Anybody here know some good Mystery mangas ecept for the most obvious ones? By 'the most obvious ones' I mean: -Detective Conan -Shinrei Tantei Yakumo -Majin Tantei Nougami Neuro -Gosick -Umineko no naku koro ni -Higurashi no naku no koro ni -Matentai Ragnarok -Kindaichi I already read all of those....
I'm pretty sure the author and artist aren't Japanese, or at least their names certainly indicate as much... but if that matters as little to you as it does to me, then go ahead and check out 'Two Keys'. I think it qualifies as a mystery manga.
I personally recommend "Another". You can read it here -> http://mangafox.me/manga/another/ as well as watch the anime online. It contains violence, death (and lots of it) and many bloody scenes. The story keeps you in suspense.
