Shirou, who returned from the Fairy Kingdom

At least, it cannot be used when facing the upright Karna.

Seriously, you've really made me suffer, Artoria of this world...

Shirou sighed, but a smile remained on his lips.

The reason—of course—is that he, like Karna, is enjoying this ultimate duel.

Although he felt somewhat sorry for Aika, Shirou was currently immersed in the joy of fighting a formidable opponent.

Oh no...!

This is... my "personal desire"...

Shirou had a sudden realization that things were going badly.

One, two, three, four... five... ugh, forget it! Whatever! Let's go!

"Feel honored, Kshatriya... I, the king, will be your opponent."

Shirou spoke calmly, drawing the Star Sword from the void.

Even if you possess the Infinity Blade, in the end—

The only Noble Phantasm capable of countering the strongest spear is the strongest sword.

"------!"

The Star Sword was not encased in the Wind Sheath; its golden radiance instantly filled the entire space, enough to rival Karna's solar magic.

The moment Karna saw the Star Sword, his magical power surged again, and he prepared to unleash his Thunder Spear.

The pitch-black spear tip seemed like a black hole itself, distorting the surrounding space. Just by being pointed at it, Shirou felt as if his Mystic Eyes had seen death.

Nevertheless, he remained calm and composed, and instead of retreating, he took a step forward.

Karna unleashed his Noble Phantasm before Shirou could.

"Know the mercy of the King of Gods."

"Indra, look at us with new eyes."

"This very blow is what we call extinction... Now, the world will see the sunset."

The jet-black gun body erupted with enormous energy, turning everything around it incandescent.

Then, in that deathly space, a clear female voice echoed—

"Seal Thirteen!"

"Decision start!"

Legend has it that the Holy Sword was originally forged to defend against extraterrestrial enemies and was meant to be wielded to save the world.

In preparation for the arrival of a true enemy, the Holy Sword was somehow imbued with a seal designed in the style of kings and knights.

That is, the thirteen seals that restrict the "true power" of the Holy Sword.

Only when multiple honors and missions can be achieved will the original firepower be unleashed.

The number of resolutions required for complete liberation is seven.

Even if the King of Knights and the Twelve Knights have passed away from this world, this bond will remain in effect forever.

Currently, the Holy Sword has announced a roundtable resolution.

"This battle is a battle against the brave." — Admitted.

"This battle is a battle for survival." — Admitted.

"This battle is a battle for honor." — Admitted.

"This battle is a one-on-one fight." — Admitted.

"This war is not a war that deviates from humanity." — Admitted.

"This battle is not a battle against the elves." — Admitted.

"Gulp... Galahad, you bastard!"

Shirou gripped the hilt of his sword tightly.

The number of resolutions passed was six.

By sending Astolfo away, the "one-on-one duel" constraint was unlocked at the last minute.

Unfortunately, in the end, all their efforts were in vain.

In the end, Shirou still failed to pass Lord Galahad's test of selflessness ("This battle is not a battle mixed with personal desires").

Unable to be fully liberated —

Although it failed to obtain a majority vote, the support of the six Knights of the Round Table still flowed into the Holy Sword, causing it to burst forth with unprecedented brilliance.

The son of the sun god swung down the jet-black thunder spear, and the red-haired holy swordsman raised a bundle of stars above his head.

"Sun, obey death (Vasavi Shakti) ————!!!"

"Excalibur—the sword of valor!!!"

The divine Noble Phantasm, "Sun Wheel, obey death."

The Noble Phantasm for attacking cities is "Excalibur".

The clash between the strongest spear and the strongest sword instantly engulfed everything around them.

Can we win...?

Can't win!

Ah, the power of the God-Slaying Spear is indeed stronger!

The clash between the holy sword and the divine spear lasted only a few seconds before Shirou reached his conclusion.

The Holy Sword, not fully unleashed, could not overcome Karna's Thunder Spear.

As expected of Karna's strongest trump card, which he obtained by sacrificing his golden armor.

Shirou once thought that it was a Noble Phantasm for "anti-god attacks" like "Chaos Blade", but that is not the case.

