In a parallel universe to our own, the fate of the world and the universe has fallen into the hands of a group of soldiers called the Sailor Senshi. There are a number of them, one for each planet, including a senshi for the moon and a knight for Earth. These senshi have faced many perils. The first of them was the famous Sailor V, who fought crime in England while searching for her past with the help of her guardian cat, Artemis. Her search led her to Tokyo, where she played as a decoy princess for Princess Serenity. She kept herself secret while four other senshi matured. They were Sailor Moon, Mercury, Mars, and Jupiter. Sailor V emerged later as the princess after a time but it wasn't long after that the real princess emerged, revealing herself to be Sailor Moon and causing the sought-after Imperium Silver Crystal to appear. Sailor V then became Sailor Venus, the leader of the senshi who protect the princess. Against the evil of Queen Beryl they fought. They were victorious and Princess Serenity was reunited with her captured prince, Prince Endymion.
A short amount of time passed peacefully before a new threat emerged from the future in the form of the Black Moon Clan. Their target was a helpless child from the future who's name was Chibi Usa. The 6 year old girl turned out to be none other than the child of Tsukino Usagi and Chiba Mamoru, also known as Sailor Moon and Tuxedo Kamen. The child turned out to be holding the Imperium Silver Crystal of the future which she had taken from her mother in order to grow up quicker. In an unsuccessful attempt to go into the future to fight the Black Moon Clan, the senshi met Sailor Pluto, the keeper of time. Shortly after they returned, Sailor Moon, in the final battle against the great evil, became the Sailor Moon of the future in order to defeat it. Chibi Usa used the Imperium Silver Crystal of the future to aid Sailor Moon and ended up becoming a Sailor Senshi herself by the name of Sailor Chibi Moon. Together, they defeated the Black Moon Clan. Afterward, Chibi Usa returned home and peace again came.
Little did the senshi realize that another evil had already been growing under their noses. Within the body of a little girl at Mugen Gakuen the soul of an evil called Mistress Nine was waiting. Much to the surprise of the senshi, Chibi Usa returned in order to train as a Sailor Senshi. While there, the Witches 5 began searching for the pure heart crystal that would allow Mistress Nine to awaken. Meanwhile, two new senshi appeared in the forms of Sailor Neptune and Sailor Uranus. Chibi Usa befriended a girl named Tomoe Hotaru. The first of the witches five sought out the Holy Grail, which was brought to life when the three talismans came together. Two of the talismans, the mirror and the sword, were within the pure heart crystals of Sailor Neptune and Sailor Uranus, respectively. The third talisman was the garnet orb atop the time staff of Sailor Pluto, who emerged to aid Neptune and Uranus. The Holy Grail fell into the hands of Sailor Moon, who used it to become her true Sailor form. As time went on, Uranus, Neptune, and Pluto held suspicions about Hotaru, who turned out to be Sailor Saturn. In a twist of fate, Sailor Chibi Moon's pure heart crystal fell into evil hands. With it, Mistress Nine emerged from Hotaru's body. When Uranus, Neptune, and Pluto were backed into a corner and almost killed, Pluto used her forbidden power to stop time and rescue Neptune and Uranus. Mistress Nine destroyed the Holy Grail and soon after Hotaru prevailed against Mistress Nine, Then with Sailor Moon's help, Sailor Saturn destroyed Pharaoh 90. Saturn died, but by the power of the Imperium Silver Crystal, Saturn was sent to be reborn at a later time and Sailor Pluto's life was restored.
Finally, peace had come, leaving the senshi to grow up, complete school, and be normal girls. After graduation, the girls pursued their dreams. Sailor Jupiter, Kino Makoto, married first of the senshi to a man named Kigino Shinzou, who helped Makoto get her own flower shop. Sailor Mars, Hino Rei, began a calligraphy class after marrying Seino Yuuki, a Shinto priest and teacher. Sailor Mercury, Mizuno Ami, married a doctor by the name of Okino Kiri after becoming a doctor, herself. Sailor Moon, Tsukino Usagi, married Chiba Mamoru, Tuxedo Mask, finally fulfilling vows they had made to each other in their past life. Sailor Venus, Aino Minako, was the last of the senshi to marry after spending a few years brooding over a prophecy that said she would never find love. Her love from her past life, a villain whom she had killed in England, came back without explanation. They married soon after. Minako became a housewife while her husband, Jino Kaitou became a rock star.
The other senshi, Pluto, Neptune, and Uranus, went about life differently. While in Tokyo they began a cooking class. When they weren't teaching, they were doing what they each loved to do. Sailor Uranus, Tenou Haruka, was often found racing on anything fast. Sailor Neptune, Kaiou Michiru, played her violin for both great crowds and small audiences. Sailor Pluto, Meiou Setsuna, divided her time between her life and her duty at the gate of time, spending her free time at either Michiru's concerts or Haruka's various races. In later years, she spent her free time taking care of her adopted children.
Tomoe Hotaru was reborn in the same year as Chibi Usa. The parents Hotaru was born unto was never discovered, as she was promptly taken into the care of Setsuna, Haruka, and Michiru.
Pink-haired, red-eyed Chibi Usa was born in 1983 to Chiba Mamoru and Usagi.1987 brought three more children into the lives of the senshi. Seino Rei gave birth to Naien in April, a mirror beauty of her mother. In May came Reikon, son of Jino Minako. To Okino Ami came Kogarashi in the month of September, who had blue hair and blue eyes like his mother.
Not long after Ami gave birth to Kogarashi did she again become pregnant. She was two months premature due to prenatal complications. In August of 1988, Aisu was born. She was born with blue hair that became white within three months of her birth, making her the apple of her naturally-white-haired father's eye. Minako also gave birth to a daughter, bringing Seirei into the world three months after Aisu, in the last week of November. Two weeks before Seirei was born, Kigino Makoto gave birth to her first daughter, Tenka. To add to the three births, Tenou Haruka surprised everyone, including Michiru and Setsuna, by adopting a four-month old baby girl by the name of Kainashi.
In 1990 came the second daughter of Usagi and Mamoru, pink-haired, blue-eyed Kousagi, in the month of June. Also that year came Seino Kaen, Okino Rikka, Jino Kinpa, and Kigino Hana in the months of March, August, October, and December, respectively. Michiru made an adoption in December for a ten-month old baby girl she named Shizuka.
The many children grew up like normal children do. In 1998 Minako gave birth to another daughter who was named Hikari. Setsuna adopted a two-year old boy named Hanshi and Haruka adopted an eight-year old boy named Wakai. After that, no more children were born to the senshi and no more children were adopted. Things went about normally for another six years. Then, in the year 2004, the simple lives of the children changed.
