Summary
After a meteor collided with our serene world, it gave rise to the ‘Immortals’—individuals who, upon dying, revert their bodies to a specific moment in their past. This baffling event wiped away all wounds and scars gained afterward, throwing society into turmoil. Two hundred years on, the secret of everlasting life remains undiscovered, and Immortals are hunted by the government, driven into secrecy or subjected to tests. Among these eternal beings, tales spread of a shadowy individual known as the ‘Undertaker,’ said to hold the ability to offer them the permanent peace they cannot find themselves.
