The season begins with a dream that Rini is having about a unicorn that is actually Helios. Helios has chosen Rini to live in her
innocent dreams and must make sure that she tells no one about him. However, a strange circuse group comes to town that is also
in search of Helios. With his power they would be able to control the world. However Helios was able to escape by living in other's
dreams. Zirconia was the leader of the Dead Moon Circus and gave order to the Amazon Trio and Amazoness Quartet. Zirconia worked
for Queen Neherenia. Though the Amazon Trio failed but with Sailor Moon's help she set them free and the Amazoness Quartet also
failed but they were actually the Astroid Senshi and were also set free. Once Pegases, the form Helios took, gave the Sailor Senshi
power to transform into super sailor scouots they were able to defeat the Dead Moon Circus and free Helios from bondage. Most of
this season revolves around Rini.
