Anthy Himemiya is the dueteragonist of the anime series Revolutionary Girl Utena.
Anthy appears to be a quiet girl, but she happens to be the "Rose Bride" who, by rules set down by the mysterious entity known only as "End of the World", must serve whoever wins the Rose Crest Duels. When the series begins, Anthy was serving abusive duelist Kyoichi Saionji. After Utena Tenjou defeated him, Anthy left Saionji for Utena. As the Rose Bride, Anthy provides the Sword of Dios for her "engaged" duelist. Apart from Utena, Anthy's only companion is a small mouse-like creature called Chu-Chu.
Anthy is unfailingly polite, pleasant, and faithful to Utena and everyone as a student and the Rose Bride. However, as the series goes on, it becomes clear she has a dark side that she typically shows through passive-aggressiveness. Thanks to Utena' determination to save her, Anthy finally frees herself from Akio's endless quest for power via the dueling game and leaves him forever.
