Shun Ibusaki is a second-year student at Tōtsuki Culinary Academy residing in the Polar Star Dormitory. He possesses a slender build, stands 180 cm tall, and has unkempt auburn hair that typically covers his slate-blue eyes. His reserved and taciturn nature often gives an aloof impression, though he harbors a competitive streak and privately sulks after defeats. Born on September 2, he dedicates himself exclusively to smoked cuisine, refining techniques with custom hand-prepared woodchips. He repurposed an empty dorm room into a smoking chamber, experimenting with ingredients like moshio salt, eggs, and apples, focusing on captivating aromatic intensity before taste.
As a first-year, he observed Sōma Yukihira's duel with Satoshi Isshiki and deduced Isshiki withheld his full ability. During the Tōtsuki Training Camp, he maintained composure through high-pressure assignments like the Egg Breakfast Buffet Challenge, passing alongside dormmates. In the Autumn Election Preliminaries Block A, his "Special Smoked Curry" featured multiple individually smoked components unified by applewood chips and smoked moshio salt, creating mellow sweetness. The overwhelming aroma earned praise for cohesion and 88 points. Tying for fourth initially, he ultimately ranked fifth after later presentations, eliminating him. Distraught over failing despite preparation, he isolated himself before dormmates consoled him.
During the Regiment de Cuisine, he supported the rebel faction opposing Central. He later attended the BLUE tournament as a spectator. Post-graduation, he remained active in culinary pursuits, occasionally collaborating with Polar Star alumni. Closest to Satoshi Isshiki among dorm residents, he recognizes nuances in Isshiki's cooking others overlook. Though frequently annoyed by peers' impulsiveness, he cares for their well-being and participates in group activities when persuaded. His physical strength contrasts his lean appearance, evidenced by effortlessly carrying heavy logs bulkier peers struggled to lift.
