Within one's Book of Fate is their destiny. Written by the mysterious Story Tellers, these books decide every small detail of one's life. Some Story Tellers, however, choose to interfere with the stories of others rather than write their own. These malevolent beings are known as Chaos Tellers, who seek to ruin stories by overwriting the Books of Fate.

Ex, Reina, Tao, and Shane were born with blank books. Ostracized by society due to this abnormality, they abandon their respective stories in search of better lives. In the vast unknown, they encounter famous fairy tale characters such as Cinderella, Momotarou, and Snow White. All the while, they work to subdue the Chaos Tellers and return peace and order to the stories.
