Like the other senshi of Sailor Moon, Sailor Neptune and Sailor Uranus were once princesses on their respective planets and had been given their own castles at birth by Queen Serenity of the Silver Millennium. Princess Neptune received theCastle Triton on the planet Neptune. Princess Uranus received theCastle Miranda on the planet Uranus. In Sailor Moon Stars (manga only), Sailors Neptune, Uranus, and Pluto once again visit their castles (although it doesn't turn out too well, as Galaxia appears shortly thereafter to take their star seeds).
