Among the many research societies across Tōtsuki, one was devoted to researching Donburi, the Don RS. Unfortunately, after her latest victory over the Chan RS in a Shokugeki, the Don RS became the next target for Erina Nakiri's kitchen expansion project. The current president, Kanichi Konishi, did his best to inspire the club members to stand up and fight against the new threat to the club, but most abandoned it when the news arrived at the club of the leader of the attack. Alone, Kanichi would have to face this new threat by himself... or so it would have been if not for an unexpected visitor to the club.
During the Shokugeki, Ikumi used A5 meat, seemingly thinking that she has the upper hand due to her having higher quality meat. On the other hand, Sōma used cheap meat, much to the audience's chagrin. Regardless, he did not care about the outlook of the audience and cooked his dish anyway.
Ikumi was the first to finish and she presented her dish to the judges. With certainty, the Judges were greatly impressed by the A5 meat that was presented to them and noted that the food was good, for the aformentioned reasons. However, they did not see that Sōma had something up his sleeve. Despite using cheap meat, he greatly compensated by making sure that the other ingredients (e.g. rice, sauce) complimented the dish's quality. Much to the surprise of the audience, one of the Judges asked for a second serving.
Judges' Votes Edit
As a result of Sōma's dish being so well done despite him using cheap meat, the Judges voted unanimously, 3-0 in favor of Yukihira. For a transfer student to win a Shokugeki against a talented chef, the audience was greatly shocked upon this decision.
Due to the failure of Ikumi to defeat Yukihira, Erina asked that Ikumi's kitchen be given back to her. Furthermore, as with the Stipulations of Yukihira's victory, Don RS can no longer be targeted by Erina as well as Ikumi being required to join Don RS. Moreover, Yukihira asked Ikumi to try out his dish, and she was in awe with how good it tasted.
