One day, a 14-year-old middle school underachiever named Usagi Tsukino rescues a cat from being harassed by young boys while running late to school. After school, she and her friend Naru Osaka visit a local jewelry store owned by the latter's mother. After encountering Mamoru Chiba, the cat appears again and speaks; she introduces herself as Luna and gives Usagi a brooch that allows her to transform into Sailor Moon. Usagi then hears Naru in distress when attacked by the monster Morga, who imper
Jadeite has a new plan to gather energy from humans: together with the monster Furau, he creates a late-night radio show called "Line to the Heart". Homeroom teacher Haruna Sakurada and Naru submit love-letters to the radio show, and they receive a pin that absorbs their energy. When they fall into a coma-like sleep, Usagi must investigate the radio station undercover. Luna gives Usagi a new accessory, a "Transformation Pen" to transform into any kind of professional. When she transforms into a
Usagi gains a couple of pounds and starts obsessing about her weight. Jadeite starts a dubious health club to drain energy out of people and mind-controls three bodybuilders to help him run it. Usagi and her friends sign up after seeing how much weight Ms. Haruna has lost. Luna suspects that Ms. Haruna has fallen victim to the enemy and tries to convince a resigned Usagi to transform and help her. Usagi discovers tanks in the basement which are stealing life energy from people. As Sailor Moon, s
Jadeite sets up a talent contest and has a human celebrity incapacitated and impersonated by the monster Derella, who hypnotizes people to get them to enter the contest. Luna notices that people are skiving their usual activities to practice for the contest. Usagi, though terrified of facing Derella, transforms into Sailor Moon. Derella encases her in ice, but Tuxedo Mask breaks it and Sailor Moon defeats the monster.
Luna senses a strange aura around Usagi's genius classmate, Ami Mizuno, and thinks she might be a Dark Kingdom spy. Ami Mizuno is a very intelligent, reserved girl who is often seen alone at school. In the hope that Ami will help her improve her school performance, Usagi befriends her and invites her to the game center. Ami leaves a floppy disk in the game center; Luna and Usagi discover that it is an artifact from the Dark Kingdom and mistake her for an enemy. However when a monster attacks Lun
Jadeite's new plan is to make humans work harder to increase their energy output with the help of Ramua, a monster that can manipulate time. Usagi's mother buys a new clock for her that drains her energy; Ami, now awakened as Sailor Mercury, helps Luna investigate. When Sailor Moon and Sailor Mercury meet they confront Ramua and Tuxedo Mask helps them defeat her by undoing the time spell with a rose.
Jadeite disguises himself as a servant in the nearby Hikawa Shrine to trick girls into using a bus that takes them to another dimension. Loaded buses are disappearing near the shrine, and most of Usagi's peers suspect that Rei Hino, a mysterious priestess at the shrine with strange psychic abilities, has something to do with it. The police also suspect the shrine's owners because the people who visit the shrine are the same ones who disappear on the bus. Jadeite sends Rei to another dimension af
Luna meets with Usagi, Ami and Rei in the Hikawa Shrine to remind them of their mission as Guardians. Usagi and Rei begin their combative friendship. Beryl becomes increasingly furious with Jadeite for his repeated failures; he starts up a theme park, but the general public notices the large number of disappearances. With the help of the monster Murido, known in the park as the "Princess of Dreams", who absorbs people's energy through an apple, Jadeite gathers a lot of energy. Mamoru also invest
Thetis, one of Beryl's monsters, offers to help Jadeite with his plans using a cruise ship enchanted by her powers. Rei wins tickets on the cruise ship and, since she has no boyfriend, asks Ami to accompany her. A jealous Usagi disguised as a photographer sneaks aboard after them.
Beryl gives Jadeite an ultimatum to defeat the Sailor Guardians, which prompts him to create an illusion in the sky and challenge the Guardians to fight him at the airport. Usagi continues to be romantically infatuated with both Motoki Furuhata and Tuxedo Mask. Later, at the airport, Jadeite puts the policemen to sleep and replaces them with clay golems. The Guardians fight the golems and encounter Jadeite, who taunts the guardians after taking on Tuxedo Mask and throwing him into the sea. The G
Nephrite, the second of the Four Kings of Heaven, takes over as Beryl's main energy gatherer. He plans to gather more strength and power from individual humans at their strongest, rather than from groups, and starts by targeting Rue, a tennis player who is Naru's childhood friend. He disguises himself as "Masato Sanjouin", a wealthy businessman and socialite. Usagi and Naru are excited when they see Masato Sanjouin arrive at the sports club, where he intervenes in a match to implant a monster in
Ami takes Usagi and Rei to see a park, and the caretaker tells them that it will soon be converted into an office building, with construction work already in progress. Usagi finally learns Mamoru's name, and that he is a university student; to her aggravation (and supposed jealousy), Rei decides to date him. Nephrite targets the caretaker's desire to protect nature, giving him the power to have animals attack the construction workers; when this is defeated, Rei suggests a similarity between Mamo
