is a simulation of that place called Chaldea. After all, their instruments are really useful." Yakumo Yukari said casually, her tone filled with deep admiration.

"I feel like it's strange for you to use these…" Koizumi couldn't help but complain.

"That's true. After all, it's a bit strange to see a youkai using high technology."

Yakumo Yukari didn't deny it, but nodded gently.

"Alright, Little Koizumi, sit down and relax for now. The topic we're going to discuss next is very heavy and contains a lot of information. I'll explain it to you slowly." As she said this, Yakumo Yukari took out a folding fan from somewhere.

Then, with a flick of her wrist, she opened the fan and used it to cover her mouth, her eyes revealing a strange meaning.

"What do you mean? Do you know something about me?" Koizumi seemed very excited, but this was normal. Koizumi only knew his name and nothing else about himself. Now that he finally had a chance to learn about his past, how could he not seize it?

Thinking of this, Koizumi's gaze subconsciously drifted to the Command Seals on his left hand, where two remained.

If he could, Koizumi would not hesitate to use a Command Seal to force her to tell him about himself.

Yakumo Yukari took in Koizumi's every move, then shook her head gently and sighed softly.

"I don't know much about your past. After all, I was summoned by you. All I know is what you need to do next, so I might have to disappoint you."

"Also, it's useless for you to use Command Seals on me. Command Seals have a great binding force on Servants with low levels of magic resistance, but for me, even if you use all three together, they won't have much effect."

Yakumo Yukari's words immediately dispelled Koizumi's thoughts. Regardless of whether what she said was true or not, if he used them, he might end up falling out with her. Koizumi's intuition told him this.

Prosperous Illusory Empire - Imperial Capital

Prologue Traitor Akame

In the jungle, a figure was running at high speed, with two swords at their waist.

Looking closely, it was Akame, a girl almost entirely dressed in black except for the red wristbands on her hands.

The girl's running speed was exceptionally fast, and ordinary people couldn't catch sight of her.

From the girl's breathing, it could be heard that she was very anxious, and her usually calm face faintly revealed worry.

The next moment, a rustling sound came from behind her. The girl was suddenly startled, but she didn't stop her pace. She just gripped the hilt of one of the swords in her right hand.

Several figures rushed up at an extremely fast speed. One of them, a girl with long hair and wearing some kind of gauntlet on her hand, was the fastest and punched towards the Akame girl with a look of anger on her face, without any hesitation.

"Boom!"

The girl only drew the sword slightly, using the blade to block in front of her, but she was still sent flying by the punch. Her feet slid backward, and the girl barely managed to stabilize herself, but looking at the tracks on the ground, she had still been knocked back several meters.

Feeling the power within the other party's body, the girl couldn't help but reveal a bitter smile.

"Korr-nee can actually knock me back. This enhancement ability is really…"

"Stop right there!!!!!!" Under the roar of the long-haired girl wearing gauntlets, the Akame girl's expression sharpened, and she decisively drew one of the swords from her waist, assuming a fighting stance.

In an instant, the Akame girl was surrounded by four people, and none of them underestimated her. Clearly, the Akame girl was worthy of their attention.

"This is really… Korr-nee, Nahashu, Tsukushi, Pony…"

The Akame girl immediately smiled bitterly, but there was no slackness on her face.

Having been their comrade, she undoubtedly knew their strength better than anyone.

Although the thought of fighting her former friends stirred complex emotions, there was no question that if it came down to a life-or-death struggle, this Akame would not hesitate. Because—she had a reason she couldn't die here.

In a flash, Akame appeared before one of the imposing men, her katana slashing without hesitation, a myriad of cold glints appearing in the blink of an eye.

Even he was slightly taken aback to see his former teammate displaying such power.

"A small fry who was holding back all this time, huh!"

The man exclaimed, his weapon—the Water Dragon Sword—meeting her attack without hesitation.

Faced with such strength, he couldn't afford to consider whether he should hold back just because she used to be a friend.

"Nahashu, I don't want to fight you! Take Korr, Tsukushi, and Pony and get out of here!"

Akame shouted, but the young man named Nahashu didn't budge.

"Don't joke around, Akame! I haven't avenged Grimm and Guy yet! You killed Grimm and Guy, killed Father, and stole a Teigu from the Empire. What do you want? Are you betraying the Empire?"

"I…" Akame paused, a scene of Guy and Grimm being killed by her flashing through her mind, a look of pain crossing her face, but it was quickly replaced by determination.

"I have things I need to do. Don't stop me—"

With that, Akame forced Nahashu back with a strike, sheathing her katana and quickly drawing another katana that exuded an ominous aura—One-Strike Kill - Murasame.

"This Teigu is called One-Strike Kill - Murasame. I don't want to hurt you with it. Leave now and don't follow me!" Akame said, pointing Murasame at them and slowly retreating.

They had all heard of Murasame. One-Strike Kill - Murasame was a Demon Blade in every sense of the word. Anyone cut by it would be infected with a curse poison from the wound and quickly die, with no antidote.

Nahashu and the others wielded Shingu, which were not particularly powerful in terms of effects and abilities, at least compared to Akame's Murasame. Moreover, Akame had another weapon—the Shingu Kiriichimonji.

The Shingu Kiriichimonji, while lacking the guaranteed death effect of a Teigu, would create wounds that could not be healed.

"I can't believe Akame can adapt to a Teigu. It's incredible," Tsukushi remarked.

