Is death really the end ? Seojin was supposed to die. One moment, he was an ordinary university student struggling through life in Seoul. The next, he was crushed by a speeding truck. Game over. Except… the system refused to let him go. > [ERROR: RESPAWN DETECTED][WARNING: ANOMALY IDENTIFIED][SCENARIO CLEANERS DEPLOYED] Now, Seojin wakes up in a foreign world with a glitched inheritance—the power of the Demon King, forcibly transferred to him through an unknown error. The system itself sees him as a mistake and sends nightmarish creatures to erase him. His abilities are unstable, his body is breaking apart, and something deep inside him is awakening. Hunted by both the system and those who fear his existence, Seojin must survive long enough to uncover the truth: Was this truly a mistake? Or was the Demon King’s corruption meant for him all along?
