I saw a fictional scene.

Under the illusory to pale layout, there is a young girl. She was so smart, so beautiful. She seems to have all the virtues that a woman can have, but few people understand her, and they never hear her mention herself. To all who looked at her, she had a seemingly genuine kindness. She lives like this, even if she is misunderstood by many people, she accepts everything calmly. It was so quiet, as if even time had stopped.

The sound seems to pass through time and space, and the silence is like sunrise and sunset, repeating itself constantly. Such beauty, but so lonely.

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

Mitsuki Umihara took a deep breath.

A little, a little anxious.

It was a sunny and good day with no clouds. If it was two months ago, it should be comfortable. It's summer, though.

Depending on the time of season, the same weather can give people a different feeling.

However, Haiwon is not agitated because of the hot weather.

I looked at my phone, and it was already past the end of school.

I guess, almost.

"Sorry, I waited."

He said softly in a voice like a popular virtual idol singer.

That's a foul. Who can be angry when they hear such a voice?

When I looked up, I was standing there with a super beautiful girl who was smiling apologetically and attracting the attention of everyone around her.

"Finished class? Qiongno-sensei. ”

"I hate it!"

The girl turned her head shyly, her right hand ruffling her hair, her eyes wandering.

Even for an ordinary girl, this is a very cute manner. What's more, it's a beautiful girl like her who is undoubtedly the highest level.

If there is no sense of superiority, it must be a lie. Even if Mitsuki Umihara doesn't care too much about this, he can't deny something like "Awesome, right?" There is always some mentality.

What's more, my sister is not just a rare beautiful girl. Being able to teach as a substitute teacher at Tokiwadai is not something that ordinary students can do.

Of course, he didn't mean to show off his sister.

"I'm getting used to it, but I wish I had been told earlier. I'm not very good at lecturing, so at least I should have been given more time to prepare. ”

"That's enough, don't always hope to do better, that's too much to push yourself."

Mitsuki Umihara put his hand on his sister's head. Although my sister is relatively tall among girls, Haiyuan herself is also relatively tall among boys of this age.

After a brief moment of surprise, Dome narrowed his eyes slightly.

Although it was not the first time he had done this, the touch of his long silky hair sliding between his fingers was unexpectedly wonderful, and Mitsuki Umihara was stunned for a while.

"Hmm......"

Like, I heard my sister whispering something like this. Looking down, it seemed that the dome who had suddenly come back to his senses suddenly took a step away with an embarrassed face.

Really, she didn't seem to realize how cute she was like this.

"It's like a child."

Dome said deliberately pursed his lips.

"Aren't we?"

Kaihara chuckled and looked away.

"Besides, I've never done anything I don't know if I can do. If you want to force yourself, my brother is the elder, right? ”

That is true. Most of the things that Mitsuki Umihara did made it feel as if he couldn't do it. This is something that makes the dome feel incredible, even a little envious.

However, there is no such thing. Umihara is not the kind of person who relies on himself alone, so his evaluation cannot be limited to himself. He is the kind of person who has the ability to put together all the conditions needed to solve the problem, not the kind of person who can solve the problem on his own.

At this point, the Dome did misunderstand something.

Of course, for this, even Mitsuki Kaihara himself can't say it clearly. He chuckled and changed the subject.

"Did you have a classmate you know just now?"

"For ...... Why would you know? ”

"Because of your honorifics."

Mitsuki Umihara shook his head lightly and turned his gaze forward.

As long as someone you know is present, whether the other person hears it or not, Dome will definitely change the honorific to the highest level. Sometimes, Mitsuki Kaihara also thinks she is too rigid.

Be respectful, but not rusty. This contradictory request always seems not easy. But even then, she always tries to do it as best she can. I'm afraid that no one but her can do this. However, in fact, Mitsuki Umihara believes that this is wrong.

Does she always decide what she thinks about the other person's actions? It's always that way.

She thinks too much about others, but in fact, other people's thoughts may not be the same as what she thinks. If possible, there are some people who want her to change this habit. Such an idea, Mitsuki Kaihara also lasted for nearly 2 years or so before giving up. Ironically, the reason is the same - her own thoughts may not be the same as she thinks.

The limitations of thinking are not changed by the object most of the time. In this regard, whether it is my sister or myself, it is the same.

"But ......"

