Crossover Anime: I Became Invincible Starting as an Ajin

Yustisa.

Creations created by the Einzbern family.

The path to the origin of the artificial human who realizes the Third Law: the materialization of the soul.

A miracle born out of chance.

The irreplaceable Winter Saintess.

At this moment, in order to fulfill her wish that all humans could achieve immortality by materializing their souls, she used her magic circuits to decompose and magically replace the human universe—that is, the Greater Grail.

Naturally, as the core of the Holy Grail, she sensed that familiar power emerging from the thick darkness.

As the Holy Maiden of Winter, she could naturally sense that the power was the [Third Magic] that her creator, the disciples of the Third Magician, longed for.

The aura of [materialization of the soul].

As she desperately squeezes out the last vestiges of her humanity, she awakens within this corrupted Holy Grail system and perceives the source of this power.

It was discovered that this third law power seemed to have a serious problem.

The other party is like a jumble of odds and ends assembled into the shape of an apple. When you see it, you think it is an apple. It smells like an apple. It tastes like an apple. But you know it is not an apple.

But if something smells like an apple, tastes like an apple, and looks like an apple, can you say that it's not an apple?

This contradictory and awkward feeling was Yustissa's first impression when she saw Wang Bai.

But since it is a Holy Grail system capable of entering the spiritual veins, and it also bears traces of something akin to the Third Law, then the other party must be an exceptionally remarkable mage.

No, should I call him a magician?

Before Yustissa could even think of what to say...

Then we heard this uninvited visitor say, "So big, so white, so bright!"

This caused Yustiza, whose humanity was almost gone, to have a slight fluctuation in his state of mind.

But it was only for a moment. Each time the Holy Grail War began and the long passage of time eroded Justeza's humanity.

There's no need to wait for it to end; Justiza will completely disappear from the Holy Grail.

After this, there will be no more Justisa in the world; only Angolan Mainyu and the Black Grail will remain.

This is probably Yustissa's last time, and also the last chance for the remaining humanity to redeem the world.

"My name is Justisa, and some people also call me the Winter Saintess."

"Who are you? What are you doing here? Where are you going?"

Are we going to start with three philosophical questions?

Could this older sister with magical powers be a philosophy mentor from some fundamentalist natural philosophy school?

Wait, what did she say her name was?

Yustisa?!

Upon hearing this name, Wang Bai immediately knew what kind of world he was in.

Within the Type-Moon universe, specifically the Fate series.

I just don't know if this world is the traditional Fate, or a world that has been altered by a series of changes in settings.

However, what is certain is that the Winter Saintess is still alive and has already activated the Holy Grail system.

So this time the Holy Grail War has definitely begun, and it is very likely that this Holy Grail War is the fourth or fifth Holy Grail War.

The area he is currently in is probably within the spiritual veins under the control of the Tohsaka family.

To find out the specifics, we must leave this place and go out to investigate.

Even if it's just to save his own life, he has to leave this place as soon as possible.

It's important to know that the Holy Grail doesn't only contain the Winter Saintess; there's also Angra Mainyu, who has been corrupted and manifests as black mud and shadows in the Sakura route.

Angolan Manu is considered the representative of evil in Zoroastrian dualism of good and evil.

In historical fact, he was originally an ordinary person. But he was given the title of an evil god.

Those who leave their mark on the world are granted entry into the Throne of Heroes after death.

However, this does not change the fact that Angolan Manuel is not a strong fighter.

Therefore, Angolan Mainyu died soon after the Third Grail War and entered the Lesser Grail.

The corrupted magic of the Holy Grail allows wishes to be fulfilled in extreme and distorted ways.

Wang Bai didn't want that guy to enter his body. If it weren't for the unexpected incident, he wouldn't even want to combine with the product of the Black Grail.

Wait a minute, Wang Bai suddenly noticed something.

If the Winter Saintess were still alive, and the Fifth Holy Grail War were not yet over.

So where did the Black Grail, which was discovered in the demi-human world, come from?

I just don't understand!

"Sir, what's troubling you?"

Yustissa's gentle and calm tone reached Wang Bai's mind.

It was only then that Wang Bai realized he had been too shocked to answer Yustissa's question.

"You might not believe it, but I come from another world. People like us are generally called time travelers. You can just call me Wang Bai."

The Winter Saintess's heart stirred once more. Another world?

In this world, the concept of another world simply refers to the outside of this world.

That means the person in front of you is a pure mage, a miracle worker with magic.

No wonder the other party had the aura of the Third Law.

So, the other party is the new Third Magician?

Perhaps the other party can solve her problem, or rather, solve the problem of the Holy Grail.

"Um, Justisa, do you have any way to get me out of the ley lines? I have something very important to do."

Wang Bai was too embarrassed to voice his needs.

He now feels as if he has broken into someone else's home without permission, been discovered by the homeowner, and is now asking the homeowner if he can find the way out.

Yustissa lowered her eyes, and as the Third Magician, she could naturally see Yustissa's current state.

However, the other party showed no intention of discussing this matter, so the result was clear: the mage was unwilling to help her.

But no matter what choice the mage makes, as an artificial human born from "pursuing the origin," one must show the utmost respect to the other party.

That's not only because of the opponent's immense power, but also because of respect for the generations of magicians, including their own masters, who have been pursuing the origins of magic.

"I will send you away, esteemed mage."

Since the entire spiritual vein is used by the Greater Grail, it is naturally very simple to remove Wang Bai from the spiritual vein.

However, Justisa discovered a new problem.

The mage before me seemed to have been summoned by the ritual of the Holy Grail War, but I couldn't detect any aura of the Throne of Heroes on him at all.

Is it possible for a physical body to be summoned?

Aren't all Servants essentially copies of information from the original on the Throne of Heroes and then uses magic to materialize and act upon it?

Something like an avatar.

After death, the spirit returns to the Throne of Heroes, and the spirit itself reads the experiences of this incarnation as if reading a book.

This clearly shows just how special Wang Bai is—is he a heroic spirit or a magician?
