Doraemon the Movie: New Nobita and the Castle of the Undersea Devil

No LGBTQ+ characters or same-sex relationships appear. The narrative centers on a straight childhood friend group navigating an underwater adventure without queer subtext or representation.

The core group is all boys, with Shizuka as the sole female member. She joins the adventure, but the plot is driven primarily by male characters and the new male ally, Eru.

The cast is entirely Japanese, reflecting the film’s domestic setting and audience. The underwater Mu Federation is fictional, offering no real-world racial diversity or cross-cultural casting.

The film promotes teamwork, friendship, and curiosity. It frames the underwater people’s initial hatred of surface dwellers as a prejudice to be overcome through trust and cooperation.

No characters with physical or mental disabilities appear. The story relies on sci-fi gadgets and fantasy elements rather than disability narratives or inclusive casting.
