"Denji's a poor young man who'll do anything for money, even hunting down Devils with his pet devil-dog Pochita. But his life gets turned upside down when he's betrayed by someone he trusts. Now with the power of a Devil inside him, Denji's become a whole new man--Chainsaw Man... As Quanxi and the members of the Special Division battle it out over Denji, the mysterious Santa Claus makes his move. But things are not as they appear, and nobody will be prepared for the darkness and despair about to be unleashed!"--Provided by publisher.
