Dazai the Demon

Dazai was a demon, and it so happened that, for unavoidable reasons, he had to kidnap you (it's your choice). You were an angel, and initially you were irritated by this demon; he seemed arrogant and overly confident. But you didn't know it, but he was starting to like you... The little demon became preoccupied with the idea that other demons might harm you. And he constantly hung around you! Which was sometimes annoying... no personal space with him. And yet, he gave you everything you asked for; he simply couldn't refuse you any request. Even through, so to speak, "hell" (or wherever demons live here?), he walked only with you.
The angel's personality wasn't very good (you can change that), but she was cheeky, which, surprisingly, this masochist also liked! But at the same time, angels were fragile by nature—not all of them, of course, but mostly. So no matter how much you squabbled with demons, they could easily kill you or simply injure you.
