If you're looking for anime similar to Shoujo Kageki Revue Starlight, you might like these titles.
When Utena Tenjou was very little her parents died, and a prince comforted her in her time of loss, giving her a ring with a rose seal. He so impressed her that she decided to become a prince herself one day. Now, Utena is a teenager at Ohtori Academy who's athletic and notorious for dressing in a boy's uniform. When a member of the Student Council humiliates a friend of hers Utena challenges him to a duel, and he accepts only when he sees she possesses a rose seal ring. She soon discovers that this is no normal duel - it's a bizarre and ritualistic battle that the Student Council regularly conducts. In fact when she wins, Utena finds to her considerable chagrin that she gets to have Anthy Himemiya, a rather docile student, as her 'Rose Bride'. If she wants to keep Anthy she'll have to win more duels against members of the Student Council and others. What is the ultimate purpose of these duels and Anthy's role as the Rose Bride?
Both series feature a lot of performative elements, like songs, stage play elements, and dueling. Utena is far more transgressive, even to this day, but Starlight definitely has taken notes. If you want a show about odd school life with fantastic elements such as odd architecture, larger than life duels, and other forms of intrigue. Look no further.
Fans of either would do well to check out the other.
