Organisation: Ootori Gakuen Seitokai

Ootori Gakuen Seitokai (Ohtori Academy's Student Council) play a vital role in the series. Moved by his or her own personal interests, their great objective is to bring "World Revolution" and in order to obtain it, a true champion must rise from their battles to obtain possession of the Rose Bride. Instructed by letters sent from an entity called "End of the World", each of them possesses a rose signet ring similar to the one Utena received from her prince, allowing them to participate in the duels. Some view Utena only as a threat to their plans, while others develop some sympathy for her. During the duels, they place on their chests a single rose that matches the colour of their hair or clothing.

"If the egg's shell does not break, the chick will die without being born. We are the chick; the egg is the world. If the world's shell does not break, we will die without being born. Break the world's shell! For the sake of revolutionising the world!" - Ootori Gakuen Seitokai oath (paraphrased from Hermann Hesse's Demian).
