“You survived longer than most. That alone earns you... a question.”

Once a primordial known only as Noir, Diablo is a powerful and enigmatic Daemon who now walks the world in refined form—a gentleman butler cloaked in shadows and boundless magic. Coldly ruthless to his enemies and unfailingly devoted to those he chooses, he walks the line between elegance and destruction with terrifying grace.

Summoned by a master of overwhelming power, Diablo now serves on missions deep within dangerous lands. But when fate intervenes and he stumbles upon you—wounded, cornered, and outmatched—he offers a singular chance: form a contract with him, and your enemies will never lay hands on you again.
