Despite his initial reluctance to take part in the competition, Ataru becomes interested in the game when he meets Lum. When the competition begins, Lum surprises everyone by flying away and Ataru finds himself unable to catch her. Before the last day of the competition, Ataru's girlfriend Shinobu Miyake encourages Ataru by pledging to marry him if he wins. On the final day of the competition, Ataru wins the game by stealing Lum's bikini top, which prevents her from protecting her horns in favor of protecting her modesty. In celebrating his victory, Ataru expresses his joy at being able to get married; however, Lum misinterprets this as a proposal from Ataru and accepts on live television. Despite the misunderstanding, Lum falls in love with Ataru and moves into his house.
