The only reason why nobody want to write a review about this OVA is either because they watched the 12-episodes series first, which came out a year before, without watching this OVA at all; or because they watched the 12-episodes series first and then watch the OVA and held a grudge upon it afterwards because of the very disappointing previous series, which made this OVA appear to be mocking the audiences' expectation; or because they watched neither of both, despite the fact that this particular one here is actually a good comedy anime out there even though this is just an OVA.
previous Kill Me Baby was pretty much not quitely appealing to audiences because of its unfittingly slow-paced-old-gags travesty of comedy, this OVA, in a way, made the most of it. Although the rest of this anime (OST, characters, plotless theme) is just the same as the old one, the faster pace, the various witticism with its more aggressive (often violent) approach and the stronger-ly unique characterization, somehow made me laugh more often compared to when I was watching the first series. Because it was aired after the first Kill Me Baby TV series, however, this potential OVA would make you feel like you're watching J.C.Staff's product of redemption, or aplology, or mockery, or carelessness out of sympathy over the series. Name it whatever you want.
It doesn't matter how bad something in the past could be, nevertheless. If you'd like to see what potentially would be the best comedy anime out there (if you don't mind with 'chibi' characters and plotless random happenings), this particular OVA would help you.
