The enemy: brain-eating monsters called Others. The mission: total extermination. Saved by the Other Suppression Force as a child, psychokinetic Yuito strives to repay his debt. Meanwhile, prodigy Kasane's dreams may hold the key to Earth's salvation.
Who controls the Others, and what is their ultimate goal? When Yuito and Kasane's hunt for answers leads them to a 2,000-year-old man-and across time and space-the truth only makes things more complicated.
