I've known the Princess Tutu anime since I was in Middle School, I didn't know the anime was based on a manga. I'm wondering if the ending to the manga is better than the anime ending because I didn't like how the anime ended with her being a duck in the end and never being human again and I thought that was sad :( I'm also curious if the manga is a lot better than the anime.
