The film lacks explicit depictions of non-heteronormative identities or same-sex intimacy. The narrative focuses on the mystery of Kaburagi's identity and his connections to Sayaka, Kazuya, and Mai.

Female characters like Sayaka and Mai serve as essential nodes in the protagonist's journey. Their roles as primary witnesses help shape the protagonist's perceived identity, moving beyond purely male-centric investigative frameworks.

As a Japanese production, the cast and setting reflect local demographic norms. There is no explicit evidence of diverse ethnic blending or color-blind casting within the domestic setting.

The story avoids a binary good versus evil framework by emphasizing moral relativism. It critiques institutional authority by questioning the detective's pursuit of a singular, objective truth.

There is no mention of characters navigating physical, neurodivergent, or mental health disabilities within the narrative.
