Revolutionary Girl Utena

Utena Tenjou is a schoolgirl in the eighth grade of Ohtori Academy. She has the strange memory that, when she was very young, she met a mysterious "prince" and was given a ring with a rose signet. One day, Utena finds guys are making fun of a love letter somebody posted, and she finds it was written by her best friend, Wakaba, for the captain of Kendo Club, Saionji. For the sake of her best friend, Utena challenges Saionji to a duel. Then, Saionji tells her to come to the forest of the Duel Arena.

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.

Utena unintentionally unleashed the Power of Dios in the last Duel with Saionji, which attracted Touga's interest in her. Touga sends Utena a dress for the upcoming ball. On the other hand, Touga's sister, Nanami, thinks her brother likes Anthy, and in a fit of jealousy, she sends Anthy a water-dissolvable dress.

Utena and Miki are about to begin a duel. The rest of the episode and the following one are flashback to show what has caused this duel. Miki often plays a particular tune on the piano. He says he cannot truely play the tune as he wishes because he has lost a "glow". Nanami thinks that Miki likes Anthy, and from jealousy, she tries to tease and razz her. Taking advantage of that, Miki makes a good friend of Anthy, and then Utena. Finding Anthy and Utena got poor grades in the previous math exam, Miki offers to tutor them. However, Nanami won't leave them alone.

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

Lately, someone has been trying to take Nanami's life. Overhearing a conversation between Anthy and her brother Touga, Nanami misunderstands that Touga is the one who is trying to kill her. After that, someone saves Nanami out of a danger and she falls in love with him, who turns out to be a young boy. Nanami asks him to be her boyfriend, but she does not seem to know the difference between a lover and a henchman.
