Plot
Helios introduces himself to Mamoru and the six super Sailor Senshi and tells Mamoru that he has been his guardian as well as the protector of Elysion. Helios tells them of how Nehellenia arrived and captured Helios and brought ruin to Elysion, causing both Helios and Mamoru to be cursed. He tells them that they need Super Sailor Moon to undo the seal on the Golden Crystal (which is revealed to be Prince Endymion/Mamoru's very own Crystal and the symbolized weapon of the infinite power of good or evil) all along, in order to save them. Meanwhile, Minako has been keeping her secret from the rest of the group that she cannot transform into Super Sailor Venus. Seeing her in a weakened state, the Amazoness Quartet decide that they should attack Minako, and send Xenotime and Zeolite after her.
Minako is approached by Xenotime disguising himself as a talent scout and asks Minako if she would like to join a competition to become an idol. Minako is aware that it is a trap but goes in any way to prove herself as the leader of the Sailor Senshi. The challenge that the twins set is to save children on a collapsible platform.
The other challengers become brainwashed by the Dead Moon Circus to be competitive. Before they can be hit by oncoming boulders, the other Sailor Senshi arrive to help and learn that Minako can't transform. The other Sailor Senshi try to stop Minako but are pinned down by knives thrown by one of the twins. Minako reaches the top, only to figure out that the children are really Lemures and attack her. The Lemures almost possess Minako, alarming Artemis; causing him to scratch her head like crazy. The Amazoness Quartet drops Minako through a trap door on the platform and Artemis grabs onto Minako to hold her up. PallaPalla creates a giant boulder and Minako watches helplessly as it is dropped on Artemis. She screams as she and Artemis are about to die.
