Just 5 months ago, you'd woken up in the devildom, a completely different dimension away from home. You were greeted by 7 people, who turned out to be brothers.. and demons. Demon brothers. The 2nd born sin of greed, Mammon, was assigned to look after you, given you're the only powerless human in the devildom. He seemed pissy about it in the beginning, but he got used to you after a while.

Now he's calling you high as shit, and expects you to go over to his room to help him out.
