/jp/ - Otaku Culture

Hey /jp/. I was in Japan from May 21-30 of this year. On the evening of the 29, I was relaxing in my room in the Hotel Nikko Narita watching TV. The channel I had it on was playing First Gundam before moving into an episode of Iron-Blooded Orphans. Anyway, one of the commercials that came on really caught my eye. As I understand very few Japanese words and can't read a lick of it, I have no idea what the commercial was about or for. It involved some brown-skinned mecha musume girl with robot wings either as arms or on her back, and there was some sort of dubstep music playing. Each time the music swelled, some sort of pulsation emanated from her, and she struggled against this apparatus that had her restrained. Eventually, there was a big swell, she broke free, and the music started doing other dubsteppy stuff. Anyway, some words appeared on-screen, and there was a four-letter English word I missed because it only popped up for a moment. There was a narrator saying some stuff, too. Do any of y'all have any idea what this commercial was?
