Kotoko is a slim and petite girl with a blonde bob haircut. Kotoko's face is that of an angel who came from above and down to earth. Kotoko is not only an angel-face but she has a nice and bright personality as well. Kotoko can easily be friends with everyone if she wants to. Though she can be a bit clumsy and clueless sometimes which only adds to her cuteness. She gets pouty and sulky when things don't go her way. Either way, she's still very nice and affectionate.
