Setsuna is the Princess of Pluto, and transforms into the Refomation Fighter, Sailor Pluto. In the second season of Sailor Moon, Sailor Pluto acts as a distant guardian for Rini while the young girl is in the 20th century. She has been charged to guard the Gate of Time with her key-shaped Garnet Rod. Sailor Pluto has the power to stop time (though using the power is forbidden), to correct time distortions, and to see into the future, but she does not usually divulge what lies ahead. Additionally, she can provide her allies access to the Time Warp, which allows them to travel back and fourth through time. Sailor Pluto is blunt and logical, which makes her seem cold and insensitive. Sailor Pluto leads a solitary life while guarding the Gate of Time, but seems to have a special place in her heart for Rini, who affectionately calls her Luna-P (or "puu" in Japan). In Bishojo Senshi Sailormoon S (third season), Sailor Pluto arrives on Earth as Setsuna Meioh to combine her talisman with those belonging to Sailor Uranus and Sailor Neptune. Setsuna returns in Sailor Stars to take baby Hotaru (Sailor Saturn) from Hotaru's father, Souichi.
