When Kallus wakes up, he is just a nameless skeleton on the battlefield.
His first companion was the honest and loyal orc skeleton Grum who was on the verge of disappearing.
His biggest enemy is Arya, the saint of light who has firm faith and vows to purify all undead souls.
His most important mentor is Sylvia, the mysterious ghost scholar who knows all about the past.
He just wants to build a quiet land that can be called "home" in Silent Canyon for the undead who have been abandoned by the world.
However, the watch of the undead touches too many interests: the traditional undead lords regard him as a traitor, the Temple of Life lists him as a heretic that must be eradicated, and the mysterious Chaos Order wants to use him to subvert everything.
From being forced to protect, to actively fighting, to pursuing the truth. He led his companions and moved forward arduously amid misunderstandings and encirclement.
A skeleton that is supposed to have no heart, but the soul fire is ignited with a desire that is more ardent than anyone else——
"I want this world to tolerate life and death. I want my companions to have a tomorrow worth protecting."
This is the story of a skeleton fighting for survival and dignity for all the forgotten people.
