Mu, the world that exists parallel to our own. It is a world that harbors shadowy manifestations of people's feelings called Nullities. One day, Fragments, dimensions that connect Mu to the real world, begin manifesting in Shiroki City. With that comes disappearances of people who never return. Kazuki Arata, like most people, dismisses the explanations for those disappearances as urban legends. However, with the appearance of the transfer student Sayaka Uehara and his unexpected trip to a Fragment, the wheels of fate begin to turn on this new chapter of his life.
