I do remember that she is more confident as the series progresses, and bolder when it comes to going after Issei but she is more confident in her battle abilities as it progresses because she was timid and shy, and she still retains these traits but she is more confident that she was before maybe associating with Rias and Akeno helped her out quite a bit.

I do like her character quite a bit because of her naivette and innocence compared to the others it adds a touch of class to her character, and makes Issei's Harem much better.