"Whatever, I want to see if this Teigu is really that strong!" Pony pouted, expressing her dissatisfaction, and charged forward without another word. Her speed was actually faster than the others.

"Pony, fall back!" Nahashu's expression changed drastically. Having just exchanged blows with Akame, he was well aware of her strength. If Akame hadn't been using a Shingu instead of a Teigu, he might have already been in trouble.

As if she hadn't expected the other girl to charge forward, Akame's expression also changed slightly.

Quickly gripping the hilt with her left hand, Akame's right hand grasped the scabbard of Kiriichimonji and drew it without hesitation. She had only used Murasame to make them wary, but she had forgotten about Pony.

Pony was always a bit of an airhead. Even if she saw Akame draw a Teigu, she wouldn't retreat so easily.

Akame slightly sidestepped, brushing past Pony. However, in the instant they passed, Akame struck Pony in the abdomen with the scabbard of Kiriichimonji. The powerful impact sent Pony flying.

Cornelia paused slightly, a strange look flickering in her eyes, before catching the flying Pony.

"Akame…"

Cornelia murmured. If Akame was really as she thought, that blow should have killed Pony. But Akame had only used the scabbard of Kiriichimonji to knock Pony away, without even intending to harm her. Was she wrong about Akame?

Akame sheathed her weapons, glancing at them with a complex expression.

"Don't follow me…"

Akame said softly, before disappearing from sight in a flash.

"When did Akame become so strong…" Tsukushi muttered. She had been closest to Akame in the team, so she was undoubtedly the saddest and most hurt by the betrayal. But she didn't understand at all. They had been fine just a few days ago, so why would Akame suddenly choose to betray them?

And more importantly, why had Akame's strength suddenly increased to such an extent?

The Akame of the past was no match for Nahashu, but the current Akame could easily suppress him.

Was it the Teigu's enhancement? But Akame hadn't used a Teigu just now.

Nahashu and the others fell silent, especially Nahashu, who had felt Akame's power most keenly.

"Should we still follow her?" Pony glanced at the others, mostly looking at Nahashu.

Nahashu was undoubtedly the leader of the group, and they mostly followed his lead.

"Let's go back…" Nahashu finally said after a long pause.

Cornelia and the others nodded and left with Nahashu.

Sensing the disappearance of the four figures behind her, Akame secretly breathed a sigh of relief and continued to hurry forward.

She still had many things to investigate and didn't have time to stay here for long.

As for what she needed to investigate, it was already obvious.

For example… the affairs of this Empire…

And for example… the current whereabouts of Kurome…

And for example… what exactly was going on right now…

However, it seemed that reality wouldn't allow her to do so.

After passing through the forest, an icy blue figure made Akame freeze in shock.

Why was she here, waiting to ambush her? No, according to her memories, she should be…

Why was she here? Why was she wearing that nostalgic expression? Why, why, why…

Too many questions filled Akame's mind, but right now, Akame only understood one thing, and that was—

——She was his enemy right before his eyes——

"—Bury them!!!!!!!!!!!!!!!!!!"

Without hesitation, Akame drew Murasame and faced the ice-blue figure before her.

Chapter 12: Koizumi Falls into Helplessness

Just as people decay, so too will nations eventually meet their end. Even the Imperial Capital, prosperous for a thousand years, is now nothing more than a corrupt hell on earth, where ghouls in human skin strut about arrogantly—

A gentle breeze blows, and warm sunlight covers the earth. Little sprouts emerge from the grass, bathed in the sun's rays.

A new day dawns, and the gates of the Imperial Capital open. In the bustling metropolis, residents begin to busy themselves with their livelihoods. All sorts of people walk the streets, and the recruitment grounds are packed with crowds eager to make a name for themselves.

Within the Imperial Capital, there are two rather peculiar shops. One is labeled "Hakurei Amulet Shop," and it's filled with various amulets. Rumor has it that simply buying one and carrying it with you will ensure your safety. The other is a shop that sells masks, with the sign "Noh Masks" clearly indicating that it's a store that makes and sells Noh Masks.

But, come to think of it, it's obvious that the owners of these two shops have never bought anything themselves, because—

What kind of bizarre shop writes what they sell on the sign but doesn't include "XXXX Shop" or something similar?!

At this moment, Koizumi stands between the two shops, feeling utterly helpless.

He glances at the shops on either side, unsure of what to say.

Weren't they supposed to be resolving Singularities? Why are they fighting in such a strange place...?

Yakumo Yukari explained the current situation to Koizumi: they were in a place called the Type-Moon World. In the various parallel worlds of the Type-Moon World, many unnecessary possibilities had emerged, and some of them contained Relics called Holy Grails. These possibilities were being consolidated into Singularities by the Suppression Force of this world, and what he needed to do was to retrieve or destroy the Holy Grails from these unnecessary possibilities, resolve the distortions, and set the parallel worlds that had deviated from the world's trajectory back on course.

In simpler terms, so-called branch worlds had emerged from the original world line, and these branch worlds were unwanted by the original world. Therefore, he was responsible for putting them back on the right track.

Yakumo Yukari told him that this was a task entrusted to him by the Suppression Force, and that in the process of completing the missions, he would surely understand his identity and all his past memories.

For the sake of his memories, and of course, to survive, Koizumi had to complete these tasks.

As for the so-called "to survive"... that was a given. The world wouldn't keep someone who had no value.

So, no matter the reason, he had to resolve these Singularities, just like before.
