Well, for a moment there I thought the OVA will be just another fan service.
Turns out the OVA of Witch Craft Works itself, in my opinion, generate more excitement for me than the actual series itself. It is very light-hearted and to be frank, the comedy is very refreshing.
Bringing the bro-con topic of the main character's sister and WWE-ish featuring bear and penguin, the OVA is just an extension to the main series.
The art and the sound are very much the same with the usual series. The character however, stole the spotlight in this OVA.
I have to say that the OVA is much more enjoyable and comedic compared to the main series.
For overall resultt, this is one OVA that is good, if not, better than the main series in term of enjoyment.
