Granny (what Gokudo calls her) is actually one of the many disguises of the Magic Queen, Prince Niari's mother. Throughout the show, she cons Gokudo and Company into doing her many "chores", which result in the group getting into wacky escapades at every turn. Also, she seems to have a crush, if you will, on Gokudo because she is always disguising herself as an attractive woman to get his attentions.
