――I don't want to die. I want freedom.

If that's what it takes, then I'll――willingly become a 'monster'.

A strange illness that causes ceaseless, intense pain throughout the body, eventually leading to death from exhaustion.

Afflicted by it, the boy endured years of suffering, then ended his life without even the luxury of feeling despair, unmourned by anyone.

And when he awoke again――the boy had become a 'Flesh Golem', the lowest-ranking undead, by the power of an evil necromancer.

The boy rejoiced at finally gaining the pain-free body he longed for, but soon realized that his situation was still one of control, not much different from when he was confined to a hospital room.

The world, however, would not leave the boy who simply sought peace alone.

The necromancer who resurrected the boy from a corpse using necromancy, named him End, and seeks to control him.

The Twilight Knights, who dedicate their lives to relentlessly pursuing and destroying all who belong to the darkness.

The Demon Lords who command numerous monsters, ruling over various lands and vying for supremacy.

His goals are survival and freedom. His needs are power and caution.

This is the story of a timid King of the Dead, who seeks freedom, sometimes fighting, sometimes fleeing, sometimes cowering, and sometimes hesitating.
