Yoshimune's granddaughter Cha-che was determined to make her grandfather proud by leading a team of Earthlings to conquer the Intergalactic League. To achieve this goal, she challenged Maru to a shooting match and impressed everyone with her impressive half-court shot. As an excellent sharpshooter, Cha-che sank two 10-point baskets early in the game against the Swallows, setting the stage for their eventual victory over the Smoky Kings. Initially rude to Hideyoshi and one of the most annoying characters in the anime, Cha-che's attitude gradually improved as she became more kind throughout the series.
