FGO System in the Type-Moon World

After summoning Zhuge Liang, the system remained silent.

No notifications.

No new rewards.

Clearly, Zhuge Liang wasn't counted as a system Servant—

Which meant he wasn't linked to the system's mechanics.

Three Saint Quartz.

That was now his immediate goal.

If it were any other Servant, he wouldn't be in a rush.

But this was Zhuge Liang.

A Servant worth investing in.

And with the addition of a new team member, it was time to assign roles.

Tamamo disliked workshop-style bases, but her healing and defensive capabilities were invaluable.

Additionally, she could manipulate various elemental spells, making her ideal as Reiji's personal bodyguard.

Zhuge Liang, on the other hand, had a portable bounded field thanks to his Noble Phantasm.

So the responsibility of setting up their battlefield was handed to him.

With Tamamo's Noble Phantasm active, there was no mana drain, ensuring his work wouldn't interfere with hers.

And Berserker?

His role was the simplest of all.

He spoke only to Reiji.

He ignored everyone else.

And he lived only to fight.

He didn't eat.

He didn't drink.

He didn't sleep.

All he did was crave battle.

And soon, battle would come.

Reiji needed three Saint Quartz, and he knew exactly how to get them.

With his team now fully formed, the hunt for enemy Servants would begin.

And the Holy Grail War would never be the same again.

...

When the battle would begin, both Casters would move their bounded fields forward, suppressing the enemy territory.

At the same time, Zhuge Liang, Tamamo-no-Mae, and Reiji would fully buff Berserker and weaken their foes.

Under such conditions, Berserker, already a powerful force, would become an overwhelming monster.

Reiji had already mapped out the strategy.

But at that moment—

Zhuge Liang approached him.

"Master, our territory has been breached."

"Over eighty intruders. Judging from their presence… it's a Servant—Assassin, Hundred-Faced Hassan."

Reiji paused for a moment.

Then—

He laughed.

Now that he thought about it—

Back when Fate/Zero and FGO had a crossover event, there was a scene exactly like this.

Hundred-Faced Hassan's Presence Concealment was strong—

But against Zhuge Liang's Stone Sentinel Maze(Noble Phantasm), it might as well not exist at all.

If they had launched a surprise assassination, they might have posed a threat.

But now that they had been detected—

This had turned from a perfect assassination attempt into the worst possible situation for an Assassin-class Servant.

For an Assassin, being caught in an open battlefield was a death sentence.

For a Berserker—

It was the best-case scenario.

Without even changing his expression, Reiji glanced at Zhuge Liang.

"Lord El-Melloi II, how would you handle them?"

Zhuge Liang had anticipated this question.

He calmly laid out his plan.

"If I were alone, I would scatter their already dispersed formation further, then pick them off one by one."

"But with Berserker and Caster present—"

"I propose the opposite—gather them all into one place and eliminate them in one strike."

Hearing this, Reiji grinned.

"To form a strategy like this without even knowing Berserker's full abilities… As expected of Zhuge Liang."

"Do it. Gather them together."

Reiji rose from his seat, stepping toward the temple's grand hall doors.

He looked out over the courtyard, spreading his arms wide.

At his command, two figures materialized beside him.

"I may not enjoy fighting… but if someone dares harm Master, that's an entirely different story."

Tamamo-no-Mae stood at Reiji's side, for once wearing a serious expression.

Behind him, Zhuge Liang observed silently, his thoughts unknowable.

And at the very front, standing directly in front of the temple gates—

Berserker slowly lifted his blood-red spear, its serrated edges gleaming in the moonlight.

The night was still.

Even the wind had ceased, as if sensing the battle to come.

Under Zhuge Liang's command, thick mist began swirling at the temple gates, coalescing into a dense fog.

And then—

The Assassins appeared.

Eighty figures emerged from the mist.

They looked left and right, clearly confused.

But the moment they locked eyes with Berserker—

His glowing red irises burning with pure bloodlust—

They immediately realized the truth.

They had been discovered.

They had walked into a trap.

Hundred-Faced Hassan had a peculiar existence.

Though they appeared as eighty individuals—

They were, in truth, a single entity.

Separated, each individual was weak.

Combined, they had the power to challenge a single Servant.

But—

That only applied to normal Servants.

Facing Berserker, they knew—

They didn't stand a chance.

And so—

They made the smartest possible decision.

The eighty figures scattered, dashing in all directions, trying to flee like fireworks exploding outward.

But—

Reiji had already anticipated this.

With a simple flick of his hand, he activated Momentary Reinforcement—

A surge of magical power flooded into Berserker.

"Berserker, use your Noble Phantasm. Wipe them out."

Berserker nodded once.

Then—

He raised his monstrous spear, adopting a throwing stance.

A single name left his lips.

"Gáe Bolg!"

This wasn't Berserker Cu Chulainn's strongest Noble Phantasm.

But it was the perfect choice for this moment.

An Anti-unit, anti-army, tracking-type spear.

Zhuge Liang's Stone Sentinel Maze delayed the Assassins for a few seconds.

And that was all that was needed.

Because by then—

Berserker's spear was already in the air.

His muscular arm twisted unnaturally, his entire body shifting as he channeled all his might into the throw.

A crimson light exploded outward, moving faster than the human eye could track.

The glow of Runes flickered, immediately healing Berserker's self-inflicted damage.

The excruciating pain was utterly ignored.

And as he grinned—

Time itself seemed to freeze.

A red flash—

Like lightning tearing through the night sky.

And then—

The thunder finally arrived.

In an instant—

All eighty Hassan clones were obliterated.

Not a single one escaped.

Tamamo snapped her fingers.

A gust of wind swept through the courtyard, carrying the shattered remains of the Assassins away.

And as their bodies faded into golden light—

Their presence in the Holy Grail War came to an end.

Reiji had maintained a calm expression throughout.

But now—

For the first time—

He smiled.
