Winning the duel with Saionji, Utena is now the Victor of the Duel and is to be "engaged" to the Rose Bride, who is Anthy. Next day, Utena and Anthy start living together in a dorm. Saionji, who is actually really in love, asks Anthy to get back on good terms with him, but Anthy refuses. Then, he challenges Utena to a rematch. Feeling the whole thing is just crazy, Utena decides to lose the Duel on purpose.

In the tune Anthy just casually played, Miki found a "glow" that he had been seeking. He has a twin sister, Kozue, who used to play a tune with a "glow". However, she does not play the piano anymore because (he thinks) of his fault. Miki wishes to protect Anthy's "glow" in her tune; however Anthy tells him that, because she is the Rose Bride, by the Rose Signet Code, she must obey the Victor of the Duel, or Utena at the moment. She even says that, if Utena told her not to play the piano anymore, she would not. Since he thinks it is his own fault that he lost Kozue's "glow" in the past, not to lose a "glow" again, Miki challenges Utena to a duel and tries to set Anthy free and protect her with his own hands

Having observed the last five duels, Touga is now positive that he has completed collecting sufficient data to defeat Utena. Touga has been implying to Utena that he is the prince she has been looking for. One day, in the rose garden, Touga shows Utena that he is her prince in concrete terms. However, he challenges Utena to a duel. Believing that Anthy wants to quit being the Rose Bride, become an ordinary girl, and make many friends, Utena decides to beat her prince for Anthy's sake.

Anthy and Utena move out of their dorm and into the right wing of the chairman's office so Anthy and Akio can be closer to each other. Then suddenly Saionji comes back to duel!

After Touga attempts to get Nanami back, she refuses and blurts out the truth. Then... that night, she sees Akio doing something very forbidden...

Utena vs. The End of the World. The truth is discovered.. about the duels, the Rose Bride, and the Prince.
