やり直し令嬢は竜帝陛下を攻略中

Jill Cervel—fiancée of the crown prince Gerald der Kratos and known as the "Lady Goddess of War"—is being hunted down by the same country she swore to protect. Betrayed by her betrothed, she is framed as a traitor and imprisoned. In her last moments, Jill is filled with regret, but just as death approaches, she awakens six years in the past. This time, she will not be a mere pawn. Now as a 10-year-old girl, Jill resolves to escape her imminent engagement to the prince. To this end, she jokingly professes her love to the 19-year-old dragon emperor Hadis Teos Rave, who will one day stain the land in blood due to madness. But against all expectations, he accepts! In contrast to the tyrant from Jill's memories, the Hadis of this time is a kind albeit unfortunate emperor. Can Jill prevent Hadis from descending down the same dark, villainous road, or is he bound to an inevitable future? [Written by MAL Rewrite]
