Jane Doe's name has two different references in it. The first and most obvious one is a reference to the term "Jane Doe", a placeholder name used in cases where a female individual's real name is either unknown or intentionally concealed (ironically, her Spoiler:New Eridu Public Security (NEPS) Consultant Card implies that her name really is Jane Doe rather than an alias). The second reference is found in her last name "Doe", which is what female fancy mice (domesticated breeds of common house mice) are often referred to as. Both of these references are fitting for Jane's character as she is a mouse Thiren with prominent ears and a tail, and because Spoiler:she works for NEPS as a consultant, specializing in criminal psychology and infiltrating dangerous groups.
