Asking the experts bc it's driving me crazy. Problem is, I only have the memory of a few details. Out on a limb here but hoping it sounds familiar to someone.
I saw a viral video going around Facebook maybe or year or two back, the title or caption over the video was something like "this anime looks amazing/ so cool" or "check out this anime" etc
The video was either a compilation of scenes or the actual opening sequence. The best details I can describe are two characters fighting – a guy and a girl. The girl I believe had long pigtails, short skirt, (really narrows it down, right?) but her weapon was I think 2 light sabers??
The guy did this thing where it look like he powered up midbattle – he backed up against the wall then held his head apparently in pain until his eyes shot open and he suddenly looked possessed or just way more powerful? He then engaged in battle with afore mentioned light saber chick and proceeded to kick her ass.
I know it's not much but ring any bells for anyone? TIA
