The Do-Over Damsel Conquers the Dragon Emperor, Vol. 7 (manga)

Thanks to Elentzia's betrayal, Hadis has been captured, and Jill is burnt to a crisp—or at least that's what would have happened, had she not been whisked to safety at the last moment by a black dragon! Jill will need to persuade it to lend her its power to save Hadis, but such a ferocious beast won't be convinced easily. Meanwhile, Hadis and Risteard desperately want to know why Elentzia has sided with Prince George...and the answer just might upend not only the royal family, but the entire empire!
