Warau hanoko-sama and Koi dano Ai dano
The prequel is nice too. I recommend you start with that, Warau kanoko-sama. This story is my favorite, for the protago is smart and emotionally strong. She is funny too! The best! She doesn't let things get to her, you know?
Soredemo Sekai ha Utsukushii
Don't like it very much because everyone falls in love with her.
Tomo-chan wa onna no ko
She is dumb and strong. Rather nice 1 page each chapter kind of story. Her best friend is all in one. Strong, smart, cold, beautiful.
Gokusen
She is really dense and strong. Second favorite!
Mikado no Shihou
She is strong
This time I will definitely be happy!
She is strong and smart.
Hirunaka No Ryuusei
Both strong and smart too
Drop!!　～A Tale of the Fragrance Princess～
She is both strong and smart. Though I haven't read the manga as of yet
Well, these are the ones I remember!

Warau kanoko-sama*

Personally I like
-Emperor and the female knight
-beware of the villainess!
-This girl is a little wild
-Crimson Karma ,and
-The Reason Why Raeliana Ended up at the Duke's Mansion (=・ω・=)
