It seems that the Kagamine siblings have already accepted their persona as Hatsune Miku's friends.

They surrounded Haidou and began to explain.

"He's really powerful! He saved us when Sister Future and we were fighting against Shadow."

You said you'd save you?

"Yes, and they killed Yingping in an instant!"

Upon hearing this, Aon Kaito's expression turned somewhat strange.

He seemed somewhat wary.

"...Mr. Accelerator, is that right?"

He slowly approached the first person.

Of course, Accelerator did not show any hostile attitude.

"Thank you so much for saving my younger siblings, but... my brother told me that you seemed to have dealt with the Shadow Phantom? How did you do that?"

"Eh?"

"Wait—Kaito-nii-san!"

It seems that things have developed in a rather strange way.

"Because the only people capable of eliminating Shadow Puppet are those like our Imperial soldiers, so... I have to question your situation."

"Or perhaps...you are actually—"

Seeing that the situation seemed to be getting out of hand, Hatsune Miku quickly stepped between the two.

"Don't ask him that! He's a very important person to me, so he wouldn't have any ulterior motives!"

"An important...person?!"

In that instant, Hatsune Miku finally realized what she had said.

"Well, that——"

So the girl blushed and began to whimper softly.

"...I mean close friends, that kind of relationship."

"I see..."

Haidou seemed to have believed the prediction about the future, and that's when he finally came to his senses.

"I was indeed somewhat mistaken just now, and I'm very sorry. Please come over here and have some tea while we talk."

"Huh? Can't I drink milk tea or iced tea?"

"Didn't I tell you? You can only drink those things on your days off. Or are you going to give up the chance to drink these beverages on your days off and make it happen today?"

"Oh no—let's wait until the weekend!"

Kagamine and her brother immediately stopped saying anything, while Kaito led everyone toward the tea table in the hall.

"A very vigilant guy... It seems the structure of this era is quite extraordinary."

The city is known as the capital.

Soldiers serving the capital.

Shadow monsters roaming outside the city.

as well as.

The mysteries surrounding Hatsune Miku's past life a hundred years ago, and the enigmas left behind in this era.

Although the greatest enemy has been completely eliminated, exploring these smaller worlds afterward is still a fun activity.

Accelerator also felt somewhat involved in it.

"But I can't drag it out for too long, after all, there are still too many trivial matters waiting for me to deal with."

After thinking about the things he needed to do in other worlds, he followed them.

"Let's deal with things here first."

Chapter 846 Let's have a friendly spar?

"Then let's explain it properly first."

"Uh-huh--"

"About your encounter with Shadow, the battle with Shadow, and how you were saved by this person afterward."

"Mmm mmm mmm mmm—"

As the head of the family here, Aon Kaito wore a distressed expression.

Because his younger siblings were all lying on the table, eating the pastries served by the maids without a care for their image.

"Lian, Ling."

"Um…?"

"What's wrong, big brother?"

"If you continue to be so rude in front of our guests, you should know how I'll treat you afterwards, right?"

Thud—this time even the bowl and chopsticks in his hand fell onto the carpet.

Rin and Ren put down their food, nodded to Kaito, and sat down obediently.

"So, that means... this guy named Accelerator suddenly appeared and saved us when we and Miku were attacked by the Shadow Phantom, and defeated the Shadow Phantom in one fell swoop."

"I know that. What I'm asking about is how you were rescued? What methods were used to repel the Shadow Entity?"

"Use your hands."

"…What?"

"He just used his hand! He just casually slashed the image in half and blood splattered everywhere!"

"How can it be…"

Upon hearing what Lian said, Qingyin Haidou's first reaction was disbelief.

In his mind, only those who are divine beings have the ability to fight against shadow beings.

Moreover, under normal circumstances, killing Shadow is simply impossible.

A divine possession, as its name suggests, is a person possessed by a deity, and a shadow possession is the same, an existence possessed by shadows.

Neither the divine possession nor the shadow possession will die from simple injuries. Unless the head is cut off and the blood is drained from the body, and unless it is dealt with using a highly purifying ability, the shadow possession cannot be killed no matter what.

For ordinary humans, let alone purification, even the body of a shadow should not be able to be harmed.

but--

The expression on Haidou Observation Company's face did not reveal any hint that he was lying.

"Are you telling the truth?"

"Yes, I'm not lying at all. It's okay if Kaito asks Mirai-nee and Rin."

He looked at Rin again, who nodded with her doll, while Hatsune Miku had stated from the beginning that it was all true.

That's why.

This matter made Haidou frown even more.

"...If that's the case, then may I ask you—"

"You don't need to care about my identity."

In contrast, Accelerator did not react violently at all.

Compared to the wary Aon Kaito, Accelerator sat directly on the sofa without showing any sign of tension.

"Even if I told you, you wouldn't believe me, and even if I told you about myself, you would never understand."

"What does 'impossible to understand' mean?"

"The ability to influence actual existence based on individual reality, built upon the foundation of quantum pluralism."

—?!

Aon Kaito stood there dumbfounded. Although he could understand every word the other person said, he simply couldn't piece them together.

What...what is he saying?

"See? I never expected you to understand anyway."

Both Len and Rin wore expressions of utter incomprehension.

"You only need to know one thing: I have no interest in attacking you. I am not your enemy, and I would never have any pointless thoughts about you."

The first one spoke calmly, word by word.

"I only came here to help this girl, that's all. As for our relationship, you can just think of us as good friends, that's basically it."

No matter how much he said, these guys wouldn't understand, and Accelerator didn't intend to brainwash these people who were Hatsune Miku's relatives.

Since that's the case, let's keep everything simple.

"You mean, you want to stay by the side of the future?"

"Kaito-nii...?"

"I'm sorry, I can't do that."

Kaito's expression immediately turned serious, and his tone became very heavy.

“Future is my most important younger sister. I can’t let someone like you, with an unknown background and full of suspicion, stay by her side.”

"Seriously, Kaito-nii! He's the one who saved me, Rin, and Mirai-nee during the Shadow attack!"

"This matter is separate from the other matter; they should not be confused."

Although his behavior seems a bit straightforward, Aon Kaito of this era truly cares a lot about his younger sister.

She has the exact same personality as Kaito in modern times.

Thinking of this, Accelerator couldn't help but chuckle to himself.

"Say what you will, but I have no intention of gaining your approval in the first place."

After saying that, Accelerator stood up and put the teacup he had just taken a few sips of on the table.

"...I guess I'm just not suited for black tea."

As he watched Kaito slowly walk away from the mansion and into the courtyard, his heart was filled with complex emotions.

Why would someone like this suddenly appear next to Hatsune Miku?

"Brother Haidou".

At this moment, his dearest younger sister spoke up.

Hatsune Miku walked up to him and said with a hint of helplessness.

"Aren't you being a little too sensitive about him?"

"No, that's not true. I only said those things for your safety."

"Yes... from your perspective, he is indeed a complete stranger and a very suspicious person."

"And he seems to have a really bad personality," Hatsune Miku thought to herself with some dissatisfaction. "If he could communicate properly with his family, things wouldn't have gotten so tense."

but.

That's probably why he's known as Accelerator.

"But it shouldn't be a problem to observe it properly, right?"

Hatsune Miku then offered other suggestions.

"Instead, let him stay in our house for a few days and observe him. That should dispel your doubts."

"Let him stay...you mean stay at Aone's residence?!"

"That's right, I'll be very sad if Kaito-nii doesn't agree."

Varied--?
