Jōichirō Yukihira (幸平 城一郎 Yukihira Jōichirō) is the father of Sōma Yukihira. Formerly known as Jōichirō Saiba (才波 城一郎 Saiba Jōichirō) he was a 69th Tōtsuki Generation student, a former resident of the Polar Star Dormitory, and a previous 2nd seat of the Elite Ten Council. For unknown reasons he did not graduate from Tōtsuki Culinary Academy, but Jōichirō still became a world famous chef before settling down in Sumiredōri Shopping District to open his own restaurant, Restaurant Yukihira. And he didn't graduate... Although he is like one of the badass characters, you can't blame him... I personally think, it has something to do with the Stagiaire Arc; it occurs as soon as the Autumn Election Final ends. Stagiare is an event where students are sent to the former alumni or professional chefs' restaurants all around the world, if they don't meet the requirement they face expulsion. For example when Soma had his second Stagiaire at Kojirō Shinomiya's restaurant at France he developed some skills as well and faced some troubles too. But some students end up working for the restaurant, we learn it from chapter 105 when Jun explains the basic of Stagiare. And could it possibly be connected to it? Did Joichiro do the same and worked for a top restaurant, although he was second seat back then. [Scene from Shokugeki no Souma Chapter 105] Give me some of your ideas as well?
