Shirou, who returned from the Fairy Kingdom

Although it is only temporary, it can grant the master power surpassing that of demon kings and gods.

The "Crimson Dragon Emperor's Gauntlets" double the power of their wielder every ten seconds.

Even if the initial power is only one, as long as it is doubled every ten seconds, the final power is extremely terrifying.

Originally, Shirou could only project and use weapons such as "swords" and "blades" in actual combat; he couldn't project armor.

However, the "Red Dragon Emperor's Gauntlets" are a slightly special case—

　A certain sword is hidden inside the Dragon Gauntlet.

That's why Shirow was able to complete the projection.

"Boost!"

As time passed, Shirou's left arm, covered in ochre-red gauntlets, began to unleash power.

"Boost!!"

The Sacred gear continuously emits voice messages.

Each low growl causes the dragon's power to flow into Shirou's body.

“…………Huh?”

Bawanshi's forehead was covered in cold sweat.

"Wait...that's..."

She stared intently at Shirou's left arm, a sharp pain shooting through her head—the memories lost due to the failed summoning were returning.

Meanwhile, Black Saber noticed something amiss; Shirou's magical energy was increasing at an unimaginable speed.

"—Excalibur Morgan!"

She launched an attack decisively, unleashing her Noble Phantasm once again without hesitation.

The pillar of fire formed by the reversed aurora swept straight across.

But Shirou was prepared.

"Time alter square acceleration!"

The explosive pain made Shirou's consciousness boil. He swallowed the blood gushing from his throat, stomped his feet on the ground, and leaped backward.

The boy flipped in mid-air, escaping the range of the light cannon while using his willpower to continuously extract power from the Crimson Dragon Gauntlets.

Black Saber was surprised that Shirou could increase his speed; this was the first time she had ever seen someone dodge the released Holy Sword.

"Boost!!!"

"Boost!!!!"

Shirou's power then doubled twice, the power surging from his gauntlet coursing through his body.

The increase in ability is not without limit; it also depends on the user's tolerance level.

Given Shirou's fragile physique at the age of 8, seven times is roughly the limit.

With a final "Boost!!", Shirou's charge was complete.

"Explosion!!"

This sound implies the meaning of stopping the force multiplication, and it refers to a braking device.

Once he stops increasing his power, Shirou can fight for a period of time while still in a state of increased power.

The duration of use depends on the actions taken during that period.

The more active and aggressive the activity, the shorter the time.

Shirou's stamina also plays a role.

If you are fatigued, the usage time will be shorter.

Therefore, one of the secrets to successfully using this sacred gear is that Shirou must not get injured.

During the multiplication period, the power will certainly increase, but compared to when the increase is stopped and the power is maintained, the power of the Sacred Gear will be less stable, and if you act recklessly, there is a risk that your physical strength will return to its original state.

Only when one is uninjured and has sufficient magic power and physical strength can the Crimson Dragon Emperor's power be fully unleashed.

Therefore, the correct way to use the gauntlet is to first charge up to a satisfactory level, then stop multiplying the power, and finally engage in combat.

Back in the Fairy Kingdom, Shirou learned this set of lessons after suffering countless setbacks.

During the God Extinction Tool's multiplication phase, one should not act recklessly; one must either flee or hide.

This would have been very difficult for Shirou in the past, but now he has "Time Control".

In his desperate escape at four times the speed, he repeatedly dodged the saturation attack of the light cannon unleashed by Black Saber.

The moment he finished charging up, Shirou immediately released "Time Control".

This magic trick is useful, but it puts too much strain on the body.

Shirou adjusted his breathing as he faced the girl clad in black armor.

He is now, like Artoria, a red dragon with human form.

"I'll play along to the end...Knight King."

Shirou raised his left arm, which had transformed into a dragon, and pointed his sharp, crimson claws directly at the cold, handsome face of the black-clad swordsman.

"—Come on! Your favorite firepower showdown!!"

-----------

Volume 1, Chapter 113: Do you know the name Bavanshi?

Shirou's presence was completely different from before.

A powerful surge of energy rapidly gathered in his left hand, like a vortex.

The magic was forcibly compressed to its extreme, so much so that one could even see the dense and intense color directly through the naked eye.

"That is……"

Black Saber stared unmoved at the boy, feeling the dragon's magic, so different from her own, against her skin.

