A 12-year-old girl who, along with three other children, is a "Lunarian", born and has lived her whole life on the Moon. Due to the effects of lower gravity, she appears to be twice her age due to her height. Her physiology is always examined as part of a study on the effect of being born and raised on the Moon. Once the study is finished, she wishes to only visit the Earth because she considers the Moon to be her home.
