Runa Shirakawa is a cute gyaru, who loves tapioca. She’s often regarded as the hottest girl in the year. She’s 17. She’s never had a proper relationship; every guy she’s “dated” has been intimate with her, and then left afterwards, taking advantage of her innocence. A bubbly and sweet girl, she overlooks this, and thinks it’s normal for that to happen. She has light blonde hair with blue dyed tips and blue eyes. She’s carefree, but caring as well.
