Nidaime Seijo wa Tatakawanai

Meryl Klein was born the daughter of the strongest "Saint" and exorcist in the land. Because of her lineage, she believed without a shadow of a doubt that she possessed power surpassing even her mother’s. Arrogant and completely untrained, she heads out for her very first mission.

Faced with a terrifying demon that could crush her in an instant, Meryl commands it to "Begone!" But the miracle she expects never happens. In that moment, she realizes the horrifying truth: she possesses absolutely none of her mother’s power.

In this desperate situation, the demon utters a single phrase: "I have killed no one." Meryl sees a way out. To hide her own incompetence, she has only one option: prove the demon's innocence and avoid a fight at all costs.

Thus begins the legend of the weakest girl, who would come to be hailed as the "Saint of Non-Violence."
