This is a really solid little episode. Actually, I think the music (other than the openings and endings) was a little bit stronger than usual. It set the mood pretty well. The art was normal, but that means that it's great like always.
This episode is Makoto, Haru, Nagisa, Rei, Rin, Souske, Ai, and Momo battling each other in a water gun war. It's so cool? Let me explain. First of all, everyone is acting like a damn assassin, which is badass. And when they get "shot" they act like they've actually died, which is top tier hilarity. Makoto? He's super scary. Did you know that?
Also, you're gonna see some rare character interactions that barely happened or never happened in the main series. For example, Makoto and Souske. Can I just say, I finally understand why people ship them now? You'll see Momo and Nagisa, Rei and Ai, Rei and Souske, Haru and Momo, the list goes on. Of course, there will also be the classic Makoto-Haru interactions as well as the Rin-Souske, Haru-Rin, and Nagisa-Rei interactions. P.S. Kisumi is in this as well.
It isn't all just fun and games, though. Haru and Souske... well, I won't give it away, but this episode does actually advance their relationship and plot line together. It's mostly just a really fun and upbeat OVA, but the little bits of character development you get through Haru and Souske is really cool.
I took way too long to watch it, so please give it a go if you like the series. I think it's a good addition to the main story, anyway, so it's worth a shot.
