Sei Takanashi

Sei Takanashi (小鳥遊聖, Takanashi Sei) is the main character of Seijo no Maryoku wa Bannou desu. She is a workaholic office lady in her twenties who was summoned as a saint to another 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.
