A slender, muscular high school boy with short red hair stands in the center of a futuristic classroom during a lesson. He wears a revealing, futuristic school uniform consisting of a cropped, sleeveless white top with blue accents that exposes his midriff and defined abdominal muscles, paired with tight black shorts and thigh-high socks. His expression is serious and focused as he looks slightly to the side. The background features sleek, metallic desks with holographic interfaces, glowing blue and white neon lights, and large windows showing a high-tech cityscape. The lighting is cool and artificial, casting sharp shadows and highlighting the textures of the uniform and the boy's physique. The atmosphere is sterile and advanced, with a shallow depth of field blurring the background details to emphasize the character.
