Kore wa Zombie Desu ka? Review

This one is a bit outside of my general genre preference.  I tend to overlook most moe/fanservice/harem type animes that filter through each season, but for some reason or another I found myself watching the first episode one day.  The premise is Aikawa Ayumu is killed by a serial killer and then revived by the necromancer Eucliwood Hellscythe.  Ayumu decides to become her protector so she starts living with him.  Shortly thereafter two more girls move in to complete the harem.  One of them is a vampire ninja and the other is a self proclaimed genius mahou shoujo.
