One Piece weird obsession with 16 y.o girls

Someone already posted smth similar but if it happened once or twice it would have been a coincidence, but it’s so weird how often he makes these 16 year old characters an sexually appealing or in dubious situations when they could have easily been a little older and nothing would have been lost.

Pudding is a 16 year old in an arrangement wedding with Sanji, a 21 year old guy. Some would argue that her mother eats people so making her young daughter marry an older guy isn’t a big deal. But then we have Rebecca’s mother who married a 25 y.o man as a 16 y.o too.

Then we have Vivi who’s main attack is to perform a dance and release a perfume, she’s also a 16 y.o

Also Rebecca, who’s supposed to be a warrior but dresses in the most sexually appealing way possible, even though she’s a warrior and let’s not even get into how she also ends up being saved by men.

Finally we get Shirahoshi. She’s supposed to be even more beautiful than Hancock even though she’s not even fully developed yet and get into hentai situations like the one in the picture.

Yes, teenagers can dress in skimpy outfits, behave in a sexually charged way, etc, but when you put everything together it just makes me uncomfortable, specially because going by their personalities I wouldn’t put Rebecca, for example, dressing the way she does. It’s also so suspicious that all of them are exactly 16 years old, why not 18, 20?! It wouldn’t have made a damn difference.

Take Rebecca’s mother for instance. Why the hell did she have to marry at only 16 y.o to a 25 y.o guy? It’s a flashback! But there has to be this age gap for some reason instead of them both NOT being teenagers.

I’m honestly surprised that Nami was 18 at the start, Robin 28 and Hancock 29.
