Misaka Mikoto was inside a convenience store.
She stood in the corner with rain gear.
"Hmm…Too small," she muttered while looking at a cheap plastic umbrella.
With that sort of umbrella, the ones that were not too bulky were popular, but she thought she would get pretty wet if she used one that small.
She looked outside the large window to see the pitch black nighttime scenery. Fairly large raindrops were hitting the glass.
After defeating him during the Daihaseisai, Misaka Mikoto had gained the right to give Kamijou Touma a punishment. But that punishment had been cut short, so she had been searching for Kamijou once more. However…
"Why did it have to start raining?"
Her gaze dropped to the paper bag from a cell phone company that she held with her school bag.
(I don't want the Gekota and Pyonko straps to get wet.)
As Mikoto groaned over that issue, her phone suddenly rang. She grabbed it in annoyance.
It displayed the number of her underclassman Shirai Kuroko.
"Onee-samaaa."
"What is it, Kuroko?"
"I have Judgment work, so I won't be able to return to the dorm. Can you pass that on to that annoying dorm supervisor? The curfew has passed after all."
"Um, I'm actually at a convenience store."
"Gyahh!?" was Shirai's very unladylike response.
Another quieter and more distant voice could be heard coming from the phone's speaker.
"Huh? Shirai-san, could you not contact Misaka-san?"
That was likely Uiharu Kazari, Shirai's fellow Judgment member.
That meant Shirai was likely in her Judgment branch office.
"Shut up. Onee-sama is out, so she cannot contact our dorm supervisor. But this is not good. The curfew extension process requires a document to be submitted and the dorm supervisor is not answering the phone. At this rate, both of us will receive a demerit."
"Hehh. By the way, why is Misaka-san breaking curfew tonight?"
"!?"
Mikoto heard a gasp and then a dull creaking sound. Shirai was likely violently squeezing the phone in her grip.
Shirai Kuroko asked, "O-onee-sama, do not tell me you are on a nighttime date with that rotten ape! Curse him! Enjoying the rainy night scenery is quite a refined choice!!"
"No, you damn idiot!!" shouted back Mikoto without thinking.
However, Shirai did not seem to be listening.
"Kh. This cannot stand. It is my duty to protect onee-sama's chastity!!"
"D-don't say chastity so loudly!"
"Then to be more specific…"
"Don't be!!" shouted Mikoto with her face beet red, but Shirai was past the point of listening.
Words flew from the speaker like bullets from a machine gun.
"At any rate, I will be heading there. I will definitely go there. Where are you, onee-sama? You use the GPS service, so just email me your confirmation code and-…"
"You can't."
Uiharu's one short statement caused Shirai's machine gun to jam.
Uiharu went on to say, "Look, we have barely made any progress on this bundle of office files, this pile of financial files, or this mountain range of instruction files. Shirai-san, we really are going to have spend all night on this. I bought bentos for dinner, so please do not set one foot outside of this office. No heading out for a bath either."
"Gaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhhhhhhhhhh!!"
"H-hgyahh!? Shirai-san, Shirai-san!!"
Mikoto heard sounds of a struggle over the phone.
She removed the phone from her ear a bit and said, "Um, I'm going to hang up."
Instead of the crazed Shirai, Uiharu answered.
"Oh, okay. I will keep Shirai-san here, so…um…good luck!!"
"I'm not on a date!!" shouted back Mikoto as loudly as she could, but it did not seem to reach the girls on the other side.
The sounds of a struggle continued for a bit and then the connection ended.
