Chainsaw Man follows Denji, a poor young man who hunts devils to pay off a huge debt to the yakuza, with his only companion Pochita, a small chainsaw devil. After an attack, the two merge and Denji gains the power to turn into Chainsaw Man. Makima then recruits him into Public Safety Special Division 4, a government team of devil hunters. Most of Part 1's cast revolves around that division: teammates such as Aki, Power, Kobeni, Himeno and Arai, the veteran Kishibe and, in the film, the fiends Beam and Galgali. The world also includes devils, born from human fears, and fiends, devils living in human corpses. This page covers 12 characters from season 1 and the Reze Arc film, described as they first appear, with no manga spoilers.
