I didn't know about this one having only gotten into yuri recently. Flew through the whole thing tonight and enjoyed it quite a bit.
While I'm very glad more yuri is getting adapted, there isn't really all that much "woke" yuri to make into anime.
I really appreciate that Japan is being very progressive and accepting of same sex relationships. They are not hateful or scared like American animation studios. I am waiting for a possible Legend of Korra remake with a full on Korrasami pairing and a better written plot.
I'm not sure "Japan is so progressive" is exactly the right way to put it. They seem to be culturally aware of homosexuality, but in many cases not take it super seriously.
There's lots of: "oh they're just in high school, so they're in a phase, it'll pass." Also, it's not exactly easy to find yuri where the characters outright say that they are lesbians: "I mean she's a girl, but I still like her anyway." Nor are we often shown successful long term gay relationships as we've been starting to see in "western" stuff (i.e. gay moms/dads, etc (especially in cartoons like SU and She-Ra)). I also feel like in almost every yuri with a sex scene at least one girl has to protest a bit; which I think is more about Japan's view of how women should behave than an interpretation of lesbians.
Yaoi/BL is it's own version of not being all that positive. I mean the word "fujoshi" alone says a lot...
Fragtime seems lighthearted and doesn't really tip the scale in either way. I like that the narration in the end clearly stated "now that I came out as a lesbian." I don't need everything to be some dark depressing story of the painful side of being gay, I'd just like to see more work that is unapologetic about being GAY get published/adapted. Showing some positive cute gay couples goes a long way towards acceptance and normalization. I'm hoping that comics like what Kabi Nagata's been putting out will push the genre in the right direction.
