Shirou, who returned from the Fairy Kingdom

Shirou waited until the enemy was close enough to fire his weapon, using only the initial burst of power to kill the beast right in front of him.

This way, the interference of the blizzard on shooting can be minimized.

"........."

Even though it's a very simple principle, how much confidence does it take to actually do it?

Shirou gripped the chains and swung the "Chaos Blade" like a hammer.

"Well!"

Unable to get close, Flöf was forced back again, and then Shirou glared at Nero with his burning golden eyes.

"!"

Beastly instincts caused the Black Dead Apostle to abruptly take a step back.

But it is already late.

Shirou's "Chaos Blade" has reached its maximum speed.

"——————!"

Nero Chaos's entire body was cleaved in two diagonally from the shoulder by the flying chain blade.

"ah!!"

With a piercing scream, Nero leaped backward.

His body was missing halfway from his shoulders to his waist, leaving a very flat cross-section.

As for the severed part of the body, it simply fell onto the snow.

Although Nero Chaos already knew about Shirou Amamiya's strength, he still underestimated his power.

Even when attacked from both sides by two of the Twenty-Seven Ancestors, he was still able to organize a counterattack with ease.

However, this level of power alone is insufficient to kill the twenty-seven patriarchs.

Nero Chaos reappeared in the blizzard as if he were unharmed.

Like the beast corpses, his severed half of body turned into black slime and returned to his original form.

"Haa...haa..."

Shirou adjusted his breathing, a dull pain throbbing in his lungs.

The Einzbern family's heirloom thermal attire has been ineffective since just now.

Even an alchemical masterpiece couldn't last long at minus 100 degrees Celsius.

"I admit I misjudged; it's unbelievable... that mere humans could possess such formidable strength."

"Truly worthy of being the inheritor of the Mystic Eye of 'Brunstad the Crimson Moon.' If it had been some other Dead Apostle instead of me today, you would probably already be dead."

Nero's voice showed no sign of fatigue.

This is the difference between the highest-ranking Dead Apostles and humans.

For them, who are immortal, the concept of "physical strength" simply did not exist from the beginning.

Furthermore, Nero Chaos is arguably the most eccentric among the Twenty-Seven Ancestors.

"Is that your 'Principle Blood Ring'?"

Shirou stared at the blackness of Nero Chaos's coat and asked.

This is a tactic to buy time and allow the body to recover.

It might not be very useful against a sharp-witted warrior like Floff, but it could be used against a self-important magician like Nero Chaos.

"To be able to see through my true nature at a glance—you are the first in thousands of years, Shirou Amamiya."

Nero Chaos's usually cold, almost corpse-like face now showed undisguised admiration.

"If you're so inclined, then you can record the number of 'beasts' inside me."

If we use human numbers to represent it, it's six hundred and sixty-six.

"Hmph, this is the amount of chaos within me."

Heinrich Zeppelin's madness pales in comparison to that of Nero Chaos.

Shirou said in a deep voice, "Did you mix more than six hundred beast factors into your soul when you were still human?"

Nero Chaos nodded: "That's right. It's similar to the 'Land of Creation' or the 'Primordial Sea'."

I did not transform other animals into my physical body, but rather I encapsulated their genetic material into "chaos" and used it as my "physical body".

I don't have any so-called familiars, only a group of 666 beasts—and 666 lives.

It doesn't matter if the body is broken in half or the head is shattered.

I am one person, and also six hundred and sixty-six wild beasts.

"To destroy me, you'd have to wipe out all 666 lives within me in an instant; otherwise, it's impossible."

"Beast King's Nest"

The "Blood Ring of the Principle" held by Nero Chaos.

It was originally a natural barrier hidden within itself, thus avoiding the world's correction.

He caused the essence of 666 wild beasts to swirl within his body, as if he possessed as many as 666 lives.

Using 666 beast factors inside the body, beasts are created, and the released beasts are used for reconnaissance, attack, or devouring humans.

Since he has merged with the beast factor, the beasts he releases are considered part of his body, not familiars.

The beast factor within the body has no fixed form. The beast that is released and transformed into it will not be destroyed even if it is killed externally, as long as it returns to its original form in the chaos at the core.

Therefore, to completely kill Nero, all 666 lives must be wiped out in an instant.

To do that would be as absurd as destroying an entire continent.

Shirou gasped, "Who are you?"

"Who am I? This question is meaningless."

The Black Dead Apostle slowly said, "What appears before you now is not an 'individual'."

The person called Nero does not exist; I am closer to a "group" than an "individual."

