As a second society, women are always discriminated against in the workplace. In Japan, formal women employees are merely an office decoration (shokuba no hana) and occupy lower positions, making it impossible for them to hold managerial or stakeholder positions. This study aims to present the figure of a lone-wolf woman who realizes her potential in the world of masculine worker masculinity. The main female character portrayed by Ryoko Yonekura in Doctor X, Legal V: Ex. Lawyer Shoko Takanashi, and The Journalist takes the research object. The research took the form of a descriptive-qualitative study, which were subsequently analyzed using existentialism feminism from the Simone de Beauvoir. According to the findings of the study, the three primary characters play a dominant role at work and outperform men on challenging projects. Nevertheless, as objects, the three figures remain marginalized in the job hierarchy and confront threats in the workplace. Furthermore, the reader's response demonstrates that a work environment dominated by patriarchal values and masculinity is not a secure place for intelligent women, but rather illustrates the utopia that women can have the same or even greater cognitive abilities than men in the workplace.
