Sailor Saturn
All of Sailor Pluto's attacks require the use of the Garnet Rod, which is shaped like a giant key as a symbol of her stewardship over the Door of Space-Time. In Roman mythology, it is stated that the god Pluto holds a key because "they say that what is called Hades has been locked up by Pluto, and that nobody will return back again therefrom." Natale Conti cites Pausanias in noting that keys are an attribute of Pluto as the scepter is of Jove (Roman Zeus) and the trident of Neptune (Poseidon). The Pluto Crystal is perhaps her most important possession, as it is her Sailor Crystal and the source of all her power, which becomes especially important in the fifth story arc. It is given to her by Sailor Saturn.
