The world has changed and so have the people.

December 31st, 2016 – the day before New Year's. Kim Taehoon was just casually shopping for groceries at the large store. Monsters suddenly appeared out of thin air. With the highly trained skills that he had gained from his previous occupation, he starts to hunt the monsters down and manages to win, saving countless people who were also at the mall.

But there are more and they don't stop coming. Will he be able to survive until the end? Will he be able to beat the countless monsters that only seem to get stronger? And will it just be monsters that he has to worry about?

The journey of Kim Taehoon, The First Hunter, begins.
