The film lacks explicit depictions of non-cisnormative identities or same-sex intimacy. While the shared trauma of the soldiers might offer subtle explorations of intimacy, there are no clear queer-coded character arcs.

The narrative is centered on a male-dominated military environment. It reinforces traditional masculine archetypes through wartime duty and lacks female characters with agency or subversion of gendered power dynamics.

The cast is ethnically homogeneous as a Japanese production. However, the focus on rank-and-file soldiers provides a nuanced look at class and social stratification within this specific ethnic context.

The film challenges nationalist frameworks by portraying soldiers as victims of a failing state. It disrupts patriotic tropes through a systemic critique of institutions and state-sanctioned morality.

The prison setting inherently explores psychological distress and the mental health implications of confinement. It is unclear if trauma is portrayed with agency or used merely as a plot device.
