In the anime, Lettuce has a younger brother named Uri. She also made dolls as a pastime. Her parents, Yomogi and Eizaburou Midorikawa, always encouraged her to be herself, and someday, she will have real friends. Lettuce still had her so-called 'friends' from school, called the "Three Beckys" in the English dub, though she still has not told them she is a Mew Mew.
