Setsuna Meiou

Sailor Pluto is not introduced until late in the Sailor Moon R series. She is the soldier who guards the gates of time and acts as Chibiusas guardian. After the events of the second story arc she leaves the gates of time to temporarily live as a human being joins the rest of the Outer Senshi and becomes a university student studying physics. The exact nature of how she leaves her post differs between versions in the manga she is reincarnated in the present day by NeoQueen Serenity after sacrificing herself during the second arc while in the anime NeoQueen Serenity allows her to leave. Even in her civilian form Setsuna is the oldest of the Sailor Team around her late teens or older. Her personality has been described as distant and somewhat lonely however she does consistently display warmth and affection toward Chibiusa. When she reincarnates she becomes more friendly but is still not very emotional although there are moments in the manga where she expresses much more emotion than the anime. Unlike Sailor Neptune and Sailor Uranus she is sympathetic toward the Guardian Senshi and assists them on several occasions. During the second story arc she allows them to travel through time even though this is not ordinarily allowed. In the third story arc she often extends help or advice to Sailor Moon and her companions even when Sailors Uranus and Neptune want the two groups separate. Later Setsuna joins the Guardian Senshi in investigating the true identity of ChibiChibi. In the manga she is an inspiration to Ami and her relationship with Ami gives Sailor Mercury additional strength to power up to her Super form. Sailor Pluto is much darker in her initial form in the manga identified as the Guardian of the Underworld with very dark skin and a black sailor uniform. She is also stated to be the daughter of Chronos the god of time. She is a ruthless soldier who follows rather exacting laws executing any intruders who dare violate the underworld in search of the Gates of Time
