Saint's Magic Power is Omnipotent (Manga) – serie

Living the workaholic life in her mid-20s, Sei never expected she’d be summoned to another world, let alone obtain the power of a living Saint. And she especially didn’t expect to be totally ignored by the locals! While the kingdom desperately needs a hero, it turns out Sei was just the backup option. Left alone, she explores her newfound powers at the royal Research Institute, unraveling the mysteries of magic potions. As she helps the sick and the dying, her talents reveal themselves. Might Sei be the Saint this world needs after all?

Sei, a 20-year-old office worker, is whisked away to a whole new world. Unfortunately for Sei, the ritual that summoned her - meant to produce a 'Saint' who would banish the dark magic - brought two people over instead of one. And everyone prefers the second girl over Sei?! But this is just fine by Sei, who leaves the royal palace to set up shop making potions and cosmetics with her newfound magic. Business is booming, and this might not be such a bad life, after all... as long as her supposed Sainthood doesn't come back to haunt her.
