THIS DREAM CONTAINS ADULT SUBJECTS AND SITUATIONS
I am reading a manga book. As I read it, I somehow get into the story and see it moving in real time, and I'm the protagonist. The viewpoint would keep mixing back and forth between me as a reader and as the character. I'm flipping the pages of the manga, which is a translated version, which has also been mirrored so it follow the left-to-right numbering, rather than the original right-to-left. I flip a few pages and stop in the middle of a fight. Things start to mix up. I'm the main character of the story, a rather resourceful fighter/ninja with long black hair. I'm fighting along with a girl who is a companion of mine against a terrorist, who has this big plans about killing a lot of people.

It seems the terrorist was set on using some kind of virus or substance in the air. It turns out that it could easily get into people's bodies, and if they breathed 7 (milligrams?) of it, there would be heavy side-effects, and 8 would finally mean death. For some reason, only 8 could actually kill, though 7 was bad enough. (Apparently, the whole thing about the number 8 comes from me reading the first Discworld book). In the midst of this whole mess, a new threat had shown up: there was this black-haired girl who was, apparently along with some troops, invading and wrecking havoc in an urban area.

This girl also had access to a really advanced technology - she had an armor that covered parts of her body. At first look it seemed to be made of some kind of matte white sludge, but I noticed it could actually harden and protect her from explosions and bullets. The armor would change density and shape quickly, transforming between different kinds of protections and weapons at will. Of course, for it to work properly it meant she was basically naked, though the armor covered her crotch and che. She came on attacking the city, destroying several buildings. The army intervened, but that didn't help - her armor could, for example, transform her arm parts on blades, which would cut through buildings easily. Due to her violence (apparently we did try to reason with her, to no avail), we figured she worked for the terrorist.

Luckily for us, I also had a similar armor! We started battling one-on-one on a huge, epic duel I have no memory of. The big climax was when I caused a big explosion. Her armor had to move away to protect her from harm, so I seized the opportunity: I held her and penetrated her as the armor moved away from her crotch. Yes, apparently I figured sex (or rather, maybe rape?) was a good plan to calm her down. She was surprised, but also surprisingly rather willing. We engaged in sex (in the middle of the battlefield, yes). Later, she'd turn into my ally, and we'd find out that she actually didn't work for the terrorist, but rather had her own objectives with that whole mess, the terrorist also being her enemy.
