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

"Thank you, Amber and Jade. You're so sweet."

Irisviel smiled and ruffled the two sisters' hair, then displayed the images captured by the barrier on the crystal ball.

The intruder was dressed in a jet-black robe, which emanated an ominous and malevolent aura. The crimson patterns on the robe, as if stained with blood, appeared and disappeared in the jungle.

He was followed by a group of 12 children, all of whom appeared to be underage elementary school students.

They all had blank stares, as if sleepwalking, and staggered along with Caster as they wandered aimlessly through the forest.

"Is that Caster?"

Irisviel murmured softly.

The 'Clairvoyance' magic has a wide range, but the actual defensive barrier is only five kilometers in diameter. Caster clearly saw through this and never actually entered the barrier's range, only hovering at its edge.

"Your Highness!"

Caster's beast-like eyes suddenly looked upwards, staring directly at Irisviel through the crystal ball, his tone incredibly fanatical:

"You have defeated the false creations of that deceitful god; please allow me to offer you the most sublime ceremony!"

“Saber”.

Seeing that Saber was staring at the group of children behind Caster, Yoshikage Kira called out.

"call!"

Saber took a deep breath and said in a low voice:

"Give the order, Irisviel!"

Irisviel looked at the children behind Caster, who were about the same age as Ilya, a hint of pity flashing in her eyes, but she still firmly gave the order:

"Then, Saber, Berserker, defeat Caster! Show no mercy!"

-----------------

When Saber appeared outside the barrier, rushing in like a whirlwind, Caster immediately bowed his head, kneeling on the muddy ground like a subject before a king, and respectfully said:

"We've been waiting for you for a long time, Your Highness!"

"I don't have a man like you among my subjects!"

Sabe's tone was extremely cold, showing no intention of arguing with him whatsoever, and she drew her sword directly at him.

"How could this be?!"

Caster's already bulging eyes grew even larger, and he frantically grabbed at his hair, letting out mournful howls like a dying beast.

"Oh, oh, woo woo woo..."

“It is I! I am Gilles de Rais, your most loyal servant! I have always longed for your resurrection, and I have always awaited the day when I could see you again. This is why I have come here. Joan of Arc!”

Saber had nothing to say and no interest in listening to Caster's long-winded explanation.

She wanted to cleave Caster in two with a single sword strike, and without a moment's hesitation, she took a step toward Caster.

Caster sensed the murderous intent in Saber's movements, stopped his weeping, and suddenly grabbed a boy's skull, holding him in front of him as a hostage.

"Oh—Joan of Arc, your eyes, burning with rage, are truly captivating!"

Caster looked up, tears of emotion welling in his eyes. "Do you hate me that much? You won't even acknowledge that I was once your subject. Yes, you should hate me. I betrayed God's love, and you will never forgive me. You are more devout to God than anyone else!"

"As pure and holy as you are, surely you wouldn't abandon these children?"

Caster gently stroked the boy's skull, simultaneously dispelling the enchantment spell he had cast on him.

The boy's eyes went from a brief moment of confusion to one filled with terror. Realizing he was being held by a strange person, he began to struggle desperately, crying out and trying to get help from the seemingly gentler girl.

"Big sister, big sister, save me!"

“Go, child, God’s devout believers will save you.”

Caster spoke with a compassionate tone, releasing the boy's skull and gently pushing him toward Saber, who was approaching with a sword.

The young child seemed to understand that the blonde girl rushing towards him was his savior, and cried out as he opened his arms to try to hug her.

Caster's face lit up with a joyful and benevolent smile; the saint would save him, just as she had saved France.

The pure maiden would put down her sword and instead embrace the terrified boy, gently comforting him.

Then he will tell the saintess what... is.

Caster's thoughts came to an abrupt halt as the red greatsword slashed across the boy's head, blood gushing out, and the small body collapsed into a pool of blood.

This action was completely unexpected by Caster, causing his smile to freeze for a moment.

The black-armored knight suddenly appeared beside Saber and kicked the headless corpse into the distant forest.

"She'll pity you, but she won't!"

Mordred ran towards Caster from the other side, laughing wildly. As planned, she would clear all obstacles for her father!

