The film follows a conventional heteronormative framework. There is no evidence of non-cisnormative identities or same-sex intimacy within the character dynamics.

Ran Mouri provides meaningful representation as a capable martial artist who offers physical protection. While female characters like Ai Haibara engage in independent dialogue, the social structure remains traditional.

The cast reflects a homogeneous demographic consistent with the series' Japanese setting. The luxury liner setting emphasizes socioeconomic class rather than a multicultural landscape.

The narrative utilizes a standard police procedural structure and celebrates high-status, capitalist leisure. Morality is presented through a traditional lens of justice and law enforcement.

There are no prominent depictions of visible or invisible disabilities. No neurodivergence or chronic illness drives the narrative or provides character agency.
