One day, Usagi Tsukino, clumsy 2nd-year middle school student, stumbles upon a talking cat named Luna. Luna tells her that she is destined to be Sailor Moon, "champion of love and justice", and she must search for the fabled Moon Princess. Usagi finds friends that turn out to be destined senshi as well, and together they fight to save the world from the certain doom brought upon by the Dark Kingdom.
Queen Beryl partially awakens the evil entity Metalia and sends Zoisite and Kunzite to find the Seven Great Youma and their Rainbow Crystals. Meanwhile, the tomboyish Makoto Kino transfers into Usagi's school and falls for a crane-game whiz at the arcade.
Naru is still very depressed after Nephrite's death. Usagi and Umino decide to take her to Yokohama to cheer her up. There, a kindly priest is attacked by Zoisite. Mamoru realizes that he is Tuxedo Mask, and drops a locket on the ground, where Usagi finds it.
Ami meets Ryo Urawa, a clairvoyant boy who has a crush on her. However, Urawa's power makes him aware that he will soon be transformed into a Youma by Zoisite.
Usagi and Mamoru are asked to model for the reclusive painter Yumemi Yumeno, who is unexpectedly targeted by Zoisite.
Makoto, like Usagi, develops a crush on Motoki. The two then decide to pursue him simultaneously, even after finding out that he has a girlfriend, who, meanwhile, is targeted by Zoisite and Kunzite.
After fighting off an attack by Zoisite, Rei's grandfather takes on an apprentice and begins acting strangely.
