One day, Sei, an office lady in her twenties is summoned to another world as its “Saint”.
Using her love for plants, she started working at the medicinal flora research institute, but thanks to her workaholic nature and her “Saint power”, she kept making potions that were 50% more potent one after another.
On top of that, during a monster extermination trip, she invoked a purification magic of tremendous power, and Sei’s reputation saw a titanic rise!
After being officially recognized as the “Saint”, people started admiring her as the savior of the Salutania Kingdom.
She is watched over and supported by Johan and Jude from the research institute, Yuri the Grand Magus, and Albert the Winter Knight, who is attracted to each other with Sei, but is still less than a lover.
Even after becoming the most important person in the kingdom, Sei still immerses herself in research. However, her relationship with Albert grows deeper, and her love life could take a new turn?!
