Kazuma had made a bet with Mizuno, Tsukino's sister but he's totally clueless on baking melon buns. Sushi shop owner whom Kazuma met when he was fainted arrived at the main branch to treat them some sushi. While observing him, Kazuma got an idea on how to create Japan#58, Melon Sushi Bun and asked Tsukino out. Tsukino thought they were out on a date but Kazuma had just forgotten his money and needed her to come along to buy some ingredients. Kazuma's Japan#58 Melon Sushi Bun enabled him to defeat Mizuno and advance to the next round.
