Shirou, who returned from the Fairy Kingdom

—Memories of listening to each other's stories on sleepless nights.

—There's also the memory of patting my head, even though I was covered in wounds, I still managed to defeat the beast.

The master and disciple of the past.

The Supreme Sage and the Strongest Warrior.

Father and Son.

Having sealed away all their precious and warm memories, they now clash as opposing heroic spirits.

Achilles, who was killed by an arrow in his lifetime, believed that he could not defeat his teacher who wielded a bow.

Even if we win, it will take a lot of time.

He wanted to decide the winner in a shorter time, in a chilling instant.

So he used his Noble Phantasm.

The Diatrekhon Aster Lonkhe, in short, is a spear for one-on-one combat.

It completely blocks out time and the surrounding environment, creating an arena that will not dissipate until one side is defeated.

In terms of magical principles, it is something that is similar to but not quite a Reality Marble—it does not erode the world, but rather stacks space on top of the original world.

This is the space that Achilles created in the past to settle his score with his arch-enemy Hector.

Hector was Troy's strongest warrior and commander-in-chief. He took over the reins of the army from his father and triggered the Trojan War because his brother Paris took Helen away.

He was both a valiant warrior and a politician whose intentions were beyond the comprehension of even the gods.

Hector laughed and said to Achilles, who was hailed as the strongest warrior, "If I were to fight someone like you who has the protection of a goddess, I would be punished by the heavens," and then ran away.

Therefore—the effect of this Noble Phantasm is not to suppress the enemy, but to create a "space where one-on-one battles can be fought fairly".

Eliminating all "accidental factors" such as divine blessings and luck, the ultimate winner is determined by strength.

Of course, Achilles' immortality (the hero's everlasting flower) was completely ineffective.

After learning of these conditions, Hector accepted the challenge, and Achilles ultimately won by a narrow margin.

Hector accepted the duel with the thought, "In that case, I should have a chance of winning."

What was Chiron thinking?

Achilles is unknown.

In short, now the two of them have abandoned their guns and bows, and with genuine smiles, they are using the most primal weapon of men—fists and feet—to fight each other.

"Ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh ooh!"

"Drink it! Aa ...

The two men roared as they threw punches as if they wanted to shatter the world.

If Atalanta were to see this, she would probably be dumbfounded, and then coldly mutter "idiot."

The "Red" Rider's fist is a one-hit kill, capable of shattering a Servant's soul core with a single blow.

The "Black" archer's fists are ever-changing, a divine-era mixed martial arts technique that allows them to manipulate their opponents at will.

Their martial arts skills were not ranked, but rather differed in direction.

Achilles had an overwhelming advantage in strength and speed, while Chiron was more technically skilled and knew his disciple's fatal weakness.

No one can gain a complete advantage; favorable and unfavorable situations alternate like magic.

However, this balance of power will not last forever.

As the duel intensified, the two grew faster and faster, almost reaching the limits of their Servant bodies, and even approaching their peak performance in life.

Soon, the duel will be decided.

In a single thought, in a single instant.

No matter who it is, if they reveal even the slightest flaw, it will become the fuse that leads to complete defeat.

Achilles throws a punch.

This was actually a feint; a punch with no hidden intent couldn't possibly hit the cunning teacher, however—

The fist struck Chiron squarely in the cheek.

Not only that, Chiron also kicked Achilles away.

As expected of a centaur, even in human form, it possesses such terrifying leg strength.

The "Red" cavalrymen, enduring the pain, rose to their feet and protested to their opponents:

"Teacher, why did that punch hit... huh?"

Achilles saw a sight he could not comprehend.

The "black" archer who had just kicked him away lay in a pool of blood.

Achilles's punch, thrown as a feint, could not possibly have had that kind of power; what wounded Chiron was "something else."

No, it should be said that it refers to "other people"—

A third party interrupted his duel with Chiron and intended to ambush and kill them.

Chiron noticed this and kicked Achilles away.

The "Red" cavalry's mind reacted quickly, but they couldn't understand it.

The space created by "Spear Tip of the Sky Soaring Stars" is an absolute barrier to third parties. How did the enemy manage to get in?

No, there was something even more shocking to Achilles than that.

The weapon that pierced Chiron's body was none other than the stake that had ravaged the Romanian battlefield a few days earlier.

"How can it be……"

Achilles' eyes widened as he roared, "Are you still alive, Lancer?!"

"........."

The "Black" spearmen, who should have been wiped out, were standing there.

He was expressionless, possessing neither the majesty of a king nor the madness of a vampire; he was like a puppet.

However, Achilles could not be mistaken about that overwhelming magic.

