Crossover Anime: Starting by fusing with an old sword and summoning Morgan

In late autumn in Fuyuki City, fallen leaves covered the courtyard of the Fairy Palace.

Several months have passed since that noisy fireworks display.

During this period, the Round Table family had a very "fulfilling" time.

Mordred is addicted to arcade games and has dominated all the arcades in Fuyuki City, earning him the nickname "Rampaging Red and White Knight".

Nero opened a live streaming account online and gained a group of strange fans called "aesthetic fatigue" with her tone-deaf but confident singing voice.

Tamamo Neko transformed the kitchen into a biochemical laboratory, dedicating herself to developing dishes that could make Heroic Spirits glow;

Meanwhile, the Joan of Arc sisters... continued their daily intense rock-paper-scissors contest over the question of "who will sleep with you tonight."

On the sofa in the living room, Luo Chen was resting his head on Morgan's lap, flipping through a magic magazine, and yawning.

"Peace...it's nice, but the bones are rusting."

"What? Bored?" Morgan said casually, peeling grapes for him while watching a soap opera on TV. "If you're really bored, we can go travel to other worlds."

Luo Chen swallowed the grape and was about to say something.

Om-!

Above the coffee table, the Chaldea communicator, which had been dormant for a long time, suddenly lit up.

The red alarm light flashed wildly, accompanied by a piercing electrical hum.

"Um?"

Luo Chen sat up, his eyes instantly turning sharp.

Morgan waved his hand and turned off the TV, his expression slightly cold: "That spineless doctor calling at this time can't be anything good."

The light screen unfolds.

Dr. Roman's face appeared even more haggard than before in the video.

"Mr. Luo, Mr. Luo Chen! Are you there?! Thank goodness the signal is finally connected!"

Dr. Roman's voice was trembling, and he was clutching a cup of coffee that looked like it had been sitting out for ages.

"Something terrible has happened! Something really terrible has happened!"

"Calm down, doctor."

Luo Chen leaned back on the sofa, interlacing his fingers:

"Didn't Ritsuka and Mashu go to repair the singularities? I remember you took care of the third and fourth ones, right?"

"Yes! Those two singularities were dangerous, but thanks to Ritsuka's command, Mash's perseverance, and the fact that I summoned a few reliable Servants, we managed to barely manage."

It's approved...

Dr. Roman wiped the cold sweat from his face and spoke very quickly:

"But this time is different! The Fifth Singularity: The Great War of North American Mythology... This is simply beyond our current capabilities!"

"North America? A mythological war?"

Upon hearing these two words, Artoria, who was wiping her sword nearby, and Mordred, who was playing a game, both looked up at the same time.

"Yes! The United States of America, 1783!"

Dr. Roman pulled up a map, on which the area that should have been part of the United States was now divided into two distinct colors—scarlet and pale.

"This should have been the era of the War of Independence, but history has been completely messed up!"

"The 'Meron' of Celtic mythology... no, it's the Celtic army that has invaded the Americas! They've not only summoned countless Celtic warriors, but they're even mass-producing Servants!"

"The entire North American continent is now divided in two. One side is the United States Army led by President Edison, and the other side is the Celtic Legion led by Queen Maeve and Cu Chulainn (Alter)!"

"Huh? Celtic?"

Morgan slammed the teacup he was holding onto the table.

As the Queen of Britain, she knew these neighbors very well.

"A bunch of barbarians who only know how to bite like wild dogs. How dare they run wild in the New World?"

"It's not just about running wild!"

Dr. Roman was on the verge of tears:

"That Mad King Cú Chulainn... he's a monster! He wields the Holy Grail, possesses not only limitless magical power, but can also forcibly summon and 'go berserk' other Servants to serve him."

"Ritsuka and the others were saved by Scáthach as soon as they landed, and now they're trapped in a crevice of the battlefield, unable to move forward or backward! That Mad King has already begun hunting down all the rebels!"

"Scáthach?"

Luo Chen raised an eyebrow.

The Queen of the Land of Shadows, the Godslayer, the Master with the curse of immortality?

This is a very important person.

"Mr. Luo Chen! I know you're on vacation... but!"

Dr. Roman clasped his hands together and bowed deeply on the other end:

"The opponent's combat power has exceeded Chaldea's analytical limits. If that Mad King continues to expand, the rate at which the entire Human Realm is incinerated will increase several times over!"

"Please... help Ritsuka one more time!"

A brief silence fell over the hall.

"Hmph, Queen of the Celts...Medve?"

Morgan stood up, her black skirt spreading out like the night.

She walked to the window, looked at the falling leaves outside, and a cold, murderous glint flashed in her eyes:

"That legendary slut with a chaotic private life, who'd even wage war for her desires?"

"Arthur".

Morgan turned around and looked at Luo Chen:

"I hate that woman. I hate her so much."

"I won't be able to sleep tonight unless I trample her face under my feet."

"Cú Chulainn is, after all, a renowned Heroic Spirit known as the 'Child of Light'..."

Artoria gripped the invisible sword in her hand, her expression serious.

"If he has been corrupted by the Holy Grail into a beast that only knows how to kill... then as a knight, I have a duty to give him liberation."

"I want to go too! I want to go too!"

Jeanne Alter peeked out from the stairs, her face beaming with excitement:

"I heard there's a war going on there? And a 'mythical war' at that? Sounds way more interesting than staying home with the kids!" (She's been driven a bit crazy lately by Ilya's constant pestering.)

Looking at this room full of "warmongers" with high fighting spirit, Luo Chen couldn't help but laugh.

He stood up, stretched, and the lazy aura around him instantly vanished, replaced by a terrifying dragon's might.

"Since everyone is so interested, there's nothing we can do about it."

Luo Chen walked to the communicator and gave Dr. Roman, whose face was filled with despair, a reassuring smile:

"Doctor, don't look so sad."

"Send me the coordinates."

"Mr. Luo Chen! You agreed?!" Dr. Roman cried tears of joy.

"Perfect timing, we're almost out of food at home."

Luo Chen glanced at the sky outside the window, his crimson-gold vertical pupils reflecting the distant battlefield:

"I've heard that American steaks are good. And..."

"I also want to see just how strong that so-called 'Mad King' really is."

"Everyone, assemble!"

Luo Chen's voice echoed throughout the entire Fairy Palace.

"Target: The Fifth Singularity - The North American Mythological War"

"Mission: Take down those Celtic barbarians who are disrupting order, and that so-called United States..."

Luo Chen's lips curled into a wildly arrogant smile:

"Subdue them all."

Om-!

The familiar golden portal to another dimension burst open once more.

"Let's go, let's teach that new continent a lesson!"

As everyone disappeared through the portal, Dr. Roman on the other end of the communicator finally slumped into his chair and let out a long sigh of relief.

"We're saved..."

"However... I have a feeling that if we let these people go, the North American continent might be dismantled even more completely..."

Leonardo da Vinci chuckled to himself, "Isn't that interesting? Fighting poison with poison is a fine tradition of Chaldea."
