No clue. The reviews I've seen don't indicate the language being unusual. The English is just 'eww'. The art is typical Yoshinagi, but the story may be intriguing ... On the other hand, vol. 2 devolved at the end to being a het romance rather than a social study. Disappointing, I vaguely hope it goes back to being a society study.

I'll mail these to you in a week or two and you can see what you think.
