Utena and Anthy have become close during their time as roommates. So, when Anthy casually mentions she has a brother, Utena can't help but feel shocked. She thought she knew Anthy, but the longer she and Anthy are friends, the more she discovers she doesn't know. What other secrets could Anthy be keeping? However, Utena won't have time to dwell upon such matters. A new group of duelists has emerged from the shadows. These new challengers wear black rose signets and seek revolution, but their methods are different than those of Ohtori's Student Council. They do not wish to possess Rose Bride; they want to kill her.
