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

In the early morning in Komao Town, the sunlight, as usual, pierced through the thin morning mist, but for some people who had just undergone a reshaping of their values, the sunlight seemed a bit dazzling.

The oppressive pressure that had been so intense it could freeze one's soul receded like a tide as Luo Chen withdrew from the room.

As if granted a pardon, Azazel, the governor of the fallen angels, let out a long sigh of relief, completely disregarding his dignity.

He wiped the cold sweat from his forehead, not daring to take another sip of the coffee on the table, and very tactfully took two steps back.

"Since you have made your decision, we fallen angels will naturally not interfere in this... well, 'game'."

Azazel chuckled twice, glanced at Riser who was sprawled on the ground like a rag doll, and a hint of pity flashed in his eyes.

"I need to go back to headquarters to report on my work, so I won't disturb your morning any longer. Goodbye."

After saying that, as if afraid that Luo Chen would go back on his word, the governor suddenly spread out his twelve black wings, transformed into a black light, smashed through the window, and fled. His speed was so fast that even his afterimage was not visible.

"Runs faster than a rabbit."

Mordred curled his lip and slammed his greatsword into the ground.

"Is this guy really the leader of the three major forces? He's such a coward."

"This isn't called being cowardly; it's called having a clear understanding of the difference in strength."

Scáthach walked to Luo Chen's side, a hint of pleasure gleaming in her crimson eyes.

"Being able to instantly assess the difference in strength between the enemy and ourselves and make a decisive retreat is barely enough to qualify as a competent commander."

Meanwhile, Rias Gremory, standing on the other side, looked extremely awkward and embarrassed.

She looked at Riesel on the ground, then at Luo Chen sitting on the sofa as if nothing had happened, opened her mouth, but didn't know what to say.

Just a dozen minutes ago, she was still agonizing over how to dissolve this damned political marriage, and even prepared to send Issei to his death.

But now, her once arrogant fiancé is lying in front of her like a dead dog, and even the concept of "immortality" has been extinguished by his bare hands.

"What are you still standing there for?"

Luo Chen picked up his teacup, gently blew on the floating tea leaves, and didn't even look at her directly.

"Take him back and relay my words to your brother verbatim. Also, remember to ring the doorbell before entering someone's house next time. Don't let it happen again."

"Yes... I understand."

Rias took a deep breath, forcibly suppressing the turmoil in her heart.

She unleashed the Gremory family's crimson destructive magic, enveloping Riser and the heavily wounded members of their family outside, before bowing deeply to Luo Chen.

"Lord Luo Chen, I will convey your will truthfully."

With a red teleportation array glowing, Lia disappeared completely from the hall, leaving behind the remaining pieces of the game.

With the departure of outsiders, the Fairy Palace finally returned to its internal bustle.

"Dad! You just said you're going to take over that Rating Game thing, is that true?!"

Mordred immediately came over, rubbing his hands excitedly.

"That red-haired woman said that's some kind of arena where demons fight each other? Count me in! I just swatted those birdmen away with one sword strike, but it wasn't enough!"

"Rating Game?"

Artoria (Saber) walked over carrying a plate of freshly baked buttered toast, her ahoge (a single strand of hair sticking up) swaying slightly, and asked in a serious tone.

"Is that some kind of competitive event where you can win high-quality ingredients? If it's to replenish the territory's supplies, then as a knight, I should participate."

All you ever think about is eating.

Jeanne Alter rolled her eyes, but her body betrayed her by squeezing closer to Luo Chen.

"However, since we're going to cause trouble in the Underworld, this kind of menial task should naturally be handled by me, the Dragon Witch. Burning a few demons is much simpler than burning those Demon God Pillars."

Looking at the Servants whose fighting spirit had instantly exploded, Luo Chen smiled helplessly.

"Alright, put away your murderous intent. This is just a game, not an expedition to destroy the world."

He leaned back on the sofa, his fingers tapping lightly on the armrest.

