I have first four volumes or so, as I'm not sure whether v4 is finished, and might not find out as the scans of v4 are so poor I don't want to read them. In any case it seems to me nobody is scanlating it anymore, except for Tokyopop since they licensed it. But from what I can see they have only released volume 1 so far, possibly volume 2.

After three volumes this looked like a pretty sad manga. 70% (just a number from my hat) of material has been cut, and I have no idea whatsoever how much sense it would make if I hadn't played the game and thus wouldn't already know everything. But you can imagine it wouldn't have nearly as big an impact... It's kind of annoying to read. I'd never buy it, as much as I love FSN. Or precisely because of that.
