do you know of any comics where the "villainess" protagonist and the opposing girl team up? like your throne
Oh, I love Your Throne! S1 of Your Throne was my favorite for this exact reason.
I can definitely think of other comics that do this sort of thing, though not quite to the extent Your Throne does or in the way Your Throne does. I'll list a few I can think of which you might enjoy and you can let me know if any of these work!
Beware the Villainess (by Soda Ice and Blue Canna) is an isekai in which the story's protagonist is the villainess and she befriends the OGFL. I actually stopped in the middle of reading this one to check if it was GL, so of all my recommendations, this is probably the closest.
Not Your Typical Reincarnation Story (by A-Jin, DOYOSAY, and Lemon Frog) does this to an extent? I can't elaborate without spoilers, but I think you'll at least find this one interesting if your focus is on the relationship between the main female characters, as their dynamic was among my favorites.
Nevermore (by Kate Flynn and Kit Trace) has the female protagonist team up with the female antagonist, though it isn't really an isekai (but it is GL). The art on this comic is gorgeous, too, which makes it very much worth the read, and all the characters and relationships have been very interesting. It isn't exactly what you're asking for, but if you enjoy horror, I think you'll like it.
From a Knight to a Lady (by Ink. and Hyerim Sung) also sort of does this, though the protagonist isn't a villainess. Neither women are antagonists, though the other woman starts out antagonistic toward the FL. That said, I'm including it because I really enjoy their friendship and their friendship has huge relevance in the plot, which isn't always something you can say for female friendships in this genre. It's one of my favorite parts of this story, so it's on the list.
The Makeup Remover and Surviving Romance (both by Tee Yeon) both sort of fit, but not exactly. TMR has the protagonist coming to understand the antagonist, and SR is an isekai which strongly focuses on a number of female friendships. Neither are exactly what you're looking for, but they're both well-written and have a lot of female friendship dynamics as central parts of their storylines, so I think you'll be satisfied with either.
Not an isekai at all, but My Sweet Archenemy (by RosieDuong) is about a superhero and a supervillain who are friends as civilians, so this would probably scratch a similar itch. It's more a comedy than Your Throne, so keep that in mind if similar tone is important. That said, the art style is super charming and the cast is very fun.
The Dark Lord's Confession (by Topseoung) is about a woman trying to kill the Dark Lord who ends up accidentally summoning said Dark Lord, which ends up forcing them to work together to lift a curse the Dark Lord created. The art in this one is absolutely gorgeous and it's a favorite of mine, plus the main character has a few other female friendships which also drive the plot. It's a neat read, so I think you'll definitely find something fun here.
I'll round this off with I Became a Level 999 Demon Queen (by LEE JAE-I and Hangaga), which is a comic I started recently. It follows a villainess character who has befriended the OGFL, though they haven't yet interacted more than once. It's too soon to say whether they're going to team up or face off against each other, but it may be worth keeping an eye on.
Thank you so much for the ask! Let me know if you end up liking any of these.
