榊 涼子

Ryouko 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. Ryouko'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.[From Wikipedia]
