Similar main character and her traits.
Similar if not same themes and story. (futuristic, war, savetheworld, environmental)
Aoi Umi no Elfie seemed to me and feeled like ''Underwater'' Nausicaa.
Elfie is an aquatic version of Nausicaä set in a post-apocalyptic water world with strong ecological and pacifist message. Elfie is primarily made for children, it's straightforward story line with deus-ex-machina conflict resolution still has mina appeal. It's s still much simpler in terms of story telling, character depth and animation. Elfie has quality direction (on limited funding) by the director of "Dog of Flanders" (movie), as has Nausicaä (Team Ghibli).