What he saw was not an illusion, but the real Vlad III.

"good evening."

Achilles followed the trembling gaze and saw the petite figure of a young girl, as beautiful as a flower.

"Since you two are taking too much time, let me help you out~"

Sajō Aika poked her chin with her finger and said, "Anyway, if we keep fighting, you'll all die together."

Not the magician of the Thousand Trees...

Achilles gritted his teeth: "You are—the Master of the 'Black' Swordsman!?"

Why can she control the "Black" Lancer? Have we been deceived? Did Vlad III actually not return to the Holy Grail?

Countless questions raced through Achilles' mind, but he quickly suppressed these thoughts that would disrupt the battle and drew his spear.

With Chiron's fall, the honorable and fair duel has come to an end.

Achilles surrendered himself to rage and charged toward the girl who had ruined his sacred duel with his teacher.

“You bastard——!!!”

The "Black" spearman stood in front of Ayaka Sajou.

He raised his finger, and dozens of stakes appeared, surrounding Achilles completely.

Having lost his territory, Vlad III's projectiles were far less powerful and numerous than before, and were simply insufficient to stop the "Red" cavalry.

Achilles roared and brandished his spear, knocking away the stakes that were heading his way, and then thrust the spear tip toward Vlad III.

The situation was one-sided.

Regardless of the fact that Vlad III, having lost the advantage of homeland, was inferior to Achilles.

More importantly, lacking divinity, he couldn't even inflict substantial damage on the cavalry.

"The Unfading Flower of the Hero (Andreias Amarantos)".

This is probably the special ability of the world's most famous hero, a blessing bestowed by the goddess Thetis, Achilles' mother.

Except for the heels, all parts of the body will be immune to enemy attacks, meaning they are impervious to blades and spears.

Only Servants with "Divinity" skills of a certain level or higher, or "God-made Armaments," can damage Achilles.

The "Red" cavalry launched a fierce attack on the "Black" spearmen. Although the latter also parried with their spears, they were no match for them. Then, they were sent flying more than ten meters away by a side kick that they had learned from Chiron.

"Unforgivable..."

Achilles glared furiously at Sajou Aika.

Those who defile the sacred duel are unforgivable, even if they are seemingly innocent girls!

The warrior's intuition told him that this girl was not simple, and in order to be sure to kill her, Achilles once again unleashed his Noble Phantasm.

"—Go! Soar across the heavens at the tip of the spear (Diatrekhon Aster Lonkhe)!"

The meteor spear was thrown from the cavalryman's hand, hurtling towards the girl with the force of tearing through the air.

"There's actually such a usage... It's unbelievable that the same word 'liberation' is being used."

Sajō Aika showed an expression of surprise and delight, like a little girl full of curiosity about everything in the world.

The same Noble Phantasm, released with the same true name, produced completely different effects.

Throwing spears—this is another effect of Achilles's meteor spear.

After all, it is a weapon that has made great achievements in mythology, so it naturally has the destructive power commensurate with its level.

Because this gun once killed the Amazon Queen Penthesilea, it cannot be used to create a one-on-one barrier against women. However, this restriction does not apply when used as a flying weapon.

When Achilles throws this spear with all his might, a single blow can erase a Servant of Chiron's caliber from reality.

No matter how terrifying the magician is, there's no way they could survive a direct hit from the Meteor Spear—

A whisper came that made Achilles' heart stop.

“………………Brahma, curse my body (Brahmastra Kundala).”

The radiance of the sun, which arrived along with the liberation of true names, filled the entire space.

The divine spear that shot out brought the power of an "anti-national treasure," instantly vaporizing Achilles' prized spear.

"——————"

After the flames subsided, a new figure landed on the floor.

Those were Achilles' teammates whom he hadn't sensed any magical reaction from just minutes before, and whom he had assumed had died in battle.

"Red Lancer, why are you there! Have you betrayed us too?!"

Achilles was agitated and questioned the hero who had given him alms, but Karna's eyes had long lost their former tolerance and humility.

Like Vlad III, he too became a puppet whose intellect was robbed.

"........."

Achilles' throat was dry.

Following Vlad III and Karna, more shadows appeared behind Ayaka Sajou.

Spartacus, Siegfried, Avisbro.

The cavalry's former comrades or enemies, the heroic spirits who should have returned to their seats, appeared one after another and became the girl's servants.

"What exactly is your purpose...?"

Achilles asked.

The platinum-blonde girl's appearance was the embodiment of innocence and purity, but at this moment, in his eyes, she was a monster more terrifying than anything else.

"Purpose...is that the same as a wish?"

Sajou Aika placed her hand on her slightly heaving chest and gave a bright smile.
