It was a gloomy evening in Academy City, four close friends, Mikoto Misaka, Kuroko Shirai, Kazari Uiharu and Ruiko Saten, were all making their way back towards their homes together, after a tiring day of shopping and trying to stay out of trouble.

"Hey Uiharu, don't you think Shirai is being awfully clingy today," Saten asked as she looked to her classmate walking beside her, while the other two girls walked a little bit in-front of them.

Uiharu looked to the two girls' in-front of them and had noticed that Kuroko had done nothing but hang off of her roommate pretty much all through the day.

"Yeah I guess she does seem a little clingier than she normally is towards Misaka," Uiharu agreed as right now Kuroko was still practically hanging off of the older girl beside her, "But it doesn't seem like Misaka seems to mind much," she smiled to Saten nervously as it did look like the Railgun wasn't really talking much notice to her annoying roommate at this moment in time.

"Or maybe she's just given up on shocking her, since she's done it quite a bit today," Saten remarked as she sighed with a smile.

"Well Shirai-san's work in Judgement has been keeping her busy lately, so I guess she's probably just showing Misaka how much she missed her,"

"Yeah, but if that's true, how much more do you think Misaka-san can take of this, she seems at her breaking point to be honest," Saten stated as they both looked back to the other girls in-front of them, wondering how long it would be before the Railgun would snap.

They didn't have to wait long it seemed as Mikoto suddenly stopped and sighed heavily, while she caused the other three girls to also stop and look to her in question, "Kuroko," the Railgun whispered out in a stern voice.

"What is it Sissy?" Kuroko asked letting go of the older girl and backing up slowly, as she was a little scared of what Mikoto would do to her, she only expected her to shock her again, but she never could have guessed what the Railgun actually did next.

Saten and Uiharu were thinking the same meaning that they thought Mikoto would just shock her roommate like she has been doing a lot today, but instead the approach she actually went for was simply unthinkable as she surprised the three other girls completely.

Mikoto simply just smiled as she walked upto Kuroko and wrapped an arm around her waist, while she cupped Kuroko's cheek with her free hand, the Railgun embraced the younger girl and softly whispered out her name into her ear, causing Kuroko to shiver against her a little.

"S-S-S-S-S-Sissy?" Kuroko stuttered as she blushed deeply and looked up to her roommate nervously, while Saten and Uiharu were speechless and both looked stunned as none of them could ever see the Railgun ever doing something like this to the younger girl.

"Kuroko," Mikoto stroked Kuroko's cheek lightly, as she slowly closed her eyes and kissed the younger girl on her forehead lightly, before Kuroko swooned and collapsed against the older girl.

Saten and Uiharu stared wide-eyed, with their mouths hanging slightly agape at the surprising sight that was in-front of them. Never had Mikoto shown any affection towards her roommate, so why did she just suddenly kiss her like that?

Mikoto simply just sighed as she held Kuroko up against her so she wouldn't fall, and slowly ran a hand through her short hair, "What?" she asked as she looked to Saten and Uiharu's shocked expressions.

"Well….why'd you suddenly do something like that Misaka?" Saten asked as she shook her head and came back to her senses, while Uiharu nodded and agreed with her as they both seemed a little less stunned now.

"Well I was bored of constantly shocking her, since I've been doing it for pretty much the whole of today, so I decided to try this method out since it seems to work a lot better sometimes," the Railgun explained as Saten and Uiharu came walking over to her.

"Okay, so do you use that 'method' regularly?" Saten asked wondering why they had never seen her do something like this before now.

"I only do it under certain circumstances," Mikoto stated as she turned and smiled to her roommate, sighing again slightly as the Teleporter mumble out the word, 'Sissy' in her sleep, while a smiled formed onto her lips.

"So are we off home then?" Mikoto asked as she lifted Kuroko onto her back and smiled to the other two girls.

"….Yeah sure," Saten replied after a short pause as the two smiled back to her.

Mikoto carried Kuroko on her back, as her and the other two younger girls started to walk to their homes together while talking and laughing about random, everyday things.
