It's a fake. The beginning of the song doesn't match the intro which is featured in the sample of the song on Jrock Revolution's website. o.o
Edit- I listened to more of it and some part do sound like the parts of the song I've heard in other trailers, samples, etc. But I have a feeling that either:
1. Something went wrong when the song was uploaded, as it sounds like the song plays up to a certain point before you hear it start over again and play with the first start. If that makes any sense. o.o
2. The person took the samples, mashed them together, and made weird distorty effects so nobody would notice that she did this. XD
