The fact that this series is set within an alternative version of Japan that instituted an all-woman wing of the armed forces way back in the early 20th century still feels kinda surreal to me. Like, I get that your average yuri series won't get anywhere near long enough in serialization to both explore the main relationship in depth and flesh out the details of the world, but it's honestly just such a fascinating setting that we'll never learn more about because this series seems to be approaching a climactic arc. It's a shame, because the premise seems ripe for a 500-chapter, alternate-history period war drama about WLW romance in the backdrop of battle, with soldiers striving to hold on to hope and maintain their relationships even in the face of wartime nihilism and despair, but there's never going to be anywhere near enough demand for it.
I'm not one of those people who argues that if something isn't popular, then it won't be good, but I honestly wish yuri as a genre was more popular, because works like this and Roid just make me wonder about all the wonderful stories we could get if yuri manga had enough demand and security in serialization to approach the depth and scope of works like Kingdom or One Piece instead of being super-niche and primarily oriented with wrapping up the main romance in, like, forty chapters at best.
Then again, even Hirohiko freaking Araki wasn't allowed to put a lesbian romance into Stone Ocean back when it was running in Shonen Jump back in 2002, so I guess mainstream Japanese magazines are just way too focused on pandering to straight male or female demographics to give queer stories the platforms they need. The most popular example of lesbian rep in a recent mainstream series I can think of was Christa and Ymir in AOT, and we all know how terribly Isayama handled that. At least we still get anime-original stuff from people like Ikuhara, so all hope isn't lost, and Urasekai Picnic, which'll be airing next season, is a legitimately great horror/mystery series that also happens to be yuri, so maybe things are taking a turn for the better.
To get back to my original point, I'm guessing this series will probably be ending in around three chapters with a love confession, shortly before Indou and Kagami prepare for deployment. The prospect of them possibly being blown to bits by artillery or dying in trenches in the various terrible wars that punctuated the 20th century kinda puts a damper on the fluffiness of the yuri, but that's military romance for you. It would've been nice to see the author exploring a relationship between soldiers on the battlefield, but I guess a full-blown war drama would be simultaneously too dark and too long for this series to segue into. I hope they at least give us, like, one panel in the last chapter showing that Indo and Kagami survived all the wars and retired safely in some cozy corner of the countryside, though.
