Broke young man + chainsaw dog demon = Chainsaw Man!

Denji was a small-time devil hunter just trying to survive in a harsh world. After being killed on a job, he is revived by his pet devil Pochita and becomes something new and dangerous-Chainsaw Man!

A mysterious devil is demanding Denji's heart! But will the devil hunters from Division 4 agree to this deal to save themselves? Or will Denji have to do what Denji does best-turn into a chainsaw and carve up everything that gets in his way?!
