Kitaooji Satsuki

Athletic and energetic, she loves to be seen with Manaka and is the most confident in her love for him. Completely open with her feelings and not afraid to show her thoughts (or her body for that matter), Kitaouji stands out because of her alluring body. She is a G-cup (the running joke is that her breasts are so big, they weigh her down) and her blouses occasionally pop open when she is emotional. Manaka and Kitaouji have a lot in common (including their tastes in TV shows and manga and their academic records) to the point that Manaka even said that if she were a guy, she would be the boss and he would be her most loyal friend.
