Anthy Himemiya in the film Revolutionary Girl Utena: The Movie is a reimagined version of the character from the television series, serving as a more assertive and proactive counterpart. She is known as the Rose Bride, a mysterious figure at the center of a dueling game at Ohtori Academy, where the victor is granted her hand and the supposed power to revolutionize the world.

In this cinematic retelling, Anthy's appearance is notably different. She no longer wears her characteristic round glasses, and her hair is long and straight rather than braided. Her design, including a striking red and white dress, maintains her essential features such as her dark skin and the red bindi-like mark on her forehead.

Personality-wise, the movie's Anthy is a significant departure from her more passive and inscrutable television counterpart. She is depicted as being happier, more independent, and sexually assertive, particularly in her interactions with Utena Tenjou. While she retains an air of mystery, her motivations are clearer; she is actively seeking an escape from the closed world of the academy and the oppressive influence of her brother, Akio Ohtori. She is no longer a purely submissive prize but an active agent in her own liberation.

Anthy's background is intertwined with the film's symbolic and tragic history. She is the sister of Akio Ohtori, who was once seen as a prince named Dios but is revealed to be a corrupted figure, described as the Lord of the Flies. After a traumatic event in which Akio rapes and stabs Anthy, he dies by falling from the academy. This history cements Anthy's role as a "witch" in the eyes of the world and establishes the dueling game as a means to find a new prince to replace him. Her key relationship is with Utena Tenjou, a girl who dresses in a boy's uniform and whom Anthy chooses as her champion. Unlike the other duelists who objectify her, Utena fights for Anthy out of a sense of justice and a desire to respect her autonomy, which fosters a deep, transformative bond between them. Her relationship with Akio is one of profound abuse and manipulation, from which she ultimately seeks to break free.

Anthy's role in the story's climax is active and decisive. She becomes the driving force behind the escape from Ohtori Academy. In a surreal turn of events, Utena transforms into a pink racing car, and Anthy takes the driver's seat, holding the car keys, to physically drive them both out of the academy's confines and toward the outside world. This act reverses traditional gender roles and positions Anthy as the one in control of their shared destiny. Her development throughout the film is a journey from being a prize and a victim to becoming a liberated individual who rejects the roles of princess and witch imposed upon her. The film concludes with Anthy and Utena, having escaped, sharing a naked embrace and a kiss, symbolizing their mutual revolution and their decision to face an uncertain adult world together, free from the academy's oppressive structures.

Anthy possesses several notable abilities. She is the vessel for the Sword of Dios, which her engaged champion can draw from her chest to use in duels. She also has the ability to communicate with animals and keeps a small pet creature named Chuchu always by her side. Furthermore, she can magically alter appearances, such as when she embellishes Utena's uniform, and she is capable of transforming others.
