Prepare for a long one.
The thing is... Most gender swap stories just "transform a guy into a pretty lady" and mostly use it in the comedy genre. Just like "Magical Trans", "Onii-chan is done for", etc... Not saying that it is good or bad. Just saying it's repetitive.
The only story that I saw where it was used as the core of a serious story was "Transjister". Go read it but it possesses self harm and other grim stuff.
And I don't enjoy it much. Bad memories.
Here in "Yakuza Reincarnation", however, the Gender swap really does a wonderful job because it is used in a different way than normal :
Not in a "I'm a virgin/overly conscious dude that never saw a naked female body in muh life..
It was used to accentuate the gap between the supposedly young and frail body of a pure and innocent princess that rarely saw the outside world and the merciless acts of an old strategist, expert in fighting both with Hand-to-hand, sword-skill (and probably more) Yakuza. It makes the actions stand out even more and make him seems even MORE Badass.
You could say that a shota could have also worked... But not on the same degree as the princess body.
Actually, it's way better with the princess because it breaks so many tropes of both the Isekai and Gender Swap genres.
Because actually, most of the people writing a story wish to stand out when compared to the same kinds of story.
I mean, HOW MANY generic Isekais have you seen? With the same "MC OP AF" twist? With the same story arcs? With the same Harem? I've seen plenty myself.
Point is, I don't just blindly like the Gender Swap in this manga without a proper reason. I actually love how it was used and how it made the story a bit more unique compared to most of the Isekais out there.
It blends in very well when you think about how the other ingredients were pretty scary at first.
You can't just mix in some popular tags and just consider it "Ez Money" without putting in some efforts. And here, the author put the god damn effort to make it all work pretty well.
Also, tf...?
