Misaka Mikoto had gone off somewhere.
Kamijou was not sure why, but she had suddenly fallen into a very bad mood from the moment she had seen Misaka Imouto and that smaller version of her.
"Wait just a second. Have you forgotten whose orders you're here on!? I thought you were supposed to do whatever I told you today for that punishment game!" she had said while blushing.
Kamijou had simply replied, "Eh? I thought you just wanted that Gekota?"
For some reason, that had caused Mikoto to bite her lip a bit.
"…!! Wha-…Ah…Uuh…That's right! I don't need you anymore now that I have Gekota and Pyonko! Enough of this punishment game nonsense, you idiot!!"
That shout had been accompanied by a lightning spear, so Kamijou was currently lying collapsed in a corner of the underground mall. He had succeeded in deflecting the billion volt strike with his right hand, but it had surprised him so much that he had fallen over backwards afterwards.
(Wh-what did I do wrong…?)
Mikoto had shouted "I've had enough of you!!" and ran off somewhere, so Kamijou was left alone feeling exhausted and not entirely sure if he had truly been released from his punishment.
(First Shirai Kuroko and now Misaka Imouto. What is with today?)
Kamijou tilted his head in confusion.
The most suspicious individual had been that girl of about 10 who had been with Misaka Imouto. Her facial features had been identical to Mikoto…or rather, to Misaka Imouto, but who had she been?
(I sure hope an additional series of 20,000 Misakas wasn't made…)
That thought gave Kamijou a bit of a cold sweat, but the worst part was that it would not surprise him at all given what he knew of the city.
He sighed and said, "Ugh. I guess I'll ask Misaka Imouto later. I get the feeling ignoring that now will come back to really bite me in the ass later."
"Why are your shoulders drooping so exhaustedly? asks Misaka as Misaka clings to your back like a comforting mascot."
Just as Kamijou received an odd reply when he absentmindedly spoke his thoughts aloud, he felt some weight added to his back. All of Kamijou's hair stood on end at the round feeling on his back.
"Wh-what!? Are you a Konaki Jijii!?"
"Misaka is female and bringing up the occult in Academy City is absurd, says Misaka as Misaka presses her body up against you even more for stability. Misaka wants to make this her home base, says Misaka as Misaka informs you of her wish."
The warm mass of body heat increased in weight a bit.
The trembling feeling in Kamijou's back reached its climax.
"Wahhh!! What the hell is this!?"
As he shouted, he brought his hands behind his head, grabbed hold of the thing clinging to his back, and dragged it in front of his face like he was performing a slam dunk. What he found hanging upside down in front of him was that mysterious tiny Misaka Imouto.
(Who is this girl?)
Kamijou tilted his head in puzzlement.
The upside down girl mimicked his mannerism and tilted her head as well.
