Eiji's External Technique: Holy Grail originates from the Type-Moon world.
Legend says the Holy Grail is an omnipotent wish-granting machine capable of fulfilling any desire.
However, like most legends, the Holy Grail is not omnipotent.
In fact, shortly after rumors of the Holy Grail in Fuyuki City surfaced, the Church investigated it.
They subsequently classified it as a fake.
Meaning this Holy Grail is a fraud, so don't be fooled.
Then why is the Holy Grail called an omnipotent wish-granting machine?
Because for most people, the Holy Grail can indeed grant their wishes.
However, the method by which it grants wishes requires you to provide it.
The Holy Grail's method of granting wishes is the Third Magic, soul materialization.
At its core, it's an entity containing the Third Magic and possessing immense magical resources.
Just like Shirou Kotomine, who wished to save all humanity with the Third Magic, the Holy Grail answered his wish.
Animsphere, the founder of Chaldea, also wished for a massive amount of money and succeeded.
But Kiritsugu Emiya could not. The wish he made to the Holy Grail, "World peace, no conflict among humans," was something even he didn't know how to achieve.
Therefore, even if the Holy Grail hadn't been corrupted, Kiritsugu's wish could not have been fulfilled.
But for most people, the Holy Grail is indeed an omnipotent wish-granting machine.
I wish for the Third Magic to materialize a large sum of money for me, and then summon a wife for me.
Is there a problem with that?
There's no problem.
Moreover, if you have any problems you can't solve, you can also have the Holy Grail summon a Servant to help you.
It's just that summoning a Servant consumes an enormous amount of magic, and you might have to save up magic for a long time, like in the Type-Moon story, to use it once.
However, Eiji doesn't have that many ideas right now.
This time, the wish Eiji wants to make to the Holy Grail is very simple.
With the help of the Third Magic, he wants to explore his soul and body to understand the essence of the Ten Shadows Technique.
Where does Jujutsu truly exist?
Initially, Eiji thought it was in the brain, but what about Kenjaku? Sukuna only has fingers, where's his brain?
And then there's Junpei Yoshino, who possesses Cursed Energy and Jujutsu but cannot use Jujutsu due to the structure of his brain.
Furthermore, Sukuna once told Yuji Itadori in the juvenile detention center:
"Even if I die inside you, I still have 18 soul clones outside..."
Based on this, Eiji speculates that the source of Jujutsu might be related to the soul.
Sukuna's Finger is merely a vessel for the soul and Cursed Energy.
The word "soul" in the Third Magic's soul materialization also indicates its mastery in the realm of souls.
If one doesn't understand the soul, how can it be materialized?
Therefore, Eiji decides to make a wish to the Holy Grail, asking it to help him explore his soul.
"Are you ready, Eiji?"
The one speaking is Medea.
She is responsible for the preparations and safety measures for this wish.
"Let's begin, Medea."
A golden cup appeared in Eiji's hand.
Because it's an External Technique, the Holy Grail can also be removed from his body.
The golden cup was placed in the center of Medea's magic circle.
This was a magic circle meticulously prepared by Medea to monitor the Holy Grail's operation and Eiji's condition.
If anything went wrong with either the Holy Grail or Eiji, Medea would intervene immediately.
Eiji lay on the ground, slowly falling into a deep sleep, his consciousness becoming increasingly blurry.
Gradually, Eiji felt a thick, viscous sensation surrounding him.
It was as if he had fallen into a swamp.
Feeling immense resistance as he tried to move his arm, Eiji was filled with confusion.
Soon, Eiji saw his surroundings clearly.
Eiji felt as if he were submerged in a dark, viscous liquid, with resistance similar to seawater with every movement.
The only light source in the entire world was a human-shaped silhouette far above.
"Is that my body?"
Eiji struggled to lift his hand.
As expected, his arm in his line of sight had become ethereal and unreal.
No matter how long he had been sinking, Eiji felt a strange light emanating from below.
It was the same light as the Demon-Slaying Sword radiating positive energy from Mahoraga's hand.
Eiji turned, and a peculiar magic circle appeared in his vision.
Mahoraga stood in the center of the magic circle.
Like a colossal stone statue.
Beneath Mahoraga's feet was a massive pattern of the Eight-Handled Sword.
With Mahoraga at the center, nine lines extended outward from the magic circle.
At the end of each line was a Summoned Spirit.
However, one of the Summoned Spirits had already vanished.
Eiji approached Divine Dog: Black, looking at the foot-jade beneath its paws, and the Dao Fan Jade representing Divine Dog: White beside it.
But the pattern of the Dao Fan Jade was already blurry.
Eiji reached out and touched the indistinct Dao Fan Jade pattern.
He then carefully sensed the magic circle of the Ten Shadows Technique.
With the Holy Grail's blessing, Eiji's soul power grew stronger and stronger, and his perception became keener.
Soon, a wondrous sensation came from the magic circle.
This magic circle seemed to be connected to something on a deeper level.
Eiji spread his arms and lay down at Mahoraga's feet, which was the very center of the Ten Shadows Technique's magic circle.
The Holy Grail's power continuously bolstered Eiji's soul, and gradually, Eiji felt himself sinking into another world.
The light overhead disappeared.
This was a manifestation of Eiji's soul leaving his physical body.
In reality, Medea, who sensed Eiji's soul drifting further away, immediately prepared to recall his soul at any moment.
Eiji felt as if he had taken a nap.
After waking up, he seemed to have traveled again.
Eiji opened his eyes and looked around.
Colorful darkness.
This was Eiji's first reaction.
Eiji's soul drifted in this peculiar world.
Just like the reflections people see on the surface of water, everything here was inverted compared to the real world.
And the light here was black.
Eiji's soul was observing this wondrous world.
Soul vision, different from what the naked eye sees, a shadow world, different from reality.
All of this made Eiji feel incredibly novel.
Soon, Eiji found the thing in this world that had formed a connection with his soul.
It was a massive magic circle, the very source of the Ten Shadows Technique.
This magic circle would leave its projection in the soul of each user of the Ten Shadows Technique, allowing them to wield the power of the shadow spirits.
As he approached the magic circle, Eiji noticed pairs of eyes lighting up in the shadow world.
All these eyes were staring at Eiji, the strange intruder.
"Shadow life?"
Eiji saw creatures resembling Divine Dogs and Orochi among them.
Eiji, while on guard, let his soul drift towards the magic circle.
The magic circle of the Ten Shadows Technique also responded to Eiji.
The shadow creatures retreated, and Eiji placed his hand on the magic circle.
Shadow Cursed Energy flowed from the magic circle into Eiji's soul.
Eiji's soul felt a sensation akin to an itch.
Eiji was delighted to discover that the projection of the Ten Shadows Technique's magic circle within his soul had been repaired.
Divine Dog: White, who had been sunbathing in the courtyard, suddenly pricked up its ears as if sensing something.
Due to its current lack of strength, Divine Dog: White had become the mascot of Jujutsu High, holding a position as a gatekeeper.
The next moment, Divine Dog: White turned into a beam of light and flew into Eiji's soul, leaving only a golden Chess Piece behind.
Gulp, gulp.
"The shadow's moving?"
Medea looked at the shadow beneath Eiji.
Sounds were constantly coming from within the shadow.
"This is bad."
Medea immediately deployed a Barrier, protecting everything inside the room.
BOOM.
Eiji's shadow surged like a flood, overwhelming the entire Barrier.
