Basically if you've seen Mirai Nikki episodes 1-26(the original series) then this is basically episode 27 and goes on to show you what happens next. Its a very good end to a good show in my opinion, it is how ever only in subs from the time of me writing this. Never the less i'd highly recommend watching this if you watched the other 26 episodes.Overall: 4.5/5. Was a bit rushed, but hey what can you expect with only 1 OVA. Was perfectly content with this as the end. :)P.S. This should not be mistaken with the 8minute long OVA. The 8 minute long OVA is just a very vague look into episode 1 of the series, and isn't worth the time to watch because it is quite literally just bits of episode one cropped together to make a little summary of whats in store in the first episode.
