I'm going to disagree with what seems to be the majority of the comments section and say this is legitimately good (also that some of the criticism seem off base or just plain incorrect). I'm usually not a fan of stories where a man gets reincarnated as a girl but is still basically just a man in all ways except appearance and his new female body is either just a gimmick or an excuse to make it yuri, but this has so far managed to avoid the yuri route, and, while it is still just a gimmick, it at least doesn't make things weird. It's also a series with an MC that is blatantly OP from the very start, which usually goes downhill super fast when the MC solves every problem with no difficulty, but it manages to avoid that pitfall too by giving the MC a valid and understandable reason to avoid getting involved in large scale events (several reasons in fact, though what seems to be the central reason isn't actually introduced until volume 2). The MC herself is also turning out to be a genuinely interesting character, even if it is taking her a while to evolve from simply being an old battle junkie in a little girl's body. Plus the set-up has even given us an enemy that the MC wants to defeat but is currently not strong enough to, giving the chance for some actual struggle down the line.
On top of that there is a genuinely interesting and complex struggle between the revolutionaries and people who don't think the current state of the status quo justifies the reprecussions of a war. Better yet, the revolutionaries are, despite arguably being in the right, currently being set up as the antagonists, and the only character from their ranks we've met so far is the most complex and likeable character in the series so far. The highlanders being just pure evil so far is a bit of a downer, but a simple hate-able antagonistic force isn't strictly a bad thing.
In summary, worth a read so far. It's a bit slow to get off the ground, but I actually like a slow burn like this so that's only a downside depending on taste, and it already has more complexity than your usual reincarnation LN adaptation trash.
