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

The Underworld, Lucifer's territory, the Demon King's private meeting room.

The air was so heavy it felt like it was about to freeze.

The current Demon King, Sirzechs Lucifer, sat at the head of the long table, his eyes, which always carried a gentle smile, now as deep as a bottomless abyss.

Opposite him stood Asmodeus, the Demon Lord Falbion, who also had a furrowed brow, and Beelzebub, the Demon Lord Achuka.

Directly in front of the three demon kings, the silver-haired maid Grefia was reporting in an extremely calm tone what she had seen and heard in the "Fairy Palace" in the human world.

"...That's the situation."

Gurefia lowered her head slightly. Even after returning to the underworld, a slight, uncontrollable tremor remained in the fingertips holding the tray.

"Lord Luo Chen accepted the invitation to the special demonstration battle, but made it clear that he would only send three subordinates to fight. He also declared that if Riesel Phoenix's retinue could force them back even half a step, we would consider it a victory."

"Arrogant! Utterly arrogant!"

Farbian slammed his fist on the table. As the highest-ranking military officer, he had the most fiery temper.

"Although Riser has a terrible personality, his entire elite retinue from the Rating Game, combined with his phoenix bloodline, means even a high-level demon wouldn't dare claim they could take on sixteen opponents at once! Does that human named Luo Chen really think he's invincible just because he killed a few fallen angels?!"

"He is not human."

Achuka pushed up his glasses. This top technology developer and brains of the underworld was pale at the moment, with dozens of magic spells floating in front of him, flashing warning red lights.

"Judging from the trace of magic that Grefia brought back, that energy structure does not belong to any mythological system in our universe. Its density, mass, and even its underlying logic all exhibit a domineering nature that is 'above all laws'."

Achuka raised his head and looked at Sazex, his voice hoarse.

"If we were to force a numerical measurement... even the magic power that overflows from his breath would be enough to shatter the entire alternate dimension chessboard of the ranking game."

"That's why I had Gurefia test me with the highest level of etiquette."

Sazex let out a long sigh and rubbed his throbbing temples.

"Three people...that's fine too."

"Notify the Phoenix family and tell them to unleash their most powerful abilities. This match will be broadcast live to the highest levels of the Underworld. We need to use Rassel's eyes to see clearly just how incomprehensible the power of this 'King of Another World' who has descended upon Kuoh Town truly is."

……

three days later.

In the human world, in Kooh Town, the former site of Kooh Academy (now half of it is covered by the Fairy Departure Palace's barrier).

As a strange purple ripple spread across the sky, an alternate dimension, independent of the real world, was forcibly extracted by the technicians of the underworld.

That was a battlefield specifically built for this "Special Demonstration Battle," with a terrain that was a one-to-one replica of Kooh Academy.

At the highest point of the alternate dimension, the VIP floating boxes that were originally reserved for the high-ranking members of the underworld to watch the battle now appeared unusually crowded and had a peculiar style.

"Woof! What a lousy chair! It's not soft at all!"

While complaining, Tamamo Cat pulled out a luxurious bed covered in velvet from the system space and placed it directly in the center of the private room.

"Aaaaaa~"

Larva climbed onto the bed without hesitation, grabbed a bucket of popcorn, and lay down in the most comfortable position.

Her pinkish-purple, cross-shaped eyes stared curiously at the large screen below, as if she were watching a holographic movie.

Ishtar (the goddess of Venus) looked at the underworld decorations in the private room with disdain, and with a wave of her hand, golden magic instantly transformed all the tapestries printed with demon crests into glittering gold ornaments.

"How could such a shabby place be worthy of Luo Chen's status? It really lowers this goddess's taste."

Luo Chen sat leisurely in the center of the large bed, holding a glass of red wine in his hand.

To his right sat Sister Elsa, her face flushed but still trying to remain calm, while to his left was Jeanne d'Arc Alter, who was being forcibly held in Luo Chen's arms and was sulking because she hadn't been able to start the match.

In a corner of the private room, Rias Gremory and her retinue (Akino, Kiba, and Koneko) huddled together, trembling as they watched the group of "gods" who treated the Underworld's highest-level viewing room like their own living room.

"Mr. Luo Chen... are the three of them really alright?"

Rias watched the three figures that had landed on the school playground on the screen, her palms sweating with nervousness.

"Riser's familiars coordinate very well, especially his queen, Eubelina, whose firepower coverage is extremely strong. Moreover, Riser himself is a phoenix; in the game, as long as his spirit core isn't completely destroyed..."

"Shhh."

Luo Chen raised an index finger and placed it to his lips, a wild and arrogant smile playing on his lips.

