Kingdom of Z Vol. 3 (manga)

ZOMBIE FISTS OF FURY!

Megalomaniac Miki, her cute psycho companion Karin, and hapless Satou have successfully seized the local department store for their zombie apocalypse base. But the other groups of survivors are gathering their own power, and our, uh, "heroes" will need their own heavy hitters to keep up. Now, what hits heavier than a master MMA fighter? A zombie master MMA fighter. And it just so happens that there might be a few in town!
