"Hawk Eye" Seo Ji-na was once an ace sniper in the army and had a 2,937-yard record kill under her belt. Because of her, her team also took on the moniker of the "Hawk Eye" team. She has always considered herself to be cold and stone-hearted, and believes that calmness and rationality are the keys to survival and victory in battle. But it was after the Zombie outbreak that her heart was truly tested for the first time.

In the face of the Zombie attack, her comrades fell one by one until she was the only one left. She wondered about the meaning of life after repeatedly witnessing the deaths of comrades and enemies. She sealed off her feelings, but continues to seek the meaning of her existence in this post-apocalyptic world. She knows that death will come for her one day, but she hopes to find her humanity again before then.
