Summary:

Happy Birthday, Misaka Mikoto!

All Misaka Mikoto wanted was to have a day of punishment with Kamijou Touma, but having Sisters argue about their own birthday could change the course of things.

Work Text:

Kamijou Touma looked around only to see four exactly the same faces before him. He was sitting at a circular table in the Underground Shopping Mall, having another one of his difficult days of punishment. 

Misaka Mikoto seemed to have enjoyed this type of encounter and constantly made silly bets that Touma always lost and had to pay with the infamous days of punishment. And that one would be like any other, where he would be dragged by the girl to go shopping and get into strange situations, if during the snack break three other Misakas hadn't joined them at the table. 

Although she liked the sisters and cared about them, Zapper didn't seem at all happy about having her date ruined by the Sisters. She was ready to electrocute them all when Misaka 13577 started.

“Misaka Mikoto's birthday is approaching and the sisters would like to congratulate her, explains Misaka after noticing Misaka' s look of disgust.”

“Birthday?” Touma questioned, looking away from sisters and looking at the girl.

“Misaka Mikoto's birthday is in a week, informs Misaka.”

“May 2nd, more precisely, complements Misaka 19090 as she tries to make herself present among her sisters.”

“If you know it’s in a week, why did you show up today?” Mikoto muttered with a grimace. 

“Because the sisters would like to hold a celebration in your honor, says Misaka 10032 as she thinks of a way to thank Mikoto for saving us.” 10032 was the Misaka who stood out the most among her sisters thanks to the heart necklace she wore hanging around her neck. 

“That’s not necessary,” she replied shyly. Mikoto had really gone to great lengths to stop the experiment and save her clones. But she hadn't done it expecting any kind of retribution. 

“But the sisters think this is important, says Misaka 13577 thinking that maybe we should buy a gift that would please Mikoto.”

“Kamijou should give a gift too, says Misaka 19090 remembering an article from a women's magazine that says girls like to receive gifts from their boyfriends.”

The other sisters stared at 19090, scolding her with their static looks while Mikoto blushed from head to toe wondering if Touma would give her a gift. 

“We should have a party, Misaka resumes, remembering that human teenagers like this type of celebration.” Misaka 10032 remembered.

“Party?! Misaka shouts as Misaka suddenly appears and jumps on Touma's neck.” The excited little girl grunted, hanging around the neck of the only boy at the table. 

The boy freed the short arms that wrapped around him and pulled the girl in front of him. The smallest of the Misakas was there, dressed in polka dots and a white shirt. 

It wasn't just her size that made her different from the others. Last Order was smiling and noisy, very different from her expressionless sisters. 

“You shouldn't be here, says Misaka 10032 while looking at the smallest of the sisters with contempt for stealing my glasses.” Her hand tightened on the table. 

“But Misaka was bored of staying at home, says Misaka as Misaka watched all the programs on television and wasn't excited about anything.” Last Order replied with a pout. “That's why Misaka came here since she noticed that the sisters were gathered, informs Misaka as Misaka when sharing the neural networks and now Misaka wants to participate in the party too, Misaka demands while she makes a bossy expression.”

“This party is not for children, Misaka counters.” 10032 actually still seemed very angry with the girl. 

“But Misaka wants to participate, complains Misaka as Misaka spins her arms.” 

“Don’t think-” But 10032 didn’t finish answering. 

“There will be no party.” Zapper interrupted, slamming her hands on the table top and scaring her clones. 

“But this is a very important day for Mikoto, Misaka highlights, looking at her with compassionate eyes." 13577 replied, who did not convey any feeling through her eyes.

“Exactly, adds Misaka 10032, trying to express her gratitude for the interruption of the project through this party.”

“I understand, but a party really isn’t necessary…” Mikoto waved her hands. 

“But we want a party, Misaka 19090 protests, thinking about how fun a party would be.”

“Why don't you have a party on your own birthday?” Touma questioned, looking at the girls.

“Although each of us was created at the same time, we had different incubation periods, Misaka explains about the unimportance of her own birth.” Misaka 13577 said. 

