After years of humiliation, a college outcast opens his eyes in the body of a feeble low-tier reptile, discarded by the ruthless heiress who owns him. With an ability that lets him grow stronger by consuming anything in his path and only forty days before civilization collapses, he claws his way toward dragonhood, uncovers a hidden scheme, and must decide whether revenge is enough—or if this broken world deserves his salvation.
