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

At such high speeds, aren't you afraid your wife might accidentally crash into the highway guardrail and fly off the mountaintop?

It doesn't matter if she's a follower, but you'll probably have a hard time surviving, right?

Kira Yoshikage opened his eyes, grabbed Asagami Fujino's small hand and licked it, then asked in confusion:

"What did you say?"

"It's nothing, you can continue."

Saber withdrew her gaze, her face expressionless.

She really shouldn't have had any expectations of this man.

Kira Yoshikage, unsuspecting, opened his mouth and took the girl's delicate, snow-white finger into his mouth, causing a blush to spread across her fair cheeks.

Although she neither dislikes nor rejects it.

However, since it happened in front of other people, and one of them was Kira-kun's wife, having an affair in front of his wife was indeed a bit too exciting.

The car swayed along the winding, undulating road, its tires screeching under the strain. Saber, realizing she couldn't stop it, could only silently unbuckle her seatbelt, thinking that if anything happened, she would immediately grab Irisviel and jump out of the car.

Fortunately.

Although the process was thrilling, Irisviel's driving skills were indeed 'not bad'.

Although we nearly crashed into the guardrails several times, we eventually made it safely off the remote mountain road and into the vast primeval forest on the outskirts of the city.

Unlike the Matou and Tohsaka families, who established their bases in the city, the Einzbern family has always stayed away from worldly affairs.

That's why the Einzbern family spent a great deal of money to buy this forest and build a castle there specifically for the Holy Grail War.

The castle was shrouded in multiple layers of illusion and magical barriers, making it completely unknown to ordinary people. Even though it had been uninhabited for sixty years, by the time Yoshikage Kira and his companions arrived, the android maids who had arrived earlier had already tidied the place up perfectly.

"elder brother!"

Pushing open the castle's magnificent gates, the little girl's clear, joyful voice reached their ears. With a delighted smile on her face, the black-haired girl ran down the stairs and threw herself into Kira Yoshikage's arms.

"Eh~!"

Irisviel looked at the little girl in front of her, who was about the same age as her daughter, and asked curiously:

"Is she Kira-kun's daughter?"

"No, she's my adopted sister."

Kira Yoshikage sighed. Why would even Irisviel think this was her daughter?

She must have been corrupted by Yang Nai!

"Fujino-neechan."

The little girl obediently called out the girl's name, then timidly looked up at the other two girls.

"I'm Kira-kun's wife~"

Irisviel crouched down and lovingly stroked the little girl's head. "You can call me Irisviel-neechan, and this is Saber. You can call her Saber-neechan."

"Hmm~"

Although it was strange that someone would be called Saber, the little girl still obediently called out:

"Sister Alice, Sister Saber."

"Good girl~!"

Hearing the little girl's call, Irisviel's maternal instincts kicked in, and she gently hugged the little girl in her arms. "So, what's your name?"

The girl's soft embrace dispelled the little girl's awkwardness and fear, and she answered softly:

"My name is Sakura, Matou Sakura."

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

"Zouken Matou, where is Sakura?"

Matou Kariya dragged his broken body into the study of the Matou residence, looked at the old man in front of him with hateful eyes, and questioned him through gritted teeth.

Across from him, Zouken Matou narrowed his eyes slightly and sneered disdainfully:

"Yan Ye, who gave you the courage to question me?"

"Ughhhhhh!"

Kariya Matou screamed and collapsed to the ground, writhing in agony as the Crest Worms within him began to devour his flesh once more. This time, however, it wasn't due to the draining of his magical energy, but simply because he was being controlled by Zouken Matou.

Do you think you can defy this old man now?

Zouken Matou, leaning on his cane, walked up to Kariya Matou and coldly warned, "Don't forget who gave you this power!"

The so-called "carved insects" were originally cultivated by Matou Zouken and were naturally under his control.

From the moment the Crest Worms were implanted into Kariya Matou's body, he was destined to be controlled by Zouken Matou. Any act of resistance would result in the excruciating pain of being devoured by countless worms!

Of course, Kariya Matou knew these things.

But—

"Old man..."

Despite the physical pain, Matou Kariya stubbornly raised his head to look at the emaciated old man before him, a mocking sneer tugging at the corner of his mouth.

"Ok?"

Zouken Matou's gaze happened to fall on the back of Zouken Matou's right hand, where there should have been three bright red Command Seals. But now, only the marks left when the Command Seals were used remained!

Zouken Matou's expression changed drastically, and his body immediately tried to disperse into countless insects and escape.

