An illustration of a cute girl in a karate outfit with red gloves and a black belt, smiling and ready to fight. She has short hair tied back into two pigtails, wearing white pants and a top. Her expression is confident as she stands tall for the martial arts competition. Black background. Cartoon style. The art should capture her energetic pose and the vibrant colors typical of Japanese anime, with detailed attention to facial expressions, design, and lighting effects in the style of Japanese anime.
