This story continues in another manga as a side story. Here's the approximate chapter: http://www.mangago.me/read-manga/passage_from_servant_boy/th3/series/passage-from-servant-boy.html/1/82/
I kind of got lost somewhere with this story but I did enjoy the sex scenes!! I had no love feeling when they had sex but it was sexy!! I am glad everything went ok for Takashi and he is back a like sort of and he is friends with his brother again!! thx D
This story has a lot going on and I was enjoying it all till I say the last scan was done on 2/11/2011... That's too bad... I really wanted see how it ended. tt tt ("Passage from servant boy" you say, I'll check it out!)
For all the smut, it's a great story line behind it, and the smut is necessary to the demons plot. It gets rated low because of some hardcore smut, but it isn't just explicit all kinds of sex (shota-sort of, tentacles, demon exorcist using sex) there is actually a story that goes with it to make it into a really good, steamy and explicit manga that was hot. I wish there was more!
