Once again, the scene opens in the Dark Kingdom, Jadeite being rebuked by Queen Beryl for failing twice. Another warrior, Nephrite, boasts that he could do better. As the warriors gather around the queen, they question her as to what the Silver Imperium Crystal is. She informs them it is a source of endless energy, the one who has it controls the universe. She gives Jadeite one last chance to redeem himself.

A beautiful young Japanese priestess meditates before a fire. Her name is Raye and she is sensing something evil is coming. As a group leaves the shrine at Sendai Hill, we realize the driver is none other than Jadeite. When Raye turns around, the bus vanishes as it drives away.

The next day, Bunny is sleeping on her desk at school. Luna wakes her up, and talks her into a planning meeting with Amy by saying it's to be held at the video arcade.

At the meeting, Luna talks to Amy while the Sailor V game distracts Bunny. Luna tells Amy of their need to find the princess and the Silver Imperium Crystal. After Bunny wins a level of the game, a prize of watches comes out, which Luna informs them as being remote communicators for them to use.

Amy leaves the arcade, needing to go study, and Bunny follows her unto the bus, where they see the priestess Raye. Bunny is mesmerized by her and follows her to Sendai Hill, even after Amy leaves. After following Raye to the temple, Bunny is attacked by a group of crows. This leads Raye to believe there is an evil spirit. After throwing her paper scroll, Raye realizes she made a mistake, it was just a girl and not a demon. Bunny is a little scared, but still thinks Raye is exotic and pretty and hopes they can be friends. The crowd whispers about Raye and the temple's connection to the "Phantom Bus" disappearances, but Luna wonders if she may be the princess.

In the Dark Kingdom, Jadeite has been collecting the girls that have disappeared on the bus to use as bait for Sailor Moon. He hopes to give both the humans and the Sailor Scout to the great master.

At school, people talk about the vanishing buses, which Luna thinks the enemy may have a connection to. She urges Bunny to check out the temple again and they take the bus up to Sendai Hill. On the bus, Luna tells Bunny she can contact Amy, and then starts wiggling a meowing, and Bunny asks what she was saying. Then, we see the same guy Bunny keeps running into sitting close by, jokingly telling Luna to "go ahead and say it." Bunny freaks and asks him why he is there. He pulls out his id and we learn his name is Darien Shields, a high school student who takes this bus to school. His profile reminds Bunny of Tuxedo Mask, and he looks at her and murmurs "champion of justice". Bunny and Luna are both freaked out, thinking he's to sharp and may eventually figure out her identity.

At Sendai Hill, a crowd gathers, asking Raye to find the missing girls. They even go so far as to accuse her of being a part of the mystery. She sends them all home, and Bunny feels sorry for her, while wondering why the enemy does not appear to be searching for the Silver Imperium Crystal.

Raye once again meditates before her fire in the shrine. She sees the enemy grabbing Bunny and senses the danger. This leads her to run for the bus, where she realizes the driver is the enemy from her vision. Jadeite forces her onto the bus.

As Bunny and Luna walk down the street, they see the bus pass by, with Raye unconscious in one of the windows. Bunny morphs into a stewardess, and grabs unto the disappearing bus. Luna falls off, and lands in Tuxedo Mask's arms. Bunny disappears with the bus, leaving Tuxedo Mask and Luna behind.

Bunny is in the Dark Kingdom, but can still talk to Luna and Amy through their communicators. Luna tells Bunny to morph and Amy morphs while Luna warps her to Bunny's position.

Jadeite has grabbed Raye and Sailor Mercury uses her fog, which is frozen into crystals by Jadeite and falls uselessly to the ground. Luna tells Sailor Moon not to cry, but attack. She uses her frisbee attack, which Jadeite blocks, but then it encircles him, trapping him by surprise.

The symbol of the planet Mars appears on Raye's forehead. Luna gives her a pen and she morphs into Sailor Mars. Using her fire, Sailor Mars burns Jadeite to a crisp. They gather everyone captured and Luna warps them back to the temple.

Sailor Mars is a bit disoriented by her discovery, but Sailor Moon and Mercury are happy to have found another scout. Back on the Dark Kingdom, Nephrite is enraged by the fate of the warrior Jadeite.
