FGO System in the Type-Moon World

A golden radiance erupted.

The unstoppable force of Enuma Elish collided with that light—

And vanished without a trace.

Artoria, Zhuge Liang, and Tamamo all widened their eyes in shock.

A Master Who Uses Noble Phantasms

There was no doubt in any of their minds—

Reiji Souma was an exceptional Master.

His mana quality was unmatched, his mind sharp, and his courage unwavering.

But this…

A Master using a Noble Phantasm?

It was unheard of.

The scabbard of King Arthur—Avalon.

It had been passively stored all this time.

And yet—

Souma had just activated it on his own.

The most shocked of all—was Artoria herself.

Even Gilgamesh's usual arrogance wavered for a brief moment.

But the Black Dog—had no intention of waiting.

The moment Enuma Elish was neutralized, he lunged forward like a tank.

"Tch."

Gilgamesh clicked his tongue.

His golden armor was a high-tier Noble Phantasm in itself, boasting formidable defense.

So—

Tens of golden portals opened at once.

From them, Enkidu—The Chains of Heaven—descended toward the Black Dog.

If there was one flaw in the Black Dog's design—

He still possessed divinity.

If those chains wrapped around him, it would be a serious problem.

"Evasion."

But Souma, having anticipated this, activated his Mystic Code's ability.

A 500% chance evasion buff was placed on the Black Dog.

The divine chains grazed past him, missing entirely.

That—

Was Gilgamesh's first moment of shock.

And then—

Cú Chulainn moved.

With both hands gripping his crimson spear, he—

Drove it downward.

It was definitely time to use Ea—

Gilgamesh motioned to activating Noble Phantasm.

But before Gilgamesh could complete the motion,

Black flames erupted across his body.

A shadowy, obsidian armor rapidly engulfed him.

From his hands, razor-sharp claws emerged.

At that moment—

Gilgamesh sensed danger.

But it was too late.

For the Black Dog's true Noble Phantasm had already been unleashed.

"Curruid Coinchenn (The Beast of Crunching Deathtusk)—"

His entire being succumbed to berserk fury.

Through the glowing red slits in his monstrous helmet,

A murderous crimson light flashed.

Time itself seemed to halt.

A claw—

Another claw—

Each strike was a killing blow.

And with every lethal strike, his carnage did not cease.

The Black Dog's savage roar filled the battlefield—

And Gilgamesh's body began to fragment into golden motes of light.

The legendary King of Heroes—was torn apart.

Even he could not resist the overwhelming physical destruction.

And so, his spirit core shattered,

His essence dispersed back into the Throne of Heroes.

The fate reserved for the fallen.

The execution designed by Reiji Souma himself.
