Shoji Sato, a Totsuki Culinary Academy student and Polar Star Dormitory resident, sports dirty blond hair styled in a semi-mohawk with darker edges, his unbuttoned uniform and missing tie underscoring a casually rebellious image. Despite his rough exterior, he vigilantly defends dormmates against criticism and champions their efforts in competitions, balancing abrasive banter with unwavering loyalty—particularly toward Daigo Aoki, his frequent sparring partner and inseparable companion. Admitted to Polar Star after clearing Fumio Daimido’s entrance test, he engages actively in communal life, often gathering in Zenji Marui’s room. Though overlooked for the Autumn Elections, his practical culinary skills—exemplified by straightforward dishes like fried shrimp snacks—secure his place at Totsuki, prioritizing functionality over flair. His name, combining the kanji for “shining” and “two,” aligns with his narrative peculiarity: debuting in Chapter 7 of the manga but remaining unnamed until Volume 9, sharing with Daigo the record for delayed identity revelation. Their absence during a pivotal dormitory incident in Episode 19 underscores their peripheral yet enduring presence, as Shoji operates primarily in the background—bolstering group cohesion through subtle support rather than central plot involvement.
