@MangaField:
Also, the characters you mentioned are never
Didn't I mention Rumiko? You should take a look at Urusei Yatsura and Maison Ikkoku. Then there's Dragon Ball and nudity jokes there. Basically that's the point where cultural differences start to matter. For example, try to imagine Pom Poko being made by Disney.

@elefantine97:
basically, i can't rationalize my way out of thinking they're not kid characters and thus, i can't enjoy it
That's understandable, but the best would be to look for another material instead. Basically, I'm not seeing kids here. I'm seeing toons. For them to look like kids, I'd need different graphic style, like in Vagabond, or that loan shark manga. Then it wouldn't fly.
Me, I'm just happy the author dropped that ridiculously overstretched "another world in the book" nonsense and now it starts resembling the standard "Harem Comedy with Ridiculously Crude Over the Top Jokes". Those were a great source of slapstick comedy and it's been ages since there was something decent in that area with all the reincarnation isekai craze. I mean, Girl's Bravo, Aika Zero, To Love Ru. Well, already mentioned Urusei Yatsura was close, but not quite the same thing. The closest I remember to that was Ben Tou, and Jitsu Wa Watashi wa, which had the same spirit, despite being less perverted. And those were released years ago.
