If you've ever wanted to know more about the Nekoma volleyball team, or want to watch a less volleyball-centric episode about the Karasuno team, these OVAs are for you. Be warned that watching the second OVA may spoil an episode or two of the second season for you.
Story - 8/10.
The first OVA is centred on the Nekoma team and their antics, in particular, Lev Haiba. It illustrates Lev and Kenma's (somewhat rocky) dynamic, and sets up a background for him as a character. For those of you who were unclear as to how Lev joined Nekoma's team, this episode will clear that up. I'd give
this OVA 9/10 by itself, however, I was less satisfied by the second OVA. One might consider the second OVA episode to be a retelling of one of the second season's early episodes. The plot covered everything from Kageyama and Hinata studying for exams to their arrival at the Fukurodani group training camp. If you've already seen these episodes of the second season, this is still worth a watch because it gives more depth to Saeko's descision to drive the two first-years to the camp (and Tanaka's attempts to convince her). As well, there's a funny scene involving the principal's wig...
Overall, I'd say the second OVA would be worth about 7/10.
Art - 7/10.
The OVA's art was slightly inferior to the anime's, however it still looks fine and was animated well. As long as you aren't expecting anything special, the art will be satisfactory.
Sound - 7/10.
There's not much to say about the sound other than that it was about average for Haikyuu!, nice but nothing special.
Character - 9/10.
Haikyuu's characters have always been one of its strongest points, and the OVAs, particularly the first one, give a lot of depth to previously unexplored characters. (Learning more about Kenma, Kuroo, Lev, and Yaku, among others, was the high point of my experience.)
Enjoyment - 8/10.
I love Haikyuu in general, so as I wait for the third season to be released, this was a fun watch.
Overall - 7.5/10
As far as OVAs go, this one was pretty good. I'd recommend it to any fan of Haikyuu!!.
