This is cosplay of an Adepta Sororitas, a Sister of Battle from the Warhammer 40,000 universe. If I had to explain that to you, you probably don't understand why my panties are soaked.

When I was younger I used to watch a cartoon called Robotech, in the opening credits these mile-long alien space ships would be getting cored by space lasers and would explode from the inside, bursting like overripe fruit, and splattering all over the solar system. I always thought it was just crazy anime science fiction, until I saw this. At about 5:13, you see ballistic gelatin being exploded by rifle rounds, and I saw a childhood of badly dubbed VHS tapes from in that moment.
Specifically, 1:16 here. Can Japanese animators see at a million frames a second?
