Gin Dojima, a pivotal alumnus of Tōtsuki Culinary Academy’s 69th generation, shaped the institution’s history during his tenure at Polar Star Dormitory. Alongside Jōichirō Yukihira—then Jōichirō Saiba—he spearheaded a partnership that dominated Shokugeki battles, securing both Polar Star’s financial independence and their era’s legacy as the "Golden Era." Gin claimed the Elite Ten Council’s 1st seat in his final year, yet openly acknowledged Jōichirō’s superior culinary prowess despite the latter holding the 2nd seat. When Jōichirō abruptly left Tōtsuki, Gin graduated with the academy’s highest-recorded academic score, rejecting lucrative careers to join Tōtsuki Resort. Motivated by a resolve to mentor future chefs and avert struggles like his friend’s, he rose to General Head Chef and Board of Directors member, directing culinary operations and intensive student training camps. Gin enforces a leadership philosophy rooted in strict professionalism, demanding accountability as if students were employees. He prioritizes action over words, exemplified by confronting alumnus Kojirō Shinomiya over complacency during Megumi Tadokoro’s expulsion crisis. His insight identifies hidden potential, such as Megumi’s talent for hospitality-infused cuisine, which he urges her to refine. Muscular and sharp-eyed, Gin’s imposing presence features a signature silver earring, maintained alongside a disciplined fitness regimen during daily bathhouse routines. He balances authority with tradition, evidenced by annual Obon and Shōgatsu cards sent to Polar Star’s dorm mother, Fumio Daimidō. During Azami Nakiri’s authoritarian regime, Gin mentors rebels like Sōma Yukihira and Megumi in the Régiment de Cuisine, haunted by past failure to curb Azami’s ideological shift—a fellow Polar Star alumnus. In the BLUE tournament, he collaborates with Jōichirō to train Sōma’s group while warning Erina Nakiri of Asahi Saiba’s threat. Gin’s dynamic with Jōichirō intertwines mutual respect with lingering tension over their estrangement. Their reunion channels years of frustration into pride for Sōma’s growth, reflecting Gin’s role as a bridge between Tōtsuki’s legacy and its future. His unwavering dedication to nurturing talent cements his stewardship of the academy’s culinary ethos.
