Wait, which one is which? The only one I recognize is Mio and hers wasn't really played either way.
I'm a bit late for this, but...
From what I remember, the episode where Mio came out as a nudist had her basically apologizing to the guy she had a crush on for being a nudist because she knew it was wrong and stuff like that. Said guy never really told her otherwise, just that he accepted her for who she was. Which is nice and all, but it still left the reader with a "NUDISM IS BAD!" message.
Unless I'm remembering wrong and/or there was another Mio centered episode where someone told her that Nudism was okay. I didn't finish the series and it's been a few years since.
(Also I accidentally mis-clicked and downvoted your comment. Sorry!)
