>>2750876There's quite a lot of older ENF that isn't so frequently mentioned:
Heart Catch Izumi-chan. Girl with inexplicable mind reading powers has a rom-com with a giant perv; he repeatedly ends up having even more inexplicable classic /e/-style shenanigans with her and/or anyone else in sight. A few chapters are (very badly) translated, available starting at
https://mangakakalot.com/chapter/heart_catch_izumichan/chapter_1or the entire raws at
https://dlraw.net/%E3%83%80%E3%82%A6%E3%83%B3%E3%83%AD%E3%83%BC%E3%83%89/%E3%83%8F%E3%83%BC%E3%83%88%E3%82%AD%E3%83%A3%E3%83%83%E3%83%81%E3%81%84%E3%81%9A%E3%81%BF%E3%81%A1%E3%82%83%E3%82%93/Paradise Gakuen. A girl is accidentally seen by a guy in the locker room and the two of them spend the rest of the series trying to protect her from being seen by anyone else. Bullying girls and inexplicably determined perverts make this a challenge.
Toumei Ningen (invisible person). A young boy discovers that eating his grandmother's salmon roe-based cooking inexplicably turns him invisible. He proceeds to make use of this just about like you'd expect, and also occasionally protects his sisters from mishaps and/or similarly-intentioned individuals without superpowers.
A few scattered instances in other works less focused on the topic:
Supeope Chuugaku (space opera middle school, but with a pun that involves writing "middle school" with the kanji for "universe"). Mostly a straight comedy, with occasional nudity, notably in volume 2 chapters 4 and 5.
Benten-sama ni wa Iwanaide (don't say that to Benten-sama). Very little ENF content, but an incident in volume 1 chapter 3 involving continuous breast expansion and the ensuing highly public clothing explosion is one of my all-time favorites.
A couple quick incidents from Buraburabanban, especially the one in the final pages (pic related).
And finally, some more modern titles that you nevertheless might not have heard of, such as Pantser Princess and Ninkoi - Karenbo Hichou.
