Venus finally finds success in awakening her senshi powers and defeating the youma. And she decides to be operated on. Her friends the senshi, believing the operation will work out fine, plan a party. With a smiling face Minako heads toward the operation's inspection... Even though the odds are slim, Minako decides she's going to do the operation. And so that day comes a calling. The five of them beat the strongest youma; Naru, Motoki, and the other victims have returned to normal and the town's peace has been restored

Having been taught by Mamoru that the only way to protect the planet is to do it oneself, Usagi seeks to harness the power of the legendary Silver Crystal. Meanwhile Minako decides that, given how little remaining life she has left, she will quit singing and focus only on the completion of her previous existence's mission. Just as she is about to does this, she is informed by the office president that Minako's work will be taken over by a new face. Having suddenly snapped away her work, the identity of this new idol who appears before a surprised Minako is...

Usagi runs away from home and eventually winds up with Rei at her shrine. There, Luna sees a connection between the legend of Princess Kaguya and the real Moon Kingdom. Meanwhile, Zoisite formulates a plan to destroy all princesses under his hopes of defeating the Princess of the Moon.

Aino Minako (Sailor Venus) lets Rei in on an important secret. While Rei, having been told such a secret so suddenly, is unable to hide her shock, she doesn't have time to lose her bearings. Their enemies are growing stronger by the minute. As Rei and the rest are staying vigilant, the Dark Kingdom's ruler, Queen Beryl, having desired Endymion since their previous existence, has finally appeared in front of him.

Usagi Tsukino is a 14-year-old junior high student who unexpectedly becomes a heroine after a black cat, Luna, awakens her as Sailor Moon in order to save the world. First, she must save her friend, Naru Osaka, from an evil Youma inhabiting her mother's body.

Usagi suspects that a Karaoke Crown attendant named Motoki Furuhata is Tuxedo Mask when she discovers a tuxedo jacket with a hole in it like from the battle the night before, and impulsively brings him a gift. Makoto and Rei are invited along with them to an amusement park where they meet two of Motoki's friends - one of which is Mamoru Chiba. Things go well until a Youma attacks Rei, and Usagi unknowingly reveals to Mamoru that she is Sailor Moon.

As they enter summer vacation, some volunteer work pops up at Usagi's school. With her classmate Naru, Usagi, Ami, and Makoto help watching over kids at a children's home. While she doesn't know how to handle the kids, Usagi's got a particular scheme in mind. Without telling Makoto, she calls up Motoki and leaves the two alone. Not knowing anything, Makoto carries the children's dirty clothes to the backyard. ...where Motoki has just arrived.

There is a rumor that the Mystical Silver Crystal will be exhibited at a high-society costume party. Tuxedo Mask decides to look for it, followed by Usagi, but the Dark Kingdom is still one step ahead. Meanwhile, Rei refuses to cooperate with Usagi and Ami, choosing to act on her own.

Rei and Makoto get into a petty argument and when arriving to apologize, Makoto thinks Rei is being kidnapped. Meanwhile, Usagi works very hard for a mascot costume contest for pop idol, Minako Aino, and is attacked by Jadeite at the contest.

When Tuxedo Mask reveals information of the Mystical Silver Crystal to the public to speed up the search for it, the mad rush brings a wealthy businessman to ask for Rei's protection of his gem that seems authentic. Meanwhile, Usagi fights her feelings for Tuxedo Mask after being warned by Sailor V that he is the enemy and gets in big trouble for helping him.

Usagi faints as Kunzite's spell to transform her into a Youma comes back into affect. While Makoto and Rei run off to find Kunzite, Ami does her best to help Usagi fight back.

Usagi is overwhelmed by her feelings for Mamoru and decides to get over him by making a scarf for Tuxedo Mask. Meanwhile, Rei visits her mother's grave and runs into Minako... who she sees transform into Sailor Venus!

Even though Usagi decided to stop thinking about Mamoru, she runs into him in the street. After learning that he's leaving to study abroad Usagi is overjoyed, but when Hina reveals that he'd possibly been attacked by someone named Kunzite, Usagi leaps into action and runs to his rescue.

Finally, Usagi and Mamoru's affections have united. Although their love has been said to be cursed since their previous existence, seeing Usagi's delighted appearance, her friends cannot separate them, despite their personal unease. As opposed to Usagi, who's reached the summit of happiness, Ami has been always lonely due to being emotionally isolated from her mother, and Rei, with her father being a politician, has always been resentful of him. Yet the situation has presented itself in such a way that both will have to face off against their parents.

