About Nadia: The Secret of Blue Water

In a world on the brink of a new era, Nadia hides a secret that could reshape civilization. A mysterious girl with extraordinary abilities crosses paths with a clever teenage inventor named Jean Ratrique. Together, they are joined by Captain Nemo and his submarine Nautilus as the most unlikely team to save humanity. A powerful mastermind, Gargoyle, is hatching a plan to seize control and unleash Neo Atlantis, a hidden city rising from the depths. With danger around every corner, the group must outsmart their enemies, uncover ancient mysteries, and confront their own doubts as a vast adventure unfolds across sea and sky. The stakes keep rising as alliances shift and clues point toward a larger conspiracy.

Released in 1990 Nadia was guided by Yoshiyuki Sadamoto and Hideaki Anno with Hayao Miyazaki involved as a creator. The series draws on Miyazaki's concept and blends action packed storytelling with imaginative world building, mythology soaked visuals and character work.

Nadia stands out for marrying Jules Verne inspired imagery with anime style, creating a sense of wonder that still resonates with fans. The show helped elevate teamwork across diverse characters and showcased a bold, cinematic approach to TV storytelling that influenced later adventures from Gainax and its peers, shaping fan communities worldwide.

Critics and audiences welcomed the ambitious mix of science fiction, fantasy and drama, noting strong character dynamics and a cinematic tone for a TV series. The show explores themes of friendship and trust, the temptations of power, and the costs of progress, all set against a globe spanning, perilous adventure.

While Nadia earned enthusiastic fan support and generally favorable reviews, the data available does not show major awards or nominations for the series. Its lasting impact comes from its bold production pedigree, the collaboration of renowned creators, and its influence on later anime projects rather than any trophy wins.
