A UFO can be seen in the sky. Four sisters of the Dark Moon family and Rubeus look down upon Tokyo and plot its demise. Having renewed their love for each other, Usagi and Mamoru walk around and arrive at a dock. To their surprise, as they were kissi... (more)ng, a little pink-haired girl with a ""dumpling head""-style hairdo falls from the sky and lands on Usagi. The girl gets up and demands the Silver Crystal from Usagi. After Usagi denies her, the girl disappears. When Usagi gets home, she finds the girl, ChibiUsa, has moved into her house and brainwashed her family into thinking that she's Usagi's cousin! Her mother even shows her pictures to prove that ChibiUsa is a part of the family. The Warriors meet at Rei's shrine to try and discover something aboutthe mystery girl. ChibiUsa follows them and uses her magic to add sleeping powder to their tea. All the irls pass out except for Usagi, who was too busy stuffing her face with cake to bother with the tea. Koan appears and attacks both of them.
