A vibrant and cute anime style illustration of a futuristic, utopian school campus. In the foreground, three cheerful high school girls with colorful hair (brown twintails, purple ponytail, and long light blue hair) are wearing stylized modern gym uniforms consisting of comfortable dark blue zip-up track jackets and classic retro-style navy blue gym bloomers (buruma). They are interacting with sleek holographic smart devices floating above their wrists and sitting on a futuristic glowing bench. The background features a sprawling, clean sci-fi school yard filled with lush green vertical gardens, advanced eco-friendly buildings with curved architecture, solar panels, a glass dome labeled 'CYBERNETIC ATHLETICS HUB', and a monorail passing by under a bright blue sunny sky. Bright, clean lighting, optimistic and harmonious atmosphere, highly detailed anime aesthetic
