Phantom Dust

A strange dust from space has settled on the Earth, causing its inhabitants to lose their memories. Worse still, prolonged exposure to the dust has caused many of them to turn into monsters. Fearing the dust, the crumbling remains of humankind have been forced to dwell underground. However, a small number of gifted individuals dubbed "Espers" are able to harness the power of the dust and bend it to their wills, giving them an advantage on the surface. Driven by a shared memory of an area known only as the Ruins, these Espers seek to reclaim humanity's lost memories, carrying out missions given to them by their strict and mysterious organization. Complications arise, however, when two Espers with amnesia are rescued by the organization. A conspiracy begins to unfold as the two fight to uncover the truth behind their missing memories—memories that may contain humanity's darkest secret.
