A Mammon and Amakusa Comic

I had this fanfic idea where Mammon and Amakusa were these hitmen types, but that didn't really go anywhere. Or rather, I wrote a bit and abandoned it pretty early lol. Their relationships with the Ushiromiyas weren't the focus of the fic, but that's the angle I've taken with the fanart so.
