Pretty was one of the ace officers of a powerful secret organization on Earth who had abilities to control their Rentom or a person's souls. Betrayed by her own uncle, she was sacrificed in a ceremony to take her abilities. Just when she was about to be killed she was taken accidentally by a mysterious force and transported her soul in a different world she once read in a book.  There were supposed to be only eight people to be transmigrated to replace the eight vacant bodies of eight major characters in the book. But a ninth one was accidentally added in error.  Pretty, who was clueless to know that she was not the only one transmigrated, decided to only wait for her new world to be better by the protagonist of the book, a lost princess destined to be the ruler of the kingdom, and the lackeys that helped her. Not knowing eight other people had already replaced the souls of these characters. Pretty knew what happened in the book, so she decided to find a corner and stay there. But the future that the book told was different from what she's experiencing now. The world of Sologea was on the verge of an apocalypse. Organization and monsters, both creatures and humans, not mentioned in the book started appearing and the legend of Eight Impenetrable Kingdoms was jump started for a reason unlike in the book.  Now, she had a world to save but the other eight transmigrators thought they were god's chosen and decided to take the future in their own hand causing more apocalypse and problems.  She just wanted to live peacefully. But a greater conspiracy and legend awaits her and if she couldn't help it, god forbid, she wants nothing of it.
