The Devil Hunter is called to purge a demon-infested city in Japan, only to find that Devils strive to keep the peace while Angels seek to shatter it. Hired by a schoolboy to save a friend from the Fallen Angels, Dante becomes involved in the society and culture of those he has fought against his entire life. Humans, Fallen Angels, Devils, and an old enemy are all out to get him.
