The Goddess has been summoning and reincarnating a broad range of people in order to stop the Hero from destroying the world, but they all seem to have ended in failure. However, all the reincarnations that had been conducted until now were for the purpose of gathering data. With the data she has gathered, she summons the person most likely to stop the Hero.
