tl;dr: It's ecchi trash, but it's good ecchi trash.
It really doesn't have much of a story, and the world is an anachronistic mess (they fight with bows, swords, giant hammers, etc., but they have phones and TV), but the girls are cute and likable, and lewd things happen to them fairly often. They have the kinds of body styles you would expect: loli, tall with huge boobs, and MILF, but they also have the slightly rarer oppai loli and the petite-but-not-small-enough-to-be-considered-a-loli. They're all drawn well, especially when lewd things are happening, and you get to see them in a wide variety of outfits. The girls'
interactions are enjoyable as well, and they haven't gotten catty with each other like you see in a lot of harems. Main guy isn't a hapless, audience-self-insert nobody, but also isn't some OP edgelord, so that's another plus.
It's not going to set the world on fire, but I'm looking forward to more chapters being released.
