She and the Dragon King Strike Back

Iris is a lowborn servant girl who dreams of changing her fate, only to be declared classless during the awakening ceremony and humiliated by the noblewoman Liya. When demons attack Ashen Town, Iris loses her mother and falls into a ravine. There, she forms a life bond with a dying young dragon named Nova and unexpectedly awakens a knight's crest unseen on a woman for a century. From a servant who has never held a sword to a warrior fighting on the front lines, Iris rises with Nova at her side, determined to rescue her mother and strike back against the world that once kept her down.
