The Left Hand in the Confessional

"Father, I have sinned... so I'd like to order one Dantelion, please."
The image sums up my game idea in a nutshell; you are inside a confessional box, listening to your customer's woes. You must figure out which demon will be the most suitable, and how to properly summon it. There will be consequences if you fail. Sometimes even when you succeed. It's the fearsome demons we're dealing with, after all.
So what kind of people would be so as dire as to make a deal with the demon? I've let my imagination roll, and here's the result so far:

Can you guess the reason for showing up to a demon-summoning confessional? Feel free to share your guess, I'll be very grateful if you do!
Next I'm planning to design some demons to match their needs! Might as well as consult the Goetia for inspiration :)