“The “birth” of the sisters is not important and we were never told what day we had our advent, adds Misaka, sad about not having a birthday.” Expresses Misaka 19090, melancholic within what was visible. 

Touma knew very little about the sisters: Misaka 10032 aka Imouto was the one she had the most contact with, she was usually the one who appeared at the door of his apartment to ask for help when something went wrong that could affect the Misaka Network. Misaka 19090 was the most human among them, who read magazines for girls, watched dramas and followed diets, while Misaka 13577 was the most serious and maintained a personality more similar to the original project.

“You could celebrate on May 2nd too” He suggested naively. At the same time she saw Mikoto frown and glare at him. He felt static energy forming around her. It was true that she didn't care much about birthdays and that she was happy to help her sisters, but that didn't mean she was willing to share her birthday with them. 

“Misaka would be very happy to have a day to celebrate her birthday, says Misaka blushing.” Misaka 19090 commented that she seemed happy with the resolution. 

“Misaka is also excited about this proposal, says Misaka trying to show her excitement.” Misaka 13577 shook her head to the side and clasped her hands together in an attempt to look cute.

“Why did you suggest my birthday?” Mikoto mumbled under her breath to the boy next to her at the table.

“As they are your clones I thought it would make sense…” Touma shrugged. The girl gritted her teeth and wanted to jump on the boy's neck. Why did Kamijou have to be like this?

“Misaka doesn't seem very happy with this birthday story, asks Misaka, looking at Misaka who remains quiet at the table.” Misaka 10032 had turned to Last Order, who had been seated between Imouto and Touma in a vacant chair that he had pulled from the table next to him. 

“Misaka doesn't want to celebrate her birthday that day, complains Misaka as Misaka inflates her cheeks showing her displeasure.” A shrill voice punctuated the conversation. 

“Misaka wants an exclusive day for her birthday, questions Misaka thinking about how little Misaka tends to be selfish in her decisions.” Imouto questioned.

“Misaka is not selfish, says Misaka as Misaka sticking her tongue out at Sister.” And the little girl had actually done such an action. “But Misaka would like to celebrate her birthday on another date, says Misaka as Misaka putting her fingers together sheepishly. 

“What date does Misaka think is most convenient, asks Misaka, trying to understand why you want to celebrate your birthday on a different date.” 10032 asked.

“Misaka will celebrate her birthday on August 31st, says Misaka as Misaka remembers the date.”

“Why this date, asks Misaka 10039 without understanding the reason for this choice.”

“Because that was the day I met him, says Misaka as Misaka took a serious tone.”

“He?” Questions Touma. “The same one you said you wanted to protect?” He remembered the first time she met the girl and her desire to protect a special person. Last Order just nodded. 

“He? Does that mean Misaka has a boyfriend? Misaka asks, leaning over the table and looking at the network server.” Misaka 19090 stood up, resting her hands on the table and looking at the girl.

“Don't say nonsense if Misaka had a boyfriend we would know, explains Misaka referring to the connections between the sisters.” 13577 said. 

“Misaka can control the Network's information, Misaka explains as she tries to return to the subject of her boyfriend.” 19090 retorted.

“But she's not too young to have a boyfriend, Misaka questions about the server's youthful appearance.” Misaka 10032 spoke.

“All Misakas are approximately the same age, explains Misaka when remembering that the server's development was interrupted.” Misaka 13577 explained professorially. 

“But it's unfair that she mainly has a boyfriend, complains Misaka when thinking that she doesn't have one.” Misaka 19090 replied dreamily, only to see the other sisters give her a cross look. 

Within seconds, the conversation turned from Mikoto's birthday and Last Order's possible boyfriend to the excessive love interest that Misaka 19090 had. Touma tried to calm his sisters' spirits without success. Mikoto rolled her eyes and saw her date being completely ruined, she glanced at her little version who seemed oblivious to the discussion  in that inflexible and tedious tone. .

“Thank you”, the girl said suddenly, looking at Mikoto. She was very grateful to Touma for stopping the experiments. And she was grateful to Mikoto, because if it weren't for her, Last Order and the sisters would never have existed and she would never have met Accelerator.
