FGO System in the Type-Moon World

"You're saying you want to fight all three of us alone?"

Diarmuid frowned, his grip tightening on his spears.

He despised unfair fights.

Ganging up on a single opponent left a bad taste in his mouth.

But the situation before him was clearly unbalanced.

Yet—

Reiji merely shook his head, gazing at him as if he were a fool.

"One versus three?"

"When did I ever say that?"

His mocking tone left both Artoria and Diarmuid stunned for a brief second.

Only Iskandar seemed to sense what was coming.

And then—

Reiji smirked.

"If we're going to fight…"

"Then it'll be three versus three."

His arms spread wide, his voice brimming with confidence.

"Berserker, you take the Lancer."

Berserker cracked his neck, his excitement clear as day.

Though classified as a Berserker, his fondness for spear battles remained intact.

Now that he had a worthy opponent, he didn't hesitate for a second.

He charged straight at Diarmuid.

"As for the other two…"

Reiji's grin widened.

Reiji paused for a moment, but before he could speak, Zhuge Liang stepped forward.

"That immature Magus and Rider… I'll handle them."

Reiji glanced at him, then smirked.

"Alright then, go all out."

With those words, he turned his gaze toward Saber.

"Tamamo, she's yours."

Before Reiji had even spoken, Tamamo-no-Mae was already standing in front of him.

Now that he had given the order, she simply smiled.

"If it's Master's command, little Tamamo shall execute it to perfection, de~su!"

With a wave of her hand, several incantations activated—

And her battle with Saber had begun.

Meanwhile, Reiji observed the battlefield from three different perspectives.

Then—

He sat down, assuming the role of a spectator.

But in truth—

Each of them—

Himself, Zhuge Liang, Tamamo, and Cu Chulainn Alter—

All bore a subtle enchantment cast by Tamamo-no-Mae.

This binding spell allowed them to communicate telepathically without uttering a word.

And at that moment, Reiji sent his first message.

"Zhuge Liang, don't push too hard. Your only job is to stall them."

"I already said it before—it's not time for him to be eliminated yet."

Hearing Reiji's voice in his mind, Zhuge Liang smirked faintly.

Then—

He turned to Waver Velvet and raised his voice.

"You—Master over there! Why are you panicking?!"

"You can't even handle your own affairs properly, and yet you rushed into the Holy Grail War on impulse?!"

"Do you have any idea how utterly foolish you are?!"

At this moment, Zhuge Liang's mindset had already shifted.

And precisely because of that, he knew this tactic would work.

Tamamo vs. Artoria

Tamamo-no-Mae's battle with Artoria was actually quite simple.

Her attacks were primarily spells, but Artoria possessed high-level Magic Resistance, making them mostly ineffective.

However—

Tamamo had plenty of defensive and supportive spells.

And combined with her shapeshifting abilities, Artoria couldn't easily deal with her.

No—

To be precise—

She couldn't deal with her at all.

At this moment, one of Artoria's hands was permanently wounded, meaning—

She couldn't unleash her Noble Phantasm.

Without Excalibur, Artoria posed no threat to Tamamo.

Though Tamamo wasn't in a position to finish her off immediately,

If the battle dragged into a war of attrition,

Tamamo—who had unlimited magical energy thanks to her Noble Phantasm—

Would undoubtedly hold the advantage.

Against Artoria, Reiji's strategy was identical to the one he used against Iskandar.

"Tamamo, just keep her occupied."

"Don't be reckless. Don't overextend yourself."

"Because—our real target is already caught in the net."

Reiji only glanced at the other two battles for a moment.

Then—

He focused entirely on Cu Chulainn Alter vs. Diarmuid.

Because as he said—

Now that the battle had begun, someone had to be eliminated today.

And that person—

Would never be him.

Diarmuid—A Doomed Warrior

Was Diarmuid weak?

No.

His personal combat ability was outstanding.

With two spears, one that nullified magic and one that inflicted incurable wounds,

Paired with exceptional martial skill,

He was a powerhouse in single combat.

But unfortunately for him—

His opponent was Cu Chulainn Alter.

A Battle of Spears

Among all Servants—

Diarmuid's worst possible matchup was Cu Chulainn.

Both were agile spearmen with high-speed combat capabilities.

A fight between them should have been—

A fierce, evenly matched duel where neither could land a decisive blow.

However—

Cu Chulainn possessed something Diarmuid did not.

His Noble Phantasm, Gáe Bolg, was guaranteed to hit.

Unlike Artoria, Diarmuid lacked the Instinct skill.

And that meant—

From the very beginning, he was already at risk of being one-shot.

Worse still—

His opponent wasn't normal Cu Chulainn.

This was Cu Chulainn Alter.

As a Berserker, Cu Chulainn Alter surpassed Diarmuid in every stat except agility.

Once the battle began—

Diarmuid was completely overwhelmed.

His spears required passive activation.

But once Cu Chulainn understood their abilities,

He immediately rendered them useless.

A One-Sided Slaughter

If this had been a battle of attrition, Diarmuid might have stood a chance.

But here—

Tamamo's Noble Phantasm had already covered the battlefield, eliminating any magic costs for allies.

Cu Chulainn Alter could spam Noble Phantasms endlessly.

