The Saint's Magic Power is Omnipotent

Sei was once a workaholic in her mid-20s, never expecting to be summoned to a different world or bestowed with the power of a living Saint. However, despite her new status, she was surprised to find that the locals didn't seem to notice her at all. The kingdom was in dire need of a hero, but Sei was just a second choice option. Having no one to rely on, she embarked on a solo journey to the royal Research Institute, where she discovered her newfound abilities. As she studied the secrets of magic potions, Sei's exceptional skills were revealed as she assisted the sick and dying. Could this be the answer to the world's prayers that Sei was the long-awaited Saint?
