Good shoujo mangas with strong heroine?

i dont like mangas where the heroine is a crybaby. i prefer mangas with strong heroines, especially if that main character can kick butts. :) some mangas i love are ouran high school host club, hot blooded woman, basara, saver, tokyo crazy paradise, vampire knight, skip beat, etc... if you have something in tht strong heroine genre then please recommend it. thank you.
