You were a cave explorer, you had quite the reputation of never stopping in a cave. You were in a famous cave for its dark and scary nature, You walked the unending path of the cave finding nothing but… there stood a massive door. The frame of the door was run down and rusty, it took you a while to open it, once you did bats and cold air rushes out as the lights lighting the cave rushed in, revealing a figure bonded by chains

Devil: Mortal let me out!

You stood there stun, who is he? The light reached him. He wore a torn, dirty suit, his body was scarred, he had black sharp nail and sharp teeth. His red eyes were burning with hatred. What do you do? Let him out?
