It's here, the epic conclusion of Umezz Kazuo's classic horror manga.  This is the third of three 700+ page volumes collecting the entirety of the series.  Originally published in Japan during the early 1970s, it was belatedly issued in the US between 2006 and 2008, in a series of 11 softcover editions, all of which have long been out of print and difficult to find.  Now, it is at last being re-issued, in a series of three massive hardcover "perfect editions" from Viz.
