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.
