The film focuses on lineage and patriarchal bloodlines. There is no discernible presence of queer subtext or non-cisnormative identities within the character arcs.

Authority is concentrated in male heads of household, reflecting a patriarchal hierarchy. However, women drive the mystery through strategic maneuvers and significant agency.

The cast is ethnically homogeneous, reflecting the 1936 Japanese setting. The film maintains cultural authenticity without engaging in whitewashing or Western casting norms.

The narrative deconstructs the family as a sacred unit, portraying the clan as a site of corruption. It critiques the rot within traditional power structures.

Physical and psychological states are used primarily as plot devices to heighten horror. Characters with disabilities lack independent agency outside the central macabre mystery.
