~EDITED REVIEW~ Nisekoi is a romantic comedy/harem that came out Winter 2014 and I sure miss that series. The Nisekoi OVA, I can say for sure, was a blast to watch and is enjoyable just like the show itself. But even as good as it was, it still has flaws. There are 3 episodes of the OVA, so let me talk about each one individually. Nisekoi OVA #1: The main focus of this OVA is the slight development to Onodera and Raku's love. (And since I am a big shipper of the OnoderaxRaku thing I really felt that the OVA was adorable) But don't worryChitoge fans, because they still manage to keep the comedic relationship between Raku and her. And believe me, it was totally worth it and hilarious.
For certainty, this OVA could be for everyone, but is more directed to the Onodera shippers. Due to it lacking some screen time for the other characters it might be disappointing for others. Nevertheless, I still recommend this OVA for people to watch if you already saw the series.

Nisekoi OVA #2
The first half of the OVA focuses on Marika Tachibana having a part time job at a family restaurant. You may be thinking, "Why does she need a job if she is already rich?" It is later explained in the episode, but the reveal is actually quite sweet and endearing. What I got from this first half was that is showed really great development for Marika.
The 2nd half managed to give screen time to all the characters of the show. It was New Year's Day and everyone comes to visit Raku's household. While they are at the house, all the girls got drunk and start being flirtatious with Raku (except Ruri). And by the end, we assume that all the girls did "something" with him. But instead are given an idea that is was all a dream. I felt this one was the weirdest out of all the parts of the OVA but still gave us quite a few laughs.

Nisekoi OVA #3
OVA #3 is a hot spring episode with all the the characters shown. However, all the girls in the series were just there for fanservice. So if you are into that type of stuff, then this episode could be for you. As a person who doesn't like fanservice I was quite disappointed.
This OVA does have a good thing to it though! We were introduced to new characters that is in Nisekoi season 2, so that's a plus.
In all, this episode is the one I liked the least. If you like the ecchi type of atmosphere to a harem anime, then you may end up liking this a lot.

Anyways, try checking it out! The Nisekoi OVA's are something you should at least watch watch if you were a fan of the series beforehand. Though some episodes may not be good as others, they still are enjoyable at the least. If you haven't watched Nisekoi, then I recommend that you should watch it too. Hope you give it a watch and have fun watching it.
