There are multiple examples of art assets being censored in the North American release.
Esper Siren, Esper Starlet, Alluring Rider, Madam, The Goddess and Chadarnook's Godess part were all altered to be more acceptable to international audiences, mostly covering up more skin, or in Madam's case, removing smoking references.
Additionally, the Cafe sign originally read "Pub".
Many of these changes were kept in place in the Game Boy Advance port of the game.
