This is supposed to be Kazuo Umezu, right?

I suppose you could consider this a hat-tip to Drifting Classroom.  And actually, that kind of puts Magical Girl Apocalypse into a different context for me; a lot of people are calling it a zombie outbreak series wearing more lace and ruffles, but its heart seems to be a lot closer to Umezu's senseless outbreaks of cruel surrealism.  The opening chapters do remind one inevitably of Highschool of the Dead (and both series have no idea how breasts work) or even Deadman Wonderland, but by the end of volume 1 we seem to be moving closer to a general breakdown of physics and sanity. We'll see how things develop...
