Chapter 821

At that moment, she stared wide-eyed in disbelief.

Why... is my brother here?

Why... is my brother happily drinking black tea with Illya?

Without thinking too much, Miyu excitedly rushed forward, shouting "Brother!"

As a result, this naturally led to a misunderstanding.

"Hey... Miyu is Shirou's sister from Parallel World?"

"I'm so sorry, I didn't know it would turn out like this... I'm so sorry for causing you both so much trouble..."

Miyu confessed everything to the two of them, feeling guilty, including the fact that she came from Parallel World.

This was a secret that shouldn't have been revealed, but for some reason, the girl felt she could trust these two people.

Perhaps it's because of Illya's words, "You can stay as long as you want," or perhaps it's because Shirou and his brother are from different worlds, yet the same person.

He thought the brother and sister would doubt his words, but they just glanced at each other and then gave Miyu a kind smile.

Illya: "So, in that case, I'm Miyu's older sister!"

Miyu: "... Huh?"

Shirou: "No, no, no... You're younger Miyu, right? Miyu is the older sister, and I'm your older brother."

Illya: "What the hell! Shirou's the one acting so arrogantly! I don't care, I want to be the older sister!!"

The brother and sister accepted her, this girl of dubious origin, almost as if it were a joke.

They not only provided her with shelter, but also helped her retrieve her lost Class Card.

"How lucky I am," Miyu couldn't help but think.

Having just arrived in this helpless world, I've already met people who are willing to treat me kindly.

So...

How did I repay them?

Even Aesop's fable "The Farmer and the Snake" is probably no better.

Illya and Mr. Shirou saved themselves, but I betrayed them and hurt them.

Because she wanted more of Shirou's attention, and because she didn't want their relationship to remain at the level of "my sister's friend"—

I destroyed everything with my own hands.

He clearly wanted to repay their kindness, but due to a moment of confusion, he made the wrong wish.

"I hope... that Mr. Shirou will value me as much as he values Illya, and cherish me like a younger sister."

That was Miyu, Divine Child, having a forbidden dream that she absolutely should not have.

Driven by intense obsession, a miracle (the Third Magic) answered her wish.

The world gave the girl the opportunity to meet her siblings in a different way.

This time, Illya remains Miyu's irreplaceable friend, but Shirou no longer sees her as "a friend's sister" but rather as "a second sister."

And so, a world where only Miyu finds happiness was born.

In contrast, Shirou and Illya's originally happy life was destroyed.

Recalling everything, Miyu was overwhelmed by guilt and felt so desperate that she could hardly breathe.

What have I done...?

It's all my fault...

Whether it's a conspiracy or a criminal, from the very beginning it wasn't someone else, but me.

I have already...

I no longer deserve to stay by their side.

--Swish.

In an instant, the girl's vision, blurred by tears, cleared, and Shirou's face appeared before her.

Even seeing him so clearly, I could sense the worry on his face.

Even though it has been confirmed that Miyu is the culprit who ruined his and his sister's lives, Mr. Shirou still cares about her.

"Miyu, are you alright...? I'm sorry, I shouldn't have done that so suddenly... You weren't mentally prepared, were you?"

A surge of joy welled up in Miyu's heart.

Mr. Shirou didn't blame me, nor did he hate me...

Even after realizing the truth, he still treated me like family; after all, it was just a child's momentary lapse of judgment...

"Waaaaah!!!"

The girl covered her mouth.

She felt disgusted by her own shameless thoughts.

He had clearly manipulated everyone's lives, yet he was still forgiven...

This is incorrect.

I deserve to be punished and pay the price.

I do not deserve Mr. Shirou's concern.

I am not worthy to continue being Illya's friend.

By the way, I wasn't originally from this world.

That's probably why it turned out this way...

Because.

Miyu Sakatsuki's very existence is a mistake for this world.

"Sorry..."

The girl murmured.

"Miyu?"

Illya noticed something was wrong and shifted her gaze from the dazzling fireworks display to her friend's face.

"Waaah! W-what's wrong! Why are you crying?"

She was stunned when she saw Miyu with tears streaming down her face.

"The fireworks were beautiful, but is it really necessary to be this emotional?"

"... goodbye."

A pale blue light emanated from beneath Miyu's feet.

"Huh?"

Illya and Chloe were still confused about the situation.

Shirou realized what was about to happen and quickly reached out to grab Miyu's hand, but he grabbed nothing.

"Wait! Miyu!"

Miyu transforms into Magical Girl, leaps into the air, and becomes a shooting star in the night sky.

A commotion arose among the surrounding tourists.

"Hey! Look! What's that?"

"I couldn't see clearly, but... it looked like a girl was flying in the sky... and then she flew away..."

"Was that also a performance at the festival? Wow, that's amazing!"

The fireworks display venue descended into chaos in an instant.

Illya stomped her foot angrily and shouted at the sky:

"W-What's going on, Miyu?! No matter how beautiful the fireworks are, you can't get so excited in front of the public that you transform!"

"This is terrible! I'm definitely going to get yelled at by Rin and Luvia!"

"..."

Shirou stared silently in the direction where Miyu had disappeared.

Should we go after them?

Just as I was hesitating, a hand reached out and grasped mine.

"Kuro..."

The brown-skinned girl gripped Shirou's hand tightly and said with a somber expression.

"Brother... let Miyu be alone for now."

"Um."

Shirou nodded.

Miyu is a sensible and mature girl, so trust her.

On the third day after the festival ended, Shirou and the others gathered at the newly rebuilt Edelfelt Mansion.

"Congratulations on the completion of the reconstruction of the Edelfelt Mansion. I'm sorry, Luvia, I couldn't offer you any proper congratulations..."

"Oh dear, Shirou... We don't need to be so formal with each other."

Oh, hehehe... so please don't mind it."

Surrounded by a group of maids, Luvia came to Shirou's side and hugged his arm.

"Uh... Luvia, it's too close."

Hey! You two, separate now!

That's exactly what I'm saying!

Illya and Chloe angrily separated Luvia and Shirou.

Shirou glanced around at the maids, but didn't see Miyu among them.

"Luvia, Miyu still not back?"

"Um."

Luvia nodded worriedly.

"Where... where did that child go...?"

Since the night of the festival, Miyu has never appeared in front of anyone again.

Luvia used her vast wealth to conduct a city-wide search, but to no avail.

Even when Ruby was asked, she said she couldn't contact Sapphire, as if her signal had been unilaterally blocked.

Illya said with a worried look, "Miyu... I hope she's alright..."

"Don't worry, even Miyu has her tantrums sometimes. She'll be back in a few days."

Chloe comforted her in this way.

Illya asked, puzzled, "But... why did Miyu act up that day? She was perfectly fine before watching the fireworks."

Chloe: "Wasn't it because Illya made her angry?"

Illya: "I would never make Miyu angry! If anyone should be saying that, it should be you, Kuro!"

Chloe: "Unfortunately, my only target will be Illya. As for Miyu, I've always considered her a friend."

Illya: "You're right... No! Why should I be the one you target?!"

This is when Chloe's presence is absolutely necessary.

Thanks to her frivolous personality, the team atmosphere didn't become completely terrible.
