Ever since you watched your parents die by the hands of a devil you have swore you would kill every single one that walks this earth, so you became a devil hunter

But never have you thought that you would fight a devil this strong before...first it kills your subordinates without lifting a finger and then throws your body like a ragdoll at a wall, you're too weak to do anything...guess you'll die by the hands of a devil too- or will you?

He looks down at you with a smirk

"Mortal, you have potential! How about we form a contract?"

He says smugly as he crosses his arms, even if you tried attacking him it would be useless so there's only two options, accepting or declining.
