[Night falls, in a dark, desolate cave.]
[Inside the cave, a bonfire burned slowly.
A pale-faced middle-aged Magician stood by the magic circle. In the center of the magic circle lay a golden tool resembling a key.
He stretched out his hand, and a blood-red command spells appeared on the back of his hand. He chanted loudly.
"With silver and iron as the essence, with stone and the great duke of contracts as the foundation, build a wall against the descending wind, close the four gates, emerge from the crown, circulate to the three crossroads of the kingdom."
"Cycle and return, reaching five times."
"Close, close, close, close."
"Here I declare, follow this will, this ritual, then respond!"
"You shall obey the summoning of the Holy Grail!"]
[Misaka Mikoto: "Is that a summoning ritual like in manga, to summon evil monsters?!"]
[Elaina: "It is a summoning circle, but it doesn't seem to be for summoning evil beings, does it?"]
[Mash: "Senpai, that gentleman has command spells on his hand, this is the summoning ritual for Heroic Spirits!"]
[Fujimaru Ritsuka: "Yes, that's right, and judging by the magical energy fluctuations, it seems to be quite an extraordinary existence."]
[Whitebeard: "Kuhahahahaha, I really don't understand anything from other worlds. Can someone explain it? And what does Holy Grail War mean?"]
[Merlin: "Then let me, with my big brother attributes, explain it to everyone~"]
Merlin: "The Holy Grail War is a battle centered around the Holy Grail, its purpose being to fulfill the holder's wish. The Holy Grail is seen by participants as an omnipotent wish-granting machine, capable of satisfying the victor's desires."
Merlin: "In the Holy Grail War, participants summon Heroic Spirits to fight for them. These Heroic Spirits are endowed with modern knowledge to better adapt to the modern world. Participants of the Holy Grail War include Masters and Heroic Spirits."
Akemi Homura: "The Holy Grail... a wish-granting machine? It doesn't sound like a good thing."
Luffy: "Does that mean I can wish for a lifetime of endless meat?! Hahahahahaha!"
Nami: "Idiot! If you're going to wish for something, wish for a lifetime of endless money!"
Okazaki Ushio: "Can... can it really grant anything?"
Meli: "Oh my Looks like a little loli with a wish. Big sister can tell you, theoretically, yes"
Aqua: "There's really such a thing?! Then I wish to become the supreme ruler!"
Satou Kazuma: "As expected of you, the number one iconoclast! Goddess of Stupidity!"
...Nasuverse World
Fourth Holy Grail War Era
Einzbern Family
"The Holy Grail..." A deep glint flashed in Emiya Kiritsugu's eyes.
Once all of this was over, he would definitely obtain the Holy Grail and bring true peace to this world!
...Lostbelt No. 6
"Heh, the Holy Grail? It's merely the dregs of the Age of Gods, yet some still wish to use it to grant wishes. How laughable."
Morgan sneered, as if recalling a certain ahoge figure...
Tohsaka Family
"Another group of mongrels coveting this King's treasures!" The Oldest Fat Tiger's serpentine eyes glowed with dangerous crimson.
His treasures could only be used by him and his friend!
...
"Boom—!"
Mana raged, strong winds swept forth, and after the blinding light dissipated, a Heroic Spirit clad in golden armor, noble and domineering, appeared in the center of the magic circle!
His handsome face was carved like a knife, his golden short hair stood on end, and his crimson serpentine eyes revealed an air of unparalleled arrogance.
Gilgamesh, The Oldest Hero King, sat on a stone chair, looking at the man before him with disdain and arrogance.
"It's done... Hahahahahahaha! Hahahahahahaha!" Seeing that he had truly succeeded in the summoning, the middle-aged Magician covered his face and laughed maniacally.
It's stable, it's stable!!! If it's this one, then this Holy Grail War is within his grasp!!!
"Answer me, are you the arrogant Magician who presumes to seek this King's glory?" The King questioned.
"That's right, I am your Master," the man laughed wildly.
The next instant, the man's arm, bearing the command spells, was severed.
"So you're a clown, then you must let out a more magnificent wail to entertain me," the King rested his chin on his hand, looking utterly bored.
From the darkness, a petite figure emerged. The girl respectfully bowed and knelt.
The middle-aged Magician's palm had been cut off by her.
"I humbly request that the great King grant me permission to appear before your presence."
"Granted. I bestow upon you the honor of an audience with me."
"It is a great honor," the girl placed her hands in front of her, respectfully walking towards Gilgamesh.
"You didn't let that mongrel's blood splatter before me, which is commendable, but you dared to let this unworthy flesh reek in my presence."
"I'd like to hear your excuse," the King narrowed his eyes.
"None," the girl knelt on the ground, "I was presumptuous. I merely felt that dealing with a thief who stole the key to the Gate of Babylon did not warrant the King's personal judgment, so I took matters into my own hands."
"This key?" Gilgamesh snorted, glancing at the summoned key, a flicker of boredom in his eyes, "Boring. Although I ordered it to be made, I felt no need for it, so I tossed it aside."
With that, Gilgamesh threw the pure gold key onto the ground.
The middle-aged Magician tried to pick it up, but was warned by the girl, "Leave now, and I will spare your life."
"Consume all, curse burst forth!" The middle-aged man's expression twisted, his left hand glowing with dark and ominous mana, striking directly at the girl, but the girl showed no panic.
She clapped her hands to the ground, and a towering fire tornado engulfed the man completely!
Moments later, a mummified corpse appeared in his place.
Senju Hashirama: "Hahahahaha! Is that ninjutsu without hand seals? Clapping your hands and summoning whatever you want is indeed convenient."
Tohsaka Rin: "This uncle is terrible. Not only is his mana evil, but his control is also poor. He deserved to die."
Siduri: "To be so disrespectful to the King, such a punishment is deserved!"
Red A: "If this King is summoned, then this Holy Grail War will be interesting."
Smoke Mirror: "Hehe, The Oldest Fat Tiger truly lives up to his reputation."
Kurosaki Ichigo: "Is this King very strong? Where does he rank among Heroic Spirits?"
Merlin: "Roughly, he's top-tier~"
...Chaldea
"Ma... Mash, when we go to the Seventh Singularity, you must remember to show respect to this King!" Fujimaru Ritsuka's face was a little pale.
He clearly had some understanding of this King's temper...
Tohsaka Family
"Heh," Tohsaka Tokiomi revealed a scornful smile, clearly mocking the dead fool.
Brother, facing such a living father, you're still so arrogant. You're truly brave.
Do you think everyone is a loyal subject of the King?
Thinking so, Tokiomi proudly adjusted his tie.
To put it bluntly, he was the King's most favored subject!
