Well, considering no one has written a review of this, I might as well. The Love Live! School Idol Project OVA is a 15 minute descent into madness that was bundled with the sixth single of the anime's μ's idol group and aired on November 27, 2013. Why do I call it a descent into madness? Because the story of this OVA is complete nonsense. There's something about being in a dream, Maki's piano not working, tiny Maki scaring normal Maki for no real reason which is never brought up again, Ayase forgetting a textbook and then chasing after a shadow, it suddenly being nighttime,
Maki being a child for....some reason, and a fireworks show. Oh, and apparently the entire thing is a dream. Whose dream? I don't know! The show never tells us. I'm assuming it's Maki's, but it's never really explained. Maki as a child tells us that they are indeed inside of a dream, and that it is a "never-ending party", whatever that means. After that, Maki abruptly turns back into her usual teenage self via some sort of alien abduction or divine act of god, and then tells the other girls that she has always liked them.
That is roughly the first 10 minutes. The remaining 5 minutes is devoted to a musical number, a song called "Music S.T.A.R.T!!." If you liked the music in Love Live, it would probably be worth it to you to watch this OVA just for the song. I don't particularly enjoy Idol music, but the same quality of music and animation in the show is clearly present here (for better or worse), so if you're into that go ahead and give it a watch.
Also worth noting: I don't grade OVAs or specials; MAL forces you to pick an overall score to attach to your review. The score I gave this does not mean anything.
Look, this is something, that you'll watch if you're a fan of the show, but should basically steer away from in any other case. We have a story about Maki being in a dream with everyone. Subtle, I know. Anyway, she admits, that she loved everyone else, even from before they turned idols, big whoop.
This is a really materielistic OVA. What you'll get: a new music video, Maki in loli form and the characters interacting. You won't miss out on anything, if you just leave this one be, but it's not offensively bad, or anything. It's just a vaste of an OVA. But since
the series has an abundance of those, I'm not really heartbroken. This was the first I saw though, so that's kind of lame, but that is really the worst I can say about it.
In the future, please just release the music video and leave out all the rest.
