>>37879256It's only a fairly recent thing where they've decided that panty shots are taboo and not allowed in most kid's shows. Even some adult cartoons seem to have a 'panty shot budget' where they can only have so many before they hit the limit. It's one of the reasons why I was so shocked to see this. Not because there's anything wrong with it but because you simply don't see it anymore in most modern anime.
I thought it was to do with some governer Ishihara being anti-'smut' and changing regulations to get rid of 'tantalising' stuff he didn't like, but I'm not sure if that's actually the case.
