The film adheres to heteronormative relationship structures. There is a lack of explicit non-cisnormative gender identities or same-sex romantic depictions within this installment.

Female characters like Ran Mouri demonstrate significant physical competence and intellectual resilience. While they avoid purely submissive tropes, the film does not fundamentally deconstruct traditional gender hierarchies.

The cast is largely homogeneous, reflecting the domestic Japanese setting of the military vessel. The narrative does not prioritize racial blending, though it avoids harmful racial caricatures.

The plot explores tensions between civilian life and military authority. It emphasizes the fallibility of large-scale institutions when faced with internal threats and systemic vulnerabilities.

There is limited focus on visible or invisible disabilities. Characters are defined by their utility to the mystery rather than neurodivergence or chronic illness.
