The film lacks any visible presence of LGBTQ+ characters or non-cisnormative identities. The social framework centers on a heteronormative, traditionalist peer group without engaging in queer subtext.

The narrative adheres to conventional gender hierarchies. Shizuka’s agency is largely defined by her relationship to the male-dominated group, while masculinity is expressed through aggression and underdog tropes.

Set in prehistoric Japan, the film presents a culturally homogeneous cast. It focuses on a singular, ethnically consistent perspective that offers limited intersectional breadth.

The story celebrates historical continuity and traditional values like friendship and family. It prioritizes social cohesion and the stability of the group unit over any subversive critiques.

There are no prominent depictions of physical or neurodivergent disabilities. Characters are presented through a lens of able-bodied capability without integrating specific sensory or mental health narratives.
