 The third series in the "Bishoujo Senshi Sailor Moon" trilogy. The Sailor senshi, "warriors," meets two other mysterious senshi, Sailor Uranus and Sailor Neptune, both whom are searching for pure hearts in humans, three of which contain three talismans which when found will help Uranus and Neptune get the Holy Grail, which, in the hands of the great Messiah, will protect the world and the future. However, Professor Tomoe, his Death Busters and the Witches 5 are after the very same thing. Also, Chibi-Usa, who left in "Sailor Moon R" to live with her parents in the future, returns--as a new Sailor senshi, Chibi Sailor Moon.
