I keep rewatching it and Karen doesn't really fit her role in the anime. She sound more grown up which isn't bad but her character is like 14(?) :\
Sonata is officially my favorite character in the show. She's so damn kawaii and she's basically the same as the weirdo energetic squirrel, Oshima Yuko <3 Chieri character now give me the impression of her being the next Yukirin because of the whole princess feel. I can't wait till Kanata show up...her scene in the OP look..pretty serious and it didn't make sense why she wasn't there with her sister Sonata on that ship too.
there's crying scenes in the OP...possible hint of a darker future?
