Ha-ri lived in Hyosan and attended the same school as her younger brother, Jang Wu-jin. She was one of the most skilled archers on her team. Ha-ri is shown to have a determined personality, as seen when she entered the school in hopes of saving her brother, but is also a bit harsh in some cases, as seen when she became angry with Dae-su after he confessed his feelings for her. She has shown herself to be an excellent archer, as most of the zombies she has shot at have been killed by her arrows.
