The Saint's Magic Power is Omnipotent DVD Complete Season 1 + 2 English Dubbed

Season 1:
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.

Season 2:
Sei's status as the Saint is still something of a Salutanian secret, but it's one that won't last for long if she's not careful. That's by no means certain, since a trip to a port town puts her in a position where she could help if it wouldn't risk blowing her cover. Later, a visiting prince from another nation further jeopardizes her secret identity when he turns out to be desperately searching for a panacea to cure his mother's debilitating illness.