But before he could put it into practice, the girl's loud shout rang in his ears:

“Clarent Blood Arthur (rebellion against my magnificent father)!”

As the true name of the Noble Phantasm was released, ominous red lightning surged in from outside the door, completely engulfing Zouken Matou's body, which was about to be 'disassembled', in the blink of an eye. Every insect was mercilessly torn apart amidst rustling screams, splattering green, foul-smelling liquid.

But before these liquids splashed onto the ground, they were further torn apart and decomposed by lightning, eventually turning into nothingness.

Although she was slightly outmatched in the clash of energy with Saber, that doesn't mean her Noble Phantasm is weak!

At least in terms of exterminating insects, her Noble Phantasm is quite useful.

"Cough cough!"

After losing Zouken Matou's control, Kariya Matou's Crest Worms gradually calmed down, but even so, he still vomited a large pool of blood, which contained dozens of disgusting, wriggling worms.

Mordred, who had originally intended to help him up, stopped in her tracks and asked casually:

"Is it really necessary to go through all this trouble? I could kill an enemy of this level with a single sword strike, so why waste my Noble Phantasm?"

She didn't care, but using her Noble Phantasm was a huge burden for Matou Kariya. Even though she had specially controlled the efficiency of her magic output, it was still something that Matou Kariya could not easily bear.

Each time his magic was drained, his already limited lifespan became increasingly precarious as the Mark Worms gnawed at it.

"Have!"

Matou Kariya slowly climbed up, using the desk as support, and stomped on the insect hopping around in the pool of blood, gritting her teeth as she said:

"If you don't use your Noble Phantasm, that old man will turn into an insect and run away. Didn't you just see that? His strength may not seem like much to you, but when it comes to escaping, even Assassin might not be able to match him!"

To create this opportunity, he spared no effort in using up all his Command Seals.

Otherwise, the old bug might use Command Seals to forcibly control the Berserker by manipulating his body. Once controlled by the old bug, given his cautious nature, he would definitely hide, making it almost impossible to ambush him again.

However, this was largely thanks to Berserker temporarily regaining her senses and being able to use her powerful, wide-range Noble Phantasm, which caught the old bug off guard.

otherwise……

A deep sense of dread flashed in Matou Kariya's eyes. Even though he had destroyed the old insect's body, Kariya was still filled with fear of him.

"You are the Master, you make the decisions."

Mordred shrugged, hoisting his greatsword onto his shoulder amidst the clanging of armor. "So? What do we do next?"

"That old bastard is still alive!"

Kariya Matou clenched his fists, his eyes filled with hatred and rage, and said in a deep voice, "His Crest Bugs must still be hiding somewhere in this house. Berserker, go find the bugs! Exterminate them all!"

Mordred frowned slightly:

“I have no objection, but your health…”

"I can handle it!"

Kariya Matou gritted his teeth and said, "As long as I can kill him, it doesn't matter if this body is completely eaten by insects!"

"I'll use it sparingly."

Mordred clicked his tongue, shouldered his greatsword, and walked out of the room. "But you better not actually die. I can't act alone without a supply of magic."

"Don't worry! I know what I'm doing. Although I won't live much longer, even with my Noble Phantasm, I can still let you unleash it a couple more times! Even if I really do die, I will definitely find a new Master for you before I die!"

Matou Kariya grinned, his mouth stained with blood, and laughed heartily.

Unlike other Masters who participated in the Holy Grail War, he had no ambition to obtain the Holy Grail.

He only wanted to save Sakura, and to kill the monster named Zouken Matou and the magician named Tokiomi Tohsaka. With the power of the Berserker, he could achieve his dream even without the Holy Grail!

But all the Servants came for the Holy Grail, and although he never asked Berserker, he could be certain of that.

But since Berserker is willing to risk losing her Master to help him wipe out Zouken Matou, then as his Master, he can't be too selfish. If he really can't hold out until the day of victory, then Berserker should be handed over to another Master, as long as her wish can be fulfilled.

Although Sakura is still missing, Kariya Matou has no other choice.

If Zouken Matou cannot be killed, even if Sakura is still alive, she will eventually be implanted with the Crest Worm by the old bug.

On the contrary, as long as Zouken Matou can be killed.

Even if he never sees Sakura again, he can at least make sure that Sakura can live a happier life in the second half of her life than she does now!

Of course, all of this is predicated on the complete killing of Matou Zouken.

so.

Even if it costs him his life, he will kill Zouken Matou!

Even if he has to go to hell, he'll drag Zouken Matou down with him!
