Bungo and Alchemist -Gears of Judgement-

Inside a labyrinthine library exist the souls of the world’s greatest writers. Now, these Alchemists must delve into the stories of old and do whatever is necessary to carry them out to their proper conclusions. Evil beings are hell-bent on destroying these stories, and the authors must believe in each other to stop them. There is only one way for this to end!
