Chainsaw Man is a combination of action, dark comedy, and fantasy. I bought this first volume brand new.
Review:
When Denji was a kid, his father committed suicide, leaving behind an enormous debt, which yakuza then expected Denji to pay back. On his own, Denji probably would have died. However, he happened upon a wounded devil that looked like a little dog with a chainsaw sprouting out of its face. He offered it his blood in exchange for a contract, and that's how Denji's friendship with Pochita began.
Even with Pochita's help, however, Denji occasionally had to resort to selling his own body parts in order to make the payments yakuza demanded from him. And eventually even that wasn't enough - the yakuza attempted to make their own contract with a devil and became zombies as a result, reducing both Denji and Pochita to pieces tossed into a dumpster. With the last of his strength, Pochita made another contract with Denji, becoming his heart in exchange for getting to hear more of Denji's dreams.
The first person to encounter the newly changed Denji is Makima, a public safety devil hunter. She agrees to add him to a public safety devil hunting squad, but only if he never quits. If he does, she'll kill him. Denji is just happy that someone is finally being slightly nice to him. It helps that that someone is a pretty woman.
