The setting is kind of an interesting yet bizarre mix between the mobile game "Girls Frontline", with the idea of cute anime girl androids used as military troops/commanders, the Imperial Japan Steampunk-mecha setting of the "Sakura Wars", and the slice of life moe of working at a cafe from "Is the order a rabbit?"/Gochuumon wa Usagi desu ka?. As such, it is partly a very classic cute girls doing cute things show, but also in the backdrop of a postwar setting, where all the main girls/robot "dolls" are basically retired from combat ala Girls Frontline, and there's still political powers at play, alongside a suspicion over the dangerous nature of the "dolls". It's not the MOST intriguing plot ever, but it's got really nice looking animation and budget (better looking than devil is a part timer s2 at least), plenty of moe comfy-cuteness, and just enough occasional action and mystery to pique your interest.
Of course, I do not recommend this show to everyone. If you ARE a big fan of those slice of life, CGDCT shows, and are perhaps ok with some occasional action and drama with this unique setting, then yeah, this is something you should check out.
