ohhh from this new season you need to check out Overlord, it's amazingly fun and cool 8D and it's a trapped-in-a-videogame anime that is both really good and really original! I don't wanna spoil anything, just give it one episode to reel you in XD bonus: there are monsters!
Gate: Jieitai Kanochi nite, Kaku Tatakaeri is also good, it's about a gate opening in Japan that leads to another world that is like medieval and there's magic and creatures, it's really good, also give it an episode if you want to, bonus point: there's an elf!
there are others in my profile, but they aren't as good as those o:
HOW COME YOU DON'T KNOW OF THE BEST ONGOING MONSTER GIRL MANGA THAT JUST NOW GOT IT'S OWN ANIME THAT'S ON EPISODE 4, GO CHECK IT OUT DARLING <3
main cast is a lamia, a harpy, a centar, a slime girl, a mermaid, an arachne, and a dullahan (it's a harem show) it's also ecchi and absolutely ridiculous, the arachne is into bondage, the mermaid is into tragic love stories, the centaur wants to act as a hero, the harpy is a total airhead (and adorable) go check it out XD