"Rias, don't spoil the plot when you're watching the show."

"Furthermore, you know nothing about their 'power'."

……

Below the battlefield, at the Kooh Academy playground.

Riesel Phoenix, dressed in a gorgeous dark red gown with fiery wings spread behind her, looked down at the three women standing in the center of the playground.

Around him, fifteen female attendants with different appearances and hot figures had already formed a battle formation, and various colorful magical halos lit up on their bodies.

"Hahahaha! I thought that arrogant man would personally join the fray, but he actually hid up there and sent three women to their deaths!"

Riesel laughed arrogantly, pointing at the three people opposite him.

"However, considering how exceptionally good-looking you all are, I can give you a chance. Now kneel down and swear allegiance to me, become my servants, and I might consider being gentle with you in bed... no, on the battlefield!"

In the center of the playground.

Scáthach wore a deep purple bodysuit and casually twirled a red magic spear in her hand.

She tilted her head slightly, her wine-red eyes seeming to be looking at a pile of rotting garbage.

"Morgan, Saber. Did you hear what this turkey was saying?"

"They are nothing more than dying cries."

Morgan le Fay held up his black magic umbrella without even lifting an eyelid.

She didn't even change into her battle attire today, still wearing that deep purple haute couture trench coat and a pair of exquisite black high heels, as if she were just here for a stroll.

"Insulting the Master is a capital offense."

Although Artoria (Saber) was dressed in modern blue and white casual wear, the moment she grasped the invisible sword with both hands, an extremely chilling kingly sword pressure swept away all the dust within a ten-meter radius.

The tuft of hair on his head was taut and straight, clearly indicating that he was ready for battle.

"Since neither of us wants to waste time talking, let's finish this quickly. Master is waiting for me to go back and give him a massage."

Scáthach's lips curled into a cruel smile. She abruptly stopped her magic spear, the tip pointing at the array of demons ahead.

"One minute."

"What?" Riesel was taken aback.

"I'm telling you, dealing with you bunch of trash will only take a minute."

As soon as Scáthach finished speaking, her figure vanished from the spot like a purple lightning bolt!

[Shrinking the Earth]!

"Fast! Enemy attack! Knight, intercept! Rook, prepare for defense!"

Queen Yubeluna of Riesel was greatly alarmed and immediately issued an order.

Two demon knights wielding twin swords rushed forward like shadows, attempting to block Scáthach's path.

"Too slow. Not only is it slow, but even the way it swings its sword is full of flaws."

Scáthach's voice rang in the ears of the two demon knights like a ghost.

puff!puff!

No one even saw how she drew the gun.

Two red spear beams, like venomous snakes spitting their tongues, pierced the hearts of the two demon knights with pinpoint accuracy!

[Primordial Runes - Concept of Death] are attached to it.

Before the two demons could even scream, their bodies turned to ashes in an instant, triggering the game's protection mechanism and forcibly teleporting them off the battlefield.

"Kara! Sheren!"

Riesel's eyes widened. Less than three seconds into the battle, his two main melee fighters had been instantly killed?!

"Open fire! Blast her to smithereens!"

"Boom boom boom—!"

Several bishops and Eubelina raised their staffs simultaneously, unleashing a torrent of flames and lightning magic upon Scáthach like a violent storm.

However, faced with this barrage of firepower that could level half the playground, a petite yet unshakeable figure appeared like a blue-white meteor in front of Scáthach.

"Your opponent is me, the Magician."

Artoria raised her sword with both hands, facing the barrage of magical attacks, without even considering dodging.

[Magic Resistance: A]

Powered by Luo Chen's [Infinite Ether Furnace Core], Saber's magic resistance even broke through class restrictions, reaching a terrifying level that allowed her to disregard grand magic.

The flames and lightning struck Artoria as if a gentle breeze were brushing against rocks; they didn't even scorch a corner of her clothing before dissipating into harmless specks of light.

"This...this is impossible! Even a high-level demon couldn't withstand my explosive magic!"

Fear finally showed in Yubeluna's eyes.

"Magic? No, what you're doing is just playing with fire."

Artoria's eyes were cold.

She took a step forward, and the [Wind King Barrier] in her hand instantly dissipated.

Dazzling golden starlight converged on the blade.

She didn't reveal her true name, but merely compressed a high concentration of magic power onto the blade of her sword, and mercilessly unleashed a sweeping attack on the group of demon servants in front of her who were already terrified!

"—Drink it!!!"

A golden sword aura, hundreds of meters long, like a crescent moon, hurtled out along the ground!

Wherever the sword energy passed, whether it was the hard ground or the Rook's retinue that tried to raise their shields to defend, everything was neatly cut in two by this absolute physical destructive force, just like cutting tofu!

