"Something from before again?"

Mikoto Misaka takes out a can of drink from the vending machine.

"This is the fifth case. As before, the explosion itself was small and did not cause any injuries. But ......"

"It's really hard to laugh at as a happy criminal. So, what about the clues about the suspect? ”

"Yesterday, I finally found a clue. Sister, have you heard of Graviton? (Note: The name "Void Blast" is not used here, but the original English text is directly used, and you should be able to imagine the reason.) ）

“Graviton？” Mikoto Misaka thought for a moment, "Ah, it's a graviton, right?" Not long ago, Kaihara-san also talked about it. ”

"In either case, a large graviton acceleration was detected by satellite prior to the explosion." Shirai knocked on the aluminum can in Mikoto's hand, "If the aluminum can is used as a base point to accelerate the graviton at an explosive speed, and then spread around instantly, the aluminum can will look like a bomb, that's the principle." ”

"Why aluminum cans?"

"Who knows?"

"What does anyone know...... But since that's the case, you know that this is what the powerful do, right? In that case, just check the 'library' of the academy city, isn't it? Isn't all student ability data documented? ”

Kuroko Shirai sighed.

"This has certainly been searched. If the ability replied was Synchrotron, and the ability was enough to turn an aluminum can into a bomb, only one LV.4 student would be eligible. ”

"So that person is the suspect, right?"

"But she has an alibi," Kuroko Shirai interrupted Mikoto, "that person has been hospitalized, and it is impossible to cause this chain of incidents." ”

"I see, so I can't solve it."

"There shouldn't be any gaps in the data in the library."

"Ah, maybe there's someone else who hasn't documented the ability or something." Mikoto Misaka suddenly became excited, "Then, I'll also go and help find the suspect......"

"No need!"

Before she could finish speaking, Shirai immediately vetoed.

"Sister, did you just think, 'This might be fun, and I can try my hand depending on the strength of my opponent'?"

"How could that kind of thing ......"

Mai Koto tilted her head to the side and said with obvious lack of confidence.

"It's useless to play stupid! I've seen through the sunspots a long time ago. Really, I told you a long time ago, my sister is also an ordinary person, and the activities to maintain law and order are ......."

"Just leave it to the Discipline Commissioner, right? I see. ”

That said, Mai Trin doesn't look like she's willing to sell it.

"It would be a mistake to think that you can be qualified as a member of the Discipline Committee with unserious curiosity and interest. Really, when will my sister learn to be like Kaihara-san? ”

"So, I wasn't going to do that......"

Kuroko Shirai held up a finger in front of Mikoto Misaka.

"Then please swear by here and now. First, we must not wade into the troubled waters of this incident casually. ”

"Wait! What is this? Such unilateral demands ......"

"Second!" Ignoring her words, Shirai then raised a second finger, "Even if you are unfortunate enough to be involved in the incident, you will act strictly alone and wait for the arrival of the Discipline Commissioner." ”

"That's because the incident was resolved before you came......"

"Third! Shorts are not allowed under skirts. ”

"It's okay with this!"

Of course, it doesn't matter, it's just that it is revenge for what Mai Trin said before, implying that the members of the Discipline Committee always come to this kind of meaning after the fact. However, it is undeniable that there are some personal preferences of Kuroko Shirai. Shirai Kuroko is the type that can pull out a bunch of inexplicable truths.

"I take this opportunity to re-examine myself in terms of clothing and other attitudes towards life. Speaking of which, my sister is very lacking in the consciousness of being the trump card of Tokiwatai, and Kuroko is also very worried. ”

"Kaihara-san's ...... not wearing a yet"

For Shirai, this sentence is no different from a bolt from the blue.

"Sister...... Sister-sama...... You're ...... I actually peeked into the bottom of Kaihara-san's skirt......"

"Huh? Hey? No, it's not! You see, isn't there a gym class? ”

Mikoto quickly shook her head in denial, but Shirai froze there completely as if her whole body was white.

_

"So I've said it, anyway, I'll always know when I change clothes in gym class, right?"

"Whew, it really scared me to death, I thought my sister had changed her mind...... Pain Pain Pain Pain !! ”

"It seems that you should take this opportunity to re-examine yourself from various attitudes towards life......"

Mikoto tugged at Shirai's ear, and although Shirai was crying out in pain, he looked like he was quite happy. Mikoto, who realized that the other party had no intention of changing her mind, let go in boredom.

"Sister, although it is said that Kaihara-san is worth learning from, this is not at all. She did it because ......"

"Because she has the ability to fly, she has to do this, right? It's not that I don't know that. Hey? Kuroko you ...... What's wrong? ”

Shirai Kuroko suddenly stopped her daily noise and stood there quietly frowning. Mikoto Misaka knew that this was her performance when she was thinking about business. Although she is extremely unreliable on weekdays, she is quite serious when she should be serious.

Just like the other students in Tokiwadai,Although there are all kinds of problems,But the reason why they are the object of reverence for the students of Gakuen City,It's not because of superficial aspects such as their family background and appearance.,But because they're really worthy of being looked forward to.。 This is true even in the very outrageous Shirai Kuroko.

If it weren't for this, with Shirai Kuroko's usual performance, how could he be accepted by Tokiwadai?

