The film adheres to traditional heteronormative structures. The central relationship between Conan and Ran follows conventional romantic tropes. There is no exploration of queer identities or same-sex intimacy.

Gender roles remain relatively traditional within the mystery genre. While Ran Mouri is depicted as capable and protective, the narrative power dynamics center on the investigative prowess of male protagonists.

The cast is highly homogeneous, reflecting a localized Japanese setting. The film lacks intersectional casting or diverse character types to represent a broader ethnic or racial spectrum.

The story reinforces established social orders and respects traditional institutions like law enforcement. It prioritizes crime resolution and societal stability over critiques of systemic oppression or moral relativism.

The protagonist's condition of an adult mind in a child's body serves as a plot device. The film lacks nuanced representation of neurodivergence or visible disabilities with independent agency.
