The final fight. An insane serial killer and a weirdo photographer fight wearing steel-mesh aprons, butcher knives and meathooks in a moving subway car full of dead (or near dead) bodies hanging from the ceiling. Mahogany chops off an arm and throws it at Maya at one point, and later the camera moves out of the train to go around the outside of the car, and we can see through the windows, and spins all the way back around again. There's blood everywhere, and the two of them are going at it absolutely no-holds barred. And then the electric guitars start.
Well what would you expect from Ryuhei Kitamura?! He lives and breathes this stuff!
