After surviving an abusive childhood, Shinya Kuroya learns a brutal rule: only the strong have the right to judge.

He climbs the darkest ladders of society, crushing every legend in his path, yet never finds the one man he seeks, his saviour. Even life as the adopted son of Australia's most powerful tycoon feels meaningless.
So he ends it.

Instead of death, Shinya is reborn as a Grim Reaper with the name Dark Silver, trapped at the bottom of Death’s hierarchy.

In a world where human strength is worthless and order is absolute, he sees a single chance worth taking—the possibility that his saviour stands at the top.

To reach him, Shinya enrolls in an elite Reaper academy where his kind are erased on sight. Hunted and outmatched, Dark climbs again. Manipulating allies and breaking enemies.

There, he meets Shade Naza, a monstrous freshman whose loyalty defies reason.

As they ascend, they strengthen their bond, aiming for a dominating future while still hiding their past.