Mitsuki Haihara, who was just about to say something, suddenly stopped. Because, when he saw his sister beside him, he frowned.

With a strange look that made people wonder, Dome who had thought for a moment quickened his pace.

"Wait a minute! What's going on? ”

Mitsuki Kaihara, who caught up with her in a few steps, asked. But Dome Nai's answer was very inexplicable.

"I don't know."

"Don't know?"

What's going on?

"I like, I heard some kind of noise......"

Strange answer. Haiyuan looked around left and right, and none of the passers-by present had such a reaction.

"But I didn't hear anything."

It's weird, it's weird. If anything, there is something that only she can hear...... It seems unlikely.

“…… Maybe you can't say you hear it...... But this feeling ......"

Dome Nai's expression became more and more confused.

They stopped at the side of the road, and Dome kept looking left and right, as if looking for something from the neighborhood that she cared about.

"What did you 'hear'?"

"Some kind of string sound...... Something like this......"

String tones.

It's inexplicable. Mitsuki Umihara could even be sure that there was absolutely no phenomenon that could produce string tones just now. However, he didn't think it was a delusion on the part of the dome.

So, what exactly did she hear?

Before I had time to think about it, there was a sudden sound of fireworks from somewhere.

"What was that?"

"What?"

"Fireworks?"

"Scared me."

"That's right."

Unlike what Dome said, this real explosion caught the attention of most people.

Is anyone playing a prank?

In the school city,There will indeed be some naughty students who use their abilities to prank.。 And sometimes, it's more troublesome. However, the meaning of this prank is also somewhat unclear.

If this isn't a prank, then what is?

"Brother......" Qiongno pulled the sleeve of Haihara Mitsuki's coat. Sound...... Now I can't hear it. ”

"Really?"

When she heard the strings, they couldn't hear anything. And when everyone heard it, the sound she heard disappeared.

Is it a coincidence? Still is......

If the two are indeed related, then what is this connection?

No, it's not. Until then, there's one more question to ponder.

Is this really a simple prank? If not a prank, then what would it be?

Like, try, or experiment?

And then, if the two are related, what are the commonalities?

For example...... Ability?

Ability?

Mitsuki Haihara suddenly lowered his head and looked at his sister, who still looked quite confused, in a daze.

Ability?

By the way, it seems that the ability of the electromagnetic system can sense the same type of ability with relatively little interference. So, could it be the same thing?

But when I think about it, I feel that something is not right.

The ability of the dome should be gravity. The gravitational force is so weak that it is much more difficult to distinguish than the electromagnetic force. If memory serves, she shouldn't be able to use gravitational waves to make detections right now. After all, gravitational-wave radar, even modern instruments, are far from being accurate enough to be practically applied.

The location where the explosion came from just now should be in ......

"If you can, buy me a cup of tea."

He said so.

He knew that Dome would not refuse his request. If you want to get rid of your sister, it's not a hassle for him at all.

Taking advantage of this time, Mitsuki Haihara walked to the side of artificial greenery. If I heard me correctly, the explosion just now should have come from here.

Reaching out to push aside the greenery, there was indeed a scorched mark in it.

(And so...... ）

Isn't it a prank by the mighty, but really just a simple firework? If so, it would be completely goalless. When Dome heard that voice, there was no explanation at all. Could it really be just her delusion, and the two have nothing to do with each other?

(Wait a minute, what is this?) ）

Mitsuki Umihara found that on top of the charred black traces, there seemed to be a strange layer of ash.

Reach out and pinch a small pinch and knead it gently at your fingertips, it is a very even and smooth feel. It doesn't look like charred ash, but some kind of silvery-white fine ash. The kind of ash that is closer to the fine metal that is common in industrial raw materials.

(Is it an explosive made of metal powder?) But the explosion just now doesn't look like it...... ）

Metal powders, combined with the right capabilities, can indeed cause explosions. In fact, the sister's air power named Photon after marriage should be able to do this easily. But it's not quite like that.

I made a small paper bag out of the promotional paper I had gotten earlier, and pinched up a little of the powder of the unknown body and put it into it.

His abilities don't help much in this regard. But if he wants to know the answer, he has his own way.

Again, he's not the kind of person who can solve problems on his own. However, he was able to scrape together all the conditions needed to solve the problem.

No one can compare to him in this regard.
