Joou no Houkago ~The Legend of Reina~

Reina Ryuzaki (first-year high school girl): Her weapons are her girlish looks, short stack stature (with a surprisingly generous bosom), and her cute smile. Her goal is to become a charismatic leader and a celebrity at the top of the social pyramid, cute as a hare but hungry like the wolf!