"While the demons of this world are far less mysterious than those of the Age of Gods, their battle system, based on 'chess,' is quite interesting. Kings, queens, chariots, knights, bishops, soldiers… they arrange their minions onto the chessboard to fight each other."

A mischievous glint flashed in Luo Chen's crimson-gold eyes.

"Since they value this childish system so much, then we'll smash their rules to smithereens on their most prized chessboard."

"That sounds like a good pastime."

Morgan le Fay elegantly picked up his teacup, his ruby-like eyes revealing a shrewd wisdom that seemed to see through everything.

"However, Arthur, your provocation just now was tantamount to declaring war on the entire higher echelons of the Underworld. If that Demon King named Sazex isn't a fool, he's probably already considering how to probe your strength in the most 'respectable' way."

The Fairy Queen gave a cold laugh.

"Soon, an 'official' envoy will come knocking."

……

Morgan's prediction came true just two hours later.

The Underworld, the territory of Lucifer, the central hall.

The air here is so oppressive it feels like it could drip water.

"This is utterly absurd!!!"

An extremely angry roar echoed throughout the hall.

The current head of the Phoenix family, Raisel's father, was engulfed in golden flames due to extreme anger.

"A human who appeared out of nowhere! How dare he severely injure my son in the human realm! Even stripping him of his immortality! Lord Sazex! This is a blatant trampling on the seventy-two pure-blooded demons! I request that an army be dispatched immediately to tear that arrogant bastard to pieces!"

In the other seats at the round table, several high-ranking demons echoed the sentiment, and the magic in the hall fluctuated violently due to the crowd's agitation.

However, the current Demon King Lucifer, Sirzechs Lucifer, who sat in the main seat, simply rested his chin on his hand. There was no anger of being offended in his deep eyes, only a chilling calmness.

"quiet."

Sazex uttered only two words.

But along with those two words, a demonic aura, imbued with tangible "destructive power," instantly enveloped the entire hall like a mountain pressing down.

Those high-ranking demons who had just been clamoring for war were suddenly overwhelmed and unable to breathe, and the flames on Phoenix's body were forcibly forced back into his body.

"Lord Phoenix, your son is currently lying in a treatment pod, his sense of time forcibly locked by an extremely high-level magic that even I cannot decipher."

Sazex looked at him, his voice calm yet exuding absolute authority.

"Do you think that was just a normal 'severe blow'?"

"You've all heard the information Ria brought back. She stripped the God-Slaying Gear from its sheer size with her bare hands, and a single glance sent the Crimson Dragon Emperor's soul into shock. Her subordinates can easily annihilate even mid-level Fallen Angels."

Sazex stood up, walked to the huge floor-to-ceiling window, and looked down at the blood-red sky of the underworld.

"Ladies and gentlemen, we are not facing some arrogant human magician."

"But rather, it is something capable of erasing the entire underworld from the map at any time—'out of the box'."

The main hall was deathly silent.

They may be arrogant, but they are not stupid. The Demon King's implication was clear: they couldn't win, they simply couldn't win.

"But Lord Sir Zekes, he has openly taken over Lady Rias's Rating Game. If we back down at a time like this, what will become of our demonic authority?"

Another head of the family asked cautiously.

"If he wants to play, then we'll play with him."

Sazex turned around, a wise glint in his eyes.

"Since he offered to replace Rias in the game, this is actually an opportunity. An opportunity to observe their strength up close, 'within the rules.'"

"This ordinary marriage arrangement will be upgraded to a 'special demonstration battle' of the highest caliber in the Underworld. All Demon Kings and high-ranking nobles will be present as spectators."

"If he truly possesses that incredible power, then we must treat him with the highest level of courtesy. If he's just bluffing..."

Sazex's eyes turned cold.

"Then, on the chessboard, give him the punishment he deserves."

He turned to look at the silver-haired maid who had been standing quietly beside him.

The silver-haired Annihilation Princess known as the "Strongest Queen"—Greefia Lucifers.

"Greefia."

