I enjoyed watching the series for Kore wa Zombie Desu ka, so why not watch the OVA?
In the end, I liked this OVA. It had its funny moments.
There are 3 parts in this episode and I enjoyed them all. There wasn't too much ecchi during the first two parts. However in the last part of this episode, it was filled with ecchi. Personally, I don't mind the ecchi.
The art for this anime was good, it was consistent.
The one thing that I found awkward was the voicing for Hellscythe. Overall, this episode was amusing.
After watching both the series and the OVA, I'm looking forward to the second season.
Overall, I give this anime an 8.
