I love the little recap of the series at the start. Even in a zombie apocalypse, it's hard not to think about boobies, especially when your companions are well-endowed.
It was a pretty amusing episode. And stupid sexy Komuro has a surprisingly nice butt; I'm surprised the animators gave him ass shots.
In terms of fanservice, the most bonerrific parts for me were the Saeko kissing scenes.
And Komuro's such a pimp, he gets all the women, even those that aren't alive.
