The movie posters seem to use multiple fonts for its title and subtexts. The most familiar font available for the main title “Sailor Moon” is Wish MF from Richard William Mueller. The text “Crystal” is probably set in Oh You Klid by Nick Curtis. And the “Pretty Guardian” part is an italicized version of Hardly Worth It also by Nick Curtis.
