The Saint's Magic Power is Omnipotent

Sei, a twenty-year-old office worker, is abruptly transported to another world through a summoning ritual intended to call forth a single "Saint" capable of eradicating dark magic. However, the spell unexpectedly pulls two individuals across dimensions instead of one. To Sei's dismay, the kingdom quickly favors the other girl, showering her with attention while leaving Sei entirely overlooked by the royal court. Rather than feeling slighted, Sei embraces this dismissal as an opportunity for freedom. She quietly departs the royal palace and begins utilizing her newly awakened magical abilities to craft potions and cosmetics. Her entrepreneurial venture proves remarkably successful, allowing her to build a comfortable and independent life far removed from the pressures of the castle. As business flourishes, Sei finds genuine contentment in her peaceful new routine. Yet, beneath the surface of her thriving enterprise, a lingering uncertainty remains. The dormant power tied to her unexpected summoning still exists, and she must navigate her quiet life with the constant awareness that her true status as a Saint could eventually resurface and disrupt everything she has built.
