14-year-old crybaby Tsukino Usagi is always late, irresponsible, is boy-crazy, never serious and gluttonous. She's chosen by the talking guardian cat Luna as the leader Sailor Senshi, Sailor Moon. As Sailor Moon, Usagi must fight the evil of Queen Beryl and the Dark Kingdom and locate/protect the Moon Princess. She's joined by Ami, Rei, Makoto and Minako, the other four (more serious) Sailor Senshi. The senshi is occasionally rescued by the mysterious Tuxedo Kamen.
