Denji is a loser who will do literally anything for money, due to inheriting an enormous debt to some local Yakuza Loan Sharks after his father seemingly committed suicide when he was a child. This includes hunting Devils, dangerous Anthropomorphic Personifications of human fears that randomly appear in the world on a regular basis. Having no friends other than his pet Devil Pochita, a dog-like creature that is also a chainsaw, and having sold several of his own organs now to survive, Denji seemingly has no hope of a future. But even so, Denji still dreams of living a better life.
