Dealing with the Devil

After completing "saving the master" you can actually get right back to the demon city and pay the boss a visit (even before meeting Parif). The good hellish boi might be willing to answer some questions if you help him stay awake by buying some (coffee) beans at the shop right next to his office.
Just go to the shop (marked with a “!”) and buy a bag of beans for him (they cost 8 bevocr, but he’ll give you 10, so don’t worry about not having money), then get back to his office. Since he is a naughty demon, he won’t actually listen to your questions, but you can keep some coffee beans, useful in cooking (you can always buy more down here if you have bevocr to spare).
