The film lacks prominent LGBTQ+ characters or non-cisnormative identities. Interpersonal dynamics follow traditional heteronormative structures common to the genre.

The story centers on Rin Okumura, a male protagonist who drives the plot. Female characters like Shiemi Moriyama primarily occupy supportive or academic roles.

The cast is largely homogeneous, reflecting the specific cultural setting of the source material. There is no intentional racial blending or diverse casting.

The narrative utilizes the hierarchical Exorcist Order as a stabilizing force. Conflict arises from those acting outside this established institutional authority.

Characters lack visible or invisible disabilities. The plot focuses on supernatural lineage and powers rather than nuanced explorations of physical or neurodivergent experiences.
