Yeok Cheon-myeong had already beaten a notoriously difficult martial arts game on Chaos difficulty.

Then he woke up inside its world as a low-ranking vagabond in the Murim Alliance.

The martial world he remembered from the game is already strange enough, but nothing prepared him for the Ghost Soul Villa, a deadly anomaly that nearly kills him before he manages to absorb its essence by burning away his own life force.

That incident draws the attention of the Murim Alliance's secret Management Records Bureau.

Now tasked with investigating the world's bizarre anomalies, Cheon-myeong has found himself in a job where strange rules can mean the difference between life and death. With his constitution damaged and his survival increasingly dependent on absorbing demonic anomalies, even solving the next case may come at a price.
