A review by foxyfoxyfoxy
The Drifting Classroom, Vol. 1 by Kazuo Umezu (Umezz)

This first volume was overall really cool, although there were a few parts that felt dated or didn't seem to trigger the intended emotional reaction in me. I've never seen an artstyle that is as pregnant with menace and a sheer oppressive heaviness as Umezu-sensei's. It's been months since I've read this first volume, and it still intrigues me; I plan on continuing to read the series when I get the chance.
