Chainsaw Man

After his father's death, Denji is left with a massive debt and forced to work as a Devil Hunter for the Yakuza just to survive. His only companion is Pochita, a small Devil with a chainsaw growing from his head, who helps Denji hunt Devils and pay down his debt. When the Yakuza betray Denji and leave him for dead, Pochita sacrifices himself to save him, becoming Denji's heart in the process. Reborn as a human-Devil hybrid with the ability to transform into Chainsaw Man, Denji sets out to build the ordinary life he has always dreamed of, even as his newfound powers draw him into the dangerous world of Devil Hunters.
