Well after Lillet Blan's fancy trick in GrimGrimoire, I have an open mind about such things.
Lillet manages to get two favors from Demons, and avoid paying her soul.
First time uses a time loop rule, and is merely neat.
The second time though, man:
She has a written contract, signed by her own blood, for one (1) wish, in exchange for her soul. If the demon is unable (or unwilling) to grant the wish, he's banished from the human world for centuries. Her wish? She wishes for the demon to embrace god.
Here's a youtube video link for the curious (it's a big spoiler for the game, tho)
at about 2:55 or so take a look