"Yes, Lord Demon King."

"You must personally go to Komao Town and deliver this invitation to the 'Special Demonstration Battle' to Lord Luo Chen."

Sazex's tone carried a rare hint of seriousness.

"Remember, maintain a humble attitude. Treat him as an equal to us... no, as a 'distinguished guest' who is above us. Absolutely do not do anything to provoke him."

"I understand, Demon Lord."

Gurefia slightly lifted her skirt to curtsy, her stunningly beautiful yet expressionless face remaining completely calm.

But deep down, she felt a strong curiosity about the man who made Sazex so wary.

……

Two o'clock in the afternoon.

Behind the town of Koma, the fairy left the palace.

Gurefia walked through the seemingly ordinary but actually terrifying forest.

As a member of Lucifer's retinue, she has an extremely keen sense of magic.

From the moment she stepped onto the mountain, she discovered that the spatial structure had been completely rewritten.

The energy flowing in the air was not ordinary magic, but a kind of "star ether" filled with the aura of the divine era and even faintly exuding the oppressive feeling of higher-dimensional laws.

"This density of magic... even the deepest ley lines of the underworld pale in comparison. Is this truly a barrier that humans could create?"

She calmed her breathing, walked to the heavy mahogany carved door, and was about to ring the doorbell according to aristocratic etiquette.

Click.

The door seemed to have a life of its own, sliding open automatically inwards.

Immediately afterwards, a voice full of energy, even extremely lively, came from within:

"Woof! Welcome! Are you delivering a package? Has the top-of-the-line kitchenware I ordered from that website called 'Amazon' arrived yet?!"

Wearing a pink maid outfit and sporting a pair of fluffy fox ears, Tamamo Cat excitedly poked half her body out, holding a bunch of dripping green onions in her hand.

Gurefia: "..."

This most powerful maid in the underworld, known for her rigor and ruthlessness, fell into an unusual silence the moment she saw Tamamo Neko.

A fox spirit? And wearing such a strangely modified maid outfit?

Most importantly, the madness emanating from this fox-eared girl, who looked like a mascot, actually made even the "Queen" feel a sense of instinctive danger!

"Um... I am a messenger from the underworld, Grayfia Luciferus."

Gurefia quickly adjusted her mindset and maintained perfect manners.

"I have come to request an audience with Lord Luo Chen on the orders of Lord Sazex."

"Oh, you're looking for your master?"

Tamamo-neko took a bite of the green onion in its hand, then flicked its tail in disappointment.

"Come in. Master is watching that 'TV' box in the living room. Remember to change your shoes, or Master Morgan will be angry, woof!"

Glefia changed into slippers as instructed and followed Tamamo Cat into the hall.

However, when she actually stepped into the living room known as the "Fairy's Palace," her proud psychological defenses finally began to crack.

The living room is ridiculously large, with sunlight streaming in through the stained glass dome.

In the center of the huge leather sofa, a man named Luo Chen was leaning back lazily, holding a remote control in his hand.

And beside him...

On the left, a stunningly beautiful woman (Morgan) with long silver hair and wearing a black silk dress leaned on his shoulder, flipping through an ancient magic book.

When Gurefia walked in, the woman merely raised her eyelids slightly.

Just that fleeting glance.

boom!

Gurefia felt her mind go blank, as if a towering glacier had pressed down on her soul.

The indescribable pressure from the superior made her legs go weak, and she almost knelt down.

"What...what kind of monster is this..."

On the right, a girl with pinkish-purple cross-shaped eyes (Tiamat) was lying on Luo Chen's lap, happily munching on a strawberry cake bigger than her face, making cute "Aaa~" sounds.

But that petite body contained a primordial life force powerful enough to instantly evaporate the entire underworld.

Meanwhile, on a carpet not far away, two blonde, blue-eyed women (Saber and the Lion King) are having an extremely serious "round table negotiation" over the last piece of matcha pudding.

