Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 183 The Real Caster

Fuyuki City, Holy Church.

The chapel was deserted in the dead of night, with only the candles on the altar flickering in the wind, casting long, ghostly shadows of the pews.

Supervisor Kotomine Riki stood in front of the monitoring console in the underground secret room, his brows furrowed into a deep frown.

The red wine in his hand had long since lost its fragrance, but he was oblivious, staring intently at the enormous crystal ball in front of him.

He had been sitting at this table for a whole day.

"The Avenger...and the Berserker who failed to activate the pedestal...two pseudo-Servants..."

'

Li was muttering to herself, her fingers tapping unconsciously on the table.

From the very beginning, this Holy Grail War had an eerie sense of being out of control.

According to the mechanism of this ritual, when an anomaly that does not belong to the regular seven classes appears, it often indicates that the Greater Grail system itself has suffered some kind of irreversible damage or mutation.

"We must inform Tokiomi as soon as possible..."

Just as Li Zheng was about to turn around to get the magical artifact for delivering the message, the crystal ball behind him, which had been silent all along, suddenly burst out with a piercing buzzing sound.

Buzz—!

The sound was so sharp, like a sharp fingernail scraping across a blackboard, that it sent a throbbing pain through Li Zheng's temples.

He turned around abruptly, his pupils instantly contracting.

The murky surface of the crystal ball became crystal clear at that moment.

On the star chart representing the seven classes, the Caster pedestal, which had dimmed due to the failed summoning, suddenly burst forth with a dazzling purple light!

"This...how is this possible?!"

Li Zheng exclaimed, "Didn't the spellcaster's summoning fail? That Avenger occupied the summoning channel; the spellcaster's seat should be ruined by now!"

Li was trembling as she adjusted the crystal ball's perspective. The sensation pierced through the church dome, through the clouds of Fuyuki City, rising ever higher...

Finally, it stopped at the stratosphere, 20,000 meters above Fuyuki City.

"In the sky...?"

Li slumped into a chair, the wine glass slipping from her hand and shattering into pieces.

"Summoning from that location? Who could possibly generate such a massive magical reaction...?"

'

20,000 meters above Fuyuki City.

This is a forbidden zone for life.

The thin oxygen, the sub-zero temperatures, and the violent air currents that could tear flesh apart constitute an absolute realm that mortals cannot reach.

At this moment, a huge, streamlined airship is silently hovering in this deathly silent night sky.

It is 200 meters long, completely black, and has no markings, like a giant deep-sea whale lurking in the sea of ​​clouds.

The airship's surface was covered with some kind of optical camouflage pattern, allowing it to blend perfectly into the night, making it impossible for even the Self-Defense Forces' advanced radar to detect its presence.

The luxurious observation deck atop the airship.

The gravity here is perfectly controlled by magic, the temperature is pleasant, and the air is fresh, as if it exists in a different dimension from the harsh environment outside.

A petite figure was leaning over the huge floor-to-ceiling window, looking down at Fuyuki City, which looked as tiny as a star chart.

She was a girl who looked only fourteen or fifteen years old.

She was wearing a black and white Lolita dress with a gothic style, with layers of intricate lace.

Her long, smooth, light purple hair was casually draped behind her, with slightly curled ends.

She was really small, only 1.5 meters tall, and so light that she seemed like she could be blown away by a gust of wind.

But in those purple eyes flowed a madness and cunning that was completely at odds with his appearance, a cunning that had been tempered over hundreds of years.

"Wow, this is really going to be interesting. It would be a shame not to get involved."

She let out a silvery laugh, sweet yet cruel.

The girl's name is François Preiratti.

In secular history, he was a black magician who colluded with the famous "Bluebeard" Marshal Gilles de Rais and was one of the driving forces behind the tragedy of Joan of Arc.

What few people know is that this infamous alchemist survived into the modern era by frequently changing bodies and creating illusions, as well as due to certain special bloodline influences.

And this beautiful young girl's body is just a small episode in the countless pranks she's played throughout her long life.

"Imagination is beyond imagination! Imagination is beyond imagination~!!"

"A heroic spirit that doesn't belong to this world has appeared~"

"This is so interesting, so very interesting!"

Prellati turned around, her bare feet stepping on the expensive Persian carpet, and twirled around happily like a child.

She casually grabbed a handful of colorful candies from thin air and stuffed them into her mouth, crunching them loudly.

"That Avenger... hehe, he has a smell that makes me want to vomit and laugh at the same time."

"It's similar to that Avenger from last time, but also like something else... It squeezed out the places that were originally ours, haha."

Prellati licked his lips, his eyes gleaming with a brilliant purple light.

"Since that serial killer failed, why don't I take over this vacant position?"

She walked to the center of the observation deck.

There weren't any complicated magic circles drawn there, because for a magician of her caliber, form was irrelevant.

She even used herself as a medium, allowing magical circuits to continuously illuminate her body.

"Come on, come on, real Caster!"

Prellati raised his arms high, without chanting any lengthy incantations, but simply extended the most sincere invitation to the void.

"The stage below is set up, with vengeful spirits, crazed knights, an arrogant king, and the adorable Ato-chan..."

"What a pity, if Saber were replaced by that sow, I could have tormented her to my heart's content~"

"Never mind, how can such a lively party be complete without us?"

"Let us utterly humiliate the Holy Grail!"

"Come out, François Preiratti!"

boom-!!!

The space inside the airship twisted strangely in that instant.

Countless slippery, sea-smelling tentacles flashed through the air.

A sense of dread, from the deep sea and from the ancient past, instantly filled the entire observation deck.

Right in front of the young girl Prellati, the air shattered like a mirror.

A pale, slender hand with distinct knuckles reached out from the void and gently grasped Prellati's outstretched hand.

Immediately afterwards, a figure slowly walked out.

He was a young man wearing a magnificent robe and with short, light purple hair.

In his hand, he held an ancient book that exuded a strong smell of blood and an ominous aura.

The book's cover is not leather, but rather some kind of... specially treated human skin.

Touching it, you can almost feel the pain and wails of the person who lived there.

That is the Noble Phantasm - "Luoyan City Teaching Book".

The boy looked almost exactly like the girl Prellati, only younger, more androgynous, and with that pure, wicked smile on his face.

That was the male face of François Preiratti, recorded as a Heroic Spirit.

It is also a real Caster.

"Oh, it's been a long time, or is this our first time meeting?"

The boy tilted his head, looked at the girl version of himself in front of him, and greeted her with a smile.
