The Bratty Lady Throws a Tantrum

Duke Heros Archeon believed he had saved the world from ruin when he struck down Sellus, a fearsome black dragon. Yet his triumph was far from absolute. Instead of fading into oblivion, the slain beast’s soul transmigrates directly into the body of Daphne Archeon—the duke’s own daughter, who is infamous for her cruelty and petulant nature. Miraculously, the dragon’s presence within her proves to be an unexpected upgrade, tempering the girl's worst traits. Now inhabiting this frail human form, Sellus assumes control of Daphne’s life with a singular, vengeful purpose: to relentlessly train her body until she possesses the strength to slay the very father who defeated him. However, the path of vengeance grows complicated as new dangers emerge. When sinister dark mages rise to threaten both the Archeon family and the kingdom itself, Sellus discovers that occupying Daphne’s body comes with unforeseen emotional entanglements. Despite being a reincarnated dragon harboring murderous intent toward the duke, a strange sense of righteous duty begins to ignite within her bratty little heart, forcing the former calamity to grapple with an unfamiliar desire to protect the people she once intended to destroy.
