Hello, I've just started reading this manga online, Shuuen no Shiori, which I learned from a friend in DRRR! chat, it's pretty good (I haven't seen a crime/horror anime in a long time.) and it's from a Vocaloid song series just like MekakuCity Actors/Kagerou Days.

Original thread here: http://dollars-bbs.org/comics/res/1364756702.html although that one isn't very good either. Please delete this thread and include a decent description of what the manga is about.
