Part 1: https://tgcaps.net/sxs/post/power-transfer-part-1-railgun-au-tg-caption-1517
Note: Extremely shitty alternate bad ending to “Power Transfer” series. I wrote this at about the same time as part 3, but didn’t want to post it unless I had an actual continuation to the series, as this completely ruins it. I’m declaring it non-canon. You’ll just have to imagine that their fun, dysphoric misadventures continue on forever. Light NSFW.

Digging through the document, I found a note that said that the touching was “innocently, through their clothes, of course.”
As for the plot hole of why they pretended to be each other, even though it wasn't necessary – maybe they worried that they would be accused of lying to try to swap lives with each other, and made to prove their identity, which could lead to the school trying to dig into their past.
I’m sorry “Misaka”… this is all my fault. I was supposed to be the smart one, I was supposed to be the one researching and working hard behind the scenes to protect you guys while you adapted to your new lives at Tokiwadai. But I couldn’t even stay in my own stupid body… Lately, I haven’t been keeping up with Judgement for the news about that body swapping esper. I was even getting ready to join them, like I kinda always wanted to… but this body just couldn’t pass the physical exams. And whenever I saw my reflection, or heard myself speak – or even just felt my own long hair on my back – I sort of just felt useless, like we were doomed regardless of what I did… so I guess I just kinda stopped talking to them…
I only like it when he calls me “Saten” now. Though that’s what everyone’s been calling me for a while. It shouldn’t even make a difference, as I’ve already been forced to change my name before. But this time I’ve stolen it from someone else. My best friend…
The truth is, I didn’t used to think weird things about my friend Misaka. And I’m pretty sure that I would have hated the idea of taking on my friend’s identity, calling myself by his new girl name, and letting anyone have their way with his (or her) body, with me inside – much less thinking that it was the hottest thing ever. And I didn’t ever used to think that the idea of lying and betraying our friends so we could secretly have desperate make-out sessions was hot, or even an option at all…
There is only one conclusion… that this isn’t what we wanted. If we assume that Shokuhou not only has the power to control minds in the moment, but can also make you forget that it happened… Did we do something to make her mad, and now she’s having her revenge? Or is she just making us play out a weird fantasy? Is she just gonna leave us like this? But why was she always so interested in teasing us in the first place? …And didn’t she transfer to this school just before we did…?
Heh, I’ve figured it all out. Gotta keep it to myself for now, my friends would just mess up and tip her off, then we’d really be screwed. But… Awww, is this really not gonna feel good anymore? I can’t believe that… But I can’t betray Misaka, I can’t force him to keep doing this… Tomorrow for sure…
