Revolutionary Girl; Utena!

Revolutionary Girl Utena is a manga and an anime. The main character is Utena Tenjou, a tomboyish teenage girl who decided to become a prince instead of a princess when she was young (expressed in her manner of dress and personality). She attends Ohtori Academy, where she meets a student named Anthy Himemiya, a girl who is in an abusive relationship with another student. Utena fights to protect Anthy and is pulled into a series of sword duels with the members of the Student Council. Anthy is referred to as the "Rose Bride" and is given to the winner of each duel. As Anthy is thought to be the key to a coming revolution, the current champion is constantly challenged for the right to possess the Rose Bride.

With its plays on such archetypal figures as the Prince, the Princess, or the Witch, and by the literary symbolic role carried out by such plot elements as coffins, thorns, or castles, Utena can be seen as the quintessence of the Postmodernist fairy tale. One important aspect of Revolutionary Girl Utena is that it grabs traditional ideas and perceptions, and twists them around. For example, it is often debated-and indirectly shown, in the series that Anthy and Utena are both the princesses of the prince who is Dios, or Akio, or both. This is in stark contrast to the generally accepted trope that princes have only one princess, whom they unfailingly love and protect. Dios and Akio are both shown to be protective of Utena and Anthy in their own way but are incapable of doing it properly. Dios' self-destructive altruism leads to Anthy position as the Rose Bride, his existence as a powerless spirit, and the creation of Akio. As for Akio himself, it is debated how much he really cares for Utena or Anthy, but his ambition and lust for power ultimately overrides any love he might have felt for them both.

It should be noted that the series invokes sexual themes quite often (especially in the final arc), some of which are incestuous desire, actual incest, and sexual abuse. While these themes are often important within the narrative, they are usually not directly stated or shown in the series. There is somewhat more explicit sexual imagery in the motion picture, although it is still far from pornographic. The omnipresence of phallic symbols, such as swords, towers, and cars, and the sexual connotation of dewy petaled flowers contributes to the sense of urgent sexuality, repressed and otherwise, in the series.

Another very important and recurrent theme is of gender roles (freely chosen or socially imposed), which play a large part in the series, from its very premise in which Utena wishes to be a prince and not a princess. As problematised as gender is in Utena, sexual desire itself is quite fluid; most characters at least hint at having both same-sex and opposite-sex attractions.
Chief among the romantic relationships in Utena is that between Utena and Anthy. It is subtle in the TV series, but less ambiguous in the movie. While Utena (especially in the movie) is boyish, strong, and physically aggressive ("masculine" traits), she is more emotional and innocent than the wearily experienced Anthy.

Much of the series -- arguably, in a way the entire series -- revolves around the transition between childhood and adulthood, and all that implies, notably development of sexual feelings and identity and the loss of "innocence." Most of the characters are estranged from a loved one in their childhood, something which affects them deeply and arguably stunts them, and this relationship is often complicated or corrupted by a sexual element.

Another theme of Utena is the reinterpretation of classic shōjo manga themes and motifs. Examples may be seen in the failure of "heroic" male characters, Utena's refusal to become a princess (and refusal to sacrifice her femininity in order to become a 'prince'), Anthy's subversion of the demure female role, and various plays on conventions in the genre, such as the transformation of outfits and idealized notions of friendship and love.

I love this series, LOVE IT. It embodys so many amazing ideas and actually gives justification to the girl who was always the prince in the pretend games with friends (guilty). Utena (in all her incarnations no matter what) is (one of) my HEROINE(s).
