The Secret World of Arrietty is an animated fantasy film centered on the lives of tiny 'Borrowers' and their struggle for survival. The narrative does not feature any identifiable transsexual characters or explore themes related to gender identity or transition. Consequently, the film has no discernible impact on the portrayal of transsexual individuals or related topics.

The film features Arrietty, a small Borrower, who primarily uses stealth and evasion to navigate the human world and escape capture. While she faces threats, including the human housekeeper Haru (female), there are no instances where a female character defeats one or more male opponents in direct physical combat.

The film is an adaptation of Mary Norton's novel "The Borrowers." All major characters, including Arrietty, Pod, Homily, and Sho, retain the same genders as established in the original source material. No instances of gender swapping are present.

The characters in Mary Norton's original novel, "The Borrowers," were not explicitly defined by human racial categories. As such, the animated film's portrayal does not constitute a change from an established race.
