The season is divided into two arcs: One arc being an anime filler (to give Takeuchi Naoko time to make the next manga), and the other arc being the actual Black Moon plot. The first arc shows Usagi and Co. having their memories restored from the first season. Their enemies are a pair of aliens, Ail and Ann, who are seeking human energy to restore their life tree. Mamoru had yet to recover his memories and he appeared as the Moonlight Knight rather than Tuxedo Kamen. This arc only lasted for 13 episodes. The second arc introduces Chibi-Usa, a little girl from the future who is searching for the Silver Crystal. The new enemies are the Black Moon Clan, comprising of the Ayakashi sisters (Cooan, Beruche, Karaberas, and Petz), Rubeus, Safir, Esmeraude, Prince Demando, and Wiseman. They too want the Silver Crystal so that they can take over the future. The Sailor Senshi's adventure continues...

When Mamoru was little he gave a rose to a little boy named Fiore. Fiore promised that one day he would bring Mamoru lots of flowers. Now Fiore has come back to earth but his intentions are not merely to fulfil a promise...

However, Kira, the shooting star, and Maya, the fuuga, did not attend the selection tests and left for the Earth.The six angels fulfilled their tasks faithfully.

Long ago there was a war in Heaven which resulted in Judas and Luca – two of the six specially-chosen, talented and strong Saint Beasts – being cast out and imprisoned in Hell for leading the rebellion. But before that Heaven had been a peaceful place where the angels happily lived their lives. In this time, Judas, Luca, Goh, Shin, Rey and Gai are adolescent angels in Heaven who, on the day of Benediction, are made into adults by the supreme god Zeus. With each of the six having their own special abilities and new adult bodies to get used to, opportunities to meet each other arise and new friendships are formed.
