Yuno Kashiwagi (Inmate 003) is a calm and deceptively pleasant prisoner whose role in MILGRAM revolves around her cynical view of love and society. On the surface, she acts like a friendly, trendy, and normal young woman, but she uses this cute persona as a shield to hide her true, cold nature. In the trials, Es must investigate her past as a sugar baby and analyze her connection to a controversial abortion, trying to find the line between her victimhood and her guilt. Her presence in the prison creates a tense atmosphere, as her complete lack of remorse and sharp intuition make her a difficult inmate for the judge to read and control.
