Ryōko is a tall, mature-looking girl with long purple hair, orange eyes, and a large bust. She is gentle and kind, responding to the eccentrics of the other Polar Star residents in a level-headed manner and comforting the other students when they are troubled. Ryōko's specialty is fermented foods due to her parents owning a well-known fermented-goods shop, and she maintains a workshop near the dorms to produce her own ingredients. She also keeps a bottle of "fermented rice drink" that she would sometimes bring out during parties and celebrations, which Sōma suspects is illegally brewed sake.
~!During the Autumn Elections, she presented a "curry soy-natto rice" using charcoal-fermented natto and homemade rice-sauce fermented with koji. The dish garnered praise from the judges, who suddenly felt as if they were in a festival due to the quintessentially Japanese and festive taste of the dish. She ultimately took 7th place in her block.!~
