Rentarō Kusunoki is a 91st Tōtsuki Generation student and a former member of Central. Rentarō is highly confident in his cooking skills and takes pride in the fact that he was chosen to be a member of Central. His confidence was further shown when he personally informed a Research Society head about the purge so that he could take the chance to crush them. He is also easily irritated when underclassmen disrespect him. While he is quick to temper, he calms down quickly while cooking, channeling his emotions into his food. Rentarō enrolled into Tōtsuki Culinary Academy as part of the 91st Generation. As Rentarō made it to his second year, he successfully completed the Tōtsuki Friendship and Rapport Training Camp and Stagiaire events in his first year.
