Sailor Moon #5

In Juban, Tokyo, a middle-school student named Usagi Tsukino befriends Luna, a talking black cat who gives her a magical brooch enabling her to transform into Sailor Moon: a soldier destined to save Earth from the forces of evil. Luna and Usagi assemble a team of fellow Sailor Soldiers to find their princess and the Silver Crystal. They encounter the studious Ami Mizuno, who awakens as Sailor Mercury; Rei Hino, a local Shinto shrine maiden who awakens as Sailor Mars; Makoto Kino, a tall and strong transfer student who awakens as Sailor Jupiter; and Minako Aino, a young aspiring idol who had awakened as Sailor Venus a few months prior, accompanied by her talking feline companion Artemis. Additionally, they befriend Mamoru Chiba, a high school student who assists them on occasion as Tuxedo Mask.

In the first arc, the group battles the Dark Kingdom. Led by Queen Beryl, a team of generals—the Four Kings of Heaven (四天王, Shiten'ō, lit. "Four Heavenly Kings")—attempt to find the Silver Crystal and free an imprisoned, evil entity called Queen Metaria. Usagi and her team discover that in their previous lives they were members of the ancient Moon Kingdom in a period of time called the Silver Millennium. The Dark Kingdom waged war against them, resulting in the destruction of the Moon Kingdom. Its ruler Queen Serenity later sent her daughter Princess Serenity, her protectors the Sailor Soldiers, their feline advisers Luna and Artemis, and the princess' true love Prince Endymion into the future to be reborn through the power of the Silver Crystal. The team recognizes Usagi as the reincarnated Serenity and Mamoru as Endymion.
