The story was good, but trying to fit so much into one episode was just waaay too much. At the beginning, one second you would be watching a slice of life kinda thing, and then the next second it would just go to two girls in another world fighting each other. Extremely confusing much? At the end, you figure out how they are related, but a big question still remains: who the hell is BRS? You don't get any detail on that...zero. *spoiler* And if that isn't good enough, suddenly Yomi goes missing, and then we find out that she somehow got to the other world and was beating up BRS because of what was happening in this world and blah blah blah-WTF?
I honestly don't know what to think of the animation. At some points, I think the animation looks competely awesome, but next thing you know, it's just plain crappy. That's all I have to say on that matter.
The voice acting was good, then again, I'm not good at judging Japanese voice acting, so excuse me if it's actually terrible. xD Anyway, is it just me, or did they not use the BRS song sung by Miku, for the BRS anime? Seriously? Can't they fit two and two together, or are they really that retarded? If you're gonna make an anime about it, shouldn't they at least use the fricking song? Honestly...
Characters...for all I know, there's "School Girl 1", "School Girl 2", and "School Girl 3". I'm really bad at remembering character names, but because it was just one episode, I did not get a lot of time to remember them. I knew close to nothing about all of them, other than the fact School Girl 1 likes to go to a place overlooking her town, School Girl 2 moves with her family a lot, and School Girl 3 is an annoying little brat that School Girl 2 is jealous of. Amazing, right? They're the characters that make me want to sarcastically say, "How original".
The story originated from a song, so I can't say it's good point is being original. Confusing, unoriginal, poor animation, no character developement...do I really need to go on? Overall, it's garbage, crap, not even good enough to be flushed down a public toilet. Don't watch it. It's a waste of time. :T It you want a story watch the MV for BRS. That's way more interesting than this shit.
