In this crossover anime, Yoshikage Kira longs for a peaceful life.

Next, once Einzbern's side deals with the other Servants, he will order Saber to destroy Berserker.

The ultimate victor will undoubtedly be Emiya Kiritsugu!

however.

When Kiritsugu Emiya actually entered the Great Void, attempting to catch a glimpse of the Holy Grail.

All he saw was 'black mud' covering the ground, and people emerging from it...

"Irisviel?"

Emiya Kiritsugu saw the person's appearance clearly. His expression remained unchanged, but he quietly tightened his grip on the gun hidden in his coat. Why was she here?

"Irisviel?"

The silver-haired girl, dressed in a black celestial robe, tilted her head and revealed a sweet smile:

“I think you’ve mistaken me for someone else. My name is Justessa, Justessa Risleich von Einzbern. Of course, you can also call me ‘Heaven’s Cup’.”

Kiritsugu Emiya's expression shifted slightly. He had long heard that most of the Einzbern's homunculus were created based on the 'Winter Saintess', and Irisviel was no exception. But if the person in front of him was really the Winter Saintess, why would she be here?

'Justeza' seemed to see through Kiritsugu Emiya's question and explained with a smile:

"Originally, with the Lesser Grail present, I shouldn't have awakened. The normal procedure is that the souls of defeated Heroic Spirits would gather in the Lesser Grail, and then the Lesser Grail would bear the power of the Greater Grail. But this Holy Grail War seems to have gone awry. The Lesser Grail refused to assume the mission it should have, and the souls of the defeated Heroic Spirits failed to merge into the Lesser Grail. Instead, they were destroyed by some unknown force."

"But as the souls of the Heroic Spirits were destroyed, the overflowing magical energy had nowhere to go and was partially returned to the Greater Grail, which is why I was able to be awakened by chance. Since I awoke, I have been collecting the overflowing magical energy and competing with the Lesser Grail for the souls of the Heroic Spirits."

"Unfortunately, the souls of most heroic spirits have been destroyed, leaving only pure magic."

Kiritsugu Emiya's eyes flickered; he suddenly realized that his understanding of this Holy Grail War seemed rather superficial.

Before this, he didn't even know there was a difference between the 'Greater Grail' and the 'Lesser Grail'. But since the Greater Grail is 'Yestesa', then the Lesser Grail is probably most likely Irisviel?

If Irisviel refuses to shoulder her mission, doesn't that mean that the Einzbern homunculi have betrayed their long-cherished wish to realize the Third Law?

Kiritsugu Emiya calmly asked:

"So, even without the Lesser Grail, you can still grant my wish, right?"

“Of course, the Lesser Grail and the souls of Heroic Spirits are not necessities for the ritual; they are merely tools for ‘opening a hole’ in this world. As long as your wish is not to go to the Root, but is limited to this world, I can certainly grant your wish. However,”

"Not enough,"

'Justisa' licked her lips with her pink tongue. "Five parts of 'soul' and magic power are not enough to satisfy my vessel! You must kill another Servant and gather at least six parts of 'magic power' before I can grant your wish!"

Her eyes held an undisguised greed, a greedy thirst for the souls and magic of Servants, a thirst for rebirth.

But it was precisely this greed and the extremely obvious suggestive meaning in her words that made Kiritsugu Emiya feel vaguely uneasy.

"What if my wish is to save the world?"

"Of course I can, so hurry up and use the Command Spell. As long as Saber commits suicide, I can grant your wish!"

Kiritsugu Emiya was not blinded by self-interest; instead, he asked in a deep voice:

"Then let me ask you, how will the Holy Grail grant my wish?"

Yustisa tilted her head slightly:

"Didn't you already know how to save the world? So I will grant your wish, just as you have always done."

What are you saying?

Kiritsugu Emiya grew increasingly uneasy, pointed his gun at the girl in front of him, and loudly questioned her:

"Answer me, what exactly is the Holy Grail supposed to do? What will happen if it were to descend into the mortal world?!"

Yustissa sighed helplessly:

"There's no other way. So, the only thing I can do now is let you ask yourself what's in your heart."

She raised her fair and soft hand and covered Kiritsugu Emiya's eyes.

Then, the world went dark.

Two ships were floating on the sea.

There were 300 people on one ship and 200 people on the other, for a total of 500 people, as well as Kiritsugu Emiya.

Let's assume that these 501 people are the last remaining humans in the world.

"Two ships have simultaneously developed large holes in their hulls. Only you can repair them, but while you are repairing one ship, the other will sink due to leaks. Which ship would you choose to repair?"

"Of course, it's the ship with three hundred people."

