The film follows traditional romantic structures centered on Harlock and Miya. There is no explicit depiction of non-cisnormative identities or same-sex intimacy, remaining within a conventional heteronormative framework.

Female characters possess significant agency and technical competence. Mimay serves as a vital narrative component rather than a passive figure, subverting the typical damsel in distress archetype through her autonomy.

Terrestrial race is superseded by species-based dynamics between humanity and the alien Illumidus Empire. The cast lacks modern intersectional variety but focuses on a unified, displaced human identity.

The story elevates anti-authoritarianism by framing pirates as heroic outlaws against an oppressive empire. This resistance against imperialist hegemony offers a framework that can be viewed through a post-colonial lens.

There are no prominent depictions of visible or invisible disabilities that serve as central narrative drivers in the film.
