Fred Carson is a broke office worker, earning barely enough to survive. When a ghost attacks him, he awakens the Ghost Attack System. The more he is attacked by ghosts, the stronger he becomes. From that moment on, his life motto changes from “work hard” to “get beaten harder.” The deadlier the ghost, the more powerful he grows—and the greater the rewards he receives.
