More mature anime style image. An image with a black background. a teenage girl, with long blue hair and red eyes, 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. 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 wings.. Behind if, seemed to have some kind of entity, a teenager with dark blue hair like hers and red eyes, a serious expression, behind her as if he was hugging her. A devilish mist around them.
