Ішіхара Нобуко

Fashionable and charming, Nobu is Risa's best friend. She is generally wiser than Risa or Chiharu in the ways of love, and is always ready to offer her advice. She's mostly the one who sets up all the "alone time"; moments with Risa and Otani, but it usually ends up failing and Risa goes back to her for comfort.
