The Saint's Magic Power is Omnipotent

Synopsis

For generations, the kingdom of Slantania has been plagued by a miasma that spawns monstrous creatures, threatening the land. The Order of Knights fights valiantly against these dangers, but the Grand Magus seeks divine aid by summoning a sacred maiden known as the "Saint" to destroy the monsters and restore peace. One evening after her workday ends, Sei Takanashi is suddenly transported by magic to a strange realm. Upon arriving in Slantania, she learns that the Grand Magus accidentally summoned two Saints—herself and a brunette girl. Since only one Saint is needed, the prince selects the other woman for the role, freeing Sei from any official duties. Choosing to explore her new environment, Sei joins the Medicinal Flora Research Institute, a facility focused on studying herbs and creating potions. During her time there, she meets the leader of the Third Order of Knights. Unbeknownst to Sei, her hidden abilities as a Saint continue to affect her life in this unfamiliar world.
