Chibiusa (ちびうさ, Chibiusa or Rini in the English versions), is one of the central characters in the Sailor Moon metaseries. 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?) (called Sailor Mini Moon in the English anime).
