So there's no fighting and/or sex-ing, but I think from the last line you can tell it totally happens. If you want to read it, tell me and I'll write you that scene. Someday. Otherwise, well. I am lazy. :D
Finding herself in another world was not an emergency situation Haruno Sakura had been prepped for.
She improvised. First, she decided that she would deal emotionally with this situation as if this world were the product of genjutsu - genjutsu that she could not dispel, but that would have to wear off eventually, even if it felt like ten thousand lifetimes.
Then she tackled the situation as if it were real. It would at least give her something to do until the jutsu wore off. Otherwise - well. She wouldn’t think about that.
Sakura procured local dress in red, since that was nearly pink, and she was partial to the shade. It promptly got her attacked by some other faction, this one in green, whose clothing she acquired in turn.
So now she had three sets of clothing.
Weapons were the next item of business. Neither of the first two groups had had any. They fought with jutsu - fire-based for the red, earth-based for the green. She thought it was nice that they came color-coded for her convenience.
She had of course her own jutsu. Lobbing big rocks is well and good, unless you’re chucking them at someone who can bust them into teeny tiny rocks.
The fire-based jutsu had posed a bit more of a problem. She wrote it up as good practice for fighting Sasuke. And she would fight Sasuke, she thought. The words hit her in the stomach. Would. There was no way she would not be at Naruto’s side and at Sasuke’s front, looking after the boys she loved, a different way for each.
She just had to, you know. Survive a war.
Weapons. Jutsu, admittedly handy. But she couldn’t just shatter the earth every time a bandit decided that lone girl had a cute ass. It wasted chakra.
Also, it left quite the trail.
She was tailing a pair of refugees, the green sort. She’d picked them because first and foremost, she could deal with earth-jutsu the better of the two. They were an old man and a boy about her age - a combination she felt she could handle.
Also, the boy? Had a kickass pair of broadswords.
