For centuries, the people of Slantania have been living under a cloud of miasma that causes monsters to wreak havoc across the world. When the Order of Knights can no longer control these creatures, the Grand Magus calls upon the legendary "Saint" to eliminate them and restore peace. On her way home from work one evening, Sei Takanashi is pulled into a different realm by a magical force. Upon arrival in Slantania, she learns that the Grand Magus mistakenly summoned two Saints-Sei and a brown-haired girl. Since only one holy maiden is needed, the prince declares the other girl as the Saint, leaving Sei to fend for herself. In her quest for knowledge, Sei visits the Medicinal Flora Research Institute, which specializes in studying herbs and potions. There, she encounters the commander of the Third Order of Knights. As she continues to hone her abilities as a Saint, she will face new challenges and opportunities in this strange new world.
