Chapter 772

The location was the rooftop of the teaching building, and Rin had set up a barrier to keep people away beforehand.

"What exactly happened yesterday?"

Shirou was referring to was the unusual phenomenon of his younger sister, Illya, becoming two people.

"How would I know about such a thing? Illya becoming Heroic Spirit was already surprising enough, how could I possibly control such an unexpected situation?"

No matter how I think about it, I still have absolutely no idea what happened.

"Yes. Even if we wanted to investigate in detail, that black-clad Illyasviel escaped."

Yesterday's events happened so suddenly; just as everyone was about to approach Black Illya to talk to her, she vanished in a flash.

"She escaped so fast... that speed really has Illya's style..."

"That speed and agility in escape are beyond human capabilities. I think that's probably Archer's power."

"Archer's power?"

Shirou couldn't help but recall yesterday when Illya used "Phantasm Summon" to transform into an archer; she had used Projection Magic...

"Yes. After that, Archer's Class Card disappeared. It vanished after Illya used it."

"So, that black Illyasviel and Archer's Class Card are somehow related?"

Rin crossed her arms and nodded. "It's more natural to think that way."

Illya used Archer's Class Card to transform, and then, for some reason, the black-clad Illya appeared.

That's my guess, although I don't know what it actually is.

Shirou fell into deep thought.

Illya had used "Phantasm Summon" before when fighting the corrupted assassins, but nothing like what happened yesterday had occurred.

In that case, the cause might lie in yesterday's Great Cavern.

Shirou reminisces about the black Illyasviel.

She has the exact same appearance and figure as her sister, and wears a very revealing red combat suit that exposes her entire abdomen.

She had slightly pinkish silver hair, beautiful Kohaku eyes, brown skin, and red markings near her navel.

"Can we talk to Illya?"

Rin shrugged. "Who knows? She ran away without saying a word."

Luvia narrowed her eyes. "If she possesses the power of Heroic Spirit, that would be quite troublesome. She might even turn into Corrupted Heroic Spirit."

"Will we have to fight like before again...?"

Shirou was somewhat reluctant.

Although it's unknown what kind of being it is, the child's appearance is exactly like Illya's.

He hopes to resolve the issue through dialogue if possible.

Rin and Luvia noticed Shirou's attitude and exchanged a glance.

"In short, we first need to figure out what that black Illya is."

"Yes, we know nothing about it yet. We need to gather intelligence before discussing countermeasures."

"I understand." Shirou nodded, agreeing with their opinions.

That's how it is.

First, we need to find the black-clad Illya, and then conduct various investigations.

What kind of being is she? Can we talk to her? Will it escalate into a fight?

To find out these things, we first need to find the child.

After the strategy meeting ended, Shirou and the others returned to their classroom.

On the way back, Shirou kept thinking about Black Illya.

It's not about how to deal with it, but how you want to treat the child.

At that time yesterday--

The child glanced at Shirou one last time.

In the instant of escape, just before the reversal.

Her eyes seemed to be desperately trying to tell a story.

The look in Black Illya's eyes seemed to hold a plea for help.

This reminded Shirou of Illya when he was a child.

Although she has become more independent recently, Illya still shows that same look in her eyes when she asks Shirou for help.

From the moment he saw that look in her eyes, Shirou could no longer treat her as a complete outsider.

Shirou wanted to help her and do something for the child.

If I told Rin and Luvia, they would definitely think I was fooled by her similar appearance to Illya.

But Shirou simply couldn't ignore that pleading look in his eyes.

Besides...

Girls shouldn't run around outside wearing such revealing clothes. Shirou must give her a good talking-to when he gets the chance.

During lunch break, Shirou heard some terrible news from Issei.

"Huh, Illya's been taken to the infirmary?"

"It seems so. Go and take a look, Amamiya."

"Thank you, Issei. I'll go check on the situation right away."

Issei heard from Teacher Fujimura that Shirou's younger sister had been sent to the infirmary and was sleeping there.

