Shoujo Kakumei Utena, Romeo x Juliet Recommendations
Juliet Capulet, the heroine of Romeo x Juliet, is the Utena Tenjou of a new generation. She's tomboyish, independent, and passionate, but, like Utena, her romantic dilemma slowly comes into conflict with her tasks as a hero. If you're tired of seeing moe schoolgirls and crabby tsunderes as female leads and want more heroines like Utena, give Romeo x Juliet a try. You might just end up rooting for the House of Capulet.
Both series are based on the idea of Revolution- Both also have a very romantic European feel to them and have lots of roses and flower petals and the like. Both deal with tragedy and sacrifice for the sake of love and revolution.
Both feature a lot of sword fighting and as the previous person mentioned, Juliet is kinda like the new-age Utena, except unlike Utena, Juliet doesn't mind being girly.
Both series have a very similar feel and kinda have their own bizzare little world, and both are, of course, romantic, beautiful, and just plain fun.
At first glance, the audience will notice some similarities, both stories have pink haired, tomboyish protagonists that duel using swords. There's heroic self sacrifice in the story somewhere. You can also expect a "Prince" and a "castle".
Also, these two are similar in that they have great OSTs/ music in it. The songs in each of these anime are catchy and doesn't get old (How can you go wrong with You Raise Me Up and Rinbu Revolution as your theme song).
Fun fact: RxJ premiered exactly one decade after SKU, give or take a few days.
