Keiko Matsunaga is the school nurse of the highschool Takuya goes to.
She has long wavy hair that extends to her waist and dark eyes. She has a very ideal hourglass figure, with large breasts and wide hips. She is often seen wearing a tight purple top which accentuates her breasts and a short black skirt held in place by a brown belt with a gold buckle, thus exposing her belly button. Over all of this she dons a large lab coat. She wears a pair of ear-rings that are thin gold rings.
