Black company Artemis Corp is a unique enterprise with a president who constantly concerns himself with employee health. Office worker Amu, employed at this company, commutes daily between home and work, dressing in a simple uniform of a miniskirt and pantyhose. The president subjects Amu to an unusual training regimen—forcing her to step on acupressure mats. Initially, Amu endures the pain and continues stepping on the mat, but soon even harsher tasks are imposed. She is made to jump rope, and the training grows increasingly severe. While maintaining her position as an employee, she is gradually stripped of basic human treatment, pushed closer and closer toward being treated like a dog.
