What's it called when anime and manga chooses not to show nipples but make it as erotic as possible? I recall in No Game No Life, they did this in their match-up against Jabril the Mugol.
Here's what I think:
I believe that would depend on the extent of eroticism being shown, although I think the word you're looking for is simply 'censored'. If they are
Anime that contain a lot of sexual humor but no outright pornography
then they can be classified as an Ecchi anime that is censored. No Game, No Life is one of them.
This might be confusing as some ecchi anime like Araiya-san!: Ore to Aitsu ga Onnayu de!? are still classified as ecchi yet one who does not know its classification might say that it is hentai. If you watch it, you'll see what I mean. In which case, I think it would be less confusing to use borderline hentai for ecchi anime which is almost but not classified as hentai. 'Borderline hentai' anime which censors nipples include Kiss x Sis.
Both terms, ecchi and borderline hentai, may or may not censor nipples depending on the anime. As far as I know, there is no specific term for an ecchi or borderline hentai anime that is censored.
