Chainsaw Man Vol 1

Broke young man + chainsaw dog demon = Chainsaw Man!

Denji’s a poor young man who’ll do anything for money, even hunting down devils with his pet devil-dog Pochita. He’s a simple man with simple dreams, drowning under a mountain of debt after inheriting his deceased fathers' debt to the yakuza. After being killed on a job, he is revived by his pet devil-dog Pochita and becomes something new and dangerous. Now with the power of a devil inside him, Denji’s become a whole new man—Chainsaw Man!