Kiritsugu Emiya chose the ship with more people without hesitation, but he soon heard his own question:

"What would you do if two hundred men on another ship detained you and demanded that you repair this ship first?"

Kiritsugu Emiya did not answer; his 'body' had already taken action—

Kill all two hundred of them.

"The remaining 300 people abandoned their damaged ship and split into two new vessels to continue their voyage, one with 200 people and the other with 100 people. The hull of one of the ships has been breached again. You are kidnapped by the ship with 100 people, who demand that you repair that ship first. What would you do?"

Kiritsugu Emiya still didn't answer, but cold sweat was already beading on his forehead; he had already guessed the answer.

BOOM!

A dazzling flash appeared before their eyes, and the ship carrying a hundred people sank to the bottom of the sea in a violent explosion.

"Yes, you are right."

"Correct? What do you mean by correct? Are you kidding me?!"

Ignoring his protests, 'Emiya Kiritsugu's' voice continued to ask questions:

The remaining two hundred people were divided into one hundred and twenty and eighty people. It was natural that Kiritsugu Emiya chose to sacrifice the minority and kill the eighty people.

One hundred and twenty people were divided into eighty and forty groups, and the forty were tortured and killed.

Despite consistently sacrificing the minority to save the majority, the mountain of corpses keeps piling up.

finally.

Only three people remained.

Emiya Norikaze, Natalia, and Shirley.

His father, his mentor, and the only person he ever loved.

Should we save one person or two?

Kiritsugu Emiya already had the answer in his heart. Amidst Aya's desperate screams, he pulled the trigger, shooting his father and master, just as he had done before.

But just as the only surviving girl smiled sweetly and prepared to embrace him, Kiritsugu Emiya pierced her heart in despair.

"Yes, you are right."

This time, it wasn't his own voice that rang out, but rather Yustissa's sweet voice:

"This is the only way to save all of humanity."

The scene before Kiritsugu Emiya changed once more; the mangled corpse disappeared, replaced by the large, empty cavity filled with black mud.

Justisa stood in front of him, looking at him with a gratified expression.

Kiritsugu Emiya's eyes were utterly empty; his heart was completely devoid of anything.

The so-called 'miracle' had long lost its meaning for him.

Because he understood that she was right: to save the world, he had to destroy it.

The only way to save all of humanity is to annihilate all of humanity.

In despair, Kiritsugu Emiya raised his right hand, revealing the Command Seals etched on the back of his hand.

"That's right, that's it. Order Saber to commit suicide."

Justeza looked incredibly excited, waiting to devour the sixth Servant.

"By command of the Command Spell, come to me, Saber."

In despair, Kiritsugu Emiya issued an order, but the content of the order astonished Justessa.

Amidst a flash of golden light, the proud young female knight appeared before Kiritsugu Emiya, who, without hesitation, issued his command once again:

"In the name of Emiya Kiritsugu, by Command Spell, Saber, use your Noble Phantasm to destroy the Holy Grail!"

"By Command Spell, Saber, use your Noble Phantasm to destroy the Holy Grail!"

"I command you again with a Command Spell: Saber, destroy the Holy Grail!"

Before Saber could even comprehend the situation, her body had already faithfully carried out the Command Spell's command, and her sword began to weave beams of light.

"do not want!"

Justeza screamed and pounced forward, countless black mud churning and rolling up waves, transforming into towering 'walls' that rushed towards Saber.

At the same time, Saber had already raised the golden sword high.

Without looking back, Kiritsugu Emiya turned and walked out of the Great Hollow. His heart was filled with devastation, and he felt nothing but despair for the world.

If he doesn't want to destroy the world, then the only option is to destroy the Holy Grail.

Whether Saber destroys the Holy Grail or the Holy Grail devours Saber, it is meaningless to him.

"Are you even capable, you little greyhound?!"

In the pure white world, a silver-haired, sweet-looking little girl stomped her feet in anger, "How long has it been? He's already getting bored. What happened to the Holy Grail War that was supposed to satisfy him?"

"If it doesn't work, I'll take over. Let me send him to the Age of Gods!"

"This is part of the plan."

Despite the little girl's merciless mockery, the blue orb remained calm:

"The Holy Grail War is merely filtering out elements that interest him; it doesn't fit his definition of 'peace,' so of course it bores him. As for the Age of Gods, civilization without humanity is meaningless, and he'll only tire of it faster."

The silver-haired, bright-eyed little girl stood with her hands on her hips and said confidently:

"How do you know it won't work? Kamishiro clearly has many capable people, so let me take over!"

"Negation, now is my reunion."

"Then why don't you draw a card!"
