Famous writers throughout history find themselves being reincarnated by a mysterious, unseen entity known as the Alchemist. With their souls confined and bound to an expansive library, they are tasked by the Alchemist to jump into books to purify the pages of monsters called Taints. Along the way, they must also rescue and recruit fellow authors trapped within the very stories they themselves had written. Although the writers take on new and powerful forms for this endeavor, some still maintain a semblance of who they once were, while others struggle to remember their pasts and the works they had penned. Despite there being no apparent end to their grand mission, they remain committed to the cause in hope of resolving the mystery behind their collective resurrection as well as questions that have haunted their former lives.

As he and his comrades strive to fulfill various missions and other assorted tasks in order to keep their small company alive, they will uncover the mystery behind their former leader's sudden departure.
