I know we weren't bringing up anime, but what does everyone think of Houseki no Kuni/Land of the Lustrous? The gems are all genderless and sexless, and it's basically as elegant and striking as something like Revolutionary Girl Utena (including the characters, my goodness), and I think the text practically begs for a feminist reading. That said, there is arguably light 'fanservice', and the gems are arguably coded female, at least in the anime, in virtue of having female VOs. But really my ulterior motive for bringing it up is to possibly convince some people that it might be an exception, because as a whole I think it's brilliant and I can't stop thinking about it. I just also thought that it has a pretty distinctive feminine sensibility that may be of interest. Though probably more so in the case of the manga overall.
But it's pretty sad, so be forewarned. But to speak to its potency, Cinnabar's story emotionally wrecked me in the first episode.
