I would say quite a few, but they don't really seem that way. Shuumatsu Nani Shitemasuka? Isogashii Desuka? Sukutte Moratte Ii Desuka? - might look like another lightweight fantasy harem story but actually has one of the best romantic pairs recently and handles some pretty hard topics. Actually I would say a Shield Hero is another one. It might look like yet another cookie cutter isekai show, even with some of the heroes being summoned taking it like if it was just a game. But it turns out it's a real and rather brutal feudal world where your actions have real consequences and a lot of people have very insidious evil and inhuman agenda. Hell, I would actually even call Kemono Friends (series 1) an adult series. What looks like a funny child series with anthropomorphic animals turns out into something much deeper once all the various hints and fragments of information start to fall in place.
