Shirou, who returned from the Fairy Kingdom

Shirou was surprised to find that after the "Crimson Saintess" disappeared, the person who appeared there was not Metatron, but the girl who had lived with him for a month.

"So tired... I want to die."

Metatron (Sloth) ignored Shirou, who was grabbing his shoulder, and slumped his head listlessly.

She was clearly filled with unprecedented power at this moment—

No, it's precisely because of these powers! Possessing power itself is the greatest form of mental exhaustion!

"Shirou, carry me back... let me sit on your shoulders..."

"Ugh! Such a low mood! Why is it glowing... Don't let it infect me!"

"Master!"

Shirou looked in the direction of Leticia's voice and saw a large number of angels surrounding the Hanging Gardens.

The quantity was so great that it covered the night sky.

Archangel Metatron has departed, but the legion of angels she summoned has not disappeared.

Not only that, the situation is even worse than expected. The out-of-control angels have started indiscriminate attacks. If this continues...!

"I will repair the damaged crown to buy myself some time."

Metatron (Sloth) summoned her throne.

Compared to the real one, the throne of sloth is pitifully small, but even so it is the last hope to stop the out-of-control angel legion.

"……Understood."

Shirou nodded as he summoned Senmon's Noble Phantasm.

Against an army of enemies, projectile Noble Phantasms are more effective than the Holy Sword, and Shirou unleashed a four-figure Noble Phantasm in one go.

The angels that had just approached were shot down, but more angels surged in like a white wave, with no possibility of wiping them out.

"...Tsk!"

Have Xiao Mo and the others been fighting this many enemies all this time?

Even with our angels capable of disrupting the central command system and corrupting the enemy, the situation is unlikely to be much better.

More swords appeared behind Shirou and completed the entire process from loading to firing in a fraction of a second.

"Wait... this is too much, Master!"

Leticia rushed over and helped Shirou up, who was about to kneel on one knee.

It was only then that Shirou noticed that the transmission of magic had stopped not long ago.

Now it is Semiramis who provides him with magic.

The cessation of magic transmission means—

Are you all already thinking about this...? No, now is not the time to think about such things.

Shirou shook his head, clearing his mind of distractions.

Since there's no way to supply the demons, let's squeeze every last drop of our own resources.

Take a deep breath.

The surging dragon heart buried deep within his chest even shone through his skin.

Magic, we need more magic!

I should be able to gain even more magic power!

If even the heart of the strongest dragon cannot satisfy him, he can only take the magic power around him for his own use.

This is a practice that completely ignores the nature of life.

The magical energy remaining after thousands of swords shattered floated around Shirou.

And the almost limitless magic left behind by the archangel's appearance.

So now we'll collect these spirit particles and use our own magic circuits to accelerate their operation.

—That is certainly not a skill of the Holy Sword Wielder.

Gather the surrounding magical remnants and recycle them.

If this can be achieved, then it is clearly a "permanent mechanism".

……

……

"Is that..."

Koles Vervigne Yggdomirenia saw it clearly.

As he boarded the plane with the heroic spirits, he gazed at the sky garden above.

As the current head of the Fulvig family, he has an obligation to watch over them until the very end.

Although his legs had been trembling since he boarded the plane, at one moment his fighting ability suddenly stopped.

The boy saw a dazzling sight.

It was like the most basic form of a magic circuit, a torrent of emerald lightning.

"Frankenstein... Is that so? So you were there all along."

Isn't that how it was written on that design drawing?

Berserker's Noble Phantasm has a hidden power that will create a second version of her with a low probability.

...Of course, that's just wishful thinking.

Shirou is not Frankenstein.

However, the girl did entrust her heart to him.

The first hero to treat her kindly upon entering this world received her power and desires from the berserker.

The "Black" Berserker, being a modern-day Heroic Spirit, is considered a weak and powerless being, but—

Created by Dr. Frankenstein with his life's work, she undoubtedly possesses technology ahead of her time.

