Seojun Im was just a blacksmith in a world ruled by hunters.

Then his first “client” walked in.

Not a hunter.
Not even human.

Something… else.

From that moment on, they kept coming.

Urban legends.
Folklore spirits.
Things that should not exist.

All of them seeking him out with the same request:

“Forge it.”

Using materials carved from monsters and the unknown, Seojun creates weapons unlike anything the world has ever seen—artifacts that blur the line between tool and curse.

Hunters grow stronger.
Disasters are pushed back.
And his name begins to spread.

But power has a price.

Every weapon he forges leaves a mark.

His body changes.
His senses sharpen.
Something inside him is no longer human.

As catastrophic threats rise and unseen forces begin to clash, Seojun uncovers a truth he cannot ignore,

His family is trapped inside a cursed, unreachable realm.

To bring them back, skill won’t be enough.

He’ll need something greater.

Something impossible.

Because in a world where humans fear monsters,

he may have to become one.
