At the Shokugeki, Ikumi wows the audience with her A5 grade beef, while Soma is mocked for using discount supermarket beef. Ikumi completes her A5 Japanese Beef Roti Don first, and the judges are extremely impressed with the taste and quality of the meat. Soma then presents his Chaliapin Steak Don, which the judges initially refuse to taste. Once they do, they are unable to stop eating, resulting in a unanimous win for Soma. Soma points out that Ikumi misunderstood the concept of donburi by placing too much emphasis on the beef and not on the dish as a whole, as the judges were too full from eating the beef to finish her rich garlic rice. With Soma's victory, Ikumi has her personal kitchen taken away from her by Erina. She joins Don RS and is immediately outraged and embarrassed to learn Soma did not join the club with her, as he had only visited Don RS to research donburi recipes to add to his restaurant's menu.
