Satou is a chef and is considered a helpful but intimidating individual. He is in love with Yachiyo, but has problems expressing it. Of course, because she is so devoted to Kyouko, she fails to recognize any hints he attempts to make. He likes to take out his anger on Popura by messing with her or bending the truth, to which Popura naively believes. When Souma tries to help with Satou's development with Yachiyo, Satou unrelentingly hits him with a pan, showing that he is sensitive about his feelings for Yachiyo.
