Instead of gaining powerful combat magic, she discovers an unusual ability: she can turn terrifying monsters into tiny, lovable pets. Legendary creatures such as dragons and Fenrirs instantly become affectionate companions while retaining their overwhelming strength. Mistaken for the prophesied Saintess, Tōru is welcomed by the handsome Knight Commander Zylard, but another Saintess has already appeared, creating political tension within the kingdom. As more disaster-class monsters appear, Tōru's unique power proves to be the key to protecting the kingdom. Blending wholesome comedy, adorable magical creatures, light romance, and fantasy adventure, the story follows her dream of living a peaceful slow life—despite constantly attracting the world's strongest monsters.
