Basara - Girl takes over her brother's role and becomes a revolutionary leader. She goes on a quest to find allies, which of course leads to lots of fighting, and even falls in love... with her mortal enemy without realizing it.
Saver - Non-idealistic, mostly stoic. Physically strong sword-wielding heroine. Does not go out of her way to save everyone if it means a risk to herself. Refuses to become anyone's possession, even the male love interest! Flaws of this manhwa would be the lack of romance and the confusing/weak plot.
Talking About... (Josei) - There are three main female protagonists. They're all very different from each other, but are friends. My favorite is Amber. She's basically a successful careerwoman and a player. Has no urge to marry and settle down. She uses men for one-night stands and moves on.
Hiiro no Isu - Female fighter searches for childhood friend. I don't remember much about this manga, but I do remember the heroine being "refreshing."
Gu Fang Bu Zi Shang - Heroine is some sort of assassin/mercenary, but she's a very learnéd woman. She charms the main guy with her eloquence and music.
Kuragehime (Josei) - Lead is a nerdy NEET (no pursuing education, employment or training) with an obsession for jellyfish.
Cheese in the Trap (Josei) - She's a very perceptive person, which causes her to over-analyze at times. Of course, because of this, she sees through a popular upperclassman's good guy persona. Other than that, she's a very normal slice-of-life heroine actually. Painfully slow romance, but the characters in this are generally mature and rational. Viva college students!
Shoujo-y plotlines (not necessarily a bad thing):
3D Kanojo - It's actually a male lead, but the main girl in this is pretty different. She's basically a pretty girl who's popular with boys and hated by other girls. She doesn't care what people think of her.
Warau Kanoko-sama and the sequel
Koi Dano Ai Dano - Average looking, but extremely observant and rather cynical. Schemes a lot. Not used to having friends, and dense when it comes to love though (much to the main guy's frustration, lol).
The Kidnapping of Minja Jo's Boyfriend - Female lead is a delinquent. In other mangas, she would normally be the villain or other woman. Basic premise, she kidnaps the boyfriend of her long time rival to make her rival submit.
