Ryouko Sakaki

Ryouko 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 Souma suspects is illegally brewed sake.
