This is a 1.2x speed version of the opening from Alnoah.Zero.
I've found myself listening to anime openings and endings 1.2x faster on my phone and felt like I should upload some of my favourites. As far as I'm aware this isn't Nightcore but I'm not particularly sure, so I'll just refer to it as 1.2x speed.