But soon, Caster's smile became even brighter, and her voice became even more excited;

"Yes, yes, yes! That's it, that's it! Your Highness, abandon that hypocritical god, and embrace blasphemy with me! Ah, two saints! Saints who sacrificed themselves for the god, saints who saw through the hypocrisy of the god, there are no fakes at all, only the real! They are all my saints!"

Saber's beautiful face remained aloof; she neither rebuked Mordred's behavior nor wavered in the face of Caster's words.

Once she's on the battlefield, her heart becomes a sword.

A sword that is incredibly sharp and gleaming.

A sharp sword that utterly deceives.

This distance.

She could sever his head in less than a second!

"Please forgive my rudeness, Holy Virgin!"

But Caster clearly guessed what she wanted to do, gracefully stepping back while covering her chest, she opened her arms wide with fervor, "This is the ritual I prepared for you... for all of you!"

Snap! Snap! Snap!

In an instant, the small bodies of the eleven children who came in front of him as he retreated exploded in two.

But what gushed out of their bodies was not red blood, but black tentacles as thick as a human arm!

It was a monster summoned from another world, still bearing the flesh and blood of hostages.

They have no limbs or buttocks, and are made up of countless tentacles. At the base is a ring-shaped mouth, which is like the mouth of a shark, with blade-sharp teeth that are indescribable.

Even the boy who was killed earlier had his body and head explode at the same time, with countless tentacles extending out from the scattered wreckage!

Dozens of monsters formed an impenetrable defensive line, protecting Caster while also surrounding Saber, who was trapped within it.

They stretched out their dark, slippery tentacles, trying to trap the radiant knight's limbs and plunge the holy maiden into the mud.

"Don't even think about it!"

The black-armored knight charged in, laughing wildly. With disproportionately swift swings of his greatsword, he severed the tentacles and bodies of the monsters at the root, clearing a clear path for Saber to advance.

"Ahhh—ahhh! Such perfect coordination! Such perfect posture! I cannot be impolite, Holy Virgin, let me pave the way for you!"

Caster's gaze grew increasingly infatuated, his expression increasingly fanatical, as he pulled a black book from his pocket.

The book's cover was damp and shimmered with a strange light.

But before he could open the book, Saber had already swung her sword at him, forcing Caster to raise his arm and use the book in his hand to block the invisible sword that was coming at him—even though he was just Caster and he couldn't see the outline of the sword, his warrior instincts still allowed him to accurately block this fatal blow.

Just when he thought Saber would launch an even more swift attack and was preparing to retreat,

He suddenly saw Saber wave her hand and throw something at him.

"then!"

Caster initially didn't want to accept it, but upon hearing the girl's voice, he inexplicably caught the flying, glittering round cake.

It was a coin, an ordinary 500 yen coin.

"what is this?"

Caster was somewhat taken aback and instinctively wanted to ask a question.

However, the next second, he saw Saber pull back and create distance between them.

Meanwhile, the magic of the sky's 'all-seeing eye' was still 'observing' him.

Caster raised his palm, trying to examine the coin in his hand closely.

BOOM!

An invisible explosion spread throughout his body along with the coin.

Before he could react, the explosion silently engulfed him.

Nothing was left, including the Noble Phantasm with its black cover.

Pa~!

The coin fell from the sky, sank into the muddy ground, splashing a small puddle of mud, but remained intact.

boom!

As Caster 'disappeared', the monsters on the ground, which had been constantly killed and multiplied under Mordred's attacks, suddenly exploded without warning.

Monsters summoned by offering flesh and blood as sacrifices will, once deprived of their magical power, revert their waving tentacles back to mangled, bloody corpses—the remains of children, young and broken.

Despite her victory, an indescribable pity still flickered in Saber's eyes.

"Stop with your cheap sympathy!"

Mordred stepped forward, sword in hand, and sneered, "I killed them. Do you still want to avenge them?"

She knew her father well, if not completely, but at least well enough in certain aspects.

Even though she had been warned, even though she had made assurances, even though she believed that these children's inner selves had been turned into monsters, as long as they retained their human form, as long as they hadn't revealed their hideous faces, she couldn't bring herself to swing her sword at them.

Mordred is different.

She doesn't care whether her enemies are old or young; as long as she knows they are enemies, she will mercilessly kill them all!

“You’re going too far, Mordred.”

Saber looked at her quietly and said softly.

"Me, extreme?!"