And now, this power that Frankenstein could not fully unleash has transformed into the flesh and blood of the strongest hero.

Koles felt extremely proud: if she were the savior who wielded the holy sword and the dragon's heart, she would be able to unleash her power to its fullest potential.

Bathed in the dazzling thunder tree that descended from the sky, Shirou became the true "Permanent Machine" and "Infinite Heart".

……

……

"........."

As a flash of green electricity illuminated the dark room, Ayaka Sajou slowly opened her eyes.

----------

Volume 5, Chapter 259: The End of the War, and Then a New Battle Begins?

Legend has it that the saint who mastered the ancient fighting techniques once fought against the Destruction Angel, who led 12,000 angels, and emerged victorious.

But what Laetitia is now facing is a scene of fighting alone against hundreds of thousands of angels.

The girl didn't even blink; she was completely focused on this final battle that would determine the fate of humanity.

Watching the Holy Swordsman fight to the death with the angels.

As a result, even after accepting the divine sword to protect Paradise, she still couldn't help in any way.

They couldn't offer a single word of support.

It's meaningless whatever I do.

The little power she gained from being in sync with the saints and angels told her.

This is a reenactment of mythology, a realm that is not for us, as human beings, to enter.

The Holy Swordsman relentlessly unleashed hundreds and thousands of swords, striking down the approaching angels, only to have even more angels appear.

Due to the intense battle below, Saber is now unable to receive magical support, yet he fights with increasing ferocity, showing no signs of exhaustion even when abusing his magical power.

It would be impossible to do that with just the Heart of the Dragon.

The reason is probably that he has gained new power—

That's right, she was an artificial human created by Amakusa in the past, and the legendary second type of permanent machine was installed on her.

The current Holy Sword Wielder, in the form of a Heroic Spirit, has reached the "Complete Form," which the mad scientist dreamed of but was unable to achieve.

The planet's strongest core and its endless principles gave birth to an unprecedented golden lightning—

The true "permanent mechanism" was thus completed.

Huang Lei was busy running around.

Shirou continued to accelerate.

Even if the heart of the Grand Dragon is combined with the principle of perpetual motion, it still has to face a greater enemy than itself—the entire Kingdom of Heaven, an army of nearly one million angels.

Even if magic power is infinite, a Servant's physical body still has its limits.

Muscle tissue constantly undergoes a process of destruction and repair, and nerves are repeatedly broken and reconnected.

Ignoring the immense pain that occurred during this process, Shirou continued to command thousands of swords to fight the enemy.

The destructive force, a blend of physics and mystery, accompanied by deafening bombardments, caused Leticia to experience tinnitus.

However, she heard a cracking sound.

Leticia realized that it was the sound of Saber's spirit origin collapsing.

It has indeed reached its limit.

Since the Holy Grail War began, the battle has been almost non-stop for just half a month.

Moreover, considering that Saber had just been incarnated from an angel, he was considered to have been born into the flesh.

At first glance, he appeared to be perfectly healthy, but in reality, he was burning his life force.

It has reached its limit.

"..."

Leticia clenched her fists with a distressed expression.

Unable to make a sound.

The premonition that the hero he respected and admired was about to be defeated grew stronger.

The girl did not panic.

No, we can't go on like this.

There must be a way.

Lady Joan of Arc has chosen me, Lady Artoria has chosen me... I must help them!

If Saber is defeated, it won't just be him.

The Yggdrasil species, the citizens of Romania, and even the whole world will be affected.

But what can I, so weak and powerless, do?

"Honestly, Saber is so focused on the battle that he's completely ignoring my telepathic commands."

Like a wind chime, a sound rang in my mind.

The beautiful female voice was like a flower, and Leticia was deeply impressed by it.

Although she was momentarily confused by the saint's "revelation," she quickly realized what was happening.

"Miss Aika...?"

"Laetitia...right? Nice to meet you."

The girl couldn't understand why she could speak inside her own head. She wasn't a god or an angel...
