Around 50 years ago, after the Korean War, Demon World Gates appeared abruptly all over the world.<br>
Through the Gates, Demon creatures appeared. These otherworldly beings, utterly impervious to modern weaponry, rained destruction across the world.<br>
Just when all hope for humanity was lost, the "Masters" awakened: humanity's one chance for salvation.<br>
With the appearance of these entities, the world began to change rapidly.<br>
<br>
Fast forward to 50 years later-<br>
We meet Gang Kyu Sung, who had worked for a small company as a deputy who could never catch a lucky break nor even got promoted.<br>
That is, until he happens to awaken as a Master...?<br>
<br>
A Rank 5 Master who had once been ignored and scorned-<br>
Thus begins the uprising of a man who works his way up from the bottom!
