A short-haired girl with large, captivating eyes, Kao is slightly tired and a bit stiff at first, but once she starts talking, she reveals a surprisingly warm and friendly personality. It's adorable how she shyly undresses herself. Having never experienced masturbation before, she nervously picks up the vibrator and gradually begins to let go. Her innocent, playful exploration of her body is utterly charming and deeply soothing to watch.
