Chibiusa

Chibiusa (ちびうさ?, or Rini in the English versions), is one of the central characters in the Sailor Moon metaseries and the youngest of the Sailor Senshi. When she first appears, she is a small child from the 30th century who visits the past to seek help from the series' primary heroines, the Sailor Senshi. She later returns, a few years older, in order to train as a Senshi herself—Sailor Chibi Moon (セーラーちびムーン, Sērā Chibi Mūn?, or Sailor Mini Moon in the English anime).
