@Cennekie (and anyone else interested in some good strong FML stories, here's my list of recommendations)
Rather than brave, most of these ones have strong, well-rounded FMLs overall that I recommend. You won't be disappointed. I hope at least one of them is new to you and enjoyable
~ is next to my personal favourites. Gotta show some bias hehehe
Long strip stories (the bulk of vilenesses):
~
To be You for Just a Day / Your Throne (webtoon title) : has two central FMLs, one starts strong the other develops well over time. Keeps you on your toes, wont disappoint.
It Looks like I've Fallen into the World of a Reverse Harem Game : FML is cautious and resourceful, brave in her own right.
Cheating Men Must Die : This is a lot more lighthearted and comedic compared to the others but FML kicks ass literally every chapter. Author is great with originality each arc.
[
Scream Queen : has a similar vibe to 'Cheating men must die', haven't read a lot of it but the FML is brave and head-strong. Adding it because I just remembered it lol] *edit
~
Reminiscence Adonis : Pretty deep into the story rn, and not really a villainess story like the others but FML is uber strong, brave, and stunning.
~
Death is the Only end for a Villainess : Someone already mentioned this as of now but I wanna promote their recommendation lol, FML won't let you down
The Villainess Reverses the Hourglass : From start to finish the FML is out for revenge. Well, a slice of romance too, but we're also here for the revenge!
Tamed a Tyrant and ran away : The long strip for this just started but the FML is strong and determined, high expectations for her and the story.
~
The way to Protect the Female Lead's Older Brother : Also just started, kinda bloody but not noticeable because FML is a catch and plot is amazing, I was hooked fast.
The Golden Haired Wizard : Brave somewhat from stupidity lol, more comical but story can get really serious, the plot has picked up these recent chapters so I'd recommend it rn.
*these ones I haven't read in a while or don't want to emphasize but had strong/brave FMLs while I was reading them: Ebony, Remarried Empress. Other's Romance, The Villainess Lives Twice
Ones that are not Long strips:
~
Raise wa Tanin ga Ii manga : FML is a yakuza daughter and she takes BS from absolutely no one, updates aren't very frequent but personally worth the wait for me. Highly Rec.
The 31st Concubine : FML is brave, strong-willed, and clever. Unlike others FMLs in this situation, she doesn't waver over stupid things nor is she unnecessarily indecisive.
Koi desu ga Koi Janai : Very different from the other stories, hasn't updated in a long long time and idk if it will so read at your own risk. FML is unconventionally brave, I appreciated it, so it's on the list.
*Not as many on this list besides what you've mentioned so I hope you don't mind all the long strips. These are all the stories I know of with brave/strong FMLs. Hope ya'll find something new to enjoy!
