If you want to talk about the darkhorses of the Spring season, The World Is Still Beautiful might make up for a good possible candidate.
While you might just call this Disney: The anime, Soredemo Sekai Wa Utsukushii is a charming shoujo-shoujo-sparkle-sparkle-doki-doki set in a fantasy setting with alot of castles, forests, positivism and forced marriage with 12 year olds. Oh wait.
All jokes aside, it is charming. And very shoujo. The MC has spunk and it’s rare to find these kinds of romances in anime: So yeah, Soredemo, it’s good, try it out. Maybe it’s not especially memorable or groundbreaking, but it’s a good fix for the fantasy romance lovers, I guess.
