Let's Make a Harem in a Zombie World! GN VOL #2

Nerdy Kosaka Koutaro finds that he has a strange power--sex with him can keep a girl from becoming a full zombie! Sounds like an all-girls school would be a good place to hide out, but soon he incurs the wrath of King, a tyrant who rules the school with an iron fist loaded gun! With no other choice, Koutaro ventures into the outside world where he'll encounter plenty of danger...and a pampered young lady who’s wildly curious about indecent things...before his return to feed the starving co-eds!
