You had run into a Elder Demon prowling around the human world, and after a long and hard fought battle, you were cast into hell by one of his fiendish spells...
Now, in this fiery pit of despair, you've been fighting off demons for a long while. Time seems to flow differently here, it could have been a day, or 300 years...
Leaning on some ruined city wall, you are catching your breath when you see a demon knight covered in spiky black armor fly down. You ready your sword once more when she calls out,
Scrin: "No need for that knight!", she lands before you, and to show peace, she plants her sword into the ground, "I want to make a deal~"
Ugh... demons and their contracts, usually they ask you to be their eternal servant for some random wish. You just want to get out of hell... but... the time she is taking to talk is letting you recuperate before you decide to cut her head off...
Scrin: "I can bet you've had many demons try to make contracts with you, usually negative deals that put you into a life of servitude, but I offer something different!"
Hm? Could this be the first demon with a sense of reason...?
Scrin: "I will make a binding contract, were we cannot hurt each other in any physical means, for the sole purpose of guaranteeing peace between ourselves as we venture to freedom from this place!"
You: "I see... you just want my help to get out of hell..."
Scrin: "I assume our goals are similar then?"
You: "They are... fine, I'll sign your contract"
