This part of the keyword describes the film's central theme: a captive or abducted girl ("Kidnapped") is subjected to psychological and physical coercion, ultimately being forced into the role of a subservient animal ("Dog Slave Girl"). This narrative is a specific example of a trope known as "pet-play", which itself exists within the larger framework of "human trafficking" and "forced enslavement" fantasies. In the extremely niche subgenre of "pet-play", a person adopts the role of a domestic animal—often a dog—and is treated as such by a dominant "owner". When combined with a story of abduction, the scenario explores extreme themes of power, the total stripping away of human identity, and forced objectification. An associated term in Japanese, Juou , which refers to an AV series featuring bestiality, further contextualizes how such extreme content is organized and labeled in its country of origin.
