More mature anime style image. An image with a black background and some purple details. a teenage girl, with long light blue hair and red eyes that gave off a kind of glow, wore a white dress shirt rolled up to the elbows and a vest, black pants and black boots. Small black horns came out of her hair, his skin had a gray tint. A human image, but still diabolical. A dark aura around him ready to kill at any moment along with his serious expression. He used a katana that emanated a dark purple glow around him.. There was a strange glow behind him that gave the shape of purple wings..
