Pretty Guardian Sailor Moon

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.

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.

During a string of disappearances of miko priestesses, Usagi runs into one of them, Rei Hino, who is the prime suspect of the missing girls. Usagi defends her reputation, until the two got pulled into another dimension by a Youma, causing Rei to awaken as Sailor Mars.

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.

When Ami feels that her friendships with Usagi and Rei are not genuine, she reads a book on how to be a true friend. This causes friction between her and Usagi, and Ami gets into more trouble when she tries to defeat a Youma without calling for help.

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.
