FALLEN MOON (Daten no Tsuki), by Toui Hasumi. First published in 2004 and first published in North America in 2008.
PLOT:
In this collection of stories, a man cast out of his personal Eden finds himself trapped in the lavish household of a fallen angel, where he is held captive just as much by his captor's will as he is by the walls. In another world, an artist and his patron turn out to have a far longer and far more divine history than at first glance. Finally, a bounty hunter and his partner face off against demons, only to undergo transformations and revelations of their own.
