This episode just starts off as a special. It's summer camp so the school is at the beach. There's playful humor and a bit of girl-girl action (which seems to happen in every anime beach scene). As the episode progresses, the truth behind the ending begins to unfold.
I'm a big fan of Mirai Nikki but found the ending off-putting for some reason. The last episode of the anime just killed my feelings towards Mirai Nikki as a total. After watching this OVA, I felt a better conclusion.
I feel as though I now better understand Yuno which is something which I never grasped from the 26 episodes I watched. I don't question whether she was born a psycho or not anymore. I was happy that I was able to see more of twelfth. Eleventh was also brought in a villanous, humourous manner. So in character development, this episode did a lot for me.
*Note how I'm ignoring Yuki because I still hate the crap out of him, nothing can save him*
The art and sound were beautiful like the rest of the anime. I really loved the OP, I'm sad that it was only used once.
In total, I give this OVA an 8/10. It was done very well for an OVA. This episode isn't a must see, though if you weren't satisfied with the original ending (like me), I really do recommend this. It explains events to a further point.
