Like Nadia, Jean is fourteen and an orphan, but he has a completely different personality and interests. He is very generous, patient, friendly, and devoted to the things he loves, which are his friends and the love for science. He is also genius inventor, in fact he is capable of creating complex machines at a very young age.  Despite being somewhat awkward when it comes to social graces around the opposite sex, Jean is genuinely well-behaved and is nice to everyone--even Gargoyle finds something to admire about his courage and cleverness.  He becomes Nadia&rsquo;s closest friend, and later on, her lover, as a result of the unlikely relationship that develops between them over the course of their around-the-world adventure.  Constantly loyal to Nadia, his compassion slowly transforms her as a person, inspiring her to be trusting and faithful in others.

In 1889, the world is on the pinnacle of great discoveries in technology. In mankind's grasp for the future, a sinister foe known only as Gargoyle, obsessed with restoring the former Atlantean empire to the glory it once held, begins his plans to take over the world. Nadia, with the help of a young inventor, Jean Raltique, and the mysterious captain Nemo of the submarine Nautilus, must fight to save the world from Gargoyle and Neo-Atlantis. Based on the Novel '20,000 Leagues Under the Sea' by Jules Verne.

A shorter, more streamlined version of Nadia called "The Nautilus Story", which all but eliminates the filler arc and concentrates on the struggle between Nemo and Gargoyle. Some scenes in the more pivotal episodes are cut as well. The compilation series was made by Hideaki Anno, who was said to have been dissatisfied with the final result of the TV show. The Nautilus Story was only released in Japan on VHS and laserdisc.
