Kojirō Shinomiya, a Tōtsuki Culinary Academy graduate, commands SHINO's, his acclaimed French restaurant in Paris. His culinary journey earned him the historic distinction as the first Japanese recipient of the Pluspol award for advancing French cuisine. Rooted in a financially constrained Kyushu childhood, Shinomiya's passion ignited upon witnessing his mother's profound joy from a single French meal—an experience that crystallized his mission to recreate that happiness through his craft. At Tōtsuki, he dominated academically, surpassing even Fuyumi Mizuhara in her Italian specialty and ascending to the Elite Ten Council's first seat. Driven by his Pluspol ambition, he relocated to France post-graduation, dismissing concerns from friends like Hinako Inui, who challenged him to a farewell Shokugeki. France tested him fiercely: job rejections, colleague sabotage, and bouts of depression forged his stern demeanor. He implemented unyielding precision at SHINO's, demanding strict adherence to his methods. This rigidity surfaced during Tōtsuki's Training Camp, where he expelled students for minor deviations and deliberately supplied oxidizing ingredients to assess resilience. His confrontation with Sōma Yukihira and Megumi Tadokoro over her altered recipe escalated into an unofficial Shokugeki. Though victorious, Megumi's Rainbow Terrine pierced his emotional armor, vividly recalling his mother's warmth and rekindling his stifled passion. Shinomiya balances abrasive perfectionism with latent mentorship. Ruthlessly enforcing standards in his kitchen, he nonetheless guides those he deems worthy. This duality emerged when training Megumi for the Régiment de Cuisine: he galvanized her with a manga-inspired speech and taught her to weave her vegetable expertise into broader culinary themes. He respects peers like Gin Dōjima, whose counsel helped him navigate professional stagnation. He maintains firm professional boundaries yet cherishes select bonds. His dynamic with Hinako Inui thrives on sharp banter underpinned by mutual care, evident when he softened to comfort her during his France departure. He remained deliberately detached from conflicts like Azami Nakiri's Central regime, refusing overt involvement while quietly backing rebels. His culinary philosophy venerates precision and tradition, particularly in vegetable-centric French cuisine—mastery that bestowed the moniker "Légumes Magician." Initially intolerant of recipe deviations, he later embraced collaborative innovation post-growth. His career charts constant evolution: from conquering French adversity to mentoring successors while upholding exacting standards at SHINO's Tokyo.
