Nana's best friend and is on the student council with her. She has made no secret of her distaste for Kaoru and has trouble getting his name right. This may be intentional as she had no problem getting it right when she was afraid she had offended his "girlfriend" after bad mouthing Kaoru. She has a massive crush on Hiroshi, but has not made her feeling on that clear to anyone other than Nana. She has a small dog named Hiro. She is seen walking him sometimes as a minor plot device.
