Broke young man + chainsaw dog demon = Chainsaw Man!

Denji was a small-time devil hunter just trying to survive in a harsh world. After being killed on a job, he is revived by his pet devil-dog Pochita and becomes something new and dangerous—Chainsaw Man!

As Quanxi and the members of the Special Division battle it out over Denji, the mysterious Santa Claus makes his move. Things are not as they appear and nobody will be prepared for the darkness and despair about to be unleashed!
