A certain scientific Saten Ruiko

Tokiwadai Middle School.

Girls in winter uniforms walked down the corridor, greeting each other politely.

"Shirai-san, Shirai-san..."

"Ok?"

Shirai Kuroko, who had become like a walking corpse because she hadn't seen her elder sister for several hours, was finally awakened by the calls.

"Shirai-san, what's wrong with you? You seemed listless during class. Are you feeling unwell?"

Wannei Kinuho and Awabu Manbin looked at Shirai Kuroko with some concern. The three of them were classmates and their seats were relatively close. The two of them had noticed Shirai Kuroko's abnormality a long time ago, so they caught up with her at this time.

"Do you need us to take you to the infirmary?"

"Ah...thank you, I'm not feeling unwell."

In response to her classmates' concern, Shirai Kuroko smiled and waved her hand. It must be said that except when facing Misaka Mikoto, Shirai Kuroko's ladylike side makes it difficult for people to imagine her attitude towards Misaka Mikoto. It is no wonder that in the summer of July, the two of them showed expressions of being shattered.

"Is that so? That's great."

"Since Shirai-san isn't feeling unwell, why don't we go have some tea and invite Married-san to join us."

"Uh... no... no thanks. I still have things to do as a discipline committee member, so I won't go. Thank you for inviting me." When Shirai Kuroko heard the name of post-marriage Mitsuko, the corners of her mouth twitched unconsciously. It's not that she hated the other person, but she was really not good at dealing with that kind of guy.

"Is that so? That's a shame. Then, Shirai-san, we'll take our leave now."

"See you."

Watching the two leave, the smile on Shirai Kuroko's face instantly collapsed and her whole body drooped.

"Onee-sama is not here... I don't know where Ruiko went, and Hatsuharu is still in the research institute, so I'm the only one left..."

Muttering to himself, Shirai Kuroko was moved almost aimlessly by his own feet, wherever he went, following his muscle memory, he arrived at the office of the third branch of the Discipline Committee of Tokiwadai Junior High School.

"We're here... isn't Komaki here either?" Shirai Kuroko sat in her seat and picked up the document next to her and started reading it with some boredom.

"Ok?"

Halfway through reading, Shirai Kuroko became serious.

"It's really too much for someone to do such a prank."

However, after seeing the end, Shirai Kuroko sighed again. It turned out that at the very end, the case had been signed by Komaki-san to close the case.

That person was a student of Shidaezakura School. Because he couldn't compete with a classmate from Tokiwadai in terms of love, he secretly attacked and knocked the other person out on the way, and also drew dark circles under the eyes and thick eyebrows on the other person's face with the kind of ink that can't be washed off within a week...

Although Shirai Kuroko felt that this was too much, her mind inexplicably thought of the incident with the Fantasy Hand. When she thought of Mitsuko's eyebrows and Crayon Shin-chan-like eyebrows after marriage, she couldn't help but curl up the corners of her mouth. It was clearly an expression of gloating.

But the next moment he retracted his gaze, showing a bored expression again, with one hand supporting the side of his face.

"Where is my elder sister?"

Suddenly, Shirai Kuroko stood up abruptly.

"Oh, by the way, onee-sama might have gone to the hospital to visit her sisters. It's really unbelievable that she didn't even invite me, Kuroko, to visit her sisters."

"Well, let me think, what should I buy for my sisters?"

.......

Misaka suddenly shuddered, which made Misaka No. 9982 beside her turn her head curiously.

"What's wrong with you? Do, Misaka asked with concern."

"Suddenly I felt a chill. Do, Misaka rubbed her arms and said with lingering fear."

"Could it be a cold? Do, Misaka speculated."

"No, Misaka feels that something terrible is coming. Do, Misaka, who also felt the chill, said so."

"Horrible thing? Could it be Kuroko? Do, Misaka shuddered when she thought of that perverted woman."

"What should we do? Do, Misaka asked as if facing a great enemy."

"We are definitely no match for the enemy head-on, so Misaka thinks it's better for us to run first. Do, Misaka suggested so seriously."

"Misaka knows that a new dessert shop has opened in the shopping street. Anyone want to join us? Do, Misaka suggested."

"Since the Misakas all look the same, only three Misakas can go out together, so the Misaka will take up a spot first. Do, Misaka said a lot of words to divert attention, and grabbed a spot before all the Misakas could react."

"This leaves only one. Misaka is number 9982, the oldest here, so let this Misaka take the last spot. Do, Misaka got the last spot by virtue of being the oldest."

"Too cunning. In this case, we have no choice but to go somewhere else. Although Misaka really wants to snatch it, time is running out and she has no choice but to give up."

The Misaka sisters developed a series of evacuation plans on how to avoid Shirai Kuroko, and it was quite intense.

"The plan has been decided, let's start the action. Do," Misaka gave the order seriously.

"Yes! Do, Misaka answered seriously."

At this moment, the Misaka sisters demonstrated their strict discipline (which only exists when dealing with Kuroko). Afterwards, the Misaka sisters left the hospital in groups of three or two, whether to go to a dessert shop or to hang out, but at least they did not stay in this "dangerous" place, the hospital.

Thirty minutes later.

Swish!

Shirai Kuroko's figure appeared at the entrance of the hospital, holding the drinks and small cakes that she had carefully prepared.

After completing the usual procedures, Shirai Kuroko happily pushed open the doors of her sisters' exclusive rooms.

"Sisters, your sister Heizi is here to see you...?"

"Ah? Where are the people?"

Halfway through her words, Shirai Kuroko realized that none of the cute sisters who looked exactly like their elder sister were there, so the smile on her face disappeared.

"Are we playing in the backyard?"

Shirai Kuroko frowned and guessed, then walked to the window, from where he could see the place where the sisters often played, but he still didn't see any of the Misaka sisters, which made Shirai Kuroko even more puzzled.

"Strange, why aren't any of them here? Are they recuperating? But this is not the right time, and the sisters' bodies have almost recovered, so they don't need to take nutritional meals anymore..."