The twilight-colored magic did not originate from the "Red Dragon Emperor's Gauntlets (Boosted Gear)," but rather was a fantastical color formed by Shirou refining his own magic to its extreme.

"So that's why you're called Arthur... another 'Dragon of Twilight' from Britain."

Then, she sheathed the black magic sword at her waist, assumed a stance to unleash her Noble Phantasm, and calmly announced.

"A firepower showdown, huh... okay."

The Reversal Holy Sword unleashed a destructive aurora once more.

The crimson gauntlets were enveloped in twilight-colored magical energy.

"Kneel before me, Shirou! The Oath (Excalibur) —"

"Wake up, Saber! Dragon—"

The biggest burst of magic tonight.

The darkness and twilight that shattered the heavens and earth carried the roar of two dragons that surpassed human intelligence.

Two tyrants who once ruled Britain—

The girl, wielding the king's might, unleashed a jet-black holy sword, while the boy raised the dragon's claw and fired a twilight magic bullet.

"—The Sword of Victory (Morgan)!!!"

"————Shoot!!!"

A direct clash with the dragon's breath.

Two enormous energies collided and remained locked in a stalemate, creating a raging storm in space.

This shock shook the fictional landscape created by the Grand Illusionist (Merlin), causing a strong spacetime tremor within the false Unlimited Blade Works.

"This is not good..."

Ms. Avalon frowned slightly.

Even while maintaining his spirit form, it was clear that Shirou was at a disadvantage in his Noble Phantasm duel with Saber.

Even though Shirou's power was increased fivefold for a moment by using the Dragon Gauntlet, the magic cannonballs he fired still couldn't reach the black swordsman.

Conversely, Black Saber's Aurora Pillars gradually eroded Shirou's attacks.

Saber is indeed very strong...

Shirou sighed inwardly.

Saber, corrupted and empowered by the Holy Grail, is a Heroic Spirit who has perfected the fighting style of unleashing Noble Phantasms to the extreme.

If it were simply a battle of Noble Phantasms, even Gilgamesh, the King of Heroes known for his strongest firepower, wouldn't be able to gain an advantage against her.

but……

I was lying when I said I wanted to have a firefight with you! How could I possibly give up my advantages!

I must win! But in my own way—

"Time alter Hexagon accel!"

Shirou roared out an acceleration level that even the inventor of the technique, the Heroic Spirit Emiya, had never reached or dared to attempt.

"Gurgle...!!"

Shirou leaned forward and vomited a mouthful of blood.

Although he had mentally prepared himself for the side effects, the impact that reached every cell in his body still nearly killed him.

With internal time accelerated to this extent, Shirou didn't even have time to think.

This is the world at six times the speed—

How could any human being withstand such side effects? But—

Ms. Avalon once took a million times worse side effects than this for me!

Compared to the suffering she endured, what is the pain I am experiencing now?

Shirou clenched his back teeth.

It was as if he were walking on a planet with a gravity a million times greater than his own; he took his first difficult step.

Shirou's figure disappeared.

The next instant, he appeared in front of Black Saber.

"Blade!!"

The "Crimson Dragon Emperor's Gauntlets" emitted a voice, and at the same time, a gleaming silver blade extended from its front end.

"...fearless resistance."

At the same instant Shirou unleashed his slash, Black Saber drew her sword with one hand to parry.

Even with all his abilities enhanced fivefold, Shirou's strength is still inferior to Black Saber's, so he can wield the sword with just one hand.

However, just as she casually prepared to hit Shirou, a sense of foreboding (intuition) crept into the girl's heart.

Black Saber switched to a two-handed sword-wielding stance without hesitation.

Clang——

The silver sword and the black sword collided, sparks and magical fluctuations erupting, producing a piercing metallic sound.

At the moment of impact, Black Saber realized the truth about the blade extending from Shirou's left arm, took half a step back, and dissipated the force of the stalemate.

She looked surprised: "This is... the Holy Sword of the Dragon Special Forces...?"

Shirou nodded and said, "Ah, it seems to be the holy sword called Ascalon."

Hidden within the red dragon gauntlet, completely assimilated with it, is the renowned sword known as the Dragon Slayer—

"Ascalon" is also the reason why Shirou was able to project the "Red Dragon Emperor's Gauntlets".

Shirou brandished the Dragon Slayer Sword, shifting from a defensive stance to an offensive one.

The holy sword and the demonic sword traced beautiful trajectories, as two different dragon auras clashed continuously in the scorching space.
