Setsuna Meiou

Sailor Pluto is the soldier who guards the gates of time and acts as [Chibiusa's](https://anilist.co/character/2827/Chibiusa) 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. 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. 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