After a moment, she looked up with a serious expression.

"Sister, it seems that we have forgotten a very important person."

"What?"

Mikoto Misaka didn't react for a while.

"Graviton, this concept is a graviton, right?"

"Ah, yes. What's wrong? ”

"Sister-sama, what is Kaihara-san's ability?"

“……”

Mikoto Misaka froze suddenly.

"You...... You mean...... Kaihara-san? Hahaha...... This, it's simply impossible, right? ”

"But,As the No. 1 gravitational ability in the school city,She should be able to do such a thing, right?"

"It's too unlikely, you see, it's Kaihara-san......"

"I know!" Shirai Kuroko raised her voice, "It's the model student of Tokiwadai, Kaihara-san......"

She turned, as if taking a deep breath, and stepped away.

"Y-Where are you going?"

"Go to the branch to find out if there are any relevant clues."

"I said it wasn't possible......"

"Sister-sama......" Kuroko Shirai turned her head, "Have you ever heard this?" My thinking is based on the assumption that when you have ruled out all impossible conclusions, what remains, no matter how bizarre, must be facts. ’”

"But you know that's impossible, right?"

"Yes, I don't believe it. Sister, you know that she is even my lifesaver. But ......," Shirai paused, "I said that too, right?" Discipline committee members are not just casual and competent......"

Mikoto Misaka was speechless.

"So, I'll go too, no problem, right?"

Shirai Kuroko looked at her for a long time and nodded.

_

"Ah, Shirai-san. Hey? Is Misaka-san, too? ”

Among the 177 branches of the Discipline Discipline Commission, Chu Chun Ornament has been called over in advance.

"What's going on with Shirai? Why were patrols canceled? ”

There is an older senior sister in the branch, which is also a consistent feature of the Discipline Inspection Committee branch.

"Something, Sister Gufa. I need some time, and the help of early spring. ”

Once Kuroko Shirai behaves seriously, he thinks that there must be something important. The older senior looked behind her.

"Who is this?"

"Ah, my name is Mikoto Misaka."

"Misaka...... Mai Trin? Is that the 'super electromagnetic cannon'? ”

"Let's wait a minute, Sister Gufa. In early spring, I want to check in on the monitoring of the location of the Graviton incident in the past two days, is that okay? ”

"This ...... Technically there is no problem, but you need to apply for ......"

"Then hurry up, please."

Shirai Kuroko rarely speaks in such a tone. Hearing her say this, there must be something important about Gufa's natural consciousness, and she nodded.

About 10 minutes later, the consent was issued.

"So fast?"

Mikoto Misaka didn't expect that the Discipline Committee member could be so efficient. In her impression, aren't all the members of the Discipline Committee the type that only appear after the fact?

"Because it's a bit serious." Gufa next to him replied. "At first, it was an empty can of garbage cans, but recently it is common to find dolls and children's bags in aluminum."

"If it's a prank, that's too much...... That ......"

"Gufa Meiwei."

"Sister Gufa?"

"But what did Shirai-san find?"

“……”

Mikoto Misaka didn't know what to say, she couldn't say that they were suspicious of their classmates.

"It's only been approved for nearly three days, is it okay?"

Hatsuharu asked as he tapped on his keyboard.

"Hmm." Kuroko Shirai stretched out her hand to support her chin, "Although it is a little insufficient...... It's ok. ”

"But what can you see?"

"I don't know yet, I hope my judgment is wrong......"

"Huh?"

The early spring was a little confusing. Why does Shirai say that hope is wrong?

"Wait a minute! This picture ...... Pull it closer. ”

Following the direction Shirai pointed, after zooming in on the picture, a figure clearly appeared in the picture.

The figure of a Tokiwadai student.

"This is...... Umihara-san? ”

Mikoto Misaka didn't pay much attention to the screen, but Hatsuharu's words surprised her.

"It's a coincidence, right? Shirai-san? ”

Early spring seems to have sensed something.

“…… Check out the next bombing. ”

Shirai frowned, she was in no mood to explain at this time.

Soon, another video appeared on the screen.

“…… Pause and zoom in on the left side of the camera. ”

"No...... No way? ”

Hatsuharu Kaori couldn't help but scream.

In the position that Shirai is referring to, there is still the figure of Umihara Dono.

"This ...... It's a coincidence, right? ”

Hatsuharu turned his head and looked at Shirai incredulously.

“…… Continue ......"

Continuously query all blasting events in the last three days. As a result, all event surveillance has revealed traces of Dome at the scene.

"I see...... I can see why you did it. Gufa Meiwei nodded. What are that classmate's abilities? ”

"It's the gravitational level of domination."

"Gravitational ...... I see, is this still possible......"

"But it can't be, right? That's Kaihara-san! ”

Hatsuharu Ori shouted on the spot.

Mikoto Misaka and Kuroko Shirai couldn't give her any answers. They couldn't believe it either, but the probability was ...... If this is a coincidence, then the probability should be about the same as "impossible".

(Sea...... Haiwon? ）

Gufa Meiwei was stunned.

This surname, she remembers.

It was a name that had almost become a story in another time segment.

The bridge that had disappeared between the past and the present seemed to suddenly become clear with the name.
