土萌螢
According to the manga, on Silver Millennium, Sailor Saturn was also the princess of her home planet. She was among those given the duty of protecting the Solar System's Outer Planets (Uranus, Neptune, Pluto and Saturn). As Princess Saturn, she dwelt in Titan Castle and wore a purple gown—she appears in this form in the original manga and in supplementary art. Unlike the other Sailor Guardians, it is stated that Saturn did not awaken on Silver Millennium until after it was destroyed so Princess Saturn's exact status during that time is unclear.
