The killer of Akame

Red, viscous orbs float across a brick street under a purple night sky, then the scene cuts to a monstrous, wolf-like creature with glowing red eyes and sharp teeth, its mouth open in a snarl as it looms over a small, white-haired girl in a dark, urban environment. The creature's head moves slightly as the girl lies on the ground, a large weapon beside her, while the creature's body remains mostly still.