Diarmuid, on the other hand, could not.

Diarmuid had to carefully manage his magic energy,

Ensuring he didn't overburden his Master.

But Cu Chulainn Alter?

He had no such worries.

This battlefield was Reiji's trap.

And there was no way he would allow this to become a prolonged fight.

Reiji grinned.

Then—

He cast two buffs on Berserker in quick succession.

One: Attack Enhancement.

Two: Evasion Enhancement.

At that moment—

Cu Chulainn Alter felt his strength surge to nearly double its normal power.

His entire being crackled with energy, like a storm ready to explode.

It was as if a glowing '+' sign had appeared next to all his stats.

Against most Servants, such buffs wouldn't mean instant victory.

After all, most battles were decided by Noble Phantasms.

But against Diarmuid, whose Noble Phantasms couldn't turn the tide of battle—

This enhancement was nothing short of fatal.

To make matters worse—

Reiji's buff also granted Berserker an evasion effect.

And now—

Diarmuid's doom was sealed.

For One Minute—Cu Chulainn Alter Was Untouchable

For a full minute, Cu Chulainn Alter abandoned all defense.

After all—

His body would react on its own, effortlessly dodging every attack within that timeframe!

Realizing that this was a buff granted by Reiji,

Cu Chulainn Alter's eyes widened, and a wicked grin spread across his face.

There was no need to care about Diarmuid's twin spears anymore.

At this moment—

He focused everything solely on his attacks.

His movements accelerated, growing even faster and more relentless.

"Hahaha! AHAHAHAHAHAHAHA!!"

His wild laughter echoed across the battlefield.

Meanwhile—

Diarmuid began to struggle more and more to keep up with his opponent's pace.

Then—

The tempo reached its peak.

Cu Chulainn Alter's red spear tore through the air—

And as it frictioned against the wind, it ignited into steam and flames.

At that moment, Diarmuid's eyes widened in terror.

He saw the murderous, blazing lance rushing toward him.

He barely managed to tilt his head to avoid a direct hit—

But the razor-sharp fangs protruding from the spear ripped into his neck.

Not a fatal wound for a Servant.

But Cu Chulainn Alter wasn't about to let this opportunity slip away.

A Storm of Spears

He planted his feet firmly, locking himself in place.

Then—

His spear lashed out like a fully-automatic Gatling gun, delivering an unrelenting barrage of thrusts.

In that brief moment—

Even Cu Chulainn Alter himself had no idea how many times he had struck his opponent.

Diarmuid was overwhelmed instantly.

He had no chance to utter his final words.

His body was sent flying through the air, only to collapse lifelessly onto the ground—

Where it dissolved into golden light, vanishing into the Throne of Heroes.

The Battlefield Falls Silent with Diarmuid eliminated, the other two fights came to a natural halt.

"I can't believe he actually took down Lancer…"

Artoria furrowed her brows, flexing her gradually recovering hand,

A rare trace of genuine admiration flickering across her face.

Watching this unfold, Iskandar walked to Artoria's side.

"Oi, little lady."

"You've seen it with your own eyes now, haven't you?"

"If we don't join forces, we're going to be taken out one by one."

Artoria's grip on Excalibur tightened.

But before the tension could escalate further—

Reiji narrowed his eyes and smirked.

"No need to be so tense."

"I said one faction would be eliminated today."

"Since he's already out… you two are free to leave."

With a snap of his fingers,

Zhuge Liang dissolved the Stone Sentinel Maze.

"Every Enemy Deserves a Proper Burial"

Reiji's voice carried a teasing tone.

"I have a personal habit."

"I like to choose the perfect graveyard for every enemy I defeat."

He grinned wickedly.

"And frankly, I don't think this place is yours."

"So, I suggest you leave."

"Of course…"

Reiji's smile deepened.

"If you'd rather continue fighting—"

"We're more than happy to oblige."

Reiji's Third Reward

With Diarmuid's death—

Reiji finally obtained his third Saint Quartz.

Without hesitation—

He upgraded Zhuge Liang to a System Servant.

At the same time—

A new system reward appeared.

[Congratulations, Master, on successfully summoning Zhuge Liang!]

[Reward: Phasing (Allows the user to shift into a separate dimension, rendering all attacks ineffective against them)]

With this new ability,

Reiji's presence itself became elusive, as if he was half-anchored in reality.

Iskandar Chooses to Retreat

Iskandar narrowed his eyes, his brow furrowing slightly.

But in the end—

He chose not to continue the battle.

"Hahaha! You're quite the formidable one, lad."

"But this king still has unfinished business elsewhere."

"This isn't the time for an all-out war."

His booming laughter filled the air,

Before he rode off on his divine chariot, disappearing into the night.

Seeing Iskandar leave,

Artoria sensed Irisviel's presence in the distance.

After a brief farewell,

She too turned and departed.

Reiji's Next Target—Tokiomi Tohsaka

Watching them disappear into the distance,

Reiji wiped his nose with a smirk.

"Hmm…"

"I let Kirei go so he could deliver the bad news to Tokiomi."

He chuckled darkly.

"By now, the message should be delivered."

"Which means…"

"It's about time we paid a visit to the Tohsaka family."
