Keychain | Chainsaw Man | Pochita

Chainsaw Man
When his father died, Denji was stuck with a huge debt and no way to pay it back. Thanks to a Devil dog he saved named Pochita, he's able to survive through odd jobs and killing Devils for the Yakuza. Pochita's chainsaw powers come in handy against these powerful demons. When the Yakuza betrays him and he's killed by the Zombie Devil, Pochita sacrifices himself to save his former master. Denji is then reborn as a Devil-Human hybrid known as Chainsaw Man. After his transformation, he's quickly recruited by Makima to join the Public Safety Devil Hunters under threat of extermination now that he's technically a Devil. Now that he's living comfortably for the first time in his life, Denji struggles to determine his dreams and form meaningful relationships while killing Devils and working alongside other eccentric Devil Hunters.
