U Yeon-Hui is the number one hunter in the world who can kill hordes of monsters singlehandedly, but she has one problem. She doesn't want anyone to know! To live a normal life, she makes sure to hide her face when she enters dimensional gates and clears dungeons. But when her cover gets blown one day, she becomes the center of a bidding war among the world's top guilds. As she goes on more perilous missions with her identity exposed, she wonders if she'll ever get to live a normal life again.
