Death at an Old Mansion

The story focuses on a heterosexual couple getting married. There are no characters who identify as transgender or non-binary, nor does the story critique the assumption that everyone is straight or cisgender.

A woman and her husband are the main characters. The woman's husband leads the investigation, but it is unclear if his role challenges traditional gender roles.

This Japanese film offers a non-Western perspective. However, there is no indication of a multi-ethnic cast or characters from different racial backgrounds.

The film follows a traditional locked-room mystery format. It emphasizes individual intellect and systematic investigation, without addressing secular or anti-Western themes.

There is no mention of characters with physical, sensory, or neurodivergent disabilities in the story.
