Reincarnated in another world, I also want to be invincible at the beginning

Miyu is Illya's best friend!

So from now on, Sister Si is Illya's sister!

"As expected of my Master, he actually wants to take in both sisters!"

Ruby cheered on the side.

Illya retorted with a blush.

"No, I don't think that way about Miyu!"

"Oh? Ruby, I didn't say anything. What kind of idea is that?"

"Ruby, shut up!"

Illya grabbed the ruby ​​and threw it out of the window.

"Miyu? That kid."

Luvia, who was standing aside, seemed to be thinking about something.

She knew that Miyu was the child who was wandering in the park.

The child’s identity information was forged by Bafansi.

It's a little guy with a very mysterious origin.

Even she hadn't figured out Miyu's true identity.

"Isn't that the transfer student you mentioned before, Illya?"

"Yes, now Miyu and I are good friends."

"No, to be honest, I still feel that it makes no sense and I can't understand what the connection is."

Toosaka Rin pressed her forehead.

Illya, it doesn't matter what your relationship with Miyu is.

The important thing is, how are you related to Bafansi?

It's impossible that the little monster is a sister-con?

No, if the little monster really has a sister complex, then the first person to be on guard against is you, Illya.

"Why do you care so much? Just decide whether to change it or not."

"Change!"

"Then I'll go to school tomorrow and give these two cards to Miyu."

Illya put Archer and Lancer's cards into the card holder that Yabinji had given her before, and then gave the original four cards in the card holder to Toosaka Rin and Luvia.

However, after looking at each other, Toosaka Rin and Luvia shook their heads to indicate that they didn't need it.

"Illya, I'll leave the card with you."

"That's right. After all, you are the owner of the ruby ​​now."

Ruby just then flew back from below.

Illya heard the two of them say this and nodded obediently.

"Ok."

"Now that we have discussed this matter, let's get back to business."

Toosaka Rin and Luvia's expressions suddenly became serious.

Toosaka Rin even said: "I remember I have already explained the details in the letter, Illya, do you need me to explain it to you again?"

"Well, I actually don't quite understand what you wrote in the letter, Rin."

Illya scratched her head in embarrassment.

What kind of ground veins and what kind of pollution.

In short, she had absolutely no idea what these professional terms were.

Even though Ruby had explained it to her, she didn't really understand.

Toosaka Rin couldn't help but twitch the corners of her mouth twice.

"Forget it. I knew it would be like this, so I'm mentally prepared."

"Ha ha ha ha......"

Illya smiled sheepishly.

"Well, to put it simply, there is a card hidden in Fuyuki City. It is the eighth card that should not have existed. Because of this card, after all the cards were collected, the ground veins of Fuyuki City that should have been restored were not restored, and the scope of pollution continued to expand. If this card is left alone, the spiritual vein system of Fuyuki City will definitely be affected. If it is not handled properly, it is not impossible that the entire Fuyuki City will become a dangerous area of ​​abnormal phenomena."

"Uh......"

"Illya, you don't need to consider the consequences of failure, because no matter what, we will definitely recover the eighth card!"

"Oh."

"Then let's decide on a time to go to the management area of ​​the leyline to explore."

"Rin, didn't you say that your Tohsaka family is the manager?"

"...Illya, are you looking for a fight? How could I do something like this in my house? If my house gets bombed, will you compensate me?"

......

In the morning, Miyu came to school.

It didn't take long.

Illya also came to school riding Shirou Emiya's bicycle.

When Miyu was hesitating about how to greet Illya, Illya had already come over.

"Good morning, Miyu."

Illya said, placing a card sleeve on Miyu's desk.

Miyu's pupils trembled, and it took her a while to calm down. She looked at Illya expressionlessly.

"Illya, what is this?"

"Oh, this is for Sister Si. Please, Miyu, pass it on to me."

"..."

Miyu hesitated for a moment.

"I understand."

She carefully put the card holder away and put it in her pocket.

When Illya saw this scene, she suddenly wanted to regret it.

"Well, how about I just give it to Sister Si myself?"

Miyu heard this and stared at Illya expressionlessly.

"..."

You must be making fun of me, Illya.

Do you know how difficult it is for me to make this decision?

I have already made a decision, and you want to go back on your word?

Miyu didn't move.

Seeing this, Illya's smile froze. Did she seem to have made Miyu angry just now?

"Um, Miyu, what is the relationship between you and Sister Si?"

Illya thought about how Miyu looked when she met Yabeshi yesterday, and she felt like something was wrong.

Although she didn't want to think so, she couldn't help but think about it.

Is it possible that Miyu was bullied by Sister Tsukasa at home?

"..."

Miyu heard this question.

He looked at Illya with a weird look.

Then, Illya heard Miyu ask, "Illya, how do you know my sister?"

"Uh, well, uh..."

Illya hesitated, unable to think of any good excuse.

She didn't know yet that Miyu was also an insider in the magic world.

But she soon remembered that her brother seemed to know Sister Si, so she thought of a solution quickly.

“My brother introduced me

I know him."

"elder brother?"

Miyu was stunned for a moment.

How can it be?

Could this matter be related to my brother?

Wait, that’s not right. The brother in this world is not her brother.

Illya, who was standing by, saw Miyu's performance and immediately stared at Miyu with a vigilant look on her face.

Something is wrong. Every time Miyu talks about her brother, she gets very emotional.

Sure enough, it was because...

Is Sister Si very mean to Miyu?

That's why every time Miyu came to her house and saw herself interacting with her brother, she always had a look of longing on her face.

This is because Miyu is envious of having a good brother.

Because Sister Si is a bad sister!

Illya felt as if she was possessed by Sherlock Holmes at this moment.

She felt she knew the truth.

I didn’t expect that, Sister Si, you turned out to be a bad sister!

Bafan Si, who had just sent Meiyou to the junior high school, sensed a faint malicious intent.

Because the malicious intent was so weak, Bafansi glanced at the classmates around him and didn't take it seriously.

"If it was... Shirou-nii who introduced you, then forget it."

"wrong!"

Illya rushed forward and grabbed Miyu's shoulders.

Miyuu was a little flustered when she saw Illya's serious expression.

No, Illya, I don't want to snatch Brother Shirou from you.

Miyu opened her mouth and then closed it tightly.

Illya looked at Miyu seriously.

"Miyu, you must be hiding something from me!"

Miyu quickly shook her head.

No, I really don’t think so!

I just can't control myself sometimes.

Miyu was extremely nervous.

How should she explain this to Illya? Although she really doesn't want to compete with Illya for her brother, every time she sees brother Shirou, she can't control her behavior.

Even though she knew that was not her brother.
