The Saint’s Magic Power is Omnipotent (Light Novel) Vol. 8

HEARTS ENTWINED For over two years, Sei has traveled the lands of the Kingdom of Salutania to purify the miasma and subdue the monsters that plague her new home. However, while Sei may soon bring this chapter of her life to a close, the next has already begun. The time has come for the Saint to choose her future husband. While Sei’s heart has long since belonged to a certain icy-eyed knight, many others seek her hand in marriage. Now Sei and Albert must find a way to confess their feelings before a certain noble’s ambitions tear them apart forever.
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.
