Best Student Council(2005)

Gokujou Seitokai

Randou Rino is a young girl with a head full of air and a talking puppet on her hand. She is accepted into the illustrious Gokujou all-girl's school, and is summarily, almost curiously, accepted as part of the even more illustrious Gokujou Student Council, who has more power and business ventures than most large businesses. Now a part of the student council, she befriends the talented members of the Gokujou Student Council, leaving one to wonder how a girl with seemingly no talents or redeeming qualities would get chosen for such a group.
