Cipher of the Black Iron

When Soichiro Kurogane, patriarch of the Asahi Federation's most feared zaibatsu, dies, his encrypted will ignites a war among his heirs. To claim the empire, they must solve a digital labyrinth that guards the family's darkest secret—a massacre in wartime Haedong buried within the code itself. Hiroto, a disgraced cyber-forensics heir, soon realizes the curse is not a ghost but a self-replicating algorithm that infects each generation. The deeper he hacks into the truth, the more he sees his own reflection twisting into the very monsters who built the dynasty. In this psychological maze, every key unlocks a more terrifying version of himself.
