Yama, the King of Hell, decides to retire in search of happiness. However, his plans for reincarnation are delayed when his successor, Harry, deserts his post to chase a mysterious goal in the human realm. With the help of the undertakers—humans who can harness the power of the Underworld—Yama strives to restore order and return everything to normal. Will Yama navigate the cycle of rebirth without faltering, or will the shadows of his past disrupt his journey? One thing is certain: there will be hell to pay.
The underworld has crumbled. In the desolate land where rivers of blood once flowed, clear water now runs, and the cauldron that once boiled souls has grown cold. The retired King of the Underworld, seeking his own happiness, aims to follow the path of reincarnation. Yet, due to the chaos in the Underworld and the disappearance of his successor, he cannot proceed on this path.
To become a god in the human world and to track down the missing successor, the King of the Underworld descends to Earth. But the human world is in turmoil due to the escape of souls from Hell, orchestrated by his successor's cunning plan. The King of the Underworld teams up with the 'Guardians of Life,' who protect humans, using the power of the Hell's ledger. Together, they struggle to capture his successor and restore the world to its original state. Will the King of the Underworld manage to safely walk the path of reincarnation?
