Pretty Sammy series
I do not know anything about this series because I have not seen any of the episodes.  Sorry.  The only thing that I know is that Ryo-ohki is her partner and can talk.   Also Sasami can say the magical chant and become The Magical Girl Pretty Sammy.  When ever I watch this series I will let you know how it is.  The character Pretty Sammy has appeared inone episode in both the OAV and tv series.
