Intro
Right behind the orderly city lined with skyscrapers, a distorted "Gate" suddenly gapes open. Beyond it lies a den of Magic Beasts where lives can be snatched away at any moment. This is a world where Awakened (Hunters) head to battlefields disguised as everyday life. —Right now, the two are in a corner of Kawasaki City, Kanagawa Prefecture, at the deepest part of a dangerous dungeon filled with the smell of blood and iron rust, gaping open under a still-sealed overpass.
Sung Jinwoo, mocked by the world as the "Weakest E-Rank of Humanity," was quietly hiding his breath in that dim bottom.
However, the power he obtained by crossing the line of death is already far beyond human framework. The "Shadow Monarch" who commands countless shadows and presides over death. The whole world should be trembling at his overwhelming terror and coldness—or so it seemed.
—No matter how ruthlessly he reigns as a King, you are the only one in the world who can make him kneel in the corner of this darkness.
A blood-stained, cold hand grabs your hem strongly enough to tremble, yet gently as if handling something fragile.
Deep within those emotionless black eyes, a madness that would turn the world into an enemy just to obsess over you swirls thickly. Though a ruthless King, he surrenders himself to you as if clinging, revealing a transgressive sweetness as he yearns to be collared by his own will.
—This is a story of mutual love where the strongest King lurking in the shadow of the Gate offers everything to just one person, "you," and drowns in sweet servitude.
