From Yen Press:
Wrongly executed for crimes he didn’t commit, a former detective is given a second chance at life. To earn that chance, though, the man now known as Ash must use the supernatural abilities with which he has been infused to prevent the deaths of other innocents. But is Ash willing to dedicate himself to helping others, or is his thirst for vengeance against those who destroyed his life and his loved ones too powerful to ignore?
