Based on consultation with a tagging guidelines doc, I've removed the historical/slice of life/(high) fantasy/incest tags. Also, slightly more controversially, the sexual violence tag,. If anyone knows why it's tagged that let me know and I'll re-add it but the current incidents seem just violent eating people and not like whatever was going on in beastars.
I'm replying a year later, but with what's happened up to chapter 26, I'd say you can put the incest and sexual violence tags back on.
If the tags don't get put back, then maybe this comment will serve as a warning of sorts for people that checks for it before reading.
It's not horrible or unbearable to go through (your mileage may vary), but it's not a pleasant part of the read, it mixes animal logic on how it's common for animals that are in the same family to breed, and the human pressure and blackmail (of sorts), so it's hard to judge on a morality scale or to be detached since the characters are humanized and display human feelings and emotions.
