Black-Haired Demon Girl in a Sleek Swimsuit

character: kayoko_(blue_archive). In a medium cowboy shot against a simple grey background, kayoko_(blue_archive) from Blue Archive stands confidently, looking directly at the viewer with parted lips and red eyes. She has long, two-tone black and white hair in a ponytail with sidelocks and hair between her eyes, black demon horns, a grey halo above her head, a mole under her left eye, bare shoulders and arms, collarbone visible, wearing a black choker with earclip and piercing. She dons an alternate costume: glossy black highleg one-piece competition swimsuit with two-tone accents covering her navel, exposing groin area; her right hand rests on her thigh while her left arm is held across her chest, fingers gripping her bicep gently. Detailed fabric sheen on swimsuit clings to her form, intricate horn textures with subtle engravings, hair strands with individual highlights, piercing reflections, skin pores and subtle muscle definition, atmospheric depth with soft vignette edges.
