Ever wonder just how convoluted and confusing Junji Ito releases are?Wonder no more, thanks to KoyanagiLulu.
Much of the mess comes from the fact that most of his smaller volumes are compiled and re-released as whole new volumes. The Junji Ito Kyoufu Collection, for instance. Which was then re-compiled for the English release, Museum of Horror.
Between 2011-2014 those covers you may not recognize are from a series that he only illustrated, Yuukoku no Rasputin (written by Takashi Nagasaku).