Not far away by the bar, a purple-haired woman (Scáthach) was wiping her magic spear. The deathly aura emanating from her was so palpable that Grayfia had no doubt that the woman could pierce her heart with a single shot.

"Gurgle..."

Gurefia, who was known as an ice queen, swallowed hard.

Lord Sazex... do you know what kind of paradise you sent me to?

Any one of these characters could easily defeat all three factions, right?!

"A messenger from the underworld?"

Luo Chen pressed the mute button on the TV remote and turned his gaze to the silver-haired maid standing at the door, her body slightly stiff.

His deep, crimson-gold vertical pupils scanned Gurefia from head to toe in her impeccably Victorian-style maid outfit and her curvaceous, alluring figure, and a hint of amusement crept onto his lips.

"Sazex certainly knows how to pick people. Compared to that idiot with chicken wings from yesterday, you're much more pleasing to the eye."

Luo Chen pointed to the empty sofa opposite him.

"Sit down. Since you're here to deliver a challenge, there's no need to be so formal."

"No, you misunderstand."

Gurefia took a deep breath, and despite the terrifying gazes around her that could kill, she forced herself to remain calm as she walked to the coffee table.

She did not sit down, but instead very respectfully took out a black letter sealed with gold-embossed sealing wax from her bosom and handed it over with both hands.

"This is not a challenge. This is an invitation to a 'special demonstration battle' to take over Rias-sama's Rating Game, drafted personally by Lord Sirzechs."

"A battle to showcase exceptional cases?"

Luo Chen took the letter but didn't even open it to look at it; he simply tossed it onto the coffee table.

"So, your demon king not only agreed to my takeover, but also plans to make a big fuss and, incidentally, probe my strength in front of the entire Underworld?"

"You've got some nerve."

"The Demon King meant no offense."

Gurefia lowered her head slightly, her tone sincere.

"However, your power is far too extraordinary. The Underworld needs a reason that can convince all the nobles. If you can demonstrate matching strength in this game, then from now on, the Underworld will grant you the highest level of courtesy and convenience in all your actions in the human realm."

"Easier said than done."

Jeanne Alter appeared out of nowhere, arms crossed, and sneered.

"To put it bluntly, they just want to see us fail. If we lose, I bet your 'courtesy' will turn into an ambush, right?"

"That's impossible."

Luo Chen smiled.

He stood up, his tall and imposing figure instantly casting a shadow over Gurefia.

He leaned down slightly, looking at the maid who was trying her best to maintain perfect composure even in fear, his voice deep and domineering.

"Go back and tell Sazex."

"I'll take this game."

"Since he wants to see a show, I'll give him a visual feast he'll never forget."

Luo Chen turned around and glanced at the women on the sofa.

"The rules are based on the Demon Piece, right?"

There are sixteen seats in total.

"But I don't need that many people."

Luo Chen held up three fingers, and under Gurefia's shocked gaze, he made this arrogant declaration that would be recorded in the annals of the underworld.

"On my side, I'm only sending three people."

"Whether the opposing side is the entire Phoenix family, or your so-called high-ranking demons or demon king's retinue."

"You can send as many people as you want."

"If anyone can force my three subordinates to retreat even half a step on this chessboard..."

Even if I lose.

Upon hearing this, the hall fell into absolute silence.

Gurefia's beautiful eyes widened instantly as she stared at Luo Chen in disbelief.

Three people?! Going to challenge an entire elite demon familiar?

This isn't just arrogance; it's downright contempt for the rules of the Underworld ranking game!

"What? Do you think I'm being arrogant?"

Luo Chen seemed to see through her thoughts. He chuckled and pointed to Scáthach, Morgan, and Saber sitting on the sofa.

"You can go back and report the truth."

"I, Luo Chen, only play games where the outcome is a complete stomp."

"If everyone has to be involved in this kind of childish game..."

In Luo Chen's crimson-gold vertical pupils, an absolute arrogance belonging to the strongest ignited.

"Then where am I supposed to put my reputation as the 'King of Stars'?"
