In a dark room in a spaceship above Tokyo, a man and four girls - Rubeus and the Negamoon Sisters - are looking for someone, and the Imperium Silver Crystal, and have traveled to the past to find them.
Meanwhile, Serena and Darien are enjoying a romantic boat ride, but afterward, a girl with pink hair named Rini falls from the sky and demands that Serena give her the Silver Crystal. They refuse, so when Serena gets home, she sees that Rini has brainwashed her family into thinking that she is Serena's cousin, using a Luna Sphere that resembles Luna (though Luna says it does not look anything like her).
Serena takes one of the photos featuring Rini with her family so Raye can get a reading on it in the fire. Raye can't get much from it, and while they are hanging out in Raye's room, Rini drugs Grandpa Hino, and does the same to Amy, Raye, Lita, and Mina. However, because she is busy stuffing herself with muffins, Serena avoids the same fate, and prepares to punish Rini, but before she can, the stress of the situation causes the crescent moon mark of the Royal Family of the Moon Kingdom to appear on Rini's forehead and emit a beam into the sky.
Meanwhile, a hooded figure named Wiseman talks with Rubeus and the Negamoon Sisters, and Rubeus sends one of them, Catzi, to capture Rini. When Catzi spots the beam Rini emitted, she attacks Rini, however, Serena transforms into Sailor Moon and fights her off, along with Tuxedo Mask. She uses Moon Scepter Elimination on Catzi, which misses her. Catzi teleports away.
Rubeus, Wiseman, and the Negamoon Sisters want to destroy Crystal Tokyo of the future, which is why they are attacking it here, while Serena begins to dislike Rini less than before.