After school Usagi is walking home to find Mamoru standing on the other side of the bridge, they walk up to each other and he hugs her, then she starts crying out of happiness. later Mamoru kills Kunzite and turns into Dark Endymion meanwhile the other Senshi are fighting an Younma and some how they end up get attacked by Endymion. whilst the other Senshi are fighting the Younma Mio gets killed by Endymion and after the other Senshi were attacked he aims at Usagi and hits but Usagi turns into sailor moon. After sailor moon henshins (not exactly) she has a sword and Mamoru tells her to attack sailor moon looks at him and decides she will do so. in the end Usagi kills Endymion and whilst shes get her run up Makoto, Ami and Rei yell at Usagi not to do it but Usagi doesn't listen because she knows what she must do

After Sailor Moon has no choice but to kill Endymion, the Princess uses her power to destroy the world again, and the other Senshi are too late to stop it. Realizing that the world's demise was, in fact, the result of her selfishness, Serenity uses again the power of her love for Endymion to bring the world back to its original state, giving Usagi and Mamoru a second chance in life.

Usagi is saved by a new girl in town from the bullies. When Usagi realizes the girl who saved her is at her school, she befriends her. The new girl, a tomboyish Makoto Kino, seems tough on the outside, but when she lets her guard down for a popular basketball player who turns out to be a Youma in disguise, the vulnerable Makoto must awaken as Sailor Jupiter to defeat him.

Usagi aids Minako in escaping her manager and spend some quality time together. Later on, Sailor V reveals herself as Sailor Venus, princess of the Moon Kingdom.

Usagi and Mamoru had previously lived their lives deeply in love, as the Princess of the Moon and Prince of the Earth. Although in the present they have once again managed to meet due to their strong attraction, the love between the two of them cannot be allowed. Looking to find his true self, Mamoru has journeyed to London. Having given up on Mamoru, Usagi now decides to focus all her strength on regaining the dark-hearted Ami. Meanwhile, a single senshi appears in front of Ami. (Sailor Mercury.) Stating, ""I will surely restore you,"" who could this senshi be? And a mysterious girl also happens to appear in front of Usagi, Rei, and Makoto at the same time.

Facing Sailor Moon, Mamoru- as his previous-existence alter-ego Endymion- drew his sword! With the intention of not repeating the tragedy of their previous life, Endymion declared war upon Usagi. But Usagi's feelings will not change. She will gallantly continue to believe in Mamoru. Also, in a completely unexpected twist, Aino Minako's office president requests Usagi's mother to become a television reporter! (I prey they change this and get a nicer one)

Naru enters a coma after Princess Sailor Moon awakens again. Usagi conjectures that negative emotions fuel her power, so she tries her best to suppress such emotions.

Ami Mizuno is the highest ranked student in Usagi's class, and Usagi manages to befriend her despite their academic differences. But when Luna suspects that Ami might be Senshi as well, Ami also suspects that as the reason for Usagi's friendship and refuses. When she is attacked by a Youma, Ami realizes how true a friend Usagi is and awakens as Sailor Mercury.

Has Mamoru disappeared in London? Usagi can't take it anymore. And with that, Mio provides her with a heaven-sent opportunity ""You can go to London."" The question is, can Usagi dash to Mamoru's side? In that regard, wanting to go to London, Usagi finds it unbearable. In order to get to England she becomes the attendant of the popular actor Yuuto. But having played the mediator, enabling Usagi to do this, hmm... that Mio must be up to something! As it were, Mamoru flew to London like he was running away from something. But, even if he's in London, fate's not going to leave him alone. As Kunzite noted of the circumstances, ""What kind of meeting is this..."" How will Mamoru respond?

Since Ami was a child she has always suppressed herself and followed what her mother requested of her to make her mother happy. But even though her mother said it would be best to change schools, Ami is unable to suppress herself, as in the past, this one time. Meanwhile Rei remains unable to forgive her father the politician for not coming to the hospital when her mother was dying. What actions will these two, who hold such complex feelings toward their parents, take...?

Usagi, having lost Chiba Mamoru to Queen Beryl, must suppress her feelings of concern for him and believe in his return. And while Luna wasn't looking, Usagi disappeared! Since the last thing Luna had heard was a harp's note, Usagi must be in her Princess form. Relying on this note, the senshi begin their search for the Princess. Meanwhile Mamoru, taken to the Dark Kingdom, faces his retainers from his previous existence, the Shitennou.
