Min Eun-ji from "All of Us Are Dead" is a major antagonist in the first season of the series. Portrayed by Oh Hye-soo, Eun-ji was a severely bullied student at Hyosan High School, which led her to a deep state of depression. On the day of the zombie outbreak, her bullies took her to an under-construction building to humiliate her further. Although Lee Su-hyeok intervened to help her, she chose to stay with the bullies out of fear. After the apocalypse began, Eun-ji and Kim Cheol-soo stayed on the rooftop until she decided to go back inside the school to destroy Gwi-nam's phone, which contained compromising photos of her. She then went on a rampage, attacking anyone who tried to use the phones in the teacher's office. Eun-ji possesses enhanced strength and senses, including an enhanced sense of smell, after being partially infected with the Jonas virus. She also has the ability to heal herself, making her nearly invincible, and can tolerate a significant amount of pain. Her infection grants her a form of immortality, allowing her to survive longer than a typical human. Driven by a vengeful nature, Eun-ji uses her new abilities to terrorize the school and seek revenge on those who bullied her. Her story highlights the devastating impact of bullying and the dangerous paths it can lead individuals down.
