Imoshen

Hey, I'm looking for a fanfic... I think it's an AU. Sesshoumaru is under some kind of curse or spell (?), but he's human at day and a demon at night (or the other way around). Kagome is Naraku's slave and Sesshoumaru is rescuing her, now Naraku's hunting them - that all I remember. I don't know where I read it the first time. Could be mediaminer.org or even here on aaff.net It would be really great if someone knew about this story... I've been looking for so long and just can't find it.
