Wiseman has now transformed Rini into Wicked Lady, by convincing her that she is all alone. Despite the Scout's attempts to convince her that they love her, he constantly uses his words as well as the Dark Crystal power to keep her under control.
Wicked Lady plans to use the power of the Dark Crystal to destroy the Earth, along with herself too. Serena then uses the Silver Crystal to transform into Neo Queen Serenity, and convinces Wicked Lady that they had always loved her all along. Reminiscing over the good times she has shared with the Scouts, Wicked Lady changes back into Rini.

With Serena's energy drained from the Silver Crystal's power, Wiseman uses the Dark Crystal's power to open the Dark Gates on Earth. Serena rises and uses the little power she has to transform into Neo Queen Serenity to defeat Wiseman.

The Silver Crystal's energy doesn't seem to be enough against the Dark Crystal as Serena stands alone against Wiseman. When Rini begins to blame herself for the battle, she remembers that back in the Silver Moon Millenium, the other Silver Crystal that she thought she lost had been placed inside of her body. She then uses it to transform, and Wiseman is shocked at the sight of two Silver Crystals. With the power of the Scouts and the two Silver Crystals, Wiseman is finally defeated.

With the Earth now safe, Rini has to say goodbye to the Scouts and go back home to the Silver Millenium. In the Millenium, Neo Queen Serenity has awoken from her slumber and is waiting for Rini along with Endymion and the rest of the Scouts. They welcome her home and Serenity tells Rini that she saved their world.
