It's a better girl who got pulled into another world with another girl to be a goddess but they chose the other girl she was just sent to work in the castle then she winds up becoming kind of like a pharmacist but she's really good at Magic and she kind of looks out of it like a video game that she used to play so she tries to level up all of her stats but she wasn't being really good at making potions
I think it is “The Saints magic power is omnipotent.” :)