—It is simply an existence whose firepower is strong enough to annihilate a god in one blow.

The power of "O Sun, submit to death!" is enough to utterly destroy all "single" existence in the world.

Living beings, non-living beings, and even any object, including magical beasts, mythical beasts, divine beasts, humans, shields, armies, cities, barriers, and gods—nothing can withstand it.

That's why it's called an "Anti-God Noble Phantasm," an ultimate spear of light capable of killing even the concept of gods.

Although the Holy Sword's defeat was inevitable, the boy did not panic.

The Holy Sword lost, but Shirou did not.

After two battles, Shirou has discovered Karna's greatest weakness—

His magic consumption is terrifying.

In terms of Servant performance alone, he is undoubtedly a groundbreaking Heroic Spirit who can rival Gilgamesh, but the burden on his Master is dozens of times that of the King of Heroes.

There is simply no magician capable of consuming Karna's magical energy.

This time, thanks to Amakusa Shiro's provision of 60 years' worth of magical resources, he was able to unleash his full power.

On the other hand, although the Holy Sword is inferior to the Thunder Spear, the difference in their power is actually not that great.

At least it's not so big that it could be directly suppressed or collapsed by the other side.

Shirou only needs to maintain the current 40/60 split, and then use the "Heart of Albion" to convert magical energy, continuously supplying it to the Holy Sword—

The solution is to turn this firepower showdown into a protracted battle.

How long can Karna's mana supply sustain him in unleashing his lightning spear?

Ten seconds? Twenty seconds? Thirty seconds?

Shirou felt that freeing up the Holy Sword for even a minute wouldn't be a problem.

I will be the one who wins in the end!

Shirou was absolutely certain of his victory.

He lay dormant, using his magic to heal his skin burned by the aftershocks while continuously channeling dragon magic into the holy sword.

"——————"

The statement that time slowly passes is not entirely accurate.

In that instant, both time and space seemed to lose their meaning.

The five senses become extremely acute.

In a daze, Shirou suddenly remembered something Morgan had once said.

The Earth's surface in pan-human history is not real.

That was a planetary environment modified so that humans could perfectly adapt to it.

A fabric called "Physical Laws" covers the planet's surface, and several anchors, including "The Holy Lance Rungomminiad," are driven into the earth to maintain this thin fabric.

Therefore, the current planetary environment is much more fragile than that of the Age of Gods.

Shirou and Karna were well aware of this as well.

However, what they didn't know was that the "fabric" of this world was even more fragile than that of other parallel worlds.

The reason is very simple.

The divine British Empire, which existed 1,500 years ago, greatly altered the course of human history.

Although the Savior saved the world from the clutches of the Moon King and overturned the established order, the planet and humanity themselves were burdened with a heavy responsibility.

This is also very evident in modern times—

Mystery has declined to its limit, and the development of the magic world has almost come to an end.

The Clock Tower has never produced a genius like Kenneth, nor has the Grand Magician Aozaki Touko—

As a result, even a second-rate figure like Danic was able to obtain the Clock Tower's crown rating through bribery and political maneuvering.

Now, this already fragile world has been torn open by the fierce battle between the heroes of the Age of Gods—the clash of the Holy Sword and the Thunder Spear.

"……what?"

Shirou felt a powerful suction force coming from behind him.

This is similar to an airplane flying at high altitude being suddenly opened by a passenger.

A huge pressure difference was created between the inner side and the surface of the planet, which directly pulled Shirou into it.

……

……

Meanwhile, in Sigishwara.

"————Saber?"

Sajo Aika stood up from the bedside.

Since Shirou entered the Hanging Gardens, she has been unable to monitor his movements through her familiars.

If she had known it would turn out this way, she would have insisted on having Shirou take her along no matter what.

The girl placed her hand on the Seraph Command Seal on her chest, her face showing unease.

She had a gut feeling that something bad had happened to her beloved knight.

The girl was unaware that Shirou had already disappeared from this world.

……

……

"...Wake up...wake up..."

In his severely blurred consciousness, Shirou heard a very familiar voice calling his name.

"……wake up……"

Please have mercy on me, Sakura...
