Black and white illustration of the anime character Riko from "Sabilaida" in an elegant pose, surrounded by swirling black shapes with blue highlights, creating a dynamic contrast that emphasizes her mysterious aura. The background is minimalistic to highlight her figure, with subtle details like flowing hair or detailed elements. Use a vector art style for sharp lines and clear edges. Ensure there's no text on any part of the design. No words, only colors. --ar 23:32 --niji 6