Incidentally, Teacher Fujimura is Illya's homeroom teacher and also the advisor for Shirou's Archery Club, which is why he knows both siblings.

Speaking of the infirmary, it's the place where the school nurse, Ms. Kare Hiji Des Acrete, works (the den of demons).

This worried Shirou in every sense.

Was Illya injured, or was she feeling unwell?

Also, did that teacher do anything strange to her?

Although it's often said not to judge a book by its cover, that person's actions and words are completely untrustworthy.

Shirou recalled that he had heard that person say something like that sometime in the past.

"The reason I became a health teacher is because I enjoy observing injured children up close."

Therefore, healthy children are of little use.

If you have recovered, please leave the infirmary promptly, as you will be interfering with my work.

Oh right, it was when Shirou took his junior who was injured during club activities to get treatment that she made her statement.

At that moment, both he and Sakura stood there, stunned and speechless.

Shirou couldn't bear to entrust his important younger sister to that kind of person, so he quickened his pace and rushed to the infirmary.

In the pure white room, Illya sat on the bed, Miyu sat beside her.

"Illya, are you alright? Especially, did Ms. Kare do anything strange to you?" (whispering)

"Ah, brother. Uh, um... don't worry about the part you're speaking softly in the second half, since the teacher isn't here."

Illya forced a tired smile and said, "My injuries aren't serious."

"Oh, I see. It's good that both things are alright. If the teacher were here, I would be worried about both things."

Upon learning that his adorable younger sister hadn't been harmed by the wicked teacher, Shirou pressed his hand to his chest and breathed a sigh of relief.

So, what happened?

Shirou asked Miyu, who had also come to visit Illya, Miyu.

The black-haired girl said with lingering fear, "Well, actually, strange things started happening this morning..."

"Something strange?"

This morning, Shirou didn't go out with Illya and the Tohsaka because he wanted to discuss Black Illya with Illya and the others.

According to Miyu, strange things have been happening around Illya ever since she started school this morning.

"The flowerpot fell off and was almost hit by a truck..."

Ruby added, "And there's more! Miss Illya was attacked by both a black cat and a crow at the same time!"

"It's not fun at all! It hurts terribly!"

"Oh, I see..."

Shirou looked at the top of Illya's head; no wonder her hair was such a mess.

The examples listed above seem to represent only a small part of the situation; various other unexpected events have apparently occurred.

Several times, Illya nearly lost her life.

Illya: "Sigh, maybe I should just leave early today..."

Shirou: "Illya, you must be very tired."

Ruby: "Of course, even the worst prank shows can't go that far."

Miyu: "I've been watching from the sidelines the whole time, and it looks really tough on me."

Illya looked like she'd had enough.

Strange things seemed to keep happening to her not only at school, but also during her classes. Shirou could understand her feelings.

Shirou gently stroked Illya's head.

Being loved by her brother finally gave Illya a chance to vent her emotions.

The girl raised her hands and shouted, "Seriously! What's going on?!... Pfft!"

Just then, something flew in through the open window of the infirmary and hit Illya right in the face.

Upon closer inspection, it was a soccer ball.

The football struck Illya's face with astonishing force.

Moreover, that aura did not weaken at all, and continued to swirl around the girl's face.

"I- Illya... are you alright?"

Shirou clicked his tongue, it looked like it was in a lot of pain.

Miyu also looked terrified, while Ruby remained unchanged, happily wriggling her body.

"Hehehe, that's fantastic, Miss Illya. You're really amazing."

"..."

Illya trembled silently, her pent-up anger finally about to explode.

At that moment, the ball that had been spinning and hitting Illya's face suddenly broke apart.

With a loud bang, shattered fragments scattered around Illya.

The scene was truly tragic; Illya's face was sunken and flushed red.

Shirou couldn't find any words of comfort.

"Ugh--!"

"Hahahahahahahahaha!"

Illya finally snapped, and Ruby burst into laughter, naturally becoming the target of her anger.

Illya slammed the Kaleidoscope Wand to the ground and dashed out of the infirmary.

"Hey, wait! Illya, where are you going without warning?!"