"Bang bang bang bang—!"

With a series of teleportation beams, two-thirds of Riesel's allied forces were wiped out by this single sword strike!

"No...this is impossible...my family...my invincible formation..."

Raisel hovered in mid-air, looking down at the messy playground, his mind blank.

ten seconds.

Just ten seconds.

His once-proud retinue was now reduced to a lonely queen and two terrified soldiers.

"Bastards! I'll kill you all! I am the immortal Phoenix!"

Riesel completely lost his mind. His body erupted with towering golden flames, and he transformed into a giant firebird, swooping down on the three people below with a frenzied, suicidal momentum!

"The Phoenix?"

Morgan le Fay, who had been standing in the back without making a move, finally slowly raised his eyes.

Her ruby-like eyes gleamed with a cold indifference and disdain that seemed to have seen through the truth.

She lightly tapped the magic umbrella in her hand in the void.

"—In the fairy garden, there is no 'life' that I do not permit."

Om-! ! !

A wave of dark blue magical energy instantly spread out from Morgan as the center.

This is not a physical attack; it is a conceptual interference derived from the combination of Fairy Magic and Simulated Star Chart Avalon!

While diving, Riesel suddenly felt the blood in his body... freeze.

Not only the blood, but also the ever-burning phoenix fire and the concept of "regeneration" engraved deep in the soul were forcibly "covered" and "stripped away" by an extremely domineering high-dimensional law the moment they came into contact with the blue ripples.

"Crunch...crunch..."

The flames on Riesel's body went out instantly.

He was like a plucked, drenched chicken, having lost all lift, plummeting straight down from mid-air.

"Bang!"

He crashed heavily to the ground less than two meters from Morgan's feet, his bones shattered, coughing up mouthfuls of blood, his eyes filled with incomprehensible despair.

"Why... my fire... my immortality..."

"Because I said, you don't deserve it."

Morgan looked down at him, her black high heels mercilessly stomping on Rasel's face, pressing his handsome features deep into the mud.

She didn't even exert any force, but the absolute pressure emanating from the four-digit spirit level prevented Riesel from even screaming. Her eyes rolled back, triggering the near-death protection mechanism, and she was teleported out of the arena as a beam of light.

[Match Ended! Winner: Luo Chen's Family (Substitute Player)!]

The cold, mechanical announcement echoed within the alternate dimension.

The entire process began with Scáthach making her move, and then Morgan knocked Riesel unconscious.

The stopwatch stopped at twenty-seven seconds.

……

Underworld, VIP spectator lobby.

Dead silence.

A deathly stillness, like that of a tomb.

All the high-ranking demons, including Sazex and Achuka, were frozen in place, staring blankly at the three serene and beautiful figures on the screen.

Twenty-seven seconds.

Three women, who revealed no trump cards and did not even unleash the true names of their Noble Phantasms, crushed the elite of the pure-blooded family that the Underworld was so proud of in a completely unreasonable massacre.

Physical immunity? Magical immunity? Concept deprivation?

Any one of these three individuals could single-handedly take on the entire Demon King's camp in the Underworld!

And these were merely three "subordinates" casually assigned by that man named Luo Chen!

"Where...where did this deity come from...?"

Falbion swallowed hard, feeling his calves spinning.

"Sazex... are you sure our previous attitude... was respectful enough?"

Sazex did not speak.

He clenched his fists tightly, his back soaked with cold sweat.

He finally realized how foolish and ridiculous it had been to try to "test" the other person's thoughts.

Before the vastness of the stars and the sea, the dry well of the underworld is not even qualified to cause a ripple.

……

Inside a separate VIP room in a different space.

"boring."

Luo Chen yawned and casually downed the red wine in his glass.

He stroked Jeanne d'Arc Alter's silver hair, who was sitting on his lap, and then glanced at Rias and Aisha, who were completely dumbfounded.

"Alright, the game is over."

Luo Chen stood up, his crimson-gold vertical pupils showing no joy of victory, only a matter-of-fact calm.

He walked to the floor-to-ceiling window of the private room, his gaze seemingly piercing through another dimension, locking onto the direction of the Underworld Demon King's Palace.

He didn't use any communication devices; he simply parted his thin lips, and his voice resounded like thunder deep within the souls of all the high-ranking members of the underworld.

"The performance has ended. I hope you all enjoyed it."

"Now that the rules have been clearly explained, from today onwards, the airspace and territory of Kuoh Town, as well as..."

Luo Chen pointed to Rias and Aisha behind him.

"I'm confiscating all ownership rights to these little girls."

"Who's in favor, and who's opposed?"
