Title: A Soul's Worth
Pairing: Sebastian Michaelis x Roy Mustang, hints of one-sided RoyxMaes
Rating: R for some violence and sex (and possibly sexy violence ;-)
Timeline: Diverges from episode 25 of FMA, first anime. May also feature some vague references to events in Kuroshitsuji.
Summary: A cunning demon offers to help Roy track down the ones responsible for the death of a friend. And all it will cost him is his soul.
“Perhaps I can help you with that.”
