A soft retro anime illustration, muted faded palette, gentle cel shading, delicate linework, warm nostalgic light., a sun-kissed young woman with athletic build and a determined yet dreamy expression, clad in a vibrant, retro-inspired athletic swimsuit, leaps mid-air to spike a volleyball. she is surrounded by an ethereal swarm of iridescent butterflies, their wings catching the soft, golden hour light that bathes the serene beach landscape in a hazy, dreamlike glow. the scene is rendered in the 'flux + retro anime flux - style', evoking a sense of nostalgic beauty and dynamic motion with its fluid lines and soft, pastel color palette.