Indeed, to you humans, life that has become like this has lost its so-called meaning of existence.

The magician who first sought immortality has long since sunk to the deepest depths of the "Primordial Sea."

This is the truth about Nero Chaos, which is why the Church gave him this name because his existence is like the primordial chaos of the universe.

"But don't you think that's what makes it so wonderful? A chaotic mess, like something that doesn't know what it's going to become, is churning inside me."

This is comparable to the small world at the beginning of creation.

This chaotic state, from which no known life forms may arise, holds unimaginable possibilities, much like Earth's life system tree.

I absolutely must witness my final fate before I disappear.

"You really know how to talk a lot. Were you a professor at the Wandering Sea when you were alive?"

Shirou smirked: Thanks to you, my reply is complete.

He is now just an ordinary person who has trained since childhood.

His talent as a first-generation magician was quite outstanding, but he was far from being comparable to the nobles of the Clock Tower.

Normally, Shirou can only replenish his mana by using mana replenishment after he runs out of mana.

However, he now possesses a new ability: a contract with "Winter Saintess" Justeza.

As Shirou's familiar and also the Third Magician, Justessa possesses boundless magical power.

Although its output efficiency is laughably low, its total magic power is even greater than that of Albion's heart.

After Shirou became the master of the "Winter Saintess", an invisible causal line connected them.

Even though they were separated by the entire Eurasian continent, Justeza could sense Shirou's call and let her magic flow into Shirou's body through the causal threads.

During the Fourth Holy Grail War, Lady Avalon once used this method to reverse-supply magic to Shirou.

After trying it with Justissa, he discovered that she could do the same thing.

Although it was mentioned earlier that the "Winter Saintess" has a low magic output efficiency, that is relative to the average magician.

Coincidentally, Shirou is only a third-rate magician, so he is better than anyone else at using small amounts of magic sparingly.

"!!"

Nero Chaos's eyes widened in surprise.

A golden glow emanated from Shirou's right palm.

The light was too dazzling for the vampire to see, and Floff shielded his eyes with his arm.

"What... is that...?"

"Kill 666 lives at once? No need for that kind of trouble—"

"Just evaporate your entire world, okay?"

Shirou raised the final, strongest sword, now fully projected.

"—The Divergence of Heaven and Earth, the Star of the Oath (Enuma Elish)!!!"

------------

Volume 6, Chapter 289: Morgan: I'm making a limited-time comeback in the form of a fairy princess.

Ea (頕銀).

This is the only item that the oldest king, who collected all the treasures in the world, kept alone in the deepest part of his treasury.

The hero-king Gilgamesh called it his half-body, and whether it was truly a sword is unknown.

That was the embodiment of the power wielded by the gods in the primordial chaos before the birth of humankind, to create the world.

The sword of heaven and earth that cleaved the beginning of everything on this planet.

Cut through the void and create the sky, penetrate the sky and return to the void.

Symbolizing the power of beginning and end, it can only be used by Gilgamesh, who inherited the divine essence.

Therefore, when this sword is released, it will be classified into the following categories.

Opposing Noble Phantasm.

In stark contrast to Karna, the son of the sun god, whose annihilating spear "completely destroys the existence of a single individual."

The sword of discord holds the concept that "regardless of whether the opponent is an individual or a group, it will disintegrate the world to which it belongs."

Ea is a natural enemy of Nero Chaos, who transformed his own body into a chaotic world.

Nero Chaos once proudly proclaimed that his "principle" was "the earth of creation, the primordial sea," so—

The red-haired boy pulled out the golden sword that had been projected.

"Kill 666 lives at once? No need for that kind of trouble—"

"Just evaporate your entire world, okay?"

The three cylindrical sections of the Ea sword began to rotate, and the atmosphere roared in response.

As a large amount of air was forcibly drawn into the Ea, the surrounding physical laws began to melt and break, forming a distorted force field that tore through dimensions.

"—The Divergence of Heaven and Earth, the Star of the Oath (Enuma Elish)!!!"

Shirou shouted and swung the counterfeit Ea.

The laws compressed to their limits were released at this moment, transforming into a crimson tornado that cleaved the world in two.

The "first strike" known as "the creation of the world" depicts the true scene of creation.

Space itself shatters like glass wherever the wind pressure hits, creating rifts in spacetime and gaps in cause and effect, and the world itself is turned upside down.

The snowfield and the earth crumbled like clay, and the blizzard and the black beast herd were easily torn apart.

It's like a landscape painting on paper that's been blended in a blender; it's more like the end than the original.
