Nam On-Jo

Nam On-jo is described as a calm and mature person. She consistently helps friends survive the zombie crisis. Nam On-jo protects her friends by attacking an infected teacher who rushes into the broadcasting room. In addition, she even performs CPR for her friend Lee Cheong-san when he faints. After Nam On-jo survives the zombie crisis, her friend Park Mi-jin brings her a notebook. The notebook is a diary that Oh Joon-young’s recorded about what happened in the school during the zombie crisis. Based on what’s written in the notebook, Nam On-jo publishes a book about her experience at Hyosan High School. That book becomes a background story for “All of Us Are Dead.”
