Dream, a dream, you want to escape from.When your own dreams are no longer a safe haven for your mind and they're no longer confined within your sleep, trouble can only arise. For Yumeji Fujiwara his unique ability to predict and enter other peoples' dreams is causing him some trouble, as he finds himself the focus of an army of cats belonging to an ominous dream demon. But luck is at hand with one, Merry Nightmare, to the rescue! Merry, a dream demon, has unseeingly crossed over from the dream world to reality with no memory of how and why. Coupled only with the knowledge that she wants to go back, Yumeji offers his aid to help return her home. However things just might not be all that easy when Merry is not the only demon to have crossed over to reality and nor do they have the best of intentions either.
