The 2023 film, focusing on a supernatural battle, does not explicitly portray LGBTQ+ characters or themes within its main narrative. While the broader series has a history of queer-coded characters, there is no direct evidence that this specific movie continues or revises such portrayals, resulting in no identifiable LGBTQ+ presence.

The 2023 film, New Dimension! Crayon Shin-chan the Movie: Battle of Supernatural Powers ~Flying Sushi~, does not include any explicit portrayal of transsexual characters or themes. The narrative centers on supernatural powers and conflict, without engaging with transsexual identity or community in any capacity.

The film primarily focuses on a conflict involving psychic powers between two male characters. Female characters, while present, do not engage in or win close-quarters physical combat against male opponents through skill, strength, or martial arts.

No characters in the film have an on-screen gender that differs from their established gender in the original Crayon Shin-chan manga or anime source material. Main characters retain their canonical genders.

All major characters, including Shinnosuke, Misae, and Hiroshi Nohara, are voiced by Japanese actors, consistent with their established Japanese ethnicity in the source manga. The film's setting in Kasukabe, Japan, accurately reflects its predominantly Japanese population. No race swaps are identified.
