The sailor senshi first encountered Sailor Pluto upon arrival in the Silver Millennium era. Sailor Pluto appeared to everyone guarding the Door of Space-Time.
She is the only senshi to have existed before all the others and has the most important duty among the sailor senshis. She must never leave her post and for it would cost her her life. She once did the taboo. However, being the soldier of time, she was immediately reincarnated as Setsuna Meioh to present-day Tokyo for a much bigger mission.
Sailor Pluto is considered a dear friend of Chibiusa who seems to be the only human to visit her often as she watches over the Door of Space-Time. She also has an unrequited love for King Endymion.
Sailor Pluto has the power not just over space and time but also the underworld as reference to the Roman myth god, Pluto. Unlike any other attacks in the series, hers is whispered rather than shouted when used. Her Garnet Orb, one of three talismans kept by the outer senshis is the source of her power. It rests on top of the Garnet Rod, a key-like staff symbolic of her duty.
In Silver Millennium, Queen Serenity gave her three “taboos” as the senshi of time: she must not travel through time, she must not abandon her post at the Door, and she must never cause time to stop.
