Chapter 813

If it's the Third Magic, then even something like "reshaping the world" can be easily accomplished.

The problem is that, currently, the only known entity capable of casting Third Magic is the uncorrupted Fuyuki City Greater Grail.

Like Shirou's past involvement in the Romania Holy Grail War...

If Shirou Amakusa Tokisada were to truly win, the absurd proposition of immortality for all humankind could be realized.

So who exactly cast the Third Magic?

The name of a girl he had recently met flashed through Shirou's mind, but he lacked concrete evidence at the moment.

"What's wrong... why do you look so serious?"

"It's nothing, we've had enough fun in the water, haven't we?"

"Uh-huh."

As Irisviel got up from the children's inflatable pool, Shirou looked at her retreating figure and asked a question.

"Eiri, if I said I wanted to turn the world back to how it was before..."

"Sure."

Irisviel smiled and said, "I will unconditionally support whatever decision Shirou makes."

"Oh, I see. Thank you..."

The two said nothing more and began tidying up the yard.

"Oh, right, Eiri."

"What?"

Shirou asked curiously, " In the Fourth Holy Grail War, was the Heroic Spirit you summoned still Saber?"

Artoria Pendragon is the most unique Heroic Spirit, participating in the Holy Grail War as a living human.

However, in the original world, she eventually became a goddess... So what's going on now?

Irisviel shook her head. "No, I summon Caster."

"Huh? Caster? Wait... could it be...?"

Shirou seemed to see the cheerful face of a certain nightmare, and his heart skipped a beat.

"That Caster, could she be calling herself Lady Avalon?"

No, that's not it.

"No, that's great!"

Shirou had just breathed a sigh of relief when he heard Irisviel say this.

"That's what Caster calls herself--"

The oldest and strongest Magical Girl of flowers, whose origin is also her peak, True Magic ☆ Meli.

Shirou:"..."

Volume 10: 484 Shirou Returns Home?

"Hey!"

Illya's voice echoed in the dimly lit underground tunnel.

With the girl's shout, the released Magic Bullet struck the barrier and bounced back.

"Sister Luvia, was that okay?"

"Yes, it's fine after just a quick check to confirm its operation."

Then, a loud explosion came from deep inside the tunnel, and Miyu emerged from it.

"We've broken up what appears to be the hardest rock layer; now we can use machinery for excavation."

"Miyu, you've worked hard."

That evening, he followed Rin Tohsaka and the others, taking his younger sisters to an abandoned factory in the suburbs.

The reason I went to a place like this during summer vacation was to prepare for retrieving the last... that is, the eighth Class Card.

"Even Magical Girl are wearing helmets while digging; I have absolutely no Magical Girl vibes."

"Really...?"

As Ruby and Kuro mentioned, everyone was wearing helmets with "Safety First" written on them, including Illya Miyu dressed as Magical Girl, making the scene very surreal.

And what they were holding weren't shovels, but Kaleidoscope Wand...

Chloe raised her hand.

"Although it's a bit late, I have a question."

Rin crossed her arms and looked at her. "Huh? What?"

"No matter how we construct here, isn't our destination a much deeper underground?"

"Yes, that's true." Illya nodded.

Ruby: "That's alright, because the Mirror World is a superposition of possibilities."

Because we jumped, we will choose the relative state from the superposition of states.

Sapphire: "Just think of Schrödinger's cat, and you'll understand."

Illya, sweating profusely, said, "Although... although I don't quite understand, it's good that there's no problem."

"Don't explain quantum mechanics to elementary school girls," Shirou thought to himself.

In short, the hidden eighth card is located underground in this land.

Once that location is reached, it can be connected to the Mirror World as usual.

Since they couldn't damage the foundation, Illya and the others had to dig little by little, which would take several more nights.

"... The eighth card is right ahead."

Standing beside the group, Kuro looked into the dark depths of the tunnel and spoke.

Hearing her words, Illya also looked in that direction.

Ahead lay a chilling darkness; what kind of enemy was the final Class Card?

Just as the girl was feeling uneasy, she heard a rustling sound from the side.

What was that sound?

"Wait a minute, we've wasted the gems we used to activate it!"

Rin Tohsaka called out to Luvia was continuously feeding gems into some kind of device like she was throwing coins into a slot machine.

"Oh dear~ Look at you, so stingy and poor~"

"What did you say?"

"And it's made with my gemstones, you know?"

"That's not the issue! I just can't stand watching money disappear right before my eyes!"

"Oh, hehehe! That's so typical of you. So persistent even though it's not your own money!"

People like you are called misers. You're so ugly and pathetic, it's unbearable to look at!

"You...!"

Rin Tohsaka and Luvia started fighting as usual.

Shirou sighed, walked over, and asked, "So, how's the progress?"

Seeing the boy approaching, the two women quickly separated, pretending nothing had happened.

"Yes, we're about 30% done," Rin said. "It's all thanks to Illya and the others for their help."

Illya scratched her head sheepishly, "Well, we've really been enjoying summer vacation... I feel a little embarrassed."

"What are you saying? Playing is a child's job."

"Oh, right, speaking of having fun... here's your payment for helping out this time."

As she spoke, Luvia took out a stack of tickets with cute lions painted on them from her wallet and handed them to Illya.

"Ah... this is... an amusement park!!"

Illya held up the theme park ticket above her head, her eyes shining.

Then.

Shirou, as one of the leaders who brought the children, accompanied Illya and her friends to the amusement park.

He was one of the team leaders because, besides him, a male high school student, there was another real adult in the team.

"Hehe, I feel so happy~ Shirou ~"

Irisviel touched her cheek and said with a smile.

"Haa..."

Shirou sighed. This person is no different from a child.

"Let me sit! Let me sit! Let me sit! I guarantee you'll keep screaming!"

One of Illya's friends, Tatsuko, was just as excited as when they went to the beach last time.

This time, Illya and the others were prepared; Moriyama tied her to her body with a rope.

"This amusement park is quite beautiful."

"Because it was only recently built."

"But, even though it's an animal-themed park, there are only lions inside?"

"Because Mr. Lion is the mascot here. He's so cute, I feel like one of these is enough," Illya said.

Isn't it cute...?

Shirou felt that Mr. Lion looked like Artoria hadn't eaten all day.

"What an incredible space."

As she walked toward the first facility, Miyu quietly muttered to herself.

Shirou asked curiously, "Is this Miyu's first time at an amusement park?"

"Yes, because the place I stayed before didn't have it."

"Oh, I see. Then we must have an even better time today!"

"Yes, Mr. Shirou."

"No, no, no, this isn't a mission... you don't need to take it so seriously."

Irisviel clapped her hands twice. "Alright, everyone, look here."

Now that we're at the amusement park, I'd like to clarify some important points first.

Then, she began to explain to the elementary school students.

Oh, surprisingly serious. Shirou's opinion of Eiri has changed somewhat. Did he underestimate her before?

After all, she was once Master cleared the Holy Grail War in one night, so let's trust Eiri a little more.

"Illya's mother is a real beauty."

"Could I switch places with my mom? Even just for one day would be great."

The elementary school girls started talking about Irisviel.

"Wow... Madam, you're so beautiful! Your skin is so smooth, and you smell so sweet... You're perfect, Madam."

But! If they were to fight, my mom would definitely win!

Shirou: No, no, no, you're overthinking it...
