Shoji Sato attends Totsuki Culinary Institute as a Polar Star Dormitory resident. His appearance features dirty blond hair styled in a semi-mohawk with darker edges, typically layered over sweaters or long-sleeved shirts beneath an unbuttoned Totsuki uniform lacking a tie, reinforcing his tough demeanor. He dons standard chef's attire during cooking. Despite his rough exterior, Shoji displays fierce loyalty toward fellow Polar Star residents, defending them against insults and supporting them in competitions. He frequently engages in heated arguments or physical clashes with close associate Daigo Aoki, yet the pair remain nearly inseparable and consistently appear together. Shoji participates in group activities like pestering Zenji Marui and utilizing Zenji's room for dormitory gatherings. His culinary background includes passing Fumio Daimido's entrance test for Polar Star Dormitory admission prior to the main series. Shoji maintains no specialized cooking style but possesses sufficient competence to endure Totsuki's rigorous standards. One known creation is fried shrimp, prepared as a simple snack. Shoji and Daigo share Polar Star's record for the longest interval between their manga debut in Chapter 7 and name revelation in Volume 9. They were the sole dormitory members excluded from Autumn Elections preliminary rounds and absent from Episode 19 when all other residents appeared. Shoji's given name uses kanji for "shining" (昭) and "two" (二), while his surname combines "assist" (佐) and "wisteria" (藤).
