The narrative lacks explicit LGBTQ+ characters or storylines. It focuses primarily on maternal bonds and childhood friendships within conventional social structures.

The film centers on female experiences, specifically through the protagonist and a grieving mother. However, these roles rely on traditional emotional archetypes common in psychological horror.

Set in rural Shikoku, the cast and setting are ethnically homogeneous. The film reflects the specific demographic reality of its Japanese regional context.

Traditional Japanese spiritualism, including seances and exorcisms, drives the plot. These elements serve as genre devices rather than critiques of religious or institutional norms.

Mental health is addressed through a mother's grief-induced instability. This portrayal risks utilizing the 'madwoman' trope to fuel supernatural tension.
