The Chainsaw Man anime follows Denji, a poor young man who works as a devil hunter with his chainsaw-dog devil companion, Pochita, to pay off his deceased father's debt to the Yakuza. Betrayed and killed by the Yakuza, Denji is resurrected by Pochita, who sacrifices himself to become Denji's heart, turning him into a chainsaw-human hybrid called "Chainsaw Man". Denji is then recruited by Makima into the Public Safety Devil Hunters, where he lives a comfortable life for the first time, struggling to form relationships and find his dreams while fighting devils.
