Chainsaw man: Chained Down.

"Y/n you won't be able to give your consent but I'm not letting you die"

This world was filled with blood in death, more people died from demon attacks the from natural causes.

However the world developed a fighting force to this and humans part of public safety hunt down demons for money.

You are the son of two professional demon hunters and you aspired to be just like them ever since you were a child.

One day your found a demon injured and saved it's life like a certain dog like boy.

Years later this same demon saved your life like you did for it.

I know shitty summary but I ask to give the book a chance.

Also I don't own chainsaw man or any of the images used.
