Lilly Satou (砂藤リリー, Satō Rirī) is one of the five main female characters of Katawa Shoujo. She often speaks in a very well-bred and formal manner, even to those she is close to. She is completely blind in both eyes, however, she never likes being pitied by anyone else in spite of her lack of vision, and as such has grown up strong-willed and independent. She enjoys being seen as someone people can look up to, and acts very motherly to many people around her, be it Hanako, Hisao, or the members of her class.
