It begins as Professor Tomoe is working in his lab. An accident occurs and it kills everyone but him. Soon a Demon Master finds him
and tells him he will revive Hotaru if he works for him. Tomoe agrees. He is then forced to search for Pure Heart Crystals
and The Holy Grail to create a gateway for Master Pharaoh 90 to come through. The Outer Sailor Senshi are introduced,
Sailor Uranus (Amara), Sailor Neptune (Michelle), Sailor Pluto (Trista), and Sailor Saturn, or the Sailor Scout of Destruction
(Hotaru), as well as Sailor Chibi Moon (Rini), who has come back from the future to train with Sailor Moon. Sailor Uranus, Neptune,
and Pluto are also looking for the pure heart crystals that once combined will form the Grail. Later they realize that they are
the holders of the pure heart crystals and create the grail in which Sailor Moon is given a new transformation. Hotaru is then
transformed into Mistress 9 and gains the power to open the gateway for Mistress Pharoh 90 once eating Rini's pure heart. Once the
gateway is opened Hotaru then becomes Sailor Saturn and is able to defeat Mistress Pharoh 90 with her silence glave, she dies in the
process. Sailor Moon uses her own powers to revive Sailor Saturn into a baby and save Professor Tomoe giving them a second chance
for a normal life.
