When it comes to feminist-friendly narratives in JRPGs, honestly my first thought is Trails in the Sky. It is originally from Japan, true, but something like 90% of it was translated and localized by a woman, which I think gives it an advantage when it comes to positive portrayals of women in games as written *by women*. It may not succeed at all times, but overall I think its diverse representation and fleshed out female characters go a long way towards creating a solid foundation for a feminist narrative.
Starting with its female protagonist seems like a good introduction. For one, it seems like the game was originally conceived with a male protagonist with a secondary female lead. The developers apparently decided they wanted to go with a female protagonist instead and simply swapped their genders (so at least part of the progressive stuff in the game is in the original, even if the female-led localization probably accounts for more of the subtle ways it feels feminist to me). It's amusing how far this goes towards contextualizing Joshua's role in the story to me. Originally, apparently the dynamic was going to be the slightly naive rural boy as the son of the Legendary Hero while the secondary lead female was the Mysterious Waif with the equally Mysterious Dark Backstory. I think the reverse in roles helps round both Estelle and Joshua out by defying some common tropes. One example that comes to mind is how Joshua, despite being this badass assassin, always kinda feels like he's the damsel in distress, even though I don't think he ever gets captured (his distress is mostly self-imposed). Whereas Estelle, despite actually being captured (by a 14-year-old girl who ends up being the best antagonist) never feels like she's lost control or agency. When she's alone and unarmed behind enemy lines is when she narratively makes the biggest crack in the villains' armor.
While the shadow of Cassius looms over a lot of the first game, the narrative *does* introduce a large number of female foils for Estelle to play off of. She has her anime rival Anelace, who is both initially more skilled than her as a slightly-older Bracer AND trained in the same sword style as Cassius to give it some personal weight. She has her romantic rival and hot-cold opposite Josette, who starts as a comedic character but grows by the second game so that their dynamic is more of a true personal ideology juxtaposition. There's also Schera, who acts as all of mentor, mother, confidant, and sometimes-dependant throughout the course of three games as Estelle matures. If you're ever curious where in her development Estelle is, you can look at her relationship with Schera. You can also add Chloe and Queen Alicia here to a point, but they are less foils and more 'best friend/sounding board' and 'ideal to strive for who isn't Cassius'.
I like Estelle a lot. I like how she has a fairly wide range of interests from Bracer training to bugs to Joshua to acting to sneakers. I like how they managed to give her a romantic subplot that didn't feel like it was trying to be the WHOLE plot. I like her snarky, playful dialog. And I like that she's regularly depicted as using her empathy, interpersonal skills, and ability to read people as her strongest weapon, even as she steadily overtakes all of her allies in sheer physical strength/determination. Counterpoint: I do worry that she can be read as 'a Mary Sue', but I feel the struggles and challenges she faces end in failure often enough that she certainly wouldn't read as 'too perfect'. Perhaps her somewhat flighty personality early on can come off as following the 'Manic Pixie Dream Girl' trope, too. Worth addressing, but for me she always sounded like a real person, with a mix of humor, seriousness, faults, talents, and interests.
The wide range of female characters in the Sky series goes a long way to making this game feel very feminist to me. You have a wide range of ages, professions, intelligence, strength, competence, interest in romance, and even *some* diversity in body types! (No one is fat, but you have short, tall, busty, slim, and muscular, which is pretty diverse for anime female standards, at least!) It's worth noting that the male cast has a pretty diverse set of characters, too, so a lot of the flaws in the female cast can tend to be found somewhere in the male cast as well, balancing out how poor the representation can be in my eyes.
The country is led by a Queen, reminding me of Suikoden V a bit (the OTHER really good for represenation game that comes to mind immediately). Alicia doesn't get much screentime until game 3, though, coming off as mostly just super-competent but in an impossible position for most of the first two games. Chloe herself becomes the heir-apparent to the throne after a nice parable about keeping incompetent men out of power when Estelle verbally owns Chloe's uncle Dunan, the previous next-in-line. Captain Julia is notable for being the most skilled (non-Cassius) soldier in the army. She even gets a short arc in the later games about how this has brought a lot of fame on her that she really didn't want and has to struggle with balancing a professional public appearance with her disdain for being fetishized in the public eye due to her gender.
Calvard, the Far East-inspired neighboring country also has a female Ambassador. And Kilika, characterized as the strongest (non-Cassius, again) member of the Bracer Guild also hails from there, and just has a great presence during the arc where she's around. I love her disinterest in the shounen love triangle rivalry that Zin and Walter have going on around her.
On the other end of the spectrum, characters like Tita and Dorothy have a more vulnerable and sensitive personality, but both of them manage to have surprising skills and drive that keep them from simply being victims. Dorothy in particular gets to be a comic relief character forever while still having meaningful character arcs in the later games, which I found to be an interesting balance. I'm curious if she has a more important role in the larger meta-narrative as more Trails games come out.
Tita's mom shows up in game 3 and is clearly the one in charge in every situation she's in. She's a loud personality with a lot of talent... perhaps to a fault? Worth pointing out that she's introduced as a duo with her husband who is also a scientist, but she's clearly the more skilled and noteworthy of the pair.
The female villain cast is less stellar. For all that I think Luciola's backstory works, she's just not very interesting in the present. Captain Amalthea works pretty well as a foil for Julia later, but she makes a pretty terrible first impression as a love-struck hanger-on villainess.
Where I think the female villain cast DOES work is with Renne. They set her up as a foil for all of Estelle, Tita, AND Joshua, and the multiple cast relationship dynamics helps to sell her as a threat AND as a person. Her backstory is SPOILERS so don't read this: She suffered some awful trauma in the past, similar to how Joshua did, and somewhat remniscent of Estelle losing her mother. And directly in contrast to Tita's relatively-trauma-free life. However, I have to say that Renne's being sold into child prostitution and having to disassociate herself into ~5 personalities that she slowly fantasized as dying off in order to protect her is WAAAAAAY worse than anything anyone else in the series goes through. It is no wonder that it takes 5 games of Estelle's concentrated efforts before Renne can finally emote like a relatively healthy human. (It tooks Joshua like 7 years. Estelle's getting better at this!) While I'm wary of any narrative using 'rape as a backstory', I think Trails gives it the time and seriousness to actually respect the topic, and isn't gratuitous or flippant about it.
I'll toss a note in here about Olivier too, since it's really rare for any game to feature a bisexual playable character at all, and Olivier manages to be funny without ever being a complete joke. He does a nice job subverting the 'dandy playboy' trope or whatever it's called, due to using the overt flirtations as obfuscation much of the time. But he also seems to genuinely love his companions, male and female. I feel like more could be done with him in this sense, but I haven't played the Trails games where he shows up outside of the Sky subseries.
And outside of the Sky subseries, I don't know how progressive the series is. The Zero/Azure duology focuses around teenage police officers, one of which appears to be a magical construct shaped like a little girl (...why?). And the Cold Steel games are apparently set in fantasy High School, with some harem-y aspects. Not a great look, but it's possible there's more going on beneath the surface there (I hope!). After all, Trails in the Sky manages to have a lot of great feminist qualities despite Cassius Bright existing!
