The film contains no discernible LGBTQ+ characters or explorations of non-heteronormative identities. The romantic subplot between Glenn and Miss Namikawa follows a traditional, heteronormative trajectory.

Agency is concentrated within a male-dominated scientific and military command structure. Female characters like Miss Namikawa are largely supportive or reactive to the central male protagonists.

The cast is predominantly Japanese, reflecting the film's cultural origins. It avoids the whitewashing common in Western cinema of the era but does not pursue multi-ethnic representation.

The narrative celebrates scientific progress and the preservation of established institutions. It presents a binary moral framework between the protectors of Earth and the manipulative Xiliens.

There are no prominent depictions of visible or invisible disabilities. Characters are presented as able-bodied agents of action without disability serving as a plot device.
