This short, from my understanding, comes with one of the Naruto video games. As a short, it isn't the greatest, but as bonus content on a video game, it's kind of cool. It helps set up the situation behind the game.
However, because of this short being set up for a game, it doesn't come to a real conclusion. I kind of want to play the game, just so I can get a real conclusion, but I don't have the time or money to get a new video game at the moment. So, I guess in that sense, the short does well in making you want to play the game.
The animation was on par with the rest of the series, as was the music, and it was fun seeing a lot of clashes between various ninjas. I'm not sure how much I believe an event like this would actually happen, but it was a nice explanation for a fighting game.
I guess what I'm really saying was that this OVA wasn't the greatest when it comes to story, but it holds up a little better than it normally would because of the game its attached to.
