"Any who stand before me are but mere sinners."
Hell has failed.
Where blood should flow, clear water now runs, and the pot that used to boil the dead has long since gone cold.
Retired as the "King of Hell," Yumla sought the path of reincarnation for his own happiness. However, due to the chaotic state of Hell and the disappearance of his successor, "Tulbo," he cannot walk the path of reincarnation.
To become a god in the human world, Yumla descends upon the human realm to pursue Tulbo, who causes chaos by vanishing from both the human world and Hell. But the human realm is in turmoil due to the souls who escaped from Hell through Tulbo's schemes.
Yumla joins forces with the "Guardians," who protect humans using the power of the Book of Hell, to capture Tulbo and restore order to the world.
Will Yumla be able to safely walk the path of reincarnation?
