A certain scientific Saten Ruiko

"This is not the first time that I have wondered whether this guy was created from my DNA..."

Misaka Mikoto looked at Misaka No. 9982, who was walking in front and staring at a butterfly with a silly look on her face, and couldn't help but complain to Saten Ruiko who was walking beside her.

"I think it's quite cute." Saten Ruiko smiled, such a cute Misaka sister is so cute, isn't it?

"Oh~ I really don't understand you..." Misaka Mikoto sighed helplessly, then walked up to the giggling Misaka sister and stretched out her hand to drive the butterfly away, and then said helplessly: "I said, can you please stop showing such a silly expression on my face?"

"I want to eat ice cream. Misaka pointed at the ice cream cart over there and looked at my sister longingly, hoping to impress her to buy ice cream for Misaka."

"Hey~ can't you just listen to me?" Misaka Mikoto started dancing angrily.

"Pfft~"

Saten Ruiko couldn't hold it back and finally laughed, but when she met Misaka Mikoto's gloomy gaze, she quickly covered her mouth and suppressed her face until her face turned red.

"Oh~ forget it, I'm going to buy ice cream. Saten, please watch this sister here and don't let her run around."

Seeing her friend's expression of wanting to laugh but not daring to laugh, Misaka Mikoto finally sighed and waved her hand and walked towards the ice cream truck on the roadside.

"Hahaha..."

After Misaka Mikoto walked out, Saten Ruiko finally couldn't hold back her laughter. This made Misaka Mikoto, who had not walked far away, grit her teeth angrily, stamp her feet to vent her anger, and then walked away quickly. go out.

"What are you laughing at? Misaka carefully observed Saiko-chan who didn't know why she was laughing, and secretly complained in her heart that you are so stupid."

"Forehead..."

Saten Ruiko, who was still laughing at Misaka Mikoto for being beaten by Misaka's sister, couldn't laugh after hearing what she said. The corner of her mouth twitched slightly and she coughed twice, but she said seriously.

"Ahem~ I'm just releasing an emotion called happiness. After all, your sister was so funny just now."

"I don't understand. Misaka is trying to understand." Misaka's sister tilted her head cutely.

"Hehe~ It doesn't matter if you don't understand. You will understand gradually in the future~" Saten Ruiko pinched Misaka's sister's cheek and said with a smile. It seems that even if the emotional program is injected into these sisters, they still need to learn slowly. To generate and understand these feelings, after all, nothing is done in one fell swoop, so don’t rush and take your time.

捏~

"Well?"

Saten Ruiko was stunned. She didn't expect Misaka sister to pinch her nose in turn.

"If you pinch Misaka, Misaka will pinch you too, do, Misaka will never suffer." Sister Misaka pinched Saten Ruiko's nose cutely and spoke without any emotion, which surprised Saten Ruiko. words.

"I'll be back...Hey~ what are you doing?"

Misaka Mikoto shouted speechlessly while holding ice cream in both hands and looking at the two people who were pinching each other's faces and noses respectively.

Hearing the sound, Saten Ruiko rubbed Misaka's face hard again and let go. Of course, she was not spared and was rubbed hard on the face by Misaka's sister who would not suffer any loss before being let go.

"It's ice cream, thank you, sister."

Misaka sister took an ice cream from Misaka Mikoto's hand and started eating it cutely.

"It's rich but not greasy, with a refreshing and sweet aftertaste. Needless to say, we use high-grade milk, and we also use fine Japanese sugar to achieve this flavor. The cone is based on the pie crust of crushed biscuits. It's really good. Eat, do, Misaka praised without hesitation."

"I said, what were you doing with her just now?" Misaka Mikoto handed a piece of ice cream to Saten Ruiko and asked speechlessly.

"Well, um, I couldn't help but pinch her because she was too cute. I didn't expect that she was a master who would not suffer any loss." Saten Ruiko didn't hide anything but explained everything. Let’s talk about what happened.

"You are so childish..." Misaka Mikoto complained speechlessly. She just stuck out her tongue to take a sip of ice cream, but it was too late.

"Huh?" Stunned for a moment, Misaka Mikoto looked down and saw that only the ice cream cone in her hand was left. She turned to look at Saten Ruiko's, twitched the corner of her mouth, and then looked at the suspect.

"What's the matter? Misaka enjoyed the refreshing aftertaste of the chocolate mint and pretended not to know." Sister Misaka turned her head away, with some ice cream residue in the corner of her mouth, pretending to be cute and unaware.

"Hey~ you said it all!" Misaka Mikoto stamped her foot, but seeing the other party like this, she had no choice but to sigh helplessly, "Oh~ forget it, let's take you back to the hospital first."

Saten Ruiko looked at the cone roll in her hand and was silent for a while, then quickly ate it in three or two mouthfuls. Then she smiled and said: "Come on, Misakas, let's leave quickly, otherwise it will get dark later." Oh~"

"Misaka wants to drink black tea. She feels cold after just eating ice cream, so she wants to drink black tea. Do, Misaka asked casually."

"what?"

Misaka Mikoto and Saten Ruiko were stunned, obviously they didn't follow each other's thinking.

"Don't look at me like this, but I'm actually very picky about black tea. Do, Misaka raised the bar in advance." Sister Misaka looked at the two of them expressionlessly.

"By the way, I'd like to order milk tea. Do, Misaka has already ordered it in advance."

"Ah~ I really can't stand it anymore. I'm going back first, and I'll leave her to you Saten." Misaka Mikoto finally shouted unbearably, then left an angry sentence and left quickly. .

"What's wrong, onee-sama? Do, Misaka said she was very surprised." However, Misaka's sister didn't realize that the other party was angry with her, and she turned to look at Saten Ruiko in a cute way.

"Um...it's okay. She has a bad temper during her menstrual period. I'll take you to a teahouse nearby." Saten Ruiko casually gave a reason, then put her arms around Misaka's sister's shoulders and moved toward Misaka Mikoto. Go in the opposite direction.

......

"What kind of tea is this? Do, Misaka asked pretending not to care, feeling the sweetness of milk and vanilla in her mouth." After Misaka finished speaking, she continued to sip the tea she was holding.

"This is called Jinxuan tea. It is a specialty tea in the Ali region. It is famous for its milk and vanilla-like sweetness. It is a very delicious tea." Saten Ruiko smiled and gave Misaka a little science knowledge about this tea. Shokuhou Misaki often invited her to drink it. At first, she thought it was milk, but when she drank it, she realized that it was tea, and it was quite delicious, so she remembered it. This time it was just right. Invite Miss Misaka to drink.

"Well, Jinxuan tea. Do, Misaka secretly wrote down the name, thinking that when she goes back, she will ask the signal tower to ask for Accelerator's bank card, and then buy a lot of it and go back and drink it slowly." Sister Misaka was drinking tea. He muttered and began to plot Accelerator's bank card.

Saten Ruiko just smiled and looked at the cute and sinister look of Misaka sister, without saying anything.

"One more drink. do Misaka requested without politeness."

Looking at the empty cup handed to him, Saten Ruiko took it with some amusement and made another cup for him.

It was already after eight o'clock in the evening after she sent the sister who had broken Misaka Mikoto's defense back to the hospital. Saten Ruiko stretched herself on the way back to the dormitory.

"Hmm~~~Huh~ Today has passed before I knew it."
