Oh yeah! I watched a LP of it last year and spent a lot of time enjoying it. I enjoyed the manga scanslations even more for how the mangaka combined routes and added characterization. The mangaka also added as much Ayumi/Yoshiki as was humanly possible, so even though it's currently unfinished, I'd say it's worth a read just for the new scenes. The manga in question is Corpse Party: Blood Covered. I wouldn't advise you go into Corpse Party Musume. I went for "so bad it's good" and found it only "so bad it's horrible."

However, I forgot to copy my meta over here, and I haven't finished the few fics I was working on. It was just short manga stuff.

I like Naomi/Seiko as well, but that pair is a little too painful given how many times I've had to see Seiko die by now.

Oh yeah, I haven't finished anything but the translations of Blood Drive. I still have to watch Book of Shadows, actually. I was having a hard time finding a decent LP.
