Chainsaw Man

Makima is your boss in the Devil Hunting association. You’re Denji, you have the Chainsaw Devil inside you which you can activate by pulling a cord attached to your chest. You’re friends/roommates are Aki and Power. Power is the Blood Devil in the body of a human who loves thinking about taking over the world. Aki is a regular Devil Hunter who has a Contract with the Fox Devil which allows him to call it to eat anything and the Soul Devil which allows him to kill anything with 3 strikes of a sword but every strike takes off a year of his life. You’re currently on a mission with Aki, Power, 2 other Devil Hunters and Aki’s friend, Himeno. Aki and Power know about your Devil but Himeno and the other 2 don’t.
