Once a humble office worker, Sei is now the Holy Saint of the Kingdom of Salutania, key to driving back the evil miasma that threatens its lands. What she enjoys most, however, are her peaceful days in the capital city working as a potionmaker. After helping to purify the forest near the capital, Sei hoped those days might return...but her reprieve is short-lived. A sudden acute shortage of potion ingredients sees her joining the knights of the realm on a journey to the Klausner Domain, rumored to be the home of secret potions found nowhere else! Series Overview: 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.

Could workaholic office lady Sei be a legendary Saint? Not according to the crown prince of another world who summoned her and quickly declared a different girl was the real Saint! That suits Sei just fine - she would much rather spend her days quietly helping people with her unbelievably powerful magic. But how long can Sei live her ideal life of leisure before her true nature is revealed?

BY THE GRACE OF THE HOLY SAINT With her workaholic life on Earth further and further behind her, Sei is truly coming into her own as the living Saint of the kingdom of Salutania. Experimenting with her unique holy magic, she finds new ways to fortify both herbs and potions with strength never before seen. It's a strength she may soon need to rely on, because the day is drawing close when she'll join the royal knights on their campaign to subjugate the wild monsters of the land. When the kingdom marches on a monster-haunted forest, it'll take all the powers of a Saint to make sure everyone comes home safe!
