Transmigrated into a demon-taming world as the doomed noble lady Valery, she wakes to find herself poisoned, her rank fallen to F-class, with only three hours left before her demon-taming core shatters. Armed with her memory of the original novel, she finds the antidote and turns her fate around, taming one by one: Milo, the gentle healing white ram; Leon, the proud flaming lion king; Kappas, the serpent demon who was her childhood friend; Elian, the elegant and mysterious deer demon; and Drex, the legendary black dragon. Facing her sister's poisoning and betrayal and the invasion of the Riftwalkers, she rallies her five demons to guard the border and protect the people. With kindness and a sense of duty, she resolves the crisis, returns borrowed power to its rightful owner, and rises to become the realm's foremost demon tamer.
