Shinji Matou at Your Service

In the realm of Mystery, there is a distinction between Magus and Magic users.

However, when it comes to True Magic, there are only Magic users, not magi, because Magic cannot be mastered through mere human effort and research.

It is something beyond human comprehension, a product of accident and coincidence, and thus can only be performed—hence, the title Magic user.

Shinji, Justeaze, and even Touko fall into this category. To put it simply, they are merely proxies for performing Magic.

As for Angra Mainyu, although he could be linked to the Third Magic due to his control over the Great Holy Grail, this wasn't what Shinji was referring to. He was speaking about something deeper.

Angra Mainyu is indeed the demon lord of Zoroastrianism, symbolizing all the evil in the world, and during the Age of Gods, he would have been considered one of the greatest deities. But after the Age of Gods ended, the gods left the present world, becoming divine spirits and unable to interfere with humanity.

Even the Great Holy Grail, a creation embodying the Third Magic, cannot summon a true divine spirit, let alone the real demon lord Angra Mainyu.

So, the answer was clear: the shadow claiming to be Angra Mainyu was not the real deal. It was nothing more than a fake, sacrificial pawn given the name of Angra Mainyu.

The shadow's origins were ordinary, and it had no special talents. It was merely unlucky to have been born in a village that worshipped Zoroastrianism, where it was treated horrifically as a symbol of all evil.

He wasn't a hero by his merit but had been created by the wishes of those around him as an anti-heroic spirit. He was something that should not have existed: a being made up of the collective malice of those around him.

The ignorant villagers had locked him on top of a mountain, gouged out his right eye, severed his arms and legs, and continuously tortured him as the embodiment of absolute evil. His real name had been stripped from him through curses, erasing his very existence. In the end, he became a demon known as All the Evils of the World, carrying the burden of sin as an anti-hero.

This experience was the source of the shadow's pain, hatred, and all the negative emotions.

Upon having his true nature exposed, the shadow exuded a thick killing intent. The hole that had just returned to normal began to turn black once more, and those with weaker wills struggled to maintain consciousness in its presence.

Of course, Shinji, who had long been prepared, was unfazed. He spoke calmly and plainly: "I know a bit about your past, and I sympathize with what you went through. Honestly, if I were you, I'd have gone mad long ago. But unfortunately, like a cancer cell, your very existence is a mistake, and so I cannot let you go."

"Indeed, that's why I curse, why I hate, why I destroy!"

With that, the shadow launched an attack—targeting Shinji's physical body on the ground.

This was the most logical move. A soul needs a vessel to exist in the physical world, and for humans, that vessel is the body. Without a body, even the strongest soul would struggle to exert its power.

Naturally, Shinji understood this principle as well and had already prepared for it. The moment the shadow moved, the Sword of Love came down, splitting the shadow in two.

Yet, the severed shadow did not dissipate. Instead, it split into two, then two became four, four became eight... until countless shadows were filling the area.

Watching this, Shinji clicked his tongue in admiration.

"I wasn't wrong when I compared you to cancer cells. But—what's the use of Shadow Clone Technique?"

As he spoke, the sword in his hand shone brightly, cutting through all the shadows on the ground in one sweep.

"Take that! Forty-meter holy sword, mongrel!"

But as the true final boss of the Holy Grail War, who had been controlling the Great Holy Grail for seventy years, Angra Mainyu wasn't going to be defeated so easily.

No sooner had the shadows on the ground been wiped away than the black sun in the sky began to stir violently, reaching its peak and starting to spew out something strange.

It wasn't black mud!

It was something far worse.

This... was flesh.

It looked like spheres, or perhaps some form of eggs, pulsating with life.

With a loud "crack," countless fissures appeared on the fleshy spheres. As black blood oozed out, they unfolded, revealing their true form.

It looked like a floating island, or perhaps a deformed giant—undeniably a monster.

The giant expanded rapidly, spewing black blood as it grew, linking the ground to the black sun overhead.

Unable to bear the sight, many averted their gaze.

The air filling the forest was the giant's breath.

The overflowing magical energy caused the flesh to rupture, turning into black blood that polluted everything around it.

This wasn't magical energy—it was a visual manifestation of a curse.

Just looking at the black mud sent chills down everyone's spine.

The Servants realized at that moment what homogeneity truly meant. The black blood was the result of failed Servant summonings; just a drop would be enough to assimilate them.

The Masters fared no better. Just looking at the curses caused intense mental pain. Walking through such a thing for even a meter would weaken them, sinking them into the mire.

Could something like this be purified? This question arose in more than one person's mind.

But Shinji and Justeaze had been waiting for this moment.

"Finally, we've drawn you out."

The Great Holy Grail had been polluted by Angra Mainyu's presence. As long as Angra Mainyu remained, even if the Holy Grail were temporarily purified, it would be contaminated again. To solve the problem once and for all, Angra Mainyu had to be removed from the Holy Grail.

And this was exactly what Angra Mainyu himself desired—to manifest in the world.

Shinji had insisted on sacrificing six Servants for this very reason. Only by offering all six could the path to the physical world be fully opened, allowing Angra Mainyu to descend.

Now there was only one task left: face him head-on and defeat him!

"Everyone, attack together! Don't leave a single trace behind!"

Shinji shouted from the sky, leading the charge as he swung the Sword of Love toward the giant's head.

Justeaze followed closely behind, unleashing the Third Magic, which transformed into ropes that tightly bound the giant's limbs.

Seeing this, the others hesitated no longer and unleashed their powers.

Artoria and Altera charged forward side by side, with the Excalibur and the Photon Ray carving deep wounds into the giant's body.

Karna ascended into the sky, the flames of the sun enveloping his divine bow as he pierced through the giant's chest.

Roman and Medea chanted spells, slowing the expansion of the flesh.

Faker and Medusa summoned their mounts, soaring through the air and repeatedly striking the giant's back.

Jack... she specialized in anti-human combat and had no long-range abilities, so she could only cheer from the sidelines.

Lorelei drew her Five-Star Barrage, and five spears of light pinned Angra Mainyu's manifested body to the ground.

Sakura and Bazett inscribed runes, and Rin and Luvia simultaneously unleashed their gemstones.

Illya transformed into a magical girl, while Olga Marie called upon the power of the stars with her Magecraft.

Waver, utilizing Discerning Eye, coordinated the attacks, ensuring that no magical energy was wasted.
