The first volume in an eccentric manga series.
Denji is a poor young man who has never gone to school or even eaten jam. When his father killed himself, Denji inherited his father’s enormous debt to the yakuza, the Japanese organized crime. So now, Denji will do anything for money and food. He has sold off one of his eyes and a kidney. He has a pet devil dog Pochita who has a chainsaw on his head. So naturally, they hunt devils.
The comic is set in 1997, except for the existence of devils that attack humans and kill them. Devils can also possess dead humans. Most devils are evil and violent, but a few are more friendly, such as Pochita.
However, Denji and Pochita are ambushed. Earlier, Denji promised Pochita that if he died, Pochita could take over his body. Now, when Denji is near death, Pochita makes a pact with him. Pochita would merge with Denji if Denji showed the devil his dreams. Denji agrees and becomes a devil/human hybrid who can manifest chainsaws from his hands and head. The chainsaws come out when he pulls at a cord on his chest.
Soon, he is recruited to the Public Safety Division which protects humans from devils. Really, Denji’s choices are to join or be killed, so of course he joins. The Division has some devils working for it, as well as humans.
As you might expect, the comic is quite violent, centering on fights against devils. However, it also has dark humor and jokes. Denji’s goal is to have a normal life, including living inside, eating good food, and touching breasts. Joining the Division he gets to eat good food and live indoors, together with a crouchy male agent who doesn’t like Denji. His obsession with women’s breasts is a bit annoying. The Division has a couple of interesting characters, a brooding devil hunter who takes everything seriously and his opposite, a devil inside a girl’s body who doesn’t seem to be stable at all.
This seems like a good start to the series, introducing the world and the characters but leaving a lot of questions unanswered. Ends with a cliffhanger.
