ohh.. have you tried Requiem from the Darkness. It is a story in old Japan, but the story is about a boy learning to be a reporter, story writer and detective. On his travel, he meets 4 demons, that actuall help him. And it is his travel to find reasons for the actions of the 4 demons, and their past history.
hope this helps
